We aimed to evaluate the effect of different routes of norepinephrine (NE) administration on maternal hypotension in pregnant females undergoing spinal anesthesia for caesarean section. 208 pregnant women were divided randomly into 4 groups (n=52). Bolus 4 µg/ml NE was administered intravenous (iv) immediately after spinal anesthesia in Group PB (Prophylactic Bolus). In Group PI (Prophylactic Infusion), 1 ml of saline solution was applied promptly after spinal anesthesia and then the NE infusion was started at 1 ml/min. In Group TB (Treatment Bolus), 1 ml Physiological Saline (PS) was administered after 1 ml/min infusion of PS immediately after spinal anesthesia and then 1 ml/min NE bolus when blood pressure decreased by 20% after the entry. In Group TBI (Treatment Bolus Infusion), 1 ml PS was administered after 1 ml/min infusion of PS immediately after spinal anesthesia, 1 ml NE and then 1 ml/min NE infusion was initiated when blood pressure decreased by 20% after the entry. At the 4th, 6th, and 8th minutes, the PI Group exhibited higher systolic and mean blood pressures than the other groups (p<.001). Additionally, hypotension was statistically lower in the PI Group than in PB, TB, TBI groups (p<.001), and episodes of hypotension, ephedrine required and extra NE boluses given were statistically lower in the PI Group than in the other groups (p<.001). Umbilical vein (UV) pH values were lower in the TBI Group at compared to the other groups (p<.001). It is suggested that a prophylactic infusion of 4 µg/min of NE in the prevention of hypotension following spinal anesthesia for cesarean section will reduce the possibility of maternal hypotension and better maintain fetal well-being than a prophylactic bolus, a treatment bolus or a posttreatment bolus infusion at the same dose.

PURPOSE: Health disparities continue to affect racial and ethnic marginalized obstetric patients disproportionally with increased risk of Cesarean delivery and pregnancy-related death. Yet, the literature on what influences such disparities in obstetric anesthesia service and its clinical outcomes is less well known. We set out to describe racial and ethnic disparities in obstetric anesthesia during the peripartum period in the USA via a scoping review of the recent literature. SOURCE: Using the Institute of Medicines definition of disparities, we searched the National Library of Medicines PubMed/Medline, Embase, Web of Science, APA PsycINFO, and Google Scholar for articles published between 1 January 2000 and 30 June 2022 to identify literature on racial and ethnic disparities in obstetric anesthesia. PRINCIPAL FINDINGS: Out of 8,432 articles reviewed, 15 met our inclusion criteria. All but one study was observational. Seven studies were single-institutional while the remaining used multicentre data/databases. All studies compared two or more race and ethnicity classifications. Studies in this review described disparities in the use of labour epidural analgesia, labour epidural request timing, anesthesia for Cesarean deliveries, postpartum pain management, and epidural blood patch for postdural puncture headaches. Several studies reported disparities observed in the unadjusted models becoming no longer significant when adjusted for other covariates. CONCLUSION: Based on the findings of the present scoping review on racial and ethnic disparities in obstetric anesthesia, we present an evidence map identifying knowledge gaps and propose a future research agenda.

The ex-utero intrapartum treatment (EXIT) is a rare surgical procedure performed in cases of expected postpartum fetal airway obstruction. This procedure technique lies in a safe establishment of a patent airway during labor in anticipation of a critical respiratory event, without the interruption of maternal-fetal circulation. Anesthetic management in the EXIT procedure is substantially different from that of the standard cesarean delivery and its main goals include uterine relaxation, fetal anesthesia, and placental blood flow preservation. We report the first case of an EXIT procedure performed on a fetus with a prenatal diagnosis of multiple oral masses at King Khalid University Hospital, Riyadh, Saudi Arabia.

We report the anesthetic management of a parturient with Takayasu arteritis and several comorbidities scheduled for elective cesarean section with the authorization of the institutional ethics committee. A twosegment combined spinal-epidural technique was used to provide anesthesia with close control of invasive arterial pressure and the use of Norepinephrine endovenous infusion. Likewise, a literature review of the two-segment combined technique for cesarean section in pregnant women with this disease was performed. [ABSTRACT FROM AUTHOR]

