ABSTRACT Objective Design Setting Population Methods Main Outcome Measures Results Conclusions To assess the association between the decrease in the use of episiotomy and the incidence of obstetric anal sphincter injuries (OASIS) over a 10‐year period and understand their reasons by interviewing obstetricians and midwives.Mixed‐methods study.A tertiary university public maternity hospital, Paris, France.All patients who delivered vaginally between January 2012 and December 2021 in the maternity hospital and 20 interviews with obstetrician‐gynaecologists and midwives.Quantitative data analysis using a multivariate logistic regression model, stratifying on the mode of delivery. Semi‐structured interview with 20 obstetricians and midwives, with an interview guide.Obstetric anal sphincter injuries.The quantitative study of 37 942 women (16.1% of whom had an episiotomy and 1.4% OASIS) shows that, the incidence of episiotomy decreased from 25% to 7.6% over this 10‐year period. Allow on the known risk factors for OASIS, we demonstrate that its incidence rose (adjusted odds ratio 1.35, 95% confidence interval 1.09–1.67) for the years in which the episiotomy incidence fell below 10% for the overall population. The interviews showed professionals' apparent awareness that the decreased incidence in episiotomy (achieved by changes in departmental policy, redefining its benefit/risk balance and acquiring new skills to manage the expulsion phase) could lead to an increased incidence of OASIS.Decreasing the episiotomy incidence appears to be associated with a rising incidence of OASIS. The optimal incidence of episiotomy remains controversial in the literature and among professionals. [ABSTRACT FROM AUTHOR]

Introduction: Newer neuraxial local anesthetic agents which have been used as epidural analgesia have shown to provide reliable pain relief during labor. Ropivacaine and levobupivacaine are newer agents now used for labor analgesia. However, even though few studies have made their comparison with bupivacaine, ropivacaine and levobupivacaine have seldom systematically been compared. Therefore, in this analysis, we aimed to systematically show the impact of epidural ropivacaine versus levobupivacaine for labor analgesia on maternal and fetal outcomes. Methods: http://www.clinicaltrials.gov, Web of Science, MEDLINE, EMBASE, Cochrane database and Google Scholar were searched for studies comparing ropivacaine versus levobupivacaine for labor analgesia. Maternal and fetal outcomes were considered as the endpoints in this analysis. The RevMan software 5.4 was used to analyze data in this study. Risk ratio (RR) with 95% confidence intervals (CI) were used to represent the data post analysis. Results: A total number of 2062 participants were included in this analysis whereby 1054 participants were assigned to ropivacaine and 1008 participants were assigned to levobupivacaine. The main results of this analysis showed that epidural ropivacaine was not associated with significantly higher risk of hypotension (RR: 0.71, 95% CI: 0.43 – 1.17; P = 0.18) and pruritus (RR: 1.12, 95% CI: 0.89 – 1.42; P = 0.34) when compared to levobupivacaine for labor analgesia. However, the risk of nausea and vomiting was significantly higher with ropivacaine (RR: 1.60, 95% CI: 1.05 – 2.44; P = 0.03). Spontaneous vaginal delivery (RR: 0.99, 95% CI: 0.89 – 1.42; P = 0.83), instrumental vaginal delivery (RR: 1.13, 95% CI: 0.89 – 1.45; P = 0.32) and the risk for cesarean section (RR: 0.76, 95% CI: 0.42 – 1.37; P = 0.35) were not significantly different. When fetal outcomes were assessed, Apgar score < 7 at 1 min (RR: 1.01: 95% CI: 0.57 – 1.80; P = 0.97), abnormality of fetal heart rate (RR: 1.45, 95% CI: 0.55 – 3.79; P = 0.45) and neonatal asphyxia (RR: 0.35, 95% CI: 0.10 – 1.18; P = 0.09) were also similarly manifested. Conclusions: To conclude, our analysis showed both epidural ropivacaine and levobupivacaine to be equally effective for labor analgesia in terms of maternal and fetal outcomes. No major adverse maternal and fetal outcome was observed in this analysis. However, considering the several limitations of this analysis, further larger studies should be able to solve and clarify this issue. [ABSTRACT FROM AUTHOR]

Background: This study was designed to inspect the effectiveness of Hypopressive exercise and Kegels exercise for pelvic organ prolapse among patients with spontaneous vaginal delivery. Pelvic organ prolapse is when one or more organs of the pelvis slip down from their normal position and bulge into vagina. Hypopressive exercises help to rectify the prolapse and minimizes its severity. Kegels exercises are usually done for pelvic floor muscle training. Purpose: To compare the effectiveness of Hypopressive and Kegels exercise for pelvic organ prolapse among spontaneous vaginal delivery. Materials and Methods: Total of 42 participants were selected from C3 Care Cure Comfort clinic according to inclusion and exclusion criteria, and the participants were explained about the treatment and written consent were obtained. The subjects underwent study for a time period of 4 months from April 2023-July 2023 and results were obtained. The participating subjects were randomly allocated into two groups, Hypopressive exercise group "and" Kegels exercise group. All the subjects underwent pre-test measurement with modified oxford scale and pelvic floor impact questionnaire at the beginning of the treatment. Results: statistical analysis of data showed significant differences not only in the Hypopressive group but also in the Kegels exercise group. The Hypopressive group was significantly higher than Kegels exercise group, with a p value of <0.0001. Conclusion: Hypopressive exercise is more effective than Kegels exercise for pelvic organ prolapse among spontaneous vaginal delivery. The study was done for a short period of time with a small group of people. [ABSTRACT FROM AUTHOR]

