General anesthesia (GA) is typically recommended for category 1 emergency cesarean delivery (CD). For categories 2-4 emergencies, either regional or GA can be used. The factors influencing the choice of anesthetic technique in these categories remain poorly understood. We analyzed the association between the type of labor analgesia and subsequent anesthetic techniques employed for intrapartum categories 2 and 3 CD. In a prospective longitudinal cohort study, 300 women were consequently enrolled and categorized according to Lucas's classification of CD urgency. The techniques of anesthesia (GA, spinal, and epidural anesthesia [EA]) employed for CD were analyzed with respect to labor analgesia methods (remifentanil patient-controlled analgesia [remifentanil-PCA], EA, and nitrous oxide [N2O]). EA was the most frequent analgesic option (43.8%), followed by remifentanil-PCA (20.7%) and N2O (5.1%), while 30.4% of parturient women received no analgesia. All anesthetic methods showed a significant relationship with analgesic modalities (P < 0.001). Remifentanil-PCA was associated with a higher incidence of GA. Contraindication to EA was the primary factor related to the transition from remifentanil-PCA to GA. Most parturients who received EA were successfully converted to EA. Spinal anesthesia was the most common technique in women using N2O and those without labor analgesia. GA was associated with lower 5-min Apgar scores. The method of labor analgesia was associated with the anesthesia technique employed for categories 2 and 3 CD. This finding may guide patient counseling and intrapartum anesthetic planning. However, the analysis should be cautiously interpreted as the selection of anesthesia is a complex decision influenced by several clinical considerations.

Objective: To compare the maternal and neonatal morbidity in patients with transvaginal (TVC) versus transabdominal (TAC) cerclage., Materials and Methods: Retrospective analysis of patients who received cervical cerclage and terminated the pregnancy in the second trimester or third trimester in two tertiary hospitals. Data on basic clinical characteristics, predelivery maternal morbidity, intrapartum morbidity, postpartum morbidity and neonatal morbidity of TVC patients and TAC patients were analysed and compared., Results: Seventy-two TVC patients and 120 TAC patients were included. The rates of abnormal fetal presentation and placental disorders were significantly higher in TAC patients than that in TVC patients (21.67% vs 5.56% and 18.33% vs 4.17%, respectively). The rates of premature rupture of membranes and intrauterine infection were significantly higher in TVC patients than that in TAC patients (25.00% vs 2.50% and 11.23% vs 3.33%, respectively). Compared with TVC patients, the rates of estimated intrapartum hemorrhage ≥500 ml, uterine rupture and cesarean delivery in the third trimester were significantly higher in TAC patients than in TVC patients. Gestational age at delivery and neonatal morbidity were comparable between TVC patients and TAC patients., Conclusion: Compared with TVC patients, TAC patients were associated with a significantly higher incidence of maternal morbidity in placental disorders, abnormal fetal presentation, intrapartum hemorrhage ≥500 ml and uterine rupture., Competing Interests: Declaration of competing interest We declare that there are no potential conflicts of interest., (Copyright © 2024.

Background: The rising rate of cesarean deliveries has led to an increased incidence of long long-term complications, including niche formation in the uterine scar. Niche development is associated with various gynecologic complaints and complications in subsequent pregnancies, such as uterine rupture and placenta accreta spectrum disorders. Although uterine closure technique is considered a potential risk factor for niche development, consensus on the optimal technique remains elusive., Objective: We aimed to evaluate the effect of single-layer vs double-layer closure of the uterine incision on live birth rate at a 3-year follow-up with secondary objectives focusing on gynecologic, fertility, and obstetrical outcomes at the same follow-up., Study Design: A multicenter, double-blind, randomized controlled trial was performed at 32 hospitals in the Netherlands. Women ≥18 years old undergoing a first cesarean delivery were randomly assigned (1:1) to receive either single-layer or double-layer closure of the uterine incision. The primary outcome of the long-term follow-up was the live birth rate; with secondary outcomes, including pregnancy rate, the need for fertility treatment, mode of delivery, and obstetrical and gynecologic complications. This trial is registered on the International Clinical Trials Registry Platform www.who.int (NTR5480; trial finished)., Results: Between 2016 and 2018, the 2Close study randomly assigned 2292 women, with 830 of 1144 and 818 of 1148 responding to the 3-year questionnaire in the single-layer and double-layer closure. No differences were observed in live birth rates; also there were no differences in pregnancy rate, need for fertility treatments, mode of delivery, or uterine ruptures in subsequent pregnancies. High rates of gynecologic symptoms, including spotting (30%-32%), dysmenorrhea (47%-49%), and sexual dysfunction (Female Sexual Function Index score, 23) are reported in both groups., Conclusion: The study did not demonstrate the superiority of double-layer closure over single-layer closure in terms of reproductive outcomes after a first cesarean delivery. This challenges the current recommendation favoring double-layer closure, and we propose that surgeons can choose their preferred technique. Furthermore, the high risk of gynecologic symptoms after a cesarean delivery should be discussed with patients., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

Introduction: Transversus abdominis plane (TAP) blocks are commonly performed for postoperative analgesia in elective cesarean section. Ropivacaine is the most commonly used local anesthetic for TAP blocks. Currently, the concentration of ropivacaine for TAP blocks is various, and increasing number of randomized controlled trials (RCTs) have compared the effects of different concentration of ropivacaine for TAP blocks in cesarean section. This protocol of a systematic review and meta-analysis aims to identify the optimal concentration of ropivacaine for TAP blocks in elective cesarean section., Methods and Analysis: Databases including PubMed, Web of science, the Cochrane library, and EMBASE will be searched from their inception to May 1, 2024. RCTs that investigated the analgesia of different concentrations of ropivacaine for TAP blocks in elective cesarean section will be identified. The analgesia duration will be the primary outcome. Secondary outcomes will include the analgesics consumption over postoperative 24 hours, postoperative pain scores at rest and movement, and the incidence of adverse effects. RevMan 5.4 software will used for statistical analysis. The evidence quality of synthesized results will be evaluated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach., Ethics and Dissemination: Ethical approval is not applicable. The results of this study will be published on completion., Trial Registration: PROSPERO registration number: CRD42024496907., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Zhang et al.

Background: Respiratory functions may be impaired in cesarean section (C/S) delivery performed under spinal anesthesia (SA) and oxygen supplementation may be required. Therefore, we conducted a randomized controlled study aimed to evaluate the effects of different oxygen administrations in pregnant women on the lungs during C/S under SA using ultrasound and oxygen reserve index (ORI)., Methods: We conducted a randomized, controlled, single-center study from May 1, 2021, to March 31, 2022. A total of 90 patients scheduled for C/S under SA were randomly divided into 3 groups. Following the SA, patients in group 0 were treated with room air, in Group 3 were administered 3 L/min O₂ with a nasal cannula (NC), in Group 6 were administered 6 L/min O₂ with a simple face mask. In addition to routine monitoring, ORI values were measured. Lung aeration was evaluated through the modified lung ultrasound score (LUS) before the procedure (T0), at minute 0 (T1), 20 (T2), and hour 6 (T3) after the procedure, and ∆LUS values were recorded., Results: After SA, the ORI values of Group 3 were higher than Group 0 at all times (p < 0.05), while the intraoperative 1st minute and the 10th, 25th and 40th minutes after delivery (p = 0.001, p = 0.027, p = 0.001, p = 0.019) was higher than Group 6. When the LUS values of each group were compared with the T0 values a decrease was observed in Group 3 and Group 6 (p < 0.001, p = 0.016). While ∆LUS values were always higher in Group 3 than in Group 0, they were higher only in T1 and T2 in Group 6., Conclusion: We determined that it would be appropriate to prefer 3 L/min supplemental oxygen therapy with NC in C/S to be performed under SA., (© 2024.

Background and objectives : The frontal QRS-T angle is a novel parameter of myocardial repolarization. Weight gain during pregnancy and physiological changes during a cesarian section may affect the frontal QRS-T angle. We aimed to assess the effect of body mass index (BMI) on the frontal QRS-T angle in pregnant women undergoing cesarean section with spinal anesthesia. Method and materials : This study included 90 pregnant women. BMI was calculated for all pregnant women. The study population was divided into two groups: BMI < 30 (n = 66) and BMI ≥ 30 (n = 24). QT interval measurements and the frontal QRS-T angle were obtained from the report of an electrocardiography machine. Results : It was found that the pre-operative and post-operative frontal QRS-T angle ( p = 0.045 and p = 0.007) and QTc interval ( p = 0.037 and p < 0.001) were higher in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. In addition, when compared to pre-operative values, the post-operative frontal QRS-T angle (from 24.0 [20.0-41.5] to 34.5 [19.5-50.0], p = 0.031) and QTc interval (from 420.6 ± 13.3 to 431.7 ± 18.3, p = 0.010) were increased in the BMI ≥ 30 group, whereas no significant post-operative increase was observed in the BMI < 30 group. In correlation analysis, BMI was positively correlated with the frontal QRS-T angle and QTc interval. Conclusions : The frontal QRS-T angle and QTc interval were importantly increased in pregnant women with a BMI ≥ 30 than in pregnant women with a BMI < 30. Also, after cesarean section operation with spinal anesthesia, the frontal QRS-T angle and QTc were increased significantly in the BMI ≥ 30 group, whereas no significant change was observed in the BMI < 30 group. Therefore, it is suggested to perform close post-operative monitoring in pregnant women with a BMI ≥ 30 undergoing cesarean section with spinal anesthesia.