Objectives: The aim of the study was to compare, in patients undergoing minor gynecological laparoscopic procedures, the effects of ultrasound (US)-guided transversus abdominis plane (TAP) + rectus sheath (RS) block versus no TAP/RS block in terms of post-surgical pain control using the numeric pain rating scale (NRS) and the degree of patient satisfaction, according to the main goals of Early Recovery After Surgery (ERAS) programs. The primary outcome is to value the postoperative abdominal pain using NRS in both groups. Secondary outcomes are to evaluate blood values, presence of postoperative nausea and vomiting (PONV), postoperative ileus, level of patient expected satisfaction, time of discharge, length of stay (LOS), and the amounts of additional analgesics required. Design: In this prospective randomized controlled trial, patients were randomly assigned to loco-regional anesthesia (LRA) group, who received TAP and RS block under US guidance, or no loco-regional anesthesia (N-LRA) group. Enrolled patients were randomized 1:1 to either receive bilateral TAP/RS block with ropivacaine or sham treatment (patches were applied on the abdominal wall of the patients under general anesthesia). Participants: All patients aged between 18 and 75 years, with ASA (American Society of Anesthesiologists) physical status 1-2, undergoing laparoscopic minor gynecological surgery, were enrolled. Setting: The study was conducted to the University of Campus Bio-Medico Hospital of Rome. Methods: Half an hour before surgery, all patients received gabapentin 300 mg per os. Once the patient underwent general anesthesia, US-guided bilateral TAP/RS block was performed by the anesthesiology team, while the uterine manipulator was positioned by a gynecology resident (not involved in the study). In the operative room, all patients received the same standardized anesthetic regimen. Postoperative abdominal pain was assessed at rest, after palpation, during movement, and after a cough by evaluating the patient at 6, 12, 18, 24, 36, 48, and 72 h after surgery, using the NRS from 0 to 10 in both groups. The amount of drug used for analgesia in the first 48 h after surgery was recorded. Moreover, hemoglobin, white blood cells, and c-reactive protein levels were recorded at 24, 48, and 72 h. The presence of PONV and the postoperative ileus was recorded throughout convalescence. The expected level of patient satisfaction at discharge and finally the LOS were assessed. Limitations: The major weakness of this study is that 60 mL of 0.5% ropivacaine was administered to each patient, without considering weight differences, yet contemporary literature rarely suggests volume/dose titration in fascial blocks. Results: A total of 104 women, undergoing gynecological minor laparoscopic surgery, were enrolled and assigned to LRA group (53 pts) and N-LRA group (51 pts). Postoperative pain was significantly reduced in patients who received TAP/RS block. A reduction in the intake of non-steroidal anti-inflammatory drugs after surgery was registered in LRA group (p < 0.01). Moreover, a significant reduction of LOS (45.97 ± 9.87 vs. 65.08 ± 17.32 h; p < 0.01) and PONV was observed in the LRA group, as well as a better level of patient satisfaction at discharge (9.43 ± 0.94 vs. 8.26 ± 1.19; p < 0.01), compared to the N-LRA group. Conclusions: US-guided TAP and RS block significantly reduces postoperative pain after minor gynecologic laparoscopic surgery and improves patients' post-operative recovery. [ABSTRACT FROM AUTHOR]

Objective: Placenta accreta spectrum (PAS) is a high‐risk complication of pregnancy, which often requires complex surgical intervention. There is limited literature on the patient experience during the perioperative period and postpartum pain management for PAS. Therefore, this study aims to explore the patient perspective of anesthesia care. Methods: Ethical approval was granted by the hospital ethics committee (EC02.2023). This was a descriptive survey study, including women with a history of pregnancy complicated by PAS who were members of two patient advocacy groups. The survey, consisting of both open and closed questions, was performed over a 6‐week period between January and March 2023. Content analysis was performed on qualitative data to identify themes, and recommendations for care are suggested. Results: A total of 347 participants responded to the survey; 76% (n = 252) had a cesarean hysterectomy (n = 252), and general anesthesia was the most common primary mode of anesthesia (39%, n = 130). We identified two overarching themes: experiences of anesthesia and experience of postpartum pain management. Under experiences of anesthesia, three subthemes were identified, namely "communication with the anesthesiologist", "deferring to the expertise of the team", and "consequences of decision around the mode of anesthesia." Under postpartum pain management, two subthemes emerged: "support of specialist PAS team" and "poor pain management following PAS surgery". Conclusions: Women want to be involved in decisions around their care, but do not always understand the consequences of their decision‐making, such as missing the birth of their child. An antenatal anesthesiology consultation is important to provide women with information, explore preferences, and develop a plan of care for the birth. Synopsis: Women with placenta accreta spectrum valued being informed and involved in decision making around the mode of anesthesia for birth. [ABSTRACT FROM AUTHOR]