Background: The outcome of spontaneous vaginal birth is improved using analgesics during the three phases of labour. Both pharmaceutical and non-pharmaceutical approaches have been tried. Therefore, this study aimed to compare parenteral ketamine and tramadol regarding their analgesic effect and maternal and labor outcome.Patients and Methods: This randomized clinical trial was conducted on 100 primigravida and multigravida women. The study population was randomized into two equal groups; ketamine group: received low dose ketamine 0.4 mg/kg body weight intravenous [IV] slowly over 30-60 seconds with maintenance dose at the rate of 1 mg/min in normal saline after 30 min of induction dose using an infusion pump and the tramadol group: 1 mg/kg iv slowly for 5-10 minutes then after 30 min we start maintenance by IV Tramadol 0.3 mg /kg/hr.Results: Ketamine significantly decreased the time of onset analgesia [p=0.036] and VAS [p=0.002] than tramadol. Ketamine has a significant advance in patient satisfaction than tramadol. The duration of all 3 stages of labor, Apgar score after 1 min, Apgar score after 5 min, and the percentage of maternal complications did not exhibit any significant change between both groups.Conclusion: In spontaneous vaginal delivery, ketamine and tramadol are considered safe drugs with low complications and similar Apgar scores after 1 min and also after 5 min with superiority of ketamine than tramadol regarding the earlier time of onset analgesia, lower VAS score and better patient satisfaction.

Background: Globally, the overall prevalence of caesarean section (CS) is estimated at 18.6%, with 27% in high-income countries and 6% in low- and middle-income countries. There is an increase in trends of CS in Uganda from 8.5% in 2012 to 11% in 2016. No studies have been carried out to account for the high rates of CS at Kisiizi Hospital in Uganda. This study determined the proportion and factors associated with CS delivery at a rural hospital in southwestern Uganda. Methods: This was a cross-sectional study of 321 immediate postnatal women in a rural hospital in southwestern Uganda. A structured questionnaire and data abstract forms were used to collect information on the proportion and factors associated with CS. Eligible participants were enrolled consecutively. Logistic regression analysis was done to identify the factors associated with CS taking into account potential confounders. Results: This study recruited 321 women with a mean age of 25.8 ± 6.086 years, mean parity of 2.6 ±1.673 and mean antenatal care visits of 4.27 ± 1.197. The proportion of CS in this study was 38.3% (123/321). Of these, 110 (89.4%) were emergencies and 27(10.6%) were electives. Only 8.4% of the respondents were referrals. The commonest indications of CS were fetal distress (28.5%), history of previous CS (18.7%), and poor progress of labour (11.4%). No factors were significantly associated with CS in this study. Conclusion: There is a high proportion of CS at Kisiizi Hospital in Uganda and this is three times higher than the WHO-recommended CS rates. The majority of CS are emergencies due to fetal distress and poor progress of labour. There is a need for additional studies exploring the reasons for the much higher-than-expected CS rates.

To establish anatomical structures responsible for creating a resistance force on a fetal head during vaginal delivery at term; to develop a new episiotomy to widen the vaginal outlet. A prospective observational case series study. International centers. Eighteen consecutive women at term during vaginal delivery. V-shape excision made on the hymeneal membrane, hymeneal ring, and hymeneal plate without extending an incision to the posterior perineal structures. Outlectorrhaphy (repairing the vaginal outlet to repair the surgical defect. Excisional specimens are subjected to histological examinations. The primary maternal outcome measures were postpartum posterior perineum pain associated with vaginal outlectomy. The secondary outcomes measured a) complication of vaginal outlectomy; b) occurrence of dyspareunia after vaginal outlectomy; c) applicability of vaginal outlectomy; d) neonatal outcome measured by an APGAR score to show how the neonate tolerated the vaginal delivery process with vaginal outlectomy implementation. The V-shape excision widened the vaginal outlet sufficiently for a vaginal delivery without a perineal incision. Outlectorrhaphy requires two or three simple interrupted sutures to close surgical defects and eliminate the vaginal gapping appearance. Eleven out of eighteen women were primigravida (61.1 %), and four multiparas (38.9 %) delivered a live newborn vaginally with a newly developed vaginal outlectomy. A median newborn's weight was 350 g ± 250 g, and APGAR scores at 5 min were median of 9 ± 1. One out of eighteen patients experienced extension of the skin, perineal fascia, and bulbospongiosus muscle. Bleeding from the extension tearing of vaginal outlectomy was heavier than from uncomplicated vaginal outlectomy but negligible. Immediately postpartum, patients reported no moderate or severe perineal pain. At a 3-month postpartum, none of the subjects reported superficial or deep dyspareunia. Histology from the vaginal outlectomy specimens described the direct connection of the longitudinal vaginal smooth muscles to the hymeneal plate and compact connective tissues (like cartilage) of the hymeneal ring. Additionally, the histological examination showed the absence of the perineal skeletal muscle within the vaginal outlectomy specimens. The vaginal outlet is responsible for the most vital resistance force on a fetal head during delivery. Vaginal outlectomy widens the vaginal outlet sufficiently for a fetal vaginal birth with minimal bleeding and is easy to repair. No moderate-severe perineal pain or dyspareunia occurred in this study group. Vaginal outlectomy eliminates postpartum moderate-to-severe perineal pain and superficial dyspareunia. The posterior perineum creates no resistance force on the fetal head during vaginal delivery to warrant incision. [ABSTRACT FROM AUTHOR]

BackgroundAccurate identification of nulliparous women with failed spontaneous vaginal delivery (SVD) is crucial to minimize the hazards associated with obstetrical intervention (OI). While abnormal labor progression can be identified with intrapartum ultrasonography, labor-related complications may be unavoidable due to the limited time window left to the obstetrician. Antepartum ultrasound enables sufficient obstetric planning. However, there is typically a longer gap between ultrasound assessment and delivery that often lowers the prediction accuracy compared to intrapartum ultrasonography.ObjectiveIn this study, antepartum ultrasound assessment was included to each fetal ultrasound examination after 36 weeks of gestation until the onset of labor. We aim to establish a nomogram to predict the likelihood of failed SVD in nulliparous women using the last antepartum ultrasound findings before labor beginning.MethodsOf the 2,143 nulliparous women recruited, 1,373 were included in a training cohort and 770 in a validation cohort, based on their delivery date. Maternal and perinatal characteristics, as well as perinatal ultrasound parameters were collected. In the training cohort, the screened correlates of SVD failure were used to develop a nomogram for determining whether a nulliparous woman would experience SVD failure. This model was validated in both training and validation cohorts.ResultsSVD failure affected 217 nulliparous women (10.13%). In the training cohort, SVD failure was independently associated with BMI [odds ratio (OR) = 1.636], FHC (OR = 1.194), CL (OR = 1.398), and PCA (OR = 0.824) (all P