Background: Cesarean deliveries (CD) are commonly performed using neuraxial anesthesia. The use of neuraxial morphine has proven beneficial in terms of postoperative pain management; however, its effect on postoperative urine retention remains unclear., Objectives: To determine whether morphine injection into the neuraxis during CD influences postoperative urinary retention rate., Methods: We conducted a retrospective case-control observational study of patients undergoing CD. We compared patients using morphine injected into the intrathecal or epidural spaces (November 2020 to October 2021) to a historical cohort of patients undergoing CD without morphine (November 2019 to October 2020). The primary outcome was the rate of postoperative overt urinary retention necessitating bladder catheterization., Results: The study group comprised 283 patients, and 313 patients in the control group were eligible for analysis. No differences were found with respect to the baseline demographic and indication for CD. The number of postpartum urinary bladder catheterizations due to urine retention was higher in the study group (5% vs. 1%, P-value = 0.003). No cases of 30-day readmission were recorded. Moreover, patients treated with neuraxial morphine required fewer repeat doses of postoperative anesthesia (oral analgesia 7.4 vs. 10.1, intravenous analgesia 0.29 vs. 0.31, oral opioids 0.06 vs. 3.70, intravenous opioids 0.01 vs. 0.45, P-value < 0.001 for all)., Conclusions: While neuraxial morphine used during CD appears to be safe and effective, the risk of postoperative urinary retention seems to be increased due to its use. Cases of overt urinary retention treated by bladder catheterization does not lead to short-term complications.

Objective: Second-stage cesarean delivery (CD) is associated with subsequent preterm birth (PTB). It has been suggested that an increased risk of PTB after second-stage cesarean delivery could be linked to a higher chance of cervical injury due to the extension of the uterine incision. Previous studies have shown that reverse breech extraction is associated with lower rates of uterine incision extensions compared to the "push" method. We aimed to investigate the association between the method of fetal extraction during second-stage CD and the rate of spontaneous PTB (sPTB), as well as other maternal and neonatal outcomes during the subsequent pregnancy., Methods: This was a multicenter retrospective cohort study. The study population included women in their first subsequent singleton delivery following a second-stage CD between 2004 and 2021. The main exposure of interest was the method of fetal extraction in the index CD ("push" method vs. reverse breech extraction). The primary outcome of this study was sPTB <37 weeks in the subsequent pregnancy. Secondary outcomes were overall PTB, trial of labor, and other adverse maternal and neonatal outcomes. Univariate analysis was followed by multiple logistic regression modeling., Results: During the study period, 2969 index CD during second stage were performed, of those 583 met the inclusion criteria, of whom 234 (40.1%) had fetal extraction using the reverse breech extraction method, while 349 (59.9%) had the "push" method for extraction. In univariate analysis, women in those two groups had statistically similar rates of sPTB (3.7% vs. 3.0%; odds ratio [OR] 1.25, 95% CI: 0.49-3.19) and overall PTB (<37, <34 and <32 weeks), as well as other maternal, neonatal, and trial of labor outcomes. This was confirmed by multivariate analyses with an adjusted OR of 1.27 (95% CI: 0.43-3.71) for sPTB., Conclusion: Among women with a previous second-stage CD, no significant difference was observed in PTB rates in the subsequent pregnancies following the "push" method compared to the reverse breech extraction method., (© 2024 The Authors.

Background: Induction of labor (IOL) is recommended following prelabor rupture of membranes (PROM). The optimal method for IOL and need for cervical ripening in those with PROM and an unfavorable cervical examination is unclear., Objective: To determine if oxytocin or oral misoprostol results in a shorter time to delivery among nulliparous patients with an unfavorable cervical examination and PROM diagnosis and to evaluate patient satisfaction with both methods., Study Design: This is a randomized clinical trial conducted at an urban tertiary care center from 2019 to 2023. Subjects were nulliparas ≥36 weeks with an unfavorable starting cervical exam (≤2 cm and Bishop <8). The primary outcome was time from IOL to delivery in hours compared between oxytocin vs oral misoprostol. Secondary outcomes included suspected intraamniotic infection, cesarean delivery, composite maternal and neonatal morbidity, and patient satisfaction (assessed by Birth Satisfaction Scale-Revised). Sub-group analyses for those with BMI ≥ 30 kg/m 2 and cervical dilation ≥1 cm were performed. We required 148 subjects to have 80% power to detect a 2-hour difference in time to delivery. The study was stopped early by the data safety monitoring board due to feasibility concerns in recruiting desired sample size., Results: A total of 108 subjects were randomized: 56 oxytocin; 52 oral miso. The median gestational age at induction was 39.5 weeks; the mean starting cervical dilation was 1.1 cm. There was no statistical difference in time to delivery between groups overall: 14.9 hours oxytocin vs 18.1 hours oral misoprostol (P=.06). In sub-group analyses, there was a 5 hours shorter time to delivery with oxytocin for those with a BMI ≥ 30 kg/m 2 (16.6 hours oxytocin vs 21.8 hours oral misoprostol, P .04) and 4.5 hours shorter time to delivery with oxytocin for those with cervix ≥1 cm (12.9 hours oxytocin vs 17.3 hours oral misoprostol, P .04). There were no differences in intraamniotic infection, cesarean delivery, maternal or neonatal morbidity between the groups. Patient satisfaction was higher for those receiving oxytocin compared to misoprostol (29.0 vs 26.3, P=.03)., Conclusion: Among nulliparas with PROM and an unfavorable cervix, there was no difference in overall time to delivery between oxytocin and oral misoprostol. This result should be interpreted with caution given early study discontinuation and inadequate power. However, a shorter time to delivery with oxytocin was noted in obese patients and those with cervical dilation of at least 1 cm. Furthermore, patient satisfaction was higher in the oxytocin group, and there was no increased risk of neonatal or maternal morbidity with oxytocin., (Copyright © 2024 Elsevier Inc.

Objectives: Parturients are at increased risk for difficult airway management with subsequent fetal complications. Videolaryngoscopy was opined to be the new standard of airway care to facilitate orotracheal intubation under urgent care conditions. We examined in parturients requiring general anesthesia for urgent cesarean delivery the association of the type of laryngoscopy technique and time required to facilitate orotracheal intubation with the incidence of subsequent neonatal intensive care unit (NICU) admission., Methods: Following institutional review board approval, 431 parturients aged 18 years and older who underwent urgent cesarean section requiring general anesthesia were entered into this study. Patient characteristics, maternal comorbidities, and indications for urgent cesarean delivery were collected from the electronic medical records from January 2013 to November 2018. Orotracheal intubation times by type of laryngoscopy (video or direct) and NICU admission rates also were collected. A measure of effect size, risk differences with 95% confidence intervals (CIs), were calculated for the likelihood of NICU admission by difficult orotracheal intubation and by type of laryngoscopy used to secure the airway., Results: Videolaryngoscopy as the primary type of laryngoscopy was used in 24.1% (95% CI 20.3%-28.3%) of general anesthetics. The incidence of difficult orotracheal intubation was 4.4% (95% CI 2.8%-6.7%), with a higher incidence observed with videolaryngoscopy (8.7%) than with direct laryngoscopy (3.1%) and a risk difference of 5.6% (95% CI 0.001%-11.3%). The incidence of NICU admission was 38.4% (95% CI 34.0%-43.1%). Times for successful orotracheal intubation were longer with videolaryngoscopy. Videolaryngoscopy had a higher association for NICU admission (47%) than for direct laryngoscopy (36%), with a risk difference of 11.4% (95% CI 0.01%-22.3%)., Conclusions: Videolaryngoscopy did not decrease the incidence of difficult orotracheal intubation, and it did not decrease the time associated with orotracheal intubation. Videolaryngoscopy was associated with a higher association of NICU admission. These results suggest that videolaryngoscopy does not supplant direct laryngoscopy as the standard of care for orotracheal intubation under urgent care conditions of general anesthesia for cesarean section.