Objective: To explore the management and experiences of healthcare providers around anesthetic care in placenta accreta spectrum (PAS). Methods: This descriptive survey study was carried out over a 6‐week period between January and March 2023. Healthcare providers, both anesthesiologists and those involved in operative care for women with PAS, were invited to participate. Questions invited both quantitative and qualitative responses. Qualitative responses were analyzed using content analysis. Results: In all, 171 healthcare providers responded to the survey, the majority of whom were working in tertiary PAS referral centers (153; 89%) and 116 (70%) had more than 10 years of clinical experience. There was variation in the preferred primary mode of anesthesia for PAS cases; 69 (42%) used neuraxial only, but 58 (35%) used a combined approach of neuraxial and general anesthesia, with only 12 (8%) preferring general anesthesia. Ninety‐nine (61%) were offering a routine antenatal anesthesia consultation. Content analysis of qualitative data identified three main themes, which were "variation in approach to primary mode of anesthesia", "perspectives of patient preferences", and "importance of multidisciplinary team care". These findings led to the development of a decision aid provided as part of this paper, which may assist clinicians in counseling women on their options for care to come to an informed decision. Conclusions: Approach to anesthesia for PAS varied between healthcare providers. The final decision for anesthesia should take into consideration the clinical care needs as well as the preferences of the patient. Synopsis: Healthcare providers have varying approaches and preferences for anesthesia care in placenta accreta spectrum. [ABSTRACT FROM AUTHOR]

Background: Postdural puncture headache is a headache that occurs after a dura puncture, especially in caesarean sections, and affects patient comfort and mobilization. In this study, we compared the effects of pencil-tipped spinal needles and especially curved, bilateral atraumatic spinal needles in individuals undergoing elective caesarean sections. Methods: A total of 886 patients, aged 20-50 years, who had cesarean sections with spinal anesthesia and had American Society of Anesthesiologists II and III scores, were included in the study. The patients were allocated into 3 groups using the closed envelope randomization technique: Group 1 (n = 250) received spinal insertions using 25-gauge pencil-point needles; Group 2 (n = 245) received spinal insertions using 26-gauge atraumatic needles; and Group 3 (n = 250) received spinal insertions using 27-gauge pencil-point needles. Records were kept of the quantity of spinal needle referrals, the type of treatment, the length of hospital stays, and complications. Results: In the study, 745 patients who had cesarean section operations under spinal anesthesia were further analyzed. The mean incidence of post-dural puncture headache (PDPH) was 3.2% (n = 24). The incidence of PDPH was higher in group 2 than in group 3 and group 1 (Group 1: 2.8%; Group 2: 6.8%; Group 3: 0%) (P < 0.05). Among other complications, low back, back, shoulder, and surgical complications were similar for all 3 groups. Conclusion: In caesarean section operations, pencil-point spinal needles were found to have a lower incidence of postdural puncture headache than Atraucan-cut needles, regardless of needle thickness.

Recent years have witnessed remarkable strides in the domain of obstetric anesthesia and critical care, revolutionizing approaches to maternal and fetal well-being during pregnancy, labor, and delivery. This review synthesizes the latest advancements, highlighting significant developments in regional anesthesia techniques, perioperative care enhancements, emerging trends in critical care, advances in anesthetic pharmacology, and the integration of technology. Advancements in regional anesthesia techniques, including refined neuraxial approaches and emerging alternatives like TAP and ESP blocks, have transformed pain management strategies, prioritizing maternal comfort while ensuring safety for both mother and fetus. Perioperative care improvements encompass comprehensive preoperative assessments, optimized intraoperative management, and tailored postoperative care, optimizing outcomes for obstetric patients undergoing surgery. Emerging trends in critical care underscore the importance of multidisciplinary approaches, focusing on managing obstetric emergencies like hemorrhage and hypertensive disorders. Advances in anesthetic pharmacology emphasize personalized dosing regimens, safety profiles of anesthetic agents, and novel drug delivery systems to optimize pain relief while minimizing risks. Furthermore, the integration of technology, such as ultrasound-guided techniques, telemedicine, and digital health platforms, has enhanced precision in procedures, facilitated remote monitoring, and streamlined communication among healthcare providers. This comprehensive review sheds light on the evolving landscape of obstetric anesthesia and critical care, emphasizing the multidimensional advancements that contribute to improved maternal and neonatal outcomes.