Stress urinary incontinence (SUI) is a common disorder in females, which significantly affects the quality of life in females. There are many consensus that describe the safety of childbearing after surgery for SUI, but still, a large proportion of surgeons worldwide recommend that women should wait to complete childbearing before pursuing surgical treatment for SUI. There is also some opinion that if patients conceive after surgical treatment for SUI, women should be delivered by cesarean section. Trans obturator tape (TOT) procedure is the most commonly performed mid-urethral sling (MUS) surgery for the treatment of SUI. We are reporting a case where a P2+0 woman underwent a TOT procedure where we used a cheaper alternative to a conventional TOT kit. She conceived and underwent spontaneous vaginal delivery after the procedure. She remained continent in the follow-up even after one year of vaginal delivery., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Abstract Background Retroperitoneal hematoma after vaginal delivery is rare but can lead to maternal morbidity and mortality. Diagnosis of this condition is challenging due to its complexity and its nonspecific signs and symptoms. To date, studies and case reports regarding retroperitoneal hematoma are few, particularly in low-income countries where risk factors for this condition may be more prevalent and the prognosis poorer. Case presentation We report the case of a 37-year-old multiparous african (Congolese) woman who presented to the emergency department of a large referral hospital in Bukavu, Democratic Republic of the Congo (DRC), 2 weeks after a spontaneous nontraumatic vaginal delivery. She had abdominal pain that began immediately after delivery and progressed throughout the postpartum period. The patient had anemia, hypotension, tachycardia, and a left costo-lumbar arch distorting the body shape on a soft and depressed abdomen. She had visited a private clinic on days 3 and 7 postpartum; however, signs and symptoms of retroperitoneal hematoma went unrecognized. Using abdominal ultrasound, we diagnosed an extensive hematoma in the retroperitoneal space from the left iliac fossa to the left flank. Laparotomy was performed to evacuate the hematoma, and the patient recovered. Conclusion Retroperitoneal hematoma following a nontraumatic vaginal delivery is an unusual situation in general obstetrical practice. The knowledge of this potentially life-threatening condition in resource-limited settings enables effective diagnosis and management by ultrasound and laparotomy.

Introduction and hypothesis: The objective of this study was to compare the impact of different modes of delivery, especially forceps delivery (FD), on pelvic floor muscles (PFMs) through vaginal surface electromyography (sEMG) in primiparous women at early (6–8 weeks) postpartum. Methods: A total of 1259 primiparous women with full-term singleton births were included in this cross-sectional study. Of these, 98 were delivered by forceps, 865 underwent spontaneous vaginal delivery (SD) and 296 underwent elective cesarean delivery (CD). Clinical demographic characteristics and vaginal sEMG variables of parturients 6–8 weeks after birth were collected and analyzed using SPSS software. One-way ANOVA with Bonferroni correction, Chi-square test or Student's t-test was used according to the variable type. Spearman correlation and binary logistic regression analyses were also used. P/α ≤ 0.05 was considered statistically significant. Results: Amplitude of fast and sustained contractions on sEMG in the FD group was significantly lower compared with the CD and SD groups. The sEMG amplitude of all contractions was significantly higher in the CD group compared with the FD and SD groups (P < 0.01). According to binary logistic regression analysis, mode of delivery was a major influencing factor in sEMG. Conclusions: An early postpartum sEMG test appears to be helpful for the assessment of PFM activity. Mode of delivery was a major influencing factor on sEMG. Forceps delivery significantly inversely influenced PFM activity. [ABSTRACT FROM AUTHOR]

Objective: The primary objective of this systematic review was to assess the association between spontaneous vaginal delivery and manual rotation during labor for occiput posterior or transverse positions. Our secondary objective was to assess maternal and neonatal outcomes.Data Sources: An electronic search of PubMed, EMBASE, ClinicalTrials.gov, and the Cochrane Register of Controlled Trials covered the period from January 2000 to September 2021, without language restrictions.Study Eligibility Criteria: The eligibility criteria included all randomized trials with singleton pregnancies at ≥37 weeks of gestation comparing the manual rotation groups with the control groups. The primary outcome was the rate of spontaneous vaginal delivery. Additional secondary outcomes were rate of occiput posterior position at delivery, operative vaginal delivery, cesarean delivery, postpartum hemorrhage, obstetrical anal sphincter injury, prolonged second stage of labor, shoulder dystocia, neonatal acidosis, and phototherapy. Subgroup analyses were performed according to types of position (occiput posterior or occiput transverse), techniques used (whole-hand or digital rotation), and parity (nulliparous or parous).Methods: The quality of each study was evaluated with the revised Cochrane risk-of-bias tool for randomized trials, known as RoB 2. The meta-analysis used random-effects models depending on their heterogeneity, and risks ratios were calculated for dichotomous outcomes.Results: Here, 7 of 384 studies met the inclusion criteria and were selected. They included 1402 women: 704 in the manual rotation groups and 698 in the control groups. Manual rotation was associated with a higher rate of spontaneous vaginal delivery: 64.9% vs 59.5% (risk ratio, 1.09; 95% confidence interval, 1.03-1.16; P=.005; 95% prediction interval, 0.90-1.32). This association was no longer significant after stratification by parity or technique used. Manual rotation was associated with spontaneous vaginal delivery only for the occiput posterior position (risk ratio, 1.08; 95% confidence interval, 1.01-1.15). Furthermore, it was associated with a reduction in occiput posterior or transverse positions at delivery (risk ratio, 0.64; 95% confidence interval, 0.48-0.87) and episiotomies (risk ratio, 0.84; 95% confidence interval, 0.71-0.98). The groups did not differ significantly for cesarean deliveries, operative vaginal deliveries, or neonatal outcomes.Conclusion: Manual rotation increased the rate of spontaneous vaginal delivery.