Objectives: To systematically review randomized controlled trials (RCTs) and perform a meta-analysis comparing early amniotomy with delayed amniotomy in individuals undergoing pre-induction cervical ripening by Foley balloon. The primary outcome was the rate of cesarean delivery. Understanding the impact of the timing of amniotomy on the rate of cesarean delivery is crucial for obstetricians and healthcare providers when making decisions about the management of labor induction., Data Sources: Data were sourced from electronic databases, including PubMed, OVID, Cochrane Library, Web of Science, and ClinicalTrials.gov through February 2024. The review adhered to Preferred Reporting Item for Systematic Reviews guidelines and registered with PROSPERO (ID CRD42023454520)., Study Eligibility Criteria: Inclusion criteria comprised RCTs comparing early amniotomy with delayed amniotomy in individuals undergoing cervical ripening by Foley balloon. Early amniotomy was defined as amniotomy soon after cervical ripening. Delayed amniotomy was defined as withholding amniotomy until after the onset of the active phase of labor, until at least 4 hours from either initiation of oxytocin or Foley balloon removal/expulsion, or until achieving >4 cm of dilation. Participants included nulliparous or multiparous individuals with singleton pregnancies undergoing labor induction at 37 weeks or later., Study Appraisal and Synthesis: A systematic literature search was conducted using defined search terms including "early amniotomy," "delayed amniotomy," "induction of labor," "cervical ripening," and "Foley balloon," and "Foley catheter." The quality of the included trials was assessed using the Cochrane Risk of Bias Tool for randomized controlled trials. The primary outcome was cesarean delivery. Secondary outcomes included outcomes related to labor duration and neonatal outcomes. Pooled relative risks (RR) and weighted mean differences (WMD) with 95% confidence intervals were calculated., Results: Five trials involving 849 participants undergoing induction and cervical ripening by Foley balloon were included. The rate of cesarean delivery did not differ between individuals randomly assigned to the early amniotomy group compared with those assigned to the delayed amniotomy group (22.9% vs. 23.3%; RR 1.00; 95% CI 0.65-1.55). Early amniotomy compared to delayed amniotomy was associated with a higher proportion of delivery within 24 hours (79.9% vs. 67.1%; RR 1.19; 95% CI 1.04-1.36). Early amniotomy compared with delayed amniotomy was associated with a shorter interval from oxytocin to delivery (WMD -1.5 hours; 95% CI -2.1 to -0.8), from Foley expulsion to vaginal delivery (WMD -2.5 hours; 95% CI -4.8 to -0.1), and from the start of oxytocin to vaginal delivery (WMD -1.8 hours; 95% CI -3.2 to -0.4). Other outcomes were not significantly different., Conclusion: Early amniotomy following cervical ripening by Foley balloon in individuals with singleton pregnancies did not impact rates of cesarean delivery compared with delayed amniotomy but led to shorter duration for various labor progress outcomes., (Copyright © 2024 Elsevier Inc.

Background: Cricoid pressure has been surrounded with controversies regarding its effectiveness. Application of ultrasound-guided para-laryngeal (PL) force has been shown to occlude the esophagus effectively compared with cricoid pressure (CP) in awake patients. We hypothesized that there would be no meaningful difference in the change in antero-posterior esophageal diameter from with application of cricoid or para-laryngeal pressure in parturients undergoing cesarean delivery under general anesthesia., Methods: In this prospective, randomized, non-inferiority trial, 40 parturients scheduled for elective cesarean delivery under general anesthesia were randomized to receive rapid sequence induction with either cricoid pressure (n = 20) or para-laryngeal pressure (n = 20). The antero-posterior diameter of the esophagus, measured by sonography, was the primary outcome. Visualization of the esophagus, its position in relation to the glottic aperture, esophageal occlusion, percentage of glottic opening (POGO), time to intubation, first pass success rate, overall success rate and adverse events like desaturation or bronchospasm were secondary outcomes., Results: The mean change in anterior-posterior diameter in the CP group was 0.17 ±0.1 cm vs. 0.28 ±0.1 cm in the PL group. The mean difference (CP-para-laryngeal pressure) between the groups was -0.11 (95% CI -0.17 to -0.1) cm. As the upper limit of the 95% CI was lower than the prespecified non-inferiority margin (δ = -0.2), non-inferiority was established (P <0.001]. There was no significant difference in the POGO score (P = 0.818), time to intubation (P =0.55), or intubation attempts (P = 0.99)., Conclusions: Para-laryngeal pressure was non-inferior to CP in occluding the esophagus in parturients undergoing cesarean delivery under general anesthesia and furthermore, no significant deterioration in intubation parameters was seen., (Copyright © 2024 Elsevier Ltd.

Objective: To compare the efficacy of foot reflexology and Benson's relaxation on anxiety and physiologic parameters after cesarean surgery., Design: Randomized controlled trial with three parallel arms., Setting: Gynecologic ward of the Persian Gulf Martyrs Hospital in Bushehr, Iran, in 2020., Participants and Interventions: Women undergoing cesarean surgery (n = 135) were selected by convenience sampling and divided via block randomization into three groups of foot reflexology, Benson's relaxation interventions, and control group (n = 45 in each group). Interventions were performed 2 hours after cesarean surgery., Measurements: Spielberger's State-Trait Anxiety Inventory, mercury sphygmomanometer, and pulse oximeter were used to collect the data. Anxiety was measured before and 30 minutes after the intervention. Physiologic parameters were measured before the intervention and immediately, 30 minutes, and 60 minutes after the intervention. Data were analyzed using inferential statistics., Results: The mean score of situational anxiety after the intervention was significantly lower than before the intervention in the reflexology (t = 6.171; 95% confidence interval [CI] [5.66, 11.14]) and Benson's relaxation groups (t = 7.362; 95% CI [5.91, 9.85]). However, changes in the control group were not significant (t = 1.674; 95% CI [-0.24, 2.55]). Decreases in anxiety scores were similar in the two intervention groups. After intervention, in most measurement times, respiratory rate and pulse rate decreased in the two intervention groups compared to the control group, and arterial oxygen saturation and systolic blood pressure increased., Conclusion: Considering the effect of both interventions on decreasing anxiety and improving most physiologic parameters, it seems that foot reflexology and Benson's relaxation can be recommended after cesarean surgery., (Copyright © 2024 AWHONN.

Objective: Cesarean scar pregnancy may lead to varying degrees of complications. There are many treatment methods for it, but there are no unified or recognized treatment strategies. This systematic review and network meta-analysis aimed to observe the efficacy and safety of treatment modalities for patients with cesarean scar pregnancy., Data Sources: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were searched from their inception to January 31, 2024. In addition, relevant reviews and meta-analyses were manually searched for additional references., Study Eligibility Criteria: Our study incorporated head-to-head trials involving a minimum of 10 women diagnosed with cesarean scar pregnancy through ultrasound imaging or magnetic resonance imaging, encompassing a detailed depiction of primary interventions and any supplementary measures. Trials with a Newcastle-Ottawa scale score <4 were excluded because of their low quality., Methods: We conducted a random-effects network meta-analysis and review for cesarean scar pregnancy. Group-level data on treatment efficacy and safety, reproductive outcomes, study design, and demographic characteristics were extracted following a predefined protocol. The quality of studies was assessed using the Cochrane risk-of-bias tools for randomized controlled trials and the Newcastle‒Ottawa scale for cohort studies and case series. The main outcomes were efficacy (initial treatment success) and safety (complications), of which summary odds ratios and the surface under the cumulative ranking curve using pairwise and network meta-analysis with random effects., Results: Seventy-three trials (7 randomized controlled trials) assessing a total of 8369 women and 17 treatment modalities were included. Network meta-analyses were rooted in data from 73 trials that reported success rates and 55 trials that reported complications. The findings indicate that laparoscopy, transvaginal resection, hysteroscopic curettage, and high-intensity focused ultrasound combined with suction curettage demonstrated the highest cure rates, as evidenced by surface under the cumulative ranking curve rankings of 91.2, 88.2, 86.9, and 75.3, respectively. When compared with suction curettage, the odds ratios (95% confidence intervals) for efficacy were as follows: 6.76 (1.99-23.01) for laparoscopy, 5.92 (1.47-23.78) for transvaginal resection, 5.00 (1.99-23.78) for hysteroscopic curettage, and 3.27 (1.08-9.89) for high-intensity focused ultrasound combined with suction curettage. Complications were more likely to occur after receiving uterine artery chemoembolization, suction curettage, methotrexate+hysteroscopic curettage, and systemic methotrexate; hysteroscopic curettage, high-intensity focused ultrasound combined with suction curettage, and Lap were safer than the other options derived from finite evidence; and the confidence intervals of all the data were wide., Conclusion: Our findings indicate that laparoscopy, transvaginal resection, hysteroscopic curettage, and high-intensity focused ultrasound combined with suction curettage procedures exhibit superior efficacy with reduced complications. The utilization of methotrexate (both locally guided injection and systemic administration) as a standalone medical treatment is not recommended., (Copyright © 2024 The Author(s).

