Bachar G, Farago N, Weissman A, Khatib N, Ginsberg Y, Vitner D, Beloosesky R, Weiner Z, Zipori Y. Interpregnancy interval after vacuum delivery and subsequent perinatal outcomes. Int J Gynaecol Obstet 2024. [PMID: 38881216 DOI: 10.1002/ijgo.15731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 05/03/2024] [Accepted: 06/01/2024] [Indexed: 06/18/2024]
Abstract
OBJECTIVE To evaluate whether a short interpregnancy interval (IPI) after vacuum extraction (VE), poses similar perinatal risks in a subsequent pregnancy. METHODS This was a retrospective, single-center cohort study between 2011 and 2021. Nulliparous women with term, singleton VE deliveries and with known pregnancy outcomes in their subsequent pregnancy were eligible for inclusion in the study. Each woman was allocated into one of two groups based on the IPI, <18 months and between 18 and 60 months. The primary outcome was the risk of spontaneous preterm birth (PTB) <37 weeks in the consecutive birth. RESULTS We included 1094 pregnancies: 212 (19.4%) with IPI <18 months and 882 (80.6%) with IPI between 18 and 60 months following the previous VE delivery. The VE characteristics were comparable between the groups. Young maternal age was a risk factor for a short IPI (28.0 ± 4.8 vs 30.3 ± 4 years, P < 0.01). Spontaneous PTB <37 weeks was significantly higher in the IPI <18 months group with 18-60 months (7.1% vs 2.6%, P = 0.002). Polynomial regression analysis also confirmed a significantly increased risk of preterm birth <37 weeks (P < 0.01). Short IPI <18 months was also associated with an increase in the risk of low birthweight <2500 g (6.1% vs 2.8%, P = 0.02) and admission to the neonatal intensive care unit (6.1% vs 2.6%, P = 0.013). The incidence of recurrent VE, albeit significant (2.3% vs 4.9%, P = 0.049), was low in both groups. No differences were noted in any of the other secondary outcomes. CONCLUSION Short IPI (<18 months) following term VE delivery is associated with higher neonatal risks, particularly PTB, in the subsequent pregnancy. These findings are particularly important when counseling women planning an optimal IPI.

Wang Y, Niu Y, Xu Z, Yan X, Li J, Xu H. Association of the Kiwi OmniCup system with maternal and neonatal morbidity: A retrospective cohort study. Int J Gynaecol Obstet 2024; 164:699-707. [PMID: 37587733 DOI: 10.1002/ijgo.15037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 07/11/2023] [Accepted: 07/25/2023] [Indexed: 08/18/2023]
Abstract
OBJECTIVE To discuss the effect of the Kiwi OmniCup system on reducing adverse maternal and neonatal outcomes and provide a reference for assisted vaginal delivery methods. METHODS Women who gave birth to singleton term neonates in a cephalic presentation and underwent assisted vaginal delivery from 2017 to 2021 were eligible for inclusion in the study; they were divided into a Kiwi OmniCup system group and a forceps group. Binary logistic regression analysis was used to observe and compare maternal and neonatal outcomes. The primary outcomes were severe maternal and neonatal morbidity. Severe maternal morbidity was defined as the occurrence of at least one of the following outcomes: third- or fourth-degree perineal lacerations, refractory postpartum hemorrhage, thrombotic events, amniotic fluid embolism, admission to the intensive care unit, and maternal death. Severe neonatal morbidity was defined as the occurrence of at least one of the following outcomes: neonatal asphyxia requiring resuscitation or intubation, neonatal head and face injuries, neonatal fracture, and admission to the neonatal intensive care unit for longer than 24 h. RESULTS The rate of severe neonatal morbidity in the forceps group was significantly higher than that in the Kiwi OmniCup system group, the differences between the two groups were significant (27.2% vs. 42.3%, P < 0.001), and there was no significant difference in the rate of severe maternal morbidity between the two groups (30% vs. 30%, P > 0.05). Binary logistic regression analysis showed that Kiwi OmniCup system-assisted delivery reduced severe neonatal morbidity (adjusted odds ratio 0.49; 95% confidence interval 0.33-0.73) and did not increase severe maternal morbidity compared with forceps-assisted delivery. CONCLUSION The Kiwi OmniCup system, which can reduce the incidence of severe neonatal morbidity without increasing the incidence of serious adverse maternal outcomes, is worthy of clinical promotion.