Objective  This study aimed to examine whether prenatal low-dose aspirin (LDA) therapy affects risk of cesarean versus vaginal delivery. Study Design  This study is a secondary analysis of the randomized clinical effects of aspirin in gestation and reproduction (EAGeR) trial. Women received 81-mg daily aspirin or placebo from preconception to 36 weeks of gestation. Mode of delivery and obstetric complications were abstracted from records. Log-binomial regression models estimated relative risk (RR) of cesarean versus vaginal delivery. Data were analyzed among the total preconception cohort, as well as restricted to women who had a live birth. Results  Among 1,228 women, 597 had a live birth. In the intent-to-treat analysis, preconception-initiated LDA was not associated with risk of cesarean (RR = 1.02; 95% confidence interval [CI]: 0.98–1.07) compared with placebo. Findings were similar in just women with a live birth and when accounting prior cesarean delivery and parity. Conclusion  Preconception-initiated daily LDA was not associated with mode of delivery among women with one to two prior losses. Key Points Aspirin was not associated with risk of cesarean section. Aspirin was not associated with mode of delivery. No increased risk of bleeding with use of aspirin. [ABSTRACT FROM AUTHOR]

Background: It is clinically challenging to determine when to intervene in the prolonged second stage. Although individualized prediction of spontaneous vaginal delivery is crucial to avoid maternal and neonatal complications associated with operative deliveries, the approach has not been fully established., Objective: We aimed to evaluate the predictability of spontaneous vaginal delivery using the difference in angle of progression between pushing and rest, delta angle of progression, to establish a novel method to predict spontaneous vaginal delivery during the prolonged second stage in nulliparous women with epidural anesthesia., Study Design: We retrospectively analyzed deliveries of nulliparous women with epidural anesthesia between September 2018 and October 2023. Women were included if their delta angle of progression during the second stage was available. Operative deliveries were defined as the cases that required forceps, vacuum, and cesarean deliveries due to labor arrest. Women requiring operative deliveries due to fetal and maternal concerns, or women with fetal occiput posterior presentation were excluded. The second stage was stratified into the prolonged second stage, the period after 3 hours in the second stage, and the normal second stage, the period from the beginning until the third hour of the second stage. The association of the delta angle of the progression measured during each stage with spontaneous vaginal delivery and operative deliveries was investigated. Furthermore, the predictability of spontaneous vaginal delivery was evaluated by combining the delta and rest angle of progression., Results: A total of 129 women were eligible for analysis. The delta angle of progression measured during the prolonged second stage and normal second stage were significantly larger in women who achieved spontaneous vaginal delivery compared to operative deliveries (p<.001 and p<.05, respectively). During the prolonged second stage, a cutoff of 18.8 derived from the receiver operative characteristic curves in the context of the delta angle of progression predicted the possibility of spontaneous vaginal delivery (sensitivity, 81.8%; specificity, 60.0%; AUC, 0.76). Combining the rest angle of progression (>140) and delta angle of progression (>18.8) also provided quantitative prediction of spontaneous vaginal delivery (sensitivity, 86.7%; specificity, 70.0%; AUC, 0.80)., Conclusion: The delta angle of progression alone or in combination with the rest angle of progression can be used to predict spontaneous vaginal delivery in the second stage in nulliparous women with epidural anesthesia. Quantitative analysis of the effect of pushing using the delta angle of progression provides an objective guide to assist with an assessment of labor dystocia in the prolonged second stage on an individualized basis, which may optimize labor management in the prolonged second stage by reducing neonatal and maternal complications related to unnecessary operative deliveries and prolonged second stage of labor., (Copyright © 2024 Elsevier Inc.

Background: Recently, ACOG released updated definitions for intraamniotic infection (IAI): maternal fever (≥38.0 °C) and ≥1 symptom (fetal tachycardia, maternal white blood cell count >15,000/mm3 or purulent discharge). Treatment was no longer recommended for women with fever <39.0 °C plus maternal tachycardia or fundal tenderness (previous criteria). The objective of this study was to compare postpartum infectious morbidity among women meeting previous criteria (but not the new IAI criteria) to women meeting new IAI criteria.Methods: Retrospective cohort of women delivering vaginally at a single academic center. Demographics, antepartum and intrapartum characteristics of women who met diagnostic criteria for chorioamnionitis (previous criteria) compared to those who met IAI criteria using bivariate statistics. The primary outcome was a composite of postpartum infection, including: endometritis, perineal infection, sepsis, urinary tract infection, pyelonephritis. Backward-stepwise elimination used to estimate odds of primary outcome.Results: Of 229 women who met previous IAI criteria, 51 (22.3%) did not meet new IAI criteria. Women no longer meeting IAI criteria were younger (25 versus 27 years, p = .02), more likely to have gestational hypertension (16.0 versus 3.4%, p < .01), and less likely to have third or fourth degree lacerations (2.0 versus 13.4%, p = .02). No difference in antibiotic receipt was observed. Postpartum infection occurred in 16/229 (7.0%) women overall; five (9.8%) in those not meeting new IAI criteria, and 11 (6.2%) meeting new IAI criteria. After adjusting for confounders, there was no difference in odds of postpartum infection (aOR 1.65, 95% CI 0.55-4.99).Conclusions/implications: Among women who met old ACOG criteria for IAI, but not the new criteria, postpartum infection occurred in nearly 10%. This number could be higher if these women were not treated with antibiotics. [ABSTRACT FROM AUTHOR]