As the number of placenta accreta spectrum cases continues to rise, the gap in surgical skills in labor and delivery units becomes more apparent. Recent scholarly work has highlighted the diminishing advanced surgical skills among obstetrician-gynecologists, particularly among new graduates. Therefore, it has become a practice in many institutions to refer complex cesarean deliveries and obstetrical hysterectomies to subspecialists, specifically gynecologic oncologists. Hence, in this commentary, we propose a process through which key personnel within departments of obstetrics and gynecology are identified and their appropriate level of involvement in cases of complex obstetrical surgery is delineated. In doing so, we describe the surgical skills expected from each provider level so that the cesarean delivery complexity level can be matched with specific surgical expertise. Through this process, an obstetrician-led complex obstetrical surgery team is formed. Ultimately, the goal of this process is 2-fold; first, to return cases with higher levels of surgical complexity back to obstetricians and, second, to reduce the surgical back-up burden from gynecology subspecialists such as gynecologic oncologists., (Copyright © 2024 Elsevier Inc.

Background: Improved pain control after cesarean section remains a challenging objective. Although both the lateral quadratus lumborum block (L-QLB) and acupuncture have been reported to provide superior postoperative analgesia after cesarean section when compared to placebo, the efficacy of these techniques has never been compared head-to-head., Objective: This study was conducted to investigate the comparative analgesic efficacy of L-QLB and acupuncture following elective cesarean section., Study Design: In this prospective, randomized, controlled clinical trial, a total of 190 patients with singleton-term pregnancies scheduled for cesarean section under spinal-epidural anesthesia were enrolled. Patients were randomized 1:1 to acupuncture group or L-QLB group. L-QLB group received bilateral L-QLB with 0.33% ropivacaine and sham acupuncture, acupuncture group received transcutaneous electrical acupoint stimulation and press needle therapy, and sham L-QLB. All patients received the standard postoperative pain treatment. The primary outcome was pain scores on movement at 24 hours. Secondary endpoints included pain scores in the first 48 hours postoperatively, patient-controlled intravenous analgesia (PCIA) demands, analgesia-related adverse effects, postoperative complications, QoR-15, the time to mobilization, and gastrointestinal function., Results: Median (interquartile range [range]) pain scores at 24 hours on movement were similar in patients receiving acupuncture or L-QLB (3 [2-4] vs 3 [2-4], respectively; P=.40). PCIA consumption and pain scores within 48 hours postoperatively also showed no difference between the two groups. The acupuncture improved QoR-15 scores at 24 and 48 hours postoperatively (P<.001), as well as shortened the time to first flatus (P=.03) and first drinking (P<.001) compared to L-QLB. In addition, the median time to mobilization in the L-QLB group was markedly prolonged compare with acupuncture group (17.0 [15.0-19.0] hours vs 15.3 [13.3-17.0] hours, estimated median difference, 1.5; 95% CI, 1-2; P<.001)., Conclusion: As a component of multimodal analgesia regimen after cesarean section, acupuncture did not lower postoperative pain scores or reduce analgesic medication consumption compared to L-QLB., (Copyright © 2024 Elsevier Inc.

Background: The global prevalence of caesarean section as a delivery method is increasing worldwide. However, there is notable divergence among countries in their national guidelines regarding the optimal technique for blunt expansion hysterotomy of the low transverse uterine incision during caesarean section (cephalad-caudad or transverse)., Aim: To compare the risk of severe postpartum haemorrhage (PPH) between cephalad-caudad and transverse blunt expansion hysterotomy during caesarean section., Methods: This prospective comparative observational study was conducted in a university maternity hospital. All women who gave birth to one infant by caesarean section after 30 weeks of gestation between November 2020 and November 2021 were included in this study. The exclusion criteria were a coagulation disorder, the presence of placenta previa, multiple pregnancies, or enlargement of the hysterotomy with scissors. The choice between cephalad-caudad or transverse blunt expansion of the low transverse hysterotomy was left to the surgeon's discretion. The primary outcome measure was severe PPH, defined as estimated blood loss ≥ 1000 ml. Univariate and multivariate analyses were employed to assess the risk of severe PPH associated with the two methods of enlarging the low transverse hysterotomy., Results: The study included 850 women, of whom 404 underwent transverse blunt expansion and 446 underwent cephalad-caudad blunt expansion. The overall incidence of severe PPH was 13.3 %. Univariate analysis revealed no significant difference in the frequency of severe PPH between the cephalad-caudad and transverse blunt expansion groups (13.9 % vs 12.6 %; p = 0.61). However, the use of additional surgical sutures (mainly additional haemostatic stitches) was less common with cephalad-caudad blunt expansion (26.7 % vs 36.9 %; p < 0.05). Multivariate analysis showed no significant difference in risk between the two techniques (odds ratio 1.17, 95 % confidence interval 0.77-1.78)., Conclusion: No significant difference in the risk of severe PPH was found between cephalad-caudad and transverse blunt expansion of the low transverse hysterotomy during caesarean section., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: The hemodynamic effects of relatively low-dose epinephrine and phenylephrine infusions during cesarean delivery under spinal anesthesia were compared., Methods: This randomized controlled trial included full-term pregnant women who underwent elective cesarean delivery. After spinal anesthesia, participants received either epinephrine (0.03 mcg/kg/min) or phenylephrine (0.4 mcg/kg/min) infusion that continued until 5 min after delivery. The primary outcome was a composite outcome of the occurrence of any of hypotension, hypertension, bradycardia, and/or tachycardia. Neonatal outcomes, including umbilical artery blood gas and Apgar scores, were assessed., Results: In total, 98 patients in each group were analyzed, and the number of patients with the composite outcome was comparable between the epinephrine and phenylephrine groups (30/98 [31%] vs. 31/98 [32%], respectively; P = 0.877). However, the incidence of hypotension was likely lower in the epinephrine group than in the phenylephrine group (P = 0.066), and the number of hypotensive episodes per patient was lower in the epinephrine group than in the phenylephrine group. On the other hand, the incidence of tachycardia was higher in the epinephrine group than that in the phenylephrine group. The incidence of hypertension was comparable between the two groups and none of the participants developed bradycardia. Neonatal outcomes were comparable between the two groups., Conclusions: Epinephrine and phenylephrine infusion produced comparable maternal hemodynamics and neonatal outcomes. Epinephrine was associated with a higher incidence of maternal tachycardia and likely lower incidence of maternal hypotension than phenylephrine.

Purpose: To elucidate the clinical impact of the novel oxytocin protocol using a syringe pump with a stratified dose compared with the conventional practice of putting oxytocin into the bag., Methods: This is a retrospective cohort study. We collected the data of the patients who underwent elective cesarean delivery under neuraxial anesthesia between June 2019 and May 2020. The patients were allocated to two groups according to oxytocin administration methods; the control group (the attending anesthesiologist put oxytocin 5-10 units in the infusion bag and adjusted manually after childbirth) and the protocol group (the oxytocin protocol gave oxytocin bolus 1 or 3 units depending on the PPH risk, followed by 5 or 10 unit h -1 via a syringe pump). We compared the total amount of oxytocin within 24 h postpartum, estimated blood loss, and adverse clinical events within 24 h postpartum between the two groups., Results: During the study period, 262 parturients were included. Oxytocin doses of intraoperative and postoperative were significantly lower in the protocol group (9.7 vs. 11.7 units, intraoperative, 15.9 vs. 18 units, postoperative). The subgroup analyses showed that the impact was more remarkable in the low PPH risk than in the high PPH risk. The multivariate linear regression analyses also confirmed the difference. The groups had no significant difference in blood loss, requirement of additional uterotonics, and other adverse events., Conclusions: Our oxytocin infusion protocol significantly reduced oxytocin requirements in elective cesarean delivery under neuraxial anesthesia without increasing blood loss. However, we could not find other clinical benefits of the novel protocol., (© 2024. The Author(s).)

Case Presentation: A 35-year-old woman at 36 weeks and 4 days gestation with known complete anterior placenta previa and no other medical history presented for routine obstetric follow-up. She reported increasing fatigue in the prior week but otherwise endorsed no new concerns. She denied recent vaginal bleeding or discharge, abdominal pain, contractions, or extremity swelling. On evaluation, her BP was 126/74 mm Hg with a heart rate of 72 beats per min. The results from the physical examination were normal. There was a category II fetal heart rate tracing and a 6/10 biophysical profile (ie, no fetal breathing movements, nonreactive nonstress test), which prompted referral to the hospital. On admission, sonogram confirmed cephalic presentation and redemonstrated complete anterior placenta previa with no evidence of hemorrhage. She received antenatal steroids and was scheduled for a cesarean section delivery. She received bupivacaine spinal anesthesia for the procedure. The surgical procedure progressed with a low transverse uterine incision and subsequent delivery of the baby with no complications noted. Immediately after delivery of the baby and during gentle traction of the placenta, the patient experienced rapid cardiovascular collapse in the form of hypotension and bradycardia., Competing Interests: Financial/Nonfinancial Disclosures None declared., (Copyright © 2024 American College of Chest Physicians.