Objective: Each repeat cesarean section (CS) potentially adds surgical complexity. The determination of appropriate anesthesia strategy to meet the surgical challenge is of crucial importance for the maternal and neonatal outcome. Study design: This prospective cohort study was conducted from 1-Jan-2021 to 31-Dec-2021 at a single large obstetric centre of all repeat CS. We compared the characteristics and the appropriateness of the anesthesia techniques for low-order repeat CS (LOR-CS) (1 or 2 previous CS) and high order repat CS (HOR-CS) group (3 or more repeat CS). Results: During the study period, 1057 parturients met the study entry criteria, with 821 parturients in the LOR-CS group and 236 parturients in the HOR-CS group. The use of spinal anesthesia was more common for HOR-CS 84.3%. Overall surgical time varied between LOR-CS (38 min, 29–49) and HOR-CS (42 min, 31–57) (p = 0.004).The rate of moderate and severe adhesions was relatively high in HOR-CS and the duration of overall surgical time for cases with mild adhesions was 38 min (29–48), for moderate adhesions was 44 min (34.8–56.5), and for severe adhesions was 56 min (44.8–74.3). There was no significant difference in the Estimated Blood Loss (EBL) between LOR-CS and HOR-CS, with values of 653 ± 292 ml vs. 660 ± 285 ml, respectively. Conclusion: Our data indicate that spinal anesthesia, standard monitoring and regular anesthetic setup are safe and suitable for the majority of HOR-CS, except in cases with high suspicion of placental accreta spectrum.

The prevalence of cardiac disease-related maternal morbidity and mortality is on the rise in the United States. To ensure safe management of pregnancy in patients with cardiovascular disease, pre-delivery evaluation by a multidisciplinary Pregnancy Heart Team should occur. Appropriate anesthetic, cardiac, and obstetric care are essential. Risk stratification tools evaluate the etiology and severity of cardiovascular disease to determine the appropriate hospital type and location for delivery and anesthetic management. Intrapartum hemodynamic monitoring may need to be intensified, and neuraxial analgesia and anesthesia are generally appropriate. The anesthesiologist must be prepared for obstetric and cardiac emergencies. [ABSTRACT FROM AUTHOR]

Congenitally corrected transposition of the great arteries (CCTGA) is a rare form of congenital heart disease often associated with other cardiac defects. The adaptations and physiologic changes in pregnancy can present maternal challenges and complications; multidisciplinary care allows for the safest management of pregnancy and delivery in these patients. We present a case of the anesthetic management of cesarean delivery in a woman with CCTGA with her pregnancy complicated by recurrent volume overload, pulmonary hypertension, and dysrhythmias.

PurposeGiving birth is the most common reason for hospital admission, with Cesarean delivery being the most frequently performed inpatient surgery. Through a needs assessment and iterative design process involving patients and obstetric anesthesiologists, we previously developed a mobile application, C-Care, for patients undergoing Cesarean delivery. The focus of C-Care is perioperative education and self-monitoring of potential anesthetic complications. This study aimed to obtain feedback on patient engagement with C-Care.MethodWe conducted a prospective cohort study of patients ≥ 18 yr (n = 36) undergoing elective Cesarean delivery. Anonymous usage data were recorded for 30 days. On postoperative days 1-5, participants received daily self-monitoring questionnaires within C-Care. Fourteen days after surgery, participants received an online survey regarding satisfaction and use of C-Care.ResultsThirty-five out of 36 participants visited the application after orientation, with a median [interquartile range (IQR)] age of 32 [31-36] yr. Each participant visited the application a median of 15 [9-31] times over 30 days and completed a median of 3 [2-4] out of five self-monitoring questionnaires. Each participant viewed a median of 4 [2-7] out of eight education topics, with the most viewed patient education topics being "Controlling Pain" and "The First Few Days". Visits to the application were highest in the first week postpartum. Of the 18 respondents who completed the day 14 survey, 83% (n = 15) participants would recommend C-Care to other women, and the median participant satisfaction score was 7.5 out of 10 (range, 2-10).ConclusionMost participants used this mobile application for patient education and self-monitoring after elective Cesarean delivery. Insights into patient engagement with C-Care after Cesarean delivery could help design more effective perioperative mobile telehealth programs.Trial registrationwww.ClinicalTrials.gov (NCT03746678); registered 5 November 2018.

Abstract Background Spina bifida is a relatively common congenital malformation. As the functional prognosis of patients with spina bifida has improved over time, the number of cases resulting in pregnancy and delivery has increased. Lumbar ultrasonography has become a standard and helpful technique before neuraxial anesthesia. We believe that it might be valuable if we use lumbar ultrasonography to evaluate pregnant women with spina bifida before obstetric anesthesia. Case presentation We performed lumbar ultrasonography to evaluate four pregnant women with spina bifida. Patient 1 had no history of surgery. Lumbar radiography before pregnancy showed a bone defect from L5 to the sacrum as a result of incomplete fusion. Magnetic resonance imaging showed a spinal lipoma and a bone defect of the sacrum. Lumbar ultrasonography showed similar findings. We performed general anesthesia for emergency cesarean delivery. Patient 2 underwent surgical repair immediately after birth. Lumbar ultrasonography showed the same bone defect as well as a lipoma beyond the bone defect. We performed general anesthesia for cesarean delivery. Patient 3 had vesicorectal disorders but no prior surgery. Lumbar radiography before pregnancy showed congenital abnormalities such as incomplete fusion, scoliosis, rotation, and a notably small sacrum. Lumbar ultrasonography showed the same bone defect. We performed general anesthesia for cesarean section with no complications. Patient 4 complained of lumbago a few years after her first delivery and received a diagnosis of spina bifida occulta by lumbar radiography, with the incomplete fusion of only the 5th vertebra. Lumbar ultrasonography indicated the same abnormalities. We placed an epidural catheter to avoid the bone abnormality and achieved epidural labor analgesia with no complications. Conclusions Lumbar ultrasonography shows anatomic structures easily, safely, and consistently, without X-ray exposure or the need for more expensive modalities. It is a helpful technique to explore anatomic structures potentially complicated by spina bifida before anesthetic procedures.