Objective: To assess the effect of Episcissors-60 upon obstetric anal sphincter injuries (OASIS) reduction in nulliparous women.Study Design: Independent literature search for relevant studies was performed up to 30th May 2021 on five databases: Embase (OVID), MEDLINE (R) (OVID), CAB Abstracts (OVID), ClinicalTrials.gov, and Google Scholar. The primary outcome was to assess OASIS events prior and after Epi-60 implementation in clinical practice in natural births (NB), whilst secondary outcomes included overall operative vaginal delivery (OVD) %/spontaneous vaginal deliveries (SVD) % deliveries, episiotomy rates and operator satisfaction. All included studies (retrospective, prospective and time-series) examined the effect of Episcissors-60 implementation upon observed OASIS %.Results: A total of 14,027 nulliparous females were included in the meta-analysis. Overall, study heterogeneity was high at I2: 79% with collectively fair quality of studies, as assessed by the Newcastle-Ottawa scale. Overall, this analysis highlights significant differences of OASIS events that might suggest their implementation as standard practice [RD -0.02, 95% CI -0.03 to 0.00; P = 0.03].Conclusion: The present analysis highlights significant differences of OASIS events pre- and post- Epi-60, that may suggest Episcissors-60 implementation as standard practice. Nonetheless, to ensure data integrity, well reported observational studies and robust randomized controlled trials (RCTs) are required prior to introduction of Epi-60 as standard episiotomy technique in clinical practice.

Objective: In the prospective multicenter Genesis study, we developed a prediction model for Cesarean delivery (CD) in term nulliparous women. The objective of this secondary analysis was to determine whether the Genesis model has the potential to predict maternal and neonatal morbidity associated with vaginal delivery.Study Design: The national prospective Genesis trial recruited 2,336 nulliparous women with a vertex presentation between 39 + 0- and 40 + 6-weeks' gestation from seven tertiary centers. The prediction model used five parameters to assess the risk of CD: maternal age, maternal height, body mass index, fetal head circumference and fetal abdominal circumference. Simple and multiple logistic regression analyses were used to develop the Genesis model. The risk score calculated using this model were correlated with maternal and neonatal morbidity in women who delivered vaginally: postpartum hemorrhage (PPH), obstetric anal sphincter injury (OASI), shoulder dystocia, one- and five-minute Apgar score ≤ 7, neonatal intensive care (NICU) admission, cephalohematoma, fetal laceration, nerve palsy and fractures. The morbidities associated with spontaneous vaginal delivery were compared with those associated with operative vaginal delivery (OVD). The likelihood ratios for composite morbidity and the morbidity associated with OVD based on the Genesis risk scores were also calculated.Results: A total of 1,845 (79%) nulliparous women had a vaginal delivery. A trend of increasing intervention and morbidity was observed with increasing Genesis risk score, including OVD (p < 0.001), PPH (p < 0.008), NICU admission (p < 0.001), low Apgar score at one-minute (p < 0.001) and OASI (p = 0.009). The morbidity associated with OVD was significantly higher compared to spontaneous vaginal delivery, including NICU admission (p < 0.001), PPH (p = 0.022), birth injury (p < 0.001), shoulder dystocia (p = 0.002) and Apgar score of<7 at one-minute (p < 0.001). The positive likelihood ratios for composite outcomes (where the OVD was excluded) increases with increasing risk score from 1.005 at risk score of 5% to 2.507 for risk score of>50%.Conclusion: In women who ultimately achieved a vaginal birth, we have shown more maternal and neonatal morbidity in the setting of a Genesis nomogram-determined high-risk score for intrapartum CD. Therefore, the Genesis prediction tool also has the potential to predict a more morbid vaginal delivery. [ABSTRACT FROM AUTHOR]

Background: Retroperitoneal hematoma after vaginal delivery is rare but can lead to maternal morbidity and mortality. Diagnosis of this condition is challenging due to its complexity and its nonspecific signs and symptoms. To date, studies and case reports regarding retroperitoneal hematoma are few, particularly in low-income countries where risk factors for this condition may be more prevalent and the prognosis poorer.Case Presentation: We report the case of a 37-year-old multiparous african (Congolese) woman who presented to the emergency department of a large referral hospital in Bukavu, Democratic Republic of the Congo (DRC), 2 weeks after a spontaneous nontraumatic vaginal delivery. She had abdominal pain that began immediately after delivery and progressed throughout the postpartum period. The patient had anemia, hypotension, tachycardia, and a left costo-lumbar arch distorting the body shape on a soft and depressed abdomen. She had visited a private clinic on days 3 and 7 postpartum; however, signs and symptoms of retroperitoneal hematoma went unrecognized. Using abdominal ultrasound, we diagnosed an extensive hematoma in the retroperitoneal space from the left iliac fossa to the left flank. Laparotomy was performed to evacuate the hematoma, and the patient recovered.Conclusion: Retroperitoneal hematoma following a nontraumatic vaginal delivery is an unusual situation in general obstetrical practice. The knowledge of this potentially life-threatening condition in resource-limited settings enables effective diagnosis and management by ultrasound and laparotomy. [ABSTRACT FROM AUTHOR]

Background: Cesarean section (CS) is one of the most recurrently carried out surgical procedures in modern obstetrics. Worldwide, about 18.5 million CSs are conducted annually. Of this, 21–33% are performed in middle-and high-income countries. The effectiveness of the CS in preventing maternal and prenatal mortality and morbidity is medically justifiable. However, cesarean delivery without demanding obstetrical indications, by mere maternal request, may expose the child to several risks over benefits. Therefore, we aim to compare spontaneous vaginal delivery (vaginal delivery other than operative vaginal deliveries) and elective CS (CS before the onset of labor, but not including emergency CS) in decreasing the risk of neonatal respiratory morbidity.Objective: To compare the risk of neonatal respiratory morbidity in ECS and spontaneous vaginal delivery.Methods: A literature search was performed through visiting an electronic database (MEDLINE, PubMed, EMBASE, and CINAHL) and gray literature sources, including Google and Google Scholar, from January 2000 to May 2018. Original observational studies that reported the risk of neonatal respiratory morbidity in relation to mode of delivery conducted in the English language were identified and screened. Joanna Briggs Institute's quality assessment tool for observational studies was used to critically appraise the methodological quality of studies. Synthesis of individual studies was conducted using the Review Manager Software version 5.3 for Windows. Heterogeneity among studies was explored using the Cochran's Q-test and the I2 statistics. Pooled effect sizes in relative risk ratios with 95% confidence intervals were calculated. The flow of the study was prepared according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) checklist.Results: Sixteen studies were reviewed. A total of 327,272 neonates born by vaginal delivery and 55,246 born by ECS were included in this study. The risk of neonatal respiratory morbidity was increased by 95% in neonates delivered by ECS (RR = 1.95; 95% CI: 1.40–2.73) as compared with neonates born by spontaneous vaginal delivery.Conclusion: This study investigated the effect of mode of delivery on the respiratory morbidity without considering other risks and found that the ECS has a high risk of developing neonatal respiratory morbidities when compared to spontaneous vaginal delivery. So, we recommend discouraging unnecessary CS.registration: CRD42018104905.