Background: Cesarean delivery (CD) is one of the most common surgeries performed worldwide, with increasing yearly rates. Although neuraxial techniques remain the preferred anesthesia method for CD, maternal thrombocytopenia remains a prominent contraindication. Formation of spinal\epidural hematomas are extremely rare, however the minimal thrombocyte count required for safe neuraxial anesthesia is still under debate. Although transfusion of thrombocytes for the purpose of neuraxial anesthesia is still not recommended, patients with severe thrombocytopenia (less than 50 × 103/uL) are given thrombocyte transfusion for surgical hemostasis., Objectives: To evaluate the anesthetic approach to caesarean deliveries in parturients with severe thrombocytopenia who received thrombocyte transfusion aimed for improved surgical hemostasis., Methods: We conducted a single center, retrospective cohort study. Results: A total of five cases were found, four of which were given spinal anesthesia immediately following thrombocyte transfusion. One patient was denied spinal anesthesia because her thrombocyte count following transfusion failed to reach safe levels. None of our cases had anesthesia-related complications recorded., Conclusions: We examined the anesthetic management parturients with severe thrombocytopenia who needed cesarean delivery and were transfused with thrombocytes for surgical hemostasis. In such cases, spinal anesthesia may be considered due to the serious risks associated with general anesthesia.

A G4P4 woman in her 30s with a type II vesicouterine fistula, as defined by the Jozwik classification system, presented with symptoms of menouria, vaginal menses and urinary incontinence 8 years after caesarean delivery, the time of probable origination of the fistula tract. Transvaginal ultrasound identified a fistula tract communicating between the bladder and uterus, a rare finding that many years remote from caesarean delivery. Traditional surgical technique includes laparoscopic, abdominal and endoscopic methods of repair, sometimes using a transvesical approach. Transvesical repair can be associated with subsequent inpatient hospital stays and prolonged catheterisation. Our technique proposes a transvaginal surgical approach as an outpatient procedure with decreased operating time (40 min), postoperative pain and catheterisation requirement. It is the authors' belief that a transvaginal approach is less invasive and allows for better preservation of the uterus for future pregnancies and vaginal deliveries, as desired by the patient., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: We compared Pfannenstiel and midline skin incisions for cesarean hysterectomy in women with confirmed Placenta Accreta Spectrum Disorders. Aims: A retrospective cohort study was conducted to evaluate the outcomes of Pfannenstiel and midline skin incisions in women undergoing cesarean section hysterectomy for suspected placenta accreta at Akdeniz University Hospital between January 2010 and February 2022. Histopathological confirmation was obtained for all cases. Demographic, perioperative, and postoperative data, along with neonatal outcomes, were extracted from the hospital's electronic database. Possible complaints related to the incision site or other issues (e.g., vaginal dryness or sexual life) were identified through telephone interviews. Subjects were stratified into Pfannenstiel and midline incision cohorts, with subsequent data comparison. Results: Data from 67 women with a histopathologically confirmed PAS diagnosis were analyzed. Of these, 49 (73.1%) underwent Pfannenstiel incision, and 18 (26.9%) had a midline skin incision. Incisions were based on the surgeon's experience. Pfannenstiel incision was more common in antepartum hemorrhage, preoperative hemorrhage, and emergency surgery ( p = 0.02, p = 0.014, p = 0.002, respectively). Hypogastric artery ligation occurred in 30 cases (61.2%) in the Pfannenstiel group but none in the midline group. Cosmetic dissatisfaction and sexual problems were more prevalent in the midline group ( p < 0.05, all). Preoperative and postoperative blood parameters, transfused blood products, and neonatal outcomes were similar between the two groups. Conclusions: Relaparotomy, bladder injury, blood loss, and need for blood transfusion were more prevalent in the Pfannenstiel group, while greater dissatisfaction with the incision was observed in the midline incision group. Midline incision seems to be more favorable in patients with Placenta Accreta Spectrum (PAS). Patients may be informed regarding the worse cosmetic outcomes and possible sexual problems related to vaginal dryness when midline laparotomy is planned. But before opting for a Pfannenstiel incision, patients should receive comprehensive information regarding the potential risks of relaparotomy and bladder injury.

Objective: To determine the prophylactic effect of hydrocolloid dressings on hypertrophic scarring in post-cesarean section wounds., Methods: Patients who underwent cesarean section (C/S) at the authors' hospital and provided informed consent to participate were randomly assigned to the intervention and control groups. The intervention group commenced applying hydrocolloid dressings to the wound on postoperative day 7 or 8 and continued with weekly dressing changes for 6 months. The control group refrained from any dressing application but was followed up. In each group, the condition of the wound was evaluated 6 and 12 months postoperatively using the Japan Scar Workshop Scar Scale 2015, the Patient and Observer Scar Assessment Scale version 2.0, the modified Vancouver Scar Scale, and patient-reported outcomes., Results: During this period, 135 patients underwent C/S at the authors' institution, and 47 (23 in the intervention group and 24 in the control group) were included in the analysis. In all assessment methods, the intervention group scored lower than the control group at 6 and 12 months after C/S. Twelve months after C/S, hypertrophic scarring (Japan Scar Workshop Scar Scale 2015 score of 6-15) was found in 14 of the 47 (29.8%) patients: 11 of 24 (45.8%) in the control group and 3 of 23 (13.0%) in the intervention group. The intervention's relative risk was 0.623 (95% CI, 0.417-0.930). The risk factor for hypertrophic scarring was midline vertical incision, with an odds ratio of 20.53 (95% CI, 4.18-100.92)., Conclusions: The study reveals that the application of hydrocolloid dressings to wounds reduces the risk of hypertrophic scarring after C/S., (Copyright © 2024 the Author(s).

A 32-year-old multigravida woman, with known familial hypokalaemic periodic paralysis, underwent spinal anaesthesia for an elective lower segment caesarean section. There are several case reports in the literature discussing the optimal anaesthetic technique. In the past there has not been an emphasis on aggressive and early potassium replacement. A target level to commence replacement of potassium at 4.0 mmol/L or less is proposed. Careful preoperative preparation, frequent perioperative monitoring and early potassium replacement resulted in no perioperative episodes of weakness in this case, in contrast with other case reports where potassium was either not monitored or not replaced early enough, resulting in postoperative attacks. Another factor to consider in hypokalaemic periodic paralysis is the avoidance of triggers, including certain medications. Misoprostol was used in this instance to avoid potential electrolyte derangements from other uterotonics., Competing Interests: Declaration of conflicting interestsThe authors declare no potential conflicts of interest with respect to the research, authorship and publication of this article.

Background: The resolution of factors linked to the recurrence of cesarean section defects can be accomplished through a comprehensive technique that effectively addresses the dehiscent area, eliminates associated intraluminal fibrosis, and establishes a vascularized anterior wall by creating a sliding myometrial flap., Objective: Propose a comprehensive surgical repair for recurrent and large low hysterotomy defects in women seeking pregnancy or recurrent spotting., Study Design: A retrospective cohort analysis included 54 patients aged 25-41 with recurrent large cesarean scar defects treated at Otamendi, CEMIC, and Valle de Lili hospitals. Comprehensive surgical repair was performed by suprapubic laparotomy, involving a wide opening of the vesicouterine space, removal of the dehiscent cesarean scar and all intrauterine abnormal fibrous tissues, using a glide myometrial flap, and intramyometrial injection of autologous platelet-rich plasma. Qualitative variables were determined, and descriptive statistics were employed to analyze the data in absolute frequencies or percentages. The data obtained were processed using the Infostat TM statistic program., Results: Following the repair, all women experienced normal menstrual cycles and demonstrated an adequate lower uterine segment thickness, with no evidence of healing defects. All patients experienced early ambulation and were discharged within 24 h. Uterine hemostasis was achieved at specific points, minimizing the use of electrocautery. The standard duration of the procedure was 60 min (skin-to-skin), and the average bleeding was 80-100 ml. No perioperative complications were recorded. A control T2-weighted MRI was performed six months after surgery. All patients displayed a clean, unobstructed endometrial cavity with a thick anterior wall (Median: 14.98 mm, IQR 13-17). Twelve patients became pregnant again, all delivered by cesarean between 36.1 and 38.0 weeks, with a mean of 37.17 weeks. The thickness of the uterine segment before cesarean ranged between 3 and 7 mm, with a mean of 3.91 mm. No cases of placenta previa, dehiscence, placenta accreta spectrum (PAS), or postpartum hemorrhage were reported., Conclusions: The comprehensive repair of recurrent low-large defects offers a holistic solution for addressing recurrent hysterotomy defects. Innovative repair concepts effectively address the wound defect and associated fibrosis, ensuring an appropriate myometrial thickness through a gliding myometrial flap.