The emergence of obstetric anesthesia in the second half of the nineteenth century was preceded by a transformation in the medical conceptualization of women's pain. In the eighteenth and early nineteenth centuries, physicians described pain in physiological terms as natural and unproblematic, but in the second half of the nineteenth century they adopted a newly emotional language that emphasized women's subjective experiences of suffering. Middle-class and elite white women shaped this transition by insisting that their physical and emotional anguish was extreme. Women's attitudes, combined with a growing perception that sensibility to pain was a marker of "civilization," pushed physicians to view suffering as real and problematic. As they began to depict pain relief as an urgent medical concern, physicians envisioned refined white women as the primary beneficiaries of their new technology; this perspective paved the way for the increasingly routine use of anesthesia for middle-class and elite white women.

Ebstein anomaly is a rare congenital cardiac condition associated with displacement and incompetence of the tricuspid valve. Peripartum anesthetic management can be particularly challenging since these patients are at high risk of cardiac failure and tachyarrhythmias. Risk stratification is important since it helps to identify high-risk patients who should deliver at a tertiary care center where a multidisciplinary team (obstetrics, cardiology, anesthesiology, and neonatology) is immediately available. We describe the peripartum anesthetic management of 9 patients with Ebstein anomaly who underwent 12 deliveries at our institution. All patients tolerated neuraxial anesthesia and analgesia well. No maternal or fetal deaths occurred. [ABSTRACT FROM AUTHOR]

Enhanced recovery after cesarean delivery (ERAC) is an evidence-based interdisciplinary protocol with an aim to improve quality of care and patient satisfaction while lowering health care cost by reducing length of hospital stay. It is an approach that combines several evidence-based perioperative care components to hasten patient recovery. ERAC uses multidisciplinary approach with inclusion of all stakeholders including anesthesiologists, obstetricians, pediatricians, nurses, pharmacists, patients, and hospital administration. Therefore, institutional support, local infrastructure, and compliance of all supporting systems are necessary for the successful implementation of ERAC. The role of anesthesiologists in implementation of standardized care cannot be disregarded as they are involved in the provision of perioperative services to improve maternal outcomes and healthcare quality. The purpose of this narrative review is to explore the components and guidelines from the enhanced recovery after surgery for caesarean delivery, highlight the responsibility of anesthesiologists in the existing and emerging ERAC programs and the difficulties associated with implementing the ERAC in resource-constrained environments.