Objective Guidelines for the management of chorioamnionitis include intrapartum antibiotics, while postpartum antibiotics after spontaneous vaginal delivery (SVD) are reserved high-risk women. Our objective is to describe the incidence of and risk factors for postpartum infection after SVD complicated by chorioamnionitis. Study Design This is a retrospective study of SVDs with clinically diagnosed chorioamnionitis at a single center. The primary outcome was a composite of postpartum infection. Women who developed the primary outcome were compared with those who did not using bivariate statistics. Regression models were developed to estimate adjusted odds of outcomes. Results In this cohort, 346 women underwent SVD complicated by chorioamnionitis. Of these, 23 (6.6%) developed postpartum infections (endometritis n = 7, urinary tract infection/pyelonephritis n = 6, sepsis n = 4, and perineal wound infection n = 6). Receipt of antibiotics intra- or postpartum did not differ between groups, but women with postpartum infections were more likely to deliver prior to 32 weeks (17.4 vs. 4.9%, p = 0.04). When controlling for antibiotic use, delivery at

Subtle but demonstrable movements in the expectant mother's pelvis occur during vaginal delivery in all the pelvic joints and anatomical planes of the body (sagittal, frontal, and transverse). The purpose of these movements is to gradually expand the space in the lesser pelvis via widening of the individual pelvic planes so that the newborn's head can enter the pelvic inlet, safely pass through the narrow planes of the pelvis, and through the pelvic outlet. From the point of view of biomechanics, these movements are described in literature as counternutation and nutation of the sacrum and iliac bone. The counternutation of the sacrum helps to expand the plane of the pelvic inlet. The nutation of the sacrum assists in expanding the plane of the pelvic width, height, and outlet. These physiological movements are affected by the body constitution, the state of the myofascial and skeletal systems of the mother, and furthermore, by hormonal disjunction of the connections in the expectant mother's pelvis together with the progress of the delivery mechanism itself. The main factor that determines the range of movement in the individual joints, and therefore adequate expansion of the individual pelvic planes, is the position of the mother during delivery. Engagement of active movements of the mother together with application of passive stretching of the soft tissues in the lower lumbar area and in the hip joints are both needed for maximum expansion of the individual pelvic planes and utilization of the maximum useful capacity of the mother's pelvis during delivery. These movements help invoke the abduction forces on muscles, tendons, and ligaments in the pelvis that lead to the optimum setting of the joints during which delivery movements happen. The specific movements in the pelvic joints predetermine whether nutation or counternutation is possible, and therefore if the newborn's head can progress to the pelvic inlet or pass through the narrow and wide pelvic planes, and the pelvic outlet. The knowledge of these biomechanical principles and movements in the pelvis during delivery enables obstetricians and midwives to understand how the movements in the hip joints of the expectant mother can positively impact the spatial ratios in the lesser pelvis, and how to support further progress in the event of non-progressive labour.

Key Message: Listening to music during labor increases the likelihood that primiparas will have a spontaneous vaginal delivery.Purpose: To examine the effects of exposure to music during labor on the mode of delivery and parturients' stress levels.Methods: This prospective, interventional study included 124 low-risk women who were recruited during latent phase of their first labor after epidural anesthesia. Patients were grouped according to their preference to receive music intervention or not. The music intervention included two subgroups: soft classical music and rhythmic music. We evaluated cortisol levels in saliva as a surrogate for stress level and State-Trait Personality Inventory at enrollment and 1-3 h later in all women who were still in labor. Delivery and perinatal outcomes were collected from electronic medical records. Correlations between the music intervention and maternal and perinatal outcomes were evaluated.Results: Spontaneous vaginal delivery was significantly more frequent among women listening to music compared to the non-music group (P = 0.035). A trend towards lower rates of cesarean delivery was noted in the music group (P = 0.08), with no difference in instrumental vaginal delivery rates. Stress levels, as measured by questionnaires and by cortisol levels, blood pressure and pulse rate, remained similar throughout the study. No differences were noted between the different genres of music when examining obstetric and perinatal outcomes and stress levels.Conclusion: Listening to music during labor, improves the likelihood of primiparas to have a vaginal delivery regardless of stress level. As this treatment is simple, easy, and harmless to administer, we suggest it may be offered to all patients during labor. [ABSTRACT FROM AUTHOR]

Objective: To compare the frequency of third and fourth degree perineal tears with and without episiotomy in mothers undergoing vaginal delivery. Study Design: randomized controlled trail Place and Duration: Labour Ward Emergency of Obstetrcics and Gynaecology Department of Nishtar Hospital, Multan, from 1st January to 31st December 2017. Methodology: Total 1000 patients divided equally in two groups, episiotomy (group-A) and no-episiotomy (group-B) fulfilling the inclusion criteria of full term pregnancy, full cervical dilatation,well engaged fetal head and maternal urge to push were included in the study. The patients with history of surgically treated fourth degree perineal tears were excluded. The maternal outcome in terms of frequency of episiotomy, instrumental delivery and perineal trauma including third and fourth degree tears were observed alongwith other demographic variables. Results: Episiotomy was observed as 26.6% and 7.8% for the episiotomy and no -episiotomy groups respectively. The outcomes of third degree and fourth degree was observed as 1% and 0.6% respectively in episiotomy group. The outcomes of third degree and fourth degree was observed as 1% and 0.8% respectively in no-episiotomy group. The coefficients were statistically significant in primigravida and mode of delivery (p=0.000) being more common with forceps. Episiotomy has insignificant relationship with severe perineal trauma. Conclusion: There is no difference in frequency of severe perineal trauma with and without episiotomy approach in women undergoing vaginal delivery. [ABSTRACT FROM AUTHOR]