Unscarred uterine rupture with catastrophic hemorrhage immediately after vaginal delivery: diagnosis and management of six consecutive cases. J Matern Fetal Neonatal Med 2023; 36:2243366. [PMID: 37586890 DOI: 10.1080/14767058.2023.2243366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 07/26/2023] [Accepted: 07/27/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND To describe and explore the risk factors, clinical presentations, timely diagnostic approaches, and management in patients experiencing unscarred uterine rupture with catastrophic hemorrhage. METHODS We retrospectively analyzed clinical and imaging data from women who encountered postpartum hemorrhage (PPH) and were diagnosed with unscarred uterine rupture within a three-year timeframe (2018-2020). The data were extracted from medical records obtained from a multi-hospital 24-hour emergency PPH transfer system. RESULTS Six patients were identified as having unscarred uterine rupture after vaginal delivery. All six women were para 2, with four of them undergoing vacuum-assisted delivery. One patient experienced out-of-hospital cardiac arrest (OHCA), while five patients presented with hypovolemic shock. Abdominopelvic ultrasound revealed a boggy lower uterine segment. Initially, five patients underwent transarterial embolization (TAE) of the internal iliac arteries in an attempt to achieve hemostasis, but this approach proved unsuccessful. Abdominopelvic computed tomography (CT) confirmed the diagnosis of ruptured uterus by demonstrating disrupted myometrium and hemoperitoneum. Immediate exploratory laparotomy followed by life-saving hysterectomy was performed in all cases. The median estimated total blood loss was 2725 mL ± 900 mL (ranging from 1600 mL to 7100 mL). Lower segment lacerations were observed in all patients, with more extensive uterine damage noted in those who underwent vacuum extraction. The length of hospital stay varied between 9 and 38 days. CONCLUSION Instrument-assisted obstetric delivery is a possible contributing factor to unscarred uterine rupture in our study. In specific cases, the use of abdominopelvic CT prior to initiating transarterial embolization (TAE) offers valuable information to complement ultrasound findings. This comprehensive approach helps in accurately identifying the underlying cause of intractable postpartum hemorrhage (PPH). Immediate conversion to laparotomy is essential to explore the intra-abdominal factors causing PPH that cannot be controlled by TAE. The rational etiologies of uterine rupture must be clarified while generating practical guideline in the future.

Sci Rep 2023; 13:2658.

Abstract
Our aim was to identify factors associated with shoulder dystocia following an attempted operative vaginal delivery (aOVD) in a prospective cohort study and to evaluate whether these factors can be used to accurately predict shoulder dystocia by building a score of shoulder dystocia risk. This was a planned secondary analysis of a prospective cohort study of deliveries with aOVD at term from 2008-2013. Cases were defined as women with shoulder dystocia following an aOVD defined as a delivery that requires additional obstetric maneuvers following failure of gentle downward traction on the fetal head to effect delivery of the shoulders. Multivariate logistic regression analyses were performed to determine risk factors for shoulder dystocia. Shoulder dystocia occurred in 57 (2.7%) of the 2118 women included. In the whole cohort, women with shoulder dystocia more often had a history of shoulder dystocia (3.5% vs. 0.2%, p = 0.01), and there was a significant interaction between aOVD and gestational age and the duration of the second stage of labor: women with shoulder dystocia more often had a gestational age > 40 weeks and a second stage of labor longer than 3 h specifically for midpelvic aOVD. In multivariable analysis, a history of shoulder dystocia was the only factor independently associated with shoulder dystocia following aOVD (aOR 27.00, 95% CI 4.10-178.00). The AUC for the receiver operating characteristic curve generated using a multivariate model with term interaction with head station was 0.70 (95% CI 0.62-0.77). The model failed to accurately predict shoulder dystocia.