Objective: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients., Study Design: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m 2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ 2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively., Results: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, β = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time., Conclusion: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.

Objective: The purpose of this study was to determine the factors that influence physician preference for type of hysterotomy incisions in gravidas with a singleton or twin pregnancy undergoing cesarean section under 28 weeks, and to assess factors that result in delivery complications, defined as either intraoperative dystocia or hysterotomy extension. We hypothesized that compared to those with non-cephalic presentations, gravidas with a presenting fetus in cephalic presentation would have higher rates of low-transverse cesarean section, and reduced rates of delivery complications with low-transverse hysterotomy., Methods: This was a retrospective cohort chart analysis of 128 gravidas between 23 0/7 and 27 6/7 weeks undergoing cesarean section at a single academic institution between August 2010 and December 2022. Data was abstracted for factors that might influence the decision for hysterotomy incision type, as well as for documentation of difficulty with delivery of the fetus or need for hysterotomy extension to affect delivery., Results: There was a total of 128 subjects, 113 with a singleton gestation and 15 with twins. The presenting fetus was in cephalic presentation in 43 (33.6%), breech presentation in 71 (55.5%), transverse/oblique lie in 13 (10.2%), and not documented in 1 (0.8%). Sixty-eight (53.1%) had a low-transverse cesarean section (LTCS), 53 (41.4%) had a Classical, 5 (3.9%) had a low-vertical hysterotomy and 2 (1.6%) had a mid-transverse incision. There was a significantly higher rate of LTCS among gravidas with the presenting fetus in cephalic presentation (30/43, 69.8%) compared to those with breech (31/71, 43.7%) or transverse/oblique presentations (7/13, 53.8%), p = .03. No other significant associations were related to hysterotomy incision, including nulliparity, racially or ethnically minoritized status, plurality, indication for cesarean delivery, or pre-cesarean labor. Twenty (15.6%) subjects experienced either an intraoperative dystocia or hysterotomy extension. For the entire cohort, there was a greater median cervical dilatation in those with delivery complications (4.0 cm, IQR .5 - 10 cm) compared to those without complications (1.5, IQR 0 - 4.0), p = .03, but no significant association between delivery complications and fetal presentation, hysterotomy type, plurality, or other demographic/obstetrical factors. However, among gravidas undergoing low-transverse cesarean section, only 2/30 (6.7%) with cephalic presentations had a delivery complication, compared to 9/31 (29.0%) with breech presentations and 3/7 (42.9%) with a transverse/oblique lie, p = .03., Conclusion: In pregnancies under 28 weeks, the performance of a low-transverse cesarean section was significantly associated only with presentation of the presenting fetus. Among those with cephalic presentations, the rate of intrapartum dystocia or hysterotomy extension was low after a low-transverse hysterotomy, suggesting that in this subgroup, a low-transverse cesarean section should be considered.

Introduction: It is still no consensus on the use of ropivacaine or bupivacaine in epidural anesthesia for cesarean section (CS), because their anesthetic potency and relative complications remains controversial. This system review and meta-analysis aimed to compare the efficacy of epidural ropivacaine and bupivacaine for elective CSs and investigate relative complications for parturients and neonates., Methods: We searched PubMed, MEDLINE, Embase, Cochrane Library, Science-Direct, and Google Scholar to June 30, 2023 for randomized controlled trials (RCTs), which compared epidural ropivacaine with bupivacaine for elective CSs. The success rate of epidural anesthesia (EA) was primary outcome. The secondary outcomes included onset times of sensory block, maternal side effects, neonatal Apgar scores and umbilical artery pH., Results: We analyzed 8 RCTs with 532 parturients. 0.75% ropivacaine is associated with a shorter onset time of sensory block than 0.5% bupivacaine (SMD = -0.43, 95% CI: -0.70 to -0.17; p  = .001). 0.5% ropivacaine resulted in a reduced nausea than 0.5% bupivacaine (RR = 0.49, 95% CI: 0.28 to 0.83; p  = .008). In addition, there were no significant difference between ropivacaine and bupivacaine groups in terms of success rate of epidural anesthesia, maternal side effects (hypotension, bradycardia, shivering), and neonatal Apgar scores and umbilical artery pH., Conclusions: The findings suggest that there were no significant difference between epidural ropivacaine and bupivacaine for elective CSs in terms of the success rate (85.9% vs. 83.5), maternal side effects (hypotension, bradycardia, shivering), and neonatal Apgar scores and umbilical artery pH. But compared with 0.5% bupivacaine, epidural 0.75% ropivacaine was mildly effective for reducing onset time of sensory block and 0.5% ropivacaine reduced the incidence of maternal nausea.

Background: Caesarean section is a widely performed surgical procedure that often results in moderate-to-severe postoperative pain. If left untreated, this pain can lead to short-term and long-term consequences. Transversalis fascia plane (TFP) block and transversus abdominis plane (TAP) block are among the regional anaesthesia techniques employed for managing pain after a caesarean section., Objective: We aimed to compare the impact of these two blocks on the quality of recovery in patients undergoing elective caesarean section under spinal anaesthesia., Design: A single-centre, double-blind, randomised trial., Settings: Operating room, postanaesthesia recovery unit, and ward in a tertiary hospital., Participants: Ninety-three patients (ASA 2 to 3) were recruited. After exclusion, 79 patients were included in the final analysis: 40 in the TFP block group and 39 in the TAP block group., Interventions: After surgery, participants received either TFP block (20 ml 0.25% bupivacaine for each side) or TAP block (20 ml 0.25% bupivacaine for each side)., Main Outcome Measures: The primary outcome was the difference in obstetric quality of recovery 11-Turkish (ObsQoR-11T) scores between groups. Secondary outcomes included pain scores, opioid consumption and incidence of opioid-related complications., Results: The mean ObsQoR-11T score was higher in the TFP block group compared with the TAP block group (97.13 ± 6.67 points vs. 87.10 ± 9.84 points, respectively; P  < 0.001). The pain scores in the TFP block group were slightly lower between postoperative 4 and 24 h. The mean total morphine consumption was 15.08 ± 2.21 mg in the TFP block group and 22.21 ± 3.04 mg in the TAP block group ( P  < 0.001). More patients required rescue analgesia between 4 and 8 h in the TAP block group [2.00 (5.00%) vs. 9.00 (23.08%), P  = 0.02]. No significant differences were observed between groups in terms of opioid-related side effects., Conclusion: TFP block used for analgesic purposes yielded a better quality recovery period than TAP block and also reduced opioid consumption., Trial Registration: Clinicaltrials.gov (NCT05999981)., Visual Abstract: http://links.lww.com/EJA/B6 ., (Copyright © 2024 European Society of Anaesthesiology and Intensive Care.

Objectives: To explore the obstetric, maternal and neonatal outcome in the subsequent pregnancy after a pregnancy with an accidental uterine extension (AUE) during cesarean delivery (CD), as well as the relationship between the different types of AUE (inferior, lateral and superior)., Methods: A retrospective cohort study of all CD with AUE in a tertiary medical center between 01/2011-01/2022. Women with a prior CD with AUE were compared to a 1:3 ratio matched control group of women with a prior CD without AUE. All AUE were defined in their direction, size and mode of suturing. CD with deliberate uterine extensions were excluded. We evaluated obstetric, maternal and neonatal outcomes in the subsequent pregnancy after a pregnancy with AUE during CD., Results: Comparing women with a prior CD with AUE (n=177) to the matched control group of women with a prior CD without AUE (n=528), we found no significant differences in proportions of uterine rupture or any other major complication or adverse outcome between the groups. There were no significant differences in the outcomes of the subsequent pregnancy in relation to the characteristics of the AUE (direction, size and mode of suturing)., Conclusions: Subsequent pregnancies after AUE are not associated with higher maternal or neonatal adverse outcomes including higher proportions of uterine rupture compared to pregnancies without previous AUE. Different characteristics of the AUE do not impact the outcome., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