This article describes a large-scale scenario designed to test the capabilities of a US biocontainment unit to manage a pregnant woman infected with a high-consequence pathogen, and to care for a newborn following labor and spontaneous vaginal delivery. We created and executed a multidisciplinary functional exercise with simulation to test the ability of the Johns Hopkins Hospital biocontainment unit (BCU) to manage a pregnant patient in labor with an unknown respiratory illness and to deliver and stabilize her neonate. The BCU Exercise and Drill Committee established drill objectives and executed the exercise in partnership with the Johns Hopkins Simulation Center in accordance with Homeland Security and Exercise Program guidelines. Exercise objectives were assessed by after-action reporting and objective measurements to detect contamination, using a fluorescent marker to simulate biohazardous fluids that would be encountered in a typical labor scenario. The immediate objectives of the drill were accomplished, with stabilization of the mother and successful delivery and resuscitation of her newborn. There was no evidence of contamination when drill participants were inspected under ultraviolet light at the end of the exercise. Simulation optimizes teamwork, communication, and safety, which are integral to the multidisciplinary care of the maternal-fetal unit infected, or at risk of infection, with a high-consequence pathogen. Lessons learned from this drill regarding patient transportation, safety, and obstetric and neonatal considerations will inform future exercises and protocols and will assist other centers in preparing to care for pregnant patients under containment conditions. This article describes a large-scale scenario designed to test the capabilities of a US biocontainment unit to manage a pregnant woman infected with a high-consequence pathogen, and to care for a newborn following labor and spontaneous vaginal delivery.

During the past decade, there has been a consistent rise in the number of twin births and the number of overall cesarean sections (CS) worldwide. This is owed to a variety of social, economic, educational, and scientific factors. More women are opting to advance their professional careers and gain financial stability before having children. Although this approach is understandable, a new set of challenges are faced as a result, the most important of which has been infertility due to advanced maternal age and the subsequent use of assisted fertility treatments, which have been noted to cause multiple gestations. Twin gestations are considered high-risk pregnancies and are associated with an amplitude of potential complications. Arguably, the biggest decision an obstetrician must make when dealing with this population is choosing the most appropriate mode of delivery. Given the lack of clear guidance pertaining to twin deliveries, CSs may often be perceived as safer and are often preferred over vaginal deliveries (VD). In this narrative review, we aimed to compare the outcomes of different delivery methods (CS versus VD) to investigate whether CS is truly superior to VD. Data were collected from the past two decades and analyzed based on the neonatal and maternal outcomes for each delivery mode. Our results indicate that planned VD is just as safe as CS, if not superior, in most uncomplicated twin pregnancies. Thus, it is best to advise and encourage healthy expecting twin carriers to undergo VD and explore any hesitations or fears they might have. Furthermore, a detailed guideline regarding twin delivery is essential to establish and better navigate twin deliveries, lower the rate of unnecessary CSs, and reduce overall twin gestation morbidity and mortality., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Abraham et al.)

Vulval lichen sclerosus (VLS) is a chronic inflammatory skin condition affecting the anogenital area in women. Serious long‐term consequences of VLS include the risk of developing squamous cell carcinoma of the vulva as well as of scarring and alteration of vulval architecture. The treatment of choice for genital lichen sclerosus in females is potent to very potent topical corticosteroids. There are few published data on the course of VLS in pregnancy. We present our experience of managing 33 pregnancies in 29 women with VLS. [ABSTRACT FROM AUTHOR]

Objective The objective of this study was to assess the association between the angle of progression (AoP) measured by transperineal ultrasound and mode of delivery and duration of the second stage. Study Design This is a prospective observational study of nulliparous women with a singleton gestation at term in which serial transperineal ultrasound examinations were obtained during the second stage of labor. Multivariable logistic regression and adjusted survival models were used for the analysis. Results A total of 137 patients were included in the analysis and median AoP for the study group was 153 degrees. The adjusted odds ratio (aOR) of requiring an operative delivery was 2.6 times higher for those patients who had an AoP < 153 degrees and the aOR of requiring a cesarean delivery was almost six times higher when compared with those patients who had an AoP ≥ 153 degrees (95% confidence interval [CI]: 1.0, 6.2; p = 0.04; aOR: 5.8, 95% CI: 1.2-28.3; p = 0.03, respectively). Those patients with an AoP < 153 degrees were at a higher hazard of staying pregnant longer (adjusted hazard ratio: 1.8, 95% CI: 1.2-2.8, p = 0.005). Conclusion The AoP has the potential to predict spontaneous vaginal delivery and the duration of the second stage of labor which may be useful in counseling patients and managing their labor.