Aim: This single‐center observational study aimed to investigate the association between labor neuraxial analgesia (LNA) and neonatal outcomes. Methods: We conducted a retrospective cohort study at a tertiary perinatal center and included all vaginal deliveries performed between November 2015 and December 2021. Obstetric and neonatal outcomes were compared between deliveries with LNA (LNA group) and without analgesia (control group). Propensity score (PS) matching was used for statistical analysis. Results: We included 2343 singleton deliveries performed in 1367 nulliparous and 976 multiparous women, in whom LNA was induced in 352 and 178 deliveries, respectively. After PS matching, the nulliparous LNA group had a significantly higher incidence of Apgar scores <7 at 1 (7.1% vs. 3.6%, p = 0.0139) and 5 min (2.3% vs. 0.7%, p = 0.0397) and meconium staining (29.8% vs. 23.2%, p = 0.0272) than the nulliparous control group. Other neonatal outcomes, including umbilical artery pH and neonatal intensive care unit admission rate, were comparable between the nulliparous LNA and control groups. No significant differences in neonatal outcomes were seen in multiparous women. Regarding fetal heart rate abnormalities, severe late deceleration (4.8% vs. 1.7%, p = 0.0036) and severe prolonged deceleration (17.0% vs. 11.9%, p = 0.0224) were more common in the nulliparous LNA group than in the nulliparous control group, and the multiparous LNA group exhibited more severe variable deceleration (21.3% vs. 14.3%, p = 0.0485) than the multiparous control group. Conclusion: Our findings suggest that LNA is associated with short‐term adverse neonatal and obstetric outcomes in vaginal deliveries. LNA should be performed with precautionary measures and adequate medical resources. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study is to examine the relationship between the measurement of anterior neck soft tissue thickness and the difficult laryngoscopy in which cesarean section under general anesthesia. Our secondary aim is to determine the efficacy of the other predictive tests and post-induction indicators to detect difficult laryngoscopy in pregnant women. Materials and Methods: One hundred fiftytwo pregnant women (18-45 years old, American Society of Anesthesiologists Physical Status Class II) were included. According to Cormack and Lehane’s scale (Grade I-II: easy laryngoscopy, Grade III-IV: difficult laryngoscopy) patients were divided into two groups. The distance from the skin to the anterior aspect of the trachea was measured at five different levels (hyoid bone, thyrohyoid membrane, vocal cords, thyroid isthmus, and suprasternal notch) with ultrasound. In addition, the other predictive tests and post-induction indicators for predetermining difficult laryngoscopy were recorded. Results: There was no significant difference in the anterior neck soft tissue ultrasound measurements between the groups. Having limited mouth opening (4.80±0.51cm), buck teeth (20%), high Wilson's Risk Score (0.73±0.82), large neck circumference (41.40±2.96cm), inability to bite the upper lip (43%), and high Modified Mallampati Score (33%) were seen statistically significantly more common in the difficult laryngoscopy group. In addition, ‘‘Backward, Upward, Rightward Pressure’’ maneuver, use of gum elastic bougie, high Intubation Difficulty Score, and >2 intubation attempts were more frequently found in the difficult laryngoscopy group. Conclusion: Measuring the anterior neck soft tissue with ultrasound is ineffective for determining difficult laryngoscopy in pregnant women. On the other hand, Mallampati Score, upper lip bite test, mouth opening, neck circumference, buck teeth, and Wilson's Risk Score can be helpful in the determination of difficult laryngoscopy in pregnancies.

Objective To assess whether an early recovery after surgery (ERAS) pathway after scheduled cesarean delivery was associated with a reduction in postoperative length of stay compared with standard perioperative care. Methods This was a prospective pre- and post-intervention study. Women were included if they were between 18 and 45 years of age and delivered a singleton, term, non-anomalous fetus via scheduled cesarean delivery by a provider within an academic practice. The ERAS pathway consisted of 23 evidence-based components regarding preoperative, intraoperative, and postoperative care. The primary outcome was the rate of postoperative length of stay of 3 or more days. Secondary outcomes included total postoperative narcotic use, postoperative complications, 30-day hospital readmission rates, and quality of recovery questionnaire scores. Results A total of 116 women were included. There were no significant differences in patient characteristics between the pre- and post-implementation groups in the post-implementation group, surgery time was longer (78.3 ± 27.8 vs 59.1 ± 19.2 min, p < .001) and blood loss volume was higher (910.3 ± 405.1 vs 729.1 ± 202.0, p = .003), compared to pre-implementation group. An ERAS pathway was not associated in a significant reduction in postoperative length of stay of 3 or more days (70.7% vs 75.9%, p = .529). It was also not significantly associated with a difference in postoperative narcotic use, maximum pain score, transfusion, postoperative complications or hospital readmission rates. Conclusion An early recovery after surgery pathway after scheduled cesarean delivery was not associated with a reduction in postoperative length of stay or narcotic use, though the recovery scores were better after implementation.

Abstract Background Although restricting food intake during labor is recommended by guidelines, intrapartum starvation has not been popular in some regions. We conducted this comparative cross-sectional study to determine the prevalence of risk stomach in non-fasted laboring women compared with fasted non-laboring women using gastric ultrasound. Methods Ultrasound examination of the antrum was performed in 50 term fasted non-laboring women before elective cesarean delivery and 50 laboring women allowed to eat and drink during active labor. Examinations consisted of the qualitative (antral grades, 0–3) and quantitative evaluation (antral cross-sectional area and calculated gastric volume) in the supine and right lateral decubitus (RLD) position. A risk stomach was defined as an antral grade ≥ 2 or grade 1 with gastric volume ≥ 1.5 ml· kg− 1. Results No non-laboring women had grade ≥ 2, while 34 (68%) laboring women had grade ≥ 2. Nine (18%) non-laboring and 40 (80%) laboring women presented risk stomach (P