Background: 3% chloroprocaine (CP) has been reported as the common local anesthetic used in pregnant women undergoing urgent cesarean delivery during labor analgesia period. However, 0.75% ropivacaine is considered a promising and effective alternative. Therefore, we conducted a randomized controlled trial to compare the effectiveness and safety of 0.75% ropivacaine with 3% chloroprocaine for extended epidural anesthesia in pregnant women., Methods: We conducted a double-blind, randomized, controlled, single-center study from November 1, 2022, to April 30, 2023. We selected forty-five pregnant women undergoing urgent cesarean delivery during labor analgesia period and randomized them to receive either 0.75% ropivacaine or 3% chloroprocaine in a 1:1 ratio. The primary outcome was the time to loss of cold sensation at the T4 level., Results: There was a significant difference between the two groups in the time to achieve loss of cold sensation (303, 95%CI 255 to 402 S vs. 372, 95%CI 297 to 630 S, p = 0.024). There was no significant difference the degree of motor block (p = 0.185) at the Th4 level. Fewer pregnant women required additional local anesthetics in the ropivacaine group compared to the chloroprocaine group (4.5% VS. 34.8%, p = 0.011). The ropivacaine group had lower intraoperative VAS scores (p = 0.023) and higher patient satisfaction scores (p = 0.040) than the chloroprocaine group. The incidence of intraoperative complications was similar between the two groups, and no serious complications were observed., Conclusions: Our study found that 0.75% ropivacaine was associated with less intraoperative pain treatment, higher patient satisfaction and reduced the onset time compared to 3% chloroprocaine in pregnant women undergoing urgent cesarean delivery during labor analgesia period. Therefore, 0.75% ropivacaine may be a suitable drug in pregnant women undergoing urgent cesarean delivery during labor analgesia period., Clinical Trial Number and Registry Url: The registration number: ChiCTR2200065201; http://www.chictr.org.cn , Principal investigator: MEN, Date of registration: 31/10/2022., (© 2024.

Introduction: Women of childbearing age make up around 5-10% of individuals with spinal cord injury (SCI) and may face unique medical and functional complications during pregnancy, including prolonged hospitalization and increased risk of early rehospitalization due to falls., Case Presentation: Here, we discuss a case of a young ambulatory woman with a lumbar motor incomplete spinal cord injury who underwent successful delivery via cesarean section and the role of the physiatrist in the management of the patient's antepartum, intrapartum, and postpartum complications. The patient faced significant antepartum challenges secondary to her neurogenic bladder and pelvic floor weakness, resulting in increased use of her manual wheelchair. The physiatry team assisted with the co-development of a multidisciplinary bladder plan for increased urinary frequency and urinary tract infection prevention with the patient's obstetrics physician (OB). In addition, the physiatry team assisted with the procurement of a new wheelchair suited for the patient's pregnancy and childcare needs in anticipation of decreased mobility during this time. Regarding intrapartum challenges, the physiatry team worked with the patient and her OB to develop a safe birth plan considering the method of delivery, epidural usage, and the need for pelvic floor therapy before and after childbirth., Discussion: The patient had a successful cesarean section delivery, with return to independent mobility soon after childbirth. In summary, this case demonstrates that there is a need for a multidisciplinary approach to patients with SCI during pregnancy and that the role of physiatry is critical to optimizing medical and functional outcomes., (© 2024.

Purpose: Adequate post-cesarean delivery analgesia can be difficult to achieve for women diagnosed with opioid use disorder receiving buprenorphine. We sought to determine if neuraxial clonidine administration is associated with decreased opioid consumption and pain scores following cesarean delivery in women receiving chronic buprenorphine therapy., Methods: This was a retrospective cohort study at a tertiary care teaching hospital of women undergoing cesarean delivery with or without neuraxial clonidine administration while receiving chronic buprenorphine. The primary outcome was opioid consumption (in morphine milligram equivalents) 0-6 h following cesarean delivery. Secondary outcomes included opioid consumption 0-24 h post-cesarean, median postoperative pain scores 0-24 h, and rates of intraoperative anesthetic supplementation. Multivariable analysis evaluating the adjusted effects of neuraxial clonidine on outcomes was conducted using linear regression, proportional odds model, and logistic regression separately., Results: 196 women met inclusion criteria, of which 145 (74%) received neuraxial clonidine while 51 (26%) did not. In univariate analysis, there was no significant difference in opioid consumption 0-6 h post-cesarean delivery between the clonidine (8 [IQR 0, 15]) and control (1 [IQR 0, 8]) groups (P = 0.14). After adjusting for potential confounders, there remained no significant association with neuraxial clonidine administration 0-6 h (Difference in means 2.77, 95% CI [- 0.89 to 6.44], P = 0.14) or 0-24 h (Difference in means 8.56, 95% CI [- 16.99 to 34.11], P = 0.51)., Conclusion: In parturients receiving chronic buprenorphine therapy at the time of cesarean delivery, neuraxial clonidine administration was not associated with decreased postoperative opioid consumption, median pain scores, or the need for intraoperative supplementation., (© 2024.

Objective: Counseling of pregnancies complicated by pre- and periviable premature rupture of membranes to reach shared decision-making is challenging, and the current limited evidence hampers the robustness of the information provided. This study aimed to elucidate the rate of obstetrical and neonatal outcomes after expectant management for premature rupture of membranes occurring before or at the limit of viability., Data Sources: Medline, Embase, CINAHL, and Web of Science databases were searched electronically up to September 2023., Study Eligibility Criteria: Our study included both prospective and retrospective studies of singleton pregnancies with premature rupture of membranes before and at the limit of viability (ie, occurring between 14 0/7 and 24 6/7 weeks of gestation)., Methods: Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale for cohort studies. Moreover, our study used meta-analyses of proportions to combine data and reported pooled proportions. Given the clinical heterogeneity, a random-effects model was used to compute the pooled data analyses. This study was registered with the International Prospective Register of Systematic Reviews database (registration number: CRD42022368029)., Results: The pooled proportion of termination of pregnancy was 32.3%. After the exclusion of cases of termination of pregnancy, the rate of spontaneous miscarriage or fetal demise was 20.1%, whereas the rate of live birth was 65.9%. The mean gestational age at delivery among the live-born cases was 27.3 weeks, and the mean latency between premature rupture of membranes and delivery was 39.4 days. The pooled proportion of cesarean deliveries was 47.9% of the live-born cases. Oligohydramnios occurred in 47.1% of cases. Chorioamnionitis occurred in 33.4% of cases, endometritis in 7.0%, placental abruption in 9.2%, and postpartum hemorrhage in 5.3%. Hysterectomy was necessary in 1.2% of cases. Maternal sepsis occurred in 1.5% of cases, whereas no maternal death was reported in the included studies. When focusing on neonatal outcomes, the mean birthweight was 1022.8 g in live-born cases. The neonatal intensive care unit admission rate was 86.3%, respiratory distress syndrome was diagnosed in 66.5% of cases, pulmonary hypoplasia or dysplasia was diagnosed in 24.0% of cases, and persistent pulmonary hypertension was diagnosed in 40.9% of cases. Of the surviving neonates, the other neonatal complications included necrotizing enterocolitis in 11.1%, retinopathy of prematurity in 27.1%, and intraventricular hemorrhage in 17.5%. Neonatal sepsis occurred in 30.2% of cases, and the overall neonatal mortality was 23.9%. The long-term follow-up at 2 to 4 years was normal in 74.1% of the available cases., Conclusion: Premature rupture of membranes before or at the limit of viability was associated with a great burden of both obstetrical and neonatal complications, with an impaired long-term follow-up at 2 to 4 years in almost 30% of cases, representing a clinical challenge for both counseling and management. Our data are useful when initially approaching such patients to offer the most comprehensive possible scenario on short- and long-term outcomes of this condition and to help parents in shared decision-making.

Purpose: Intraoperative warming is recommended for surgical patients under anesthesia, but there are insufficient studies on this topic in cesarean delivery patients under spinal anesthesia. The purpose of this study was to determine the effects of active warming on the mother and newborn during elective cesarean section., Design: This research was carried out in an experimental design with a pretest-posttest randomized intervention and control group., Methods: The research was conducted with 34 women (17 intervention and 17 control), who gave birth by cesarean section. The study examined outcomes for both mother and newborn. Women in the intervention group were heated by both active (warmed with carbon fiber resistive underbody heaters during surgery) and passive heating (preoperative- socks, nonelectrified wool blankets, etc). Only passive heating methods were applied to the women in the control group (preoperative). Neonatal Activity - Pulse - Grimace - Appearence - Respiration (APGAR) score, body temperature, cortisol, and blood glucose levels in the intervention and control groups were evaluated, while body temperature and shivering conditions were evaluated in the mother., Findings: Body temperature and first minute APGAR score of the infants in the intervention and control groups after cesarean section were 36.88 ± 0.27, 36.52 ± 0.32 (P = .002); 7.00 ± 0.36, 7.47 ± 0.64 (P = .009), respectively. Cortisol and blood glucose levels in the intervention and control groups were 3.55 ± 1.09, 4.51 ± 0.70 (P = .010), 77.94 ± 7.07, 72.47 ± 10.24 (P > .05), respectively. The body temperatures of the women in the intervention and control groups at 15, 30, and 45 minutes were significantly different (P < .05), while they were similar (P > .05) at 60 minutes. Oxygen saturation measured at 30 minutes during the operation was 97.10 ± 1.41 in the intervention group and 95.20 ± 1.78 in the control group (P < .05)., Conclusions: Active warming before, during, and after cesarean section affected body temperature, pulse, respiration, blood pressure, and oxygen saturation of women, and while it increased the body temperature and APGAR score of newborns, it decreased cortisol level., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest., (Copyright © 2024 The American Society of PeriAnesthesia Nurses.