Background: Membrane sweeping (MS) could increase the likelihood of spontaneous labor within 48 h. However, the rationale for performing routinely an intervention with the potential to induce labor in women with an uneventful pregnancy at 38 weeks of gestation is, at least, questionable. We conducted a meta-analysis of randomized controlled trial (RCT) studies to assess evaluated the effect of MS added to formal induction method on the spontaneous vaginal delivery, compared with formal induction alone.Methods: PubMed, Embase, Cochrane Library databases, Web of Science, and Clinical Trials were searched from their inception to March 8, 2017. We estimate summarized relative risk (RR) and 95% confidence intervals (CIs) for dichotomous outcomes. The primary outcome was vaginal delivery, and second outcomes (side effects of MS) included meconium-stained liquor, admission to the neonatal unit, instrumental delivery.Results: Four RCTs with a total of 1377 participants were identified. The summary RR in the overall group was 1.12 (95% CI 1.05-1.18), with moderate heterogeneity (P = 0.22, I2 = 33%). The summary RR in the nulliparas' subgroup was 1.32 (95% CI 1.18-1.48), with no heterogeneity (P = 0.79, I2 = 0%). MS did not increase the risk of side effects.Conclusions: MS added to formal induction significantly increased vaginal delivery rates, especially in nulliparas compared with formal induction alone. Notably, there are no obvious side effects of MS. Meanwhile, more RCTs studies are needed to investigate the side effects of MS on instrumental delivery, postpartum hemorrhage, and cervical laceration. [ABSTRACT FROM AUTHOR]

Aim This descriptive study aimed to explore the associations between fear of childbirth, acceptance of pregnancy and identification with the motherhood role among primipara women. Background Women who have difficulty accepting their pregnancy have a harder time adapting to pregnancy and motherhood and experience more fears related to childbirth. The number of studies conducted on this topic is limited. Methods This study involved 310 pregnant women admitted to a public hospital in Istanbul between January and June of 2013. A participant identification form, the Prenatal Self-Evaluation Questionnaire and the Wijma Delivery Expectancy/Experience Questionnaire Version A were used for data collection. Results Pregnant women participating in the study experienced moderate levels fear of childbirth. Pregnant women who requested caesarean section experienced more intense fear of childbirth. Fear of childbirth scores had significant but weak correlations with acceptance of pregnancy and identification with the motherhood role. Conclusion The findings showed that acceptance of pregnancy and identification with the motherhood role are weakly associated with fear of childbirth. Implications for nursing and health policy The results from this study can be used to help: increase awareness among health professionals (doctors, nurses, midwives) in antenatal care services about a mother's adaptation to pregnancy and the negative effects of fear of childbirth; direct future research examining factors affecting adaptation to pregnancy and fear of childbirth; establish routine assessments for adaptation to pregnancy and fear of childbirth; provide professional support for women with difficulties adapting to pregnancy and with fear of childbirth; result in reduced complications from invasive methods such as caesarean section due to less requests for these procedures; and promote the health of mothers and babies.

Background: Intrapartum head circumference is an integral part of sonographic models and important for the purpose of fetal weight estimation as well as in cases which abnormal fetal head growth is suspected, it is considered the interface between maternal pelvis and fetus. Aim: This study aims to assess the accuracy of fetal head circumference compared to expected fetal weight as a predictor of spontaneous vaginal delivery. Methods: A prospective observational study was conducted on 996 women in active stage of labor admitted to Labor ward of Ain Shams University Maternity Hospital and Labor ward in Manshiet El Bakry general hospital. Results large head circumference (odds ratio, 2.8; 95% CI, 1.37-5.73; p-value; .005 was independent predictors for cesarean delivery, and no significant difference on mode of delivery between different expected fetal weight. Conclusion: A large head circumference is more strongly associated with unplanned caesarian section than high expected fetal weight. [ABSTRACT FROM AUTHOR]

Objectives: To determine frequency of different mode of deliveries and associated maternal complications in primigravidas in tertiary care setup. Study Design: Case series study. Setting: Department of Obstetrics and Gynaecology (Liaquat University Hospital) Hyderabad, Sindh, Pakistan. Period: 6 months from Jan 2009 till June 2009. Methodology: All the primigravidas underwent delivery by any means i-e emergency\elective caesarean section or spontaneous vaginal delivery\instrumental vaginal delivery and developed postpartum complications up till 7 days after delivery were included. Data was analyzed on pre- designed profoma and was analyzed through software program SPSS version 10. Results: In this study most frequent mode of delivery were found to be spontaneous vaginal delivery 46(36.8%) and emergency caesarean section 29(23.2%) while forceps 8.8%, vacuum 20% and elective caesarean section 1.2%. Complications associated with mode of deliveries included postpartum hemorrhage were reported to be 51.2%, abdominal wound infection 11.2%, perineal wound infection 17.6%, retained products of conception 28% and puerperal sepsis 16.8%. Conclusion: Deliveries in our setup are mostly conducted by dais (birth attendants) without any aseptic measures and without assessing the abnormalities that will leads to emergency caesarean section or instrumental vaginal deliveries and in the consequence of these entire patients develop postpartum complications.

Objective: To identify risk factors for mediolateral episiotomy, and evaluate the risk of obstetrical anal sphincter injury (OASI) among women with an episiotomy.Methods: A retrospective cohort study of all singletons vaginal deliveries at term between 2007 and 2014. Spontaneous and operative vaginal deliveries were compared separately, as well as nulliparous and multiparous women.Results: Overall, 41,347 women were included in the spontaneous vaginal delivery group: 12,585 (30.4%) nulliparous and 28,762 (69.6%) multiparous women. Risk factors for episiotomy (nulliparous) were maternal age (aOR 0.98), gestational age (GA, aOR 1.07), regional analgesia (RA, aOR 1.18), labor induction (aOR 1.17), meconium (aOR 1.37) and birth weight (BW, aOR 1.04). Episiotomy was associated with PPH (aOR 1.49). Among multiparous, risk factors were maternal age (aOR 1.04), previous vaginal delivery (aOR 0.38), GA (aOR 1.06), RA (aOR 1.22), meconium (aOR 1.22) and BW (aOR 1.05). Episiotomy was associated with 3rd degree perineal tear (aOR 2.26, 95% CI 1.03-4.97). Only birth weight (nulliparous) and previous vaginal deliveries (multiparous) were contributors for episiotomy in the OVD group.Conclusion: Several risk factors for mediolateral episiotomy exist. Episiotomy does not protect nulliparous women, and may be associated with an increased risk for multiparous, for OASI. Therefore, the practice of routine episiotomy should be abandoned, and the practice of selective episiotomy reconsidered. [ABSTRACT FROM AUTHOR]