Introduction: Quality assessment of provided healthcare is becoming a standard in numerous health institutions worldwide, which is beneficial for both the patient and the institution. In order to achieve this standard, it is necessary to develop quality indicators in all segments of healthcare. Postdural puncture headache is a common complication following neuraxial blocks, especially in obstetric anesthesia. If severe, it is a cause of emotional and psychological distress and must be treated by a blood patch. Aim: The aim of this study was to determine whether the number of these complications is reduced when blood patch frequency is monitored and analyzed and to assess the effect of countermeasures in order to improve the quality and safety of regional anesthesia in obstetrics. Methods: Before 2009 and during that year at the University Hospital Sveti Duh, there had been a large number of severe postdural puncture headaches after spinal anesthesia and epidural analgesia treated by a blood patch in 6.12% of cases. After noticing the rising number of blood patches, we decided to analyses data every year. We recorded all blood patches injected to obstetric patients within the period of nine year, from 2009 to 2018 and concurrently we introduced a set of measures to improve the quality of neuraxial blocks, such as the use of atraumatic 26 or 27-gauge pencil-point spinal needles and modern neuraxial blockade protocols. Data were collected from anesthesiology and gynecology protocols and analyzed with MedCalc software, version 18.1.2. Results: The frequency of blood patch applications has been reduced from 6.12% to 0.30%, which is statistically significant. The percentage of placed epidural catheters for vaginal birth increased from 21% in 2009 to 38% in 2018. Although not statistically significant, the number of pregnant women undergoing a caesarean section is also growing, while the total number of births is falling. The proportion of cesarean sections in spinal anesthesia varies from year to year. Discussion: A statistically significant decrease in the number of installed blood patches clearly indicates the positive effect of measures taken to improve quality, which could contribute to the growing interest of pregnant women in childbirth in epidural analgesia. The number of placed epidural catheters is increasing despite the decline in the total number of deliveries and the increase in the number of deliveries completed by cesarean section. Conclusion: Monitoring the incidence of severe post-puncture headaches treated with blood patches has shown great progress in improving the quality and safety of regional anesthesia and analgesia in our institution, so we believe that monitoring the number of blood patches could serve as an indicator of regional anesthesia and analgesia in obstetrics. Monitoring the number of blood patches shows that the frequency of post-puncture headaches does not correlate only with the type of needle or epidural catheter used for neuroaxial blocks, but is also a sensitive indicator of any deviations from the achieved standards. Furthermore, it indicates the need for careful analysis of causes in order to adopt and implement appropriate countermeasures.

Background and Aims: To evaluate the rate and risk factors of labor epidural conversion failure requiring general anesthesia for Caesarean delivery (CD). Material and Methods: Pregnant patients requiring conversion from labor to CD with a pre-existing labor epidural at our institution from 2009 to 2014 were identified. Through a retrospective review, we compared successful epidural conversion with those who required general anesthesia for CD. Patient characteristics were analyzed to identify risk factors for failed epidural conversion for CD. Results: A total of 673 patients were included in the study. The rate of epidural conversion failure was 21%. Main risk factors for epidural conversion failure requiring general anesthesia included: younger maternal age (95% CI 0.94, P = 0.0002) and supplementation of intravenous fentanyl (95% CI 0.19, P < 0.0001) or midazolam (95% CI 0.26, P = 0.0008) during CD. A higher risk of conversion failure was also associated with a more urgent CD (CD category 1, 2, and 3 vs category 4). Conclusion: Consistent with previous reports, young age and the urgency of CD increases the likelihood of epidural conversion failure. While conversion failure is likely multifactorial and complex, many of these factors are suggestive of inadequate and poorly functioning labor epidurals prior to CD. Prospective studies to further evaluate these factors are necessary, and the best prevention of epidural conversion failure is diligent diagnosis and evaluation of ineffective labor epidural analgesia prior to impending CD.

Abstract With an increase in Coronavirus Disease 2019 (Covid-19) incidents around the world, it has become more important than ever to be prepared for the uncertain context of labor and delivery in obstetrics. As medical staff did not encounter such a situation previously, no prior knowledge and guidelines were present to assist them. During the care of obstetric women infected with COVID-19 as well as those who are suspected of COVID-19 infection, there are two objectives, the care of asymptomatic to severely sick pregnant and postpartum women and preventing exposure of medical professionals and others during childbirth hospitalization. The focus of this review is to provide anesthesiologists who are dealing with infected pregnant mothers with some facts or, as data is insufficient, expert opinion, with an emphasis on awareness and optimal medical obstetric anesthesia training. This review will provide possible recommendations for the obstetric anesthesiologists when treating infected obstetric women and these recommendations also help anesthesia providers to prepare themselves for future pandemics.