Abstract
BACKGROUND During the second stage of labor, in case of a need for a fetal extraction at midcavity, the choice of attempting the procedure between operative vaginal delivery and cesarean delivery is difficult. Moreover, guidelines on this subject are not clear. OBJECTIVE This study aimed to identify antenatal and intrapartum parameters associated with a failed midcavity vacuum-assisted delivery and its association with maternal and neonatal adverse outcomes. STUDY DESIGN This was a single-center, retrospective, cohort study conducted at a tertiary maternity hospital in France from January 2010 to December 2020. Women with singleton pregnancies under epidural analgesia with nonanomalous cephalic presenting fetuses and gestational ages at ≥37 weeks of gestation, who were submitted to midcavity vacuum-assisted delivery, were included. Following the American College of Obstetricians and Gynecologists definition, midcavity was defined as the presenting part of the fetus (ie, the fetal head) found at stations 0 and +1. For research purposes, all patients were submitted to transperineal ultrasound to evaluate the head-to-perineum distance, however, this measurement did not affect the decision to perform a midcavity vacuum-assisted delivery. The primary outcome of the study was failed midcavity vacuum-assisted delivery leading to cesarean delivery or the use of a different instrument to achieve vaginal delivery. RESULTS Overall, 951 cases of midcavity vacuum-assisted delivery were included in this study. Failed midcavity vacuum-assisted delivery occurred in 242 patients (25.4%). Factors independently associated with failed midcavity vacuum-assisted delivery included maternal height (adjusted odds ratio, 0.96; 95% confidence interval, 0.94-0.99; P=.002), duration of the active phase of the first stage of labor (adjusted odds ratio, 1.11; 95% confidence interval, 1.05-1.17; P<.001), nonocciput anterior fetal head position (adjusted odds ratio, 1.47; 95% confidence interval, 1.06-2.04; P=.02), z score of the head-to-perineum distance (adjusted odds ratio, 1.23; 95% confidence interval, 1.05-1.43; P=.01), and birthweight of >4000 g (adjusted odds ratio, 2.04; 95% confidence interval, 1.28-3.26; P=.003). Women submitted to a failed midcavity vacuum-assisted delivery were more likely to have a major postpartum hemorrhage (7.1% vs 2.0%; P<.001), whereas neonates were more likely to have an umbilical artery pH of <7.1 (30.5% vs 19.8%; P=.001), be admitted to the neonatal intensive care unit (9.6% vs 4.7%; P=.005), and have a severe caput succedaneum (14.9% vs 0.7%; P<.001). Subgroup analysis on all patients with a fetal head station of 0 found that the head-to-perineum distance was the only independent variable associated with failed midcavity vacuum-assisted delivery (adjusted odds ratio, 1.66; 95% confidence interval, 1.29-2.12; P<.001). The area under the receiving operating characteristic curve of the head-to-perineum distance in this subgroup population was 0.67 (95% confidence interval, 0.60-0.73; P<.001), and the optimal cutoff point of the head-to-perineum distance measurement discriminating between failed and successful midcavity vacuum-assisted deliveries was 55 mm. It was associated with a 0.90 (95% confidence interval, 0.83-0.95) sensitivity, 0.19 (95% confidence interval, 0.14-0.25) specificity, 0.36 (95% confidence interval, 0.30-0.42) positive predictive value, and 0.80 (95% confidence interval, 0.66-0.90) negative predictive value. CONCLUSION Study data showed that a high fetal head station, measured using the head-to-perineum distance, and a nonocciput anterior position of the fetal head are independently associated with failed midcavity vacuum-assisted delivery. The result supported the systematic assessment of the sonographic head station and position before performing a midcavity vacuum-assisted delivery.