Purpose of Review: There is an increasing awareness of the significance of intraoperative pain during cesarean delivery. Failure of spinal anesthesia for cesarean delivery can occur preoperatively or intraoperatively. Testing of the neuraxial block can identify preoperative failure. Recognition of the risk of high neuraxial block in repeat spinal in case of preoperative failure is important., Recent Finding: Knowledge of risk factors for block failure facilitates prevention by selecting the most appropriate neuraxial procedure, adequate intrathecal doses and choice of technique. Intraoperative pain is not uncommon, and neither obstetricians nor anesthesiologists can adequately identify intraoperative pain. Early intraoperative pain should be treated differently from pain towards the end of surgery., Summary: Block testing is crucial to identify preoperative failure of spinal anesthesia. Repeat neuraxial is possible but care must be taken with dosing. In this situation, switching to a combined spinal epidural or an epidural technique can be useful. Intraoperative pain must be acknowledged and adequately treated, including offering general anesthesia. Preoperative informed consent should include block failure and its management., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Background: Vesicouterine fistula (VUF) is a iatrogenic injury in the vast majority of cases. The worldwide increase of cesarean delivery rates is expected to lead to increased complications., Objectives: To assess current evidence on VUF pathogenesis and surgical management., Search Strategy: Pubmed and Embase databases were searched from January 2000 to January 2023 using relevant key words., Selection Criteria: Only original articles including either transabdominal or transvaginal surgical routes for post-cesarean VUF repair, in English language, were included., Data Collection and Analysis: Two authors independently screened the references for eligibility, data extraction, and assessment of methodologic quality. All available surgical outcomes were recorded., Main Results: Of the 1160 studies retrieved, 67 were selected for analysis. Most of these were case reports, case series, or observational cohort studies including a total of 284 patients. The majority (78.6%) of patients had more than one cesarean section, and approximately 10% of them experienced an overt bladder injury and/or uterine rupture at the time of cesarean delivery. The supratrigonal part of the bladder was most commonly involved (92.5%). The majority of patients (88.8%) underwent delayed VUF repair through laparotomy. Length of stay and blood loss were significantly less in patients treated via a minimally invasive approach (P < 0.001 and P = 0.02, respectively). Most patients had double-layer bladder repair and single-layer uterine repair. The overall success rate was 100% on first attempt for each independent combination of different surgical approaches and techniques. Live birth following VUF repair was reported in 23 patients., Conclusions: Paying close attention to surgical details is crucial to reduce the incidence of this complication and recurrence rates. Double-layer bladder closure and delayed timing of repair of VUF are recommended., (© 2023 International Federation of Gynecology and Obstetrics.)

Background and Objective: Spinal anesthesia remains the preferred mode of anesthesia for preeclamptic patients during cesarean delivery. We investigated the incidence of maternal hypotension under spinal anesthesia during cesarean delivery, by comparing different prophylactic infusion rates of norepinephrine with normal saline., Methods: We randomly allocated 180 preeclamptic patients (45 in each groups) aged 18-45 scheduled for cesarean delivery to receive one of four prophylactic norepinephrine infusions at doses of 0 (normal saline group), 0.025 (0.025 group), 0.05 (0.05 group), or 0.075 (0.075 group) µg/kg/min following spinal anesthesia. The primary endpoint was the incidence of maternal hypotension (systolic blood pressure < 80% of baseline)., Results: The incidence of maternal hypotension was reduced with different prophylactic infusion rates of norepinephrine (26.7%, 15.6%, and 6.7%) compared with normal saline (37.8%) with a significant decreasing trend (p = 0.002). As the infusion doses of norepinephrine increased, there is a significant decreasing trend in deviation of systolic blood pressure control (median performance error; median absolute performance error) from baseline (p < 0.001; p < 0.001) and need for rescue norepinephrine boluses (p = 0.020). The effective dose 50 and effective dose 90 of prophylactic norepinephrine infusion were - 0.018 (95% confidence interval - 0.074, 0.002) µg/kg/min and 0.065 (95% confidence interval 0.048, 0.108) µg/kg/min, respectively., Conclusions: Prophylactic infusion of norepinephrine, as compared to no preventive measures, can effectively reduce the incidence of maternal hypotension in preeclamptic patients under spinal anesthesia during cesarean delivery, without increasing other adverse events for either the mother or neonate., Registration: Clinical trials.gov identifier number NCT04556370., (© 2024.

Background: This study aimed to compare the analgesic effects of programmed intermittent epidural boluses (PIEB) and continuous epidural infusion (CEI) for postoperative analgesia after elective cesarean section (CS)., Methods: Seventy-four women who underwent elective CS were randomized to receive either PIEB or CEI. The PIEB group received 4 ml-intermittent boluses of 0.11% ropivacaine every hour at a rate of 120 ml/h. The CEI group received a constant rate of 4 ml/h of 0.11% ropivacaine. The primary outcome was the pain score at rest at 36 h after CS. Secondary outcomes included the pain scores during mobilization, time-weighted pain scores, the incidence of motor blockade, and complications-related epidural analgesia during 36 h after CS., Results: The pain score at rest at 36 h after CS was significantly lower in the PIEB group compared with that in the CEI group (3.0 vs. 0.0; median difference: 2, 95% CI [1, 2], P < 0.001). The mean time-weighted pain scores at rest and during mobilizations were also significantly lower in the PIEB group than in the CEI group (pain at rest; mean difference [MD]: 37.5, 95% CI [24.6, 50.4], P < 0.001/pain during mobilization; MD: 56.6, 95% CI [39.8, 73.5], P < 0.001). The incidence of motor blockade was significantly reduced in the PIEB group compared with that in the CEI group (P < 0.001)., Conclusions: PIEB provides superior analgesia with less motor blockade than CEI in postpartum women after CS, without any apparent adverse events.

Background: Placenta accreta spectrum is a serious condition associated with significant maternal morbidity and even mortality. The recommended treatment is hysterectomy. An alternative is 1-step conservative surgery, which involves the en bloc resection of the myometrium affected by placenta accreta spectrum along with the placenta, followed by uterine reconstruction. Currently, there are no studies comparing the 2 techniques in the setting of a randomized controlled trial., Objective: We performed a prospectively registered multicenter randomized controlled trial comparing hysterectomy with 1-step conservative surgery. The aim was to collect feasibility and clinical outcomes of the 2 techniques in women assigned to hysterectomy or 1-step conservative surgery. In addition to assessing participants' willingness to be randomized, we also collected data on intraoperative blood loss, transfusion requirement, serious adverse event, and other clinical outcomes., Study Design: Sixty women with strong antenatal suspicion of placenta accreta spectrum were assigned randomly to either hysterectomy (n=31) or 1-step conservative surgery (n=29)., Results: During a 20-month period, 60 of the 64 eligible patients (93.7%) underwent randomization. Intention-to-treat analysis showed that the clinical outcomes for 1-step conservative surgery were comparable to those of hysterectomy (median intraoperative blood loss, 1740 mL [interquartile range, 1010-2410] vs 1500 mL [interquartile range, 1122-2753]; odds ratio, 1 [1-1]; P=.942; median duration of surgery, 135 minutes [interquartile range, 111-180] vs 155 minutes [interquartile range, 120-185]; odds ratio, 0.99 [0.98-1]; P=.151; transfusion rate, 58.6% vs 61.3%; odds ratio, 0.96 [0.83-1.76]; P=.768; and adverse event rate, 17.2% vs 9.7%; odds ratio, 1.77 [0.43-10.19]; P=.398; respectively). In the subgroup of women with type 1 class on topographic classification, all participants allocated to 1-step surgery had successful outcomes, which were superior to those of hysterectomy. This was evidenced by the shorter surgery duration (median, 125 [interquartile range, 98-128] vs 180 [129-226] minutes; P=.002), lower transfusion rates (46.2% vs 82.4%), and fewer units of red blood cells transfused (median, 1 [interquartile range, 1-1.8] vs 3 [interquartile range, 2-4] units; P=.007)., Conclusion: A randomized controlled trial comparing 2 surgical techniques for the treatment of placenta accreta spectrum is feasible. One-step conservative repair is a valid alternative to hysterectomy in the large majority of cases, but this can only be ascertained following intraoperative surgical staging.