This report describes the case of a pregnant woman who arrived for preanesthetic assessment of External Cephalic Version (ECV) for fetus in breech presentation and cesarean section in case of ECV failure. Although the technique seems simple, attempts to rotate the fetus can result in elevated intracranial pressure, which might cause malformation bleeding. The most appropriate anesthetic technique in cases of arteriovenous malformations during C-sections has not been determined. Neuroaxial anesthesia is safe only in stable brain cavernomas, but the presence of spinal malformations contraindicates it. Anesthetic goals include stabilizing the blood pressure and reducing the risk of rupture.

Neonatal resuscitation training is a requirement for all obstetric anesthesia fellows. However, while the majority of anesthesiologists who work on labor and delivery report having been involved in the resuscitation of a newborn, most do not have NRP training. By studying a national cohort of anesthesiologists, our objective was to identify factors associated with knowledge and comfort with neonatal resuscitation and to inform decisions about neonatal resuscitation in obstetric anesthesia fellowship training. After receiving exempt status, a survey assessing knowledge and comfort with neonatal resuscitation was sent to US academic institutions. Univariable and multiple variable regression analyses were performed to assess factors associated with knowledge and comfort. All statistical analyses were performed using R software (R version 3.4.3 [2017-11-30]; R Foundation for Statistical Computing, Vienna, Austria). Responses were received from 32 (84%) of 38 academic institutions that participated. A total of 245 surveys were collected from 20 December 2018 to 27 September 2019. The mean (standard deviation (SD)) percentage of correct knowledge answers in the cohort was 43.3% (22.6%). Knowledge scores were associated with obstetric anesthesia fellowship training, regularly working with infants, and current neonatal resuscitation program (NRP) training. The mean (SD) sum of comfort ratings from the individual questions was 49.9 (17.9). Comfort ratings were associated with pediatric anesthesia fellowship training, regularly working with infants, current NRP training, and having at least one year of general pediatrics residency training. Obstetric anesthesiologists have the knowledge but appear to lack the comfort to perform neonatal resuscitation. As obstetric anesthesiologists are sometimes involved in neonatal resuscitation, maintenance of certification is important in maintaining comfort with neonatal resuscitation if not regularly working with infants.

The importance of breastfeeding with its positive impact on the wellbeing of the mother-infant pair is well established. Anesthesiologists should encourage the promotion of lactation by being willing to give reassurance during the preoperative period and preparing a plan that does not interfere with safe breastfeeding. There is concern regarding the transfer of drugs into breast milk, which may lead to inconsistent advice from many health professionals and to early discontinuation. However, evidence shows that most anesthetic drugs are safe in terms of transfer into breast milk, and hence, compatible with breastfeeding, which should be resumed after anesthesia as soon as the mother is alert and feels well enough to hold her infant, without the need to "pump and dump". This review provides pharmacokinetic information on commonly used anesthesia drugs and their passage into breast milk, to help practitioners discuss risks and benefits with the mother, emphasizing that anesthesia should not interfere with the benefits of breastfeeding. Four practical clinical scenarios are presented: pregnant women concerned about the effect of epidural analgesia on subsequent breastfeeding, spinal anesthesia for c-section and lactation, patients who will receive general anesthesia during cesarean section, and finally women who are breastfeeding and require anesthesia for elective or urgent surgery. Neuraxial anesthesia allows for better pain control and immediate skin-to-skin contact at the time of childbirth. Also, it interferes the least with the woman's ability to care for her infant. Regional techniques, opioid-sparing techniques and outpatient surgery are preferred. Drugs such as opioids and longer-acting benzodiazepines should be administered cautiously, particularly in repeat doses. [ABSTRACT FROM AUTHOR]

The current status of general anesthesia practice for cesarean delivery in Japan remains unknown. Therefore, using a nationwide claims database, we aimed to investigate general anesthesia use for cesarean delivery over a period of 15 years, and to analyze the general anesthesia practice in Japan. Patients who claimed the Japanese general anesthesia claim code (L008) for cesarean delivery between 1 January 2005, and 31 March 2020, were analyzed. Primary endpoint was the prevalence of general anesthesia use. We used two definitions of general anesthesia: L008 code only (insurance definition) and combination of the L008 code with muscle relaxant use (clinical definition). The general anesthesia claim cohort (L008) included 10,972 cesarean deliveries at 1111 institutions from 2005 to 2020. Muscle relaxants were used in 27.3% of L008 claims cases. The rate of general anesthesia use for cesarean delivery ranged from 3.9% in clinical definition to 14.4% in insurance definition of all cesarean deliveries. We observed a temporal trend of gradual decrease in general anesthesia use, regardless of its definition (p for trend < 0.001). We recommend the clinical definition of general anesthesia as the combination of L008 code and muscle relaxant use in a claims-based approach. [ABSTRACT FROM AUTHOR]