Abstract
OBJECTIVE To compare outcomes of women with low-lying placenta by planned mode of delivery and distance from the internal os distance. METHODS Six tertiary maternity hospitals in France participated in this retrospective multicenter study of births from 2007-2012. Women with low-lying placenta , defined as an internal os distance of 20 mm or less, who gave birth after 35 weeks of gestation were included and classified in the planned trial-of-labor or elective cesarean delivery groups. The primary endpoint was severe postpartum hemorrhage (PPH) defined as blood loss exceeding 1,000 mL. Secondary outcomes were composite variables of severe maternal and neonatal morbidity. We used multivariable logistic regression and propensity scores to compare outcomes by planned mode of delivery. RESULTS Among 128,233 births during the study period, 171 (0.13%) women had low-lying placenta: 70 (40.9%) in the trial-of-labor group and 101 (59.1%) who underwent elective cesarean delivery. The rate of severe PPH was 22.9% (16/70, 95% CI 13.7-34.4) for the trial-of-labor group and 23.0% (23/101, 95% CI 15.2-32.5) for the cesarean delivery group ( P =.9); severe maternal and neonatal morbidity rates were likewise similar (2.9% vs 2.0% [ P =.7] and 12.9% vs 9.9% [ P =.5], respectively). Trial-of-labor was not significantly associated with a higher rate of severe PPH after multivariable logistic regression and propensity score-weighted analysis (adjusted odds ratio [aOR] 1.42, 95% CI 0.62-3.24 [ P =.4]; and aOR 1.34, 95% CI 0.53-3.38 [ P =.5], respectively). The vaginal delivery rate in the trial-of-labor group was 50.0% (19/38) in those with an internal os distance of 11-20 mm and 18.5% (5/27) in those with a distance of 1-10 mm. CONCLUSION Our results support a policy of offering a trial of labor to women with low-lying placenta after 35 weeks of gestation and an internal os distance of 11-20 mm. An internal os distance of 1-10 mm reduces the likelihood of vaginal birth considerably, compared with 11-20 mm, but without increasing the incidence of severe PPH or severe maternal morbidity.

Abstract
INTRODUCTION During the second stage of labor, vacuum-assisted delivery is an alternative to forceps delivery and emergency cesarean section. Extensive research concerning perinatal outcomes has indicated that the risk of complications, although rare, is higher than with a spontaneous vaginal delivery. An important factor related to perinatal outcomes is the traction force applied. Our research group previously developed a digital extraction handle, the Vacuum Intelligent Handle-3 (VIH3), that measures and records traction force. The objective of this study was to compare traction force profiles in children with and without severe perinatal outcomes delivered with the digital handle. A secondary aim was to establish a safe force limit. MATERIAL AND METHODS This was an observational case-control study at the delivery ward at Karolinska University Hospital, Sweden. In total, 573 children delivered with the digital handle between 2012 and 2018 were included. Cases were defined as a composite of severe perinatal outcomes, including subgaleal hematoma, intracranial hemorrhage, hypoxic ischemic encephalopathy 1-3, seizures or death. The cases in the cohort were matched 1:3 based on five matching variables. Traction profiles were analyzed using the MATLAB® software and conditional logistic regression. RESULTS The incidence of severe perinatal outcomes was 2.3%. The 13 cases were matched with three controls each (n = 39). A statistically significant increased odds for higher total traction forces was seen in the case group (odds ratio [OR] 1.004; 95% confidence interval [CI] 1.001-1.007) and for the peak force (OR 1.022; 95% CI 1.004-1.041). Several procedure-related parameters were significantly increased in the case group. As expected, some neonatal characteristics also differed significantly. An upper force limit of 343 Newton minutes (Nmin) revealed an 86% reduction in severe perinatal outcomes (adjusted OR 0.14; 95% CI 0.04-0.5). CONCLUSIONS Children with severe perinatal outcomes had traction force profiles with significantly higher forces. The odds for severe perinatal outcomes increased for every increase in Nmin and Newton used during the extraction procedure. A calculated total force level of 343 Nmin is suggested as an upper safety limit, but this must be tested prospectively to provide validity.

Abstract
OBJECTIVES To compare the incidence of cephalic marks in newborns exposed to operative vaginal delivery and those who are not. We examined the factors associated with alterations in neonatal well-being and with cephalic mark occurrence. METHODS Prospective study involving singleton term newborns delivered in a cephalic presentation. Newborns in the operative group were matched with newborns born on the same day without instruments required. A cephalic mark was defined as any mark or edema on the newborn's skin between 12 and 72 hours of life. Neonatal well-being was assessed by analgesic consumption, neonatal discomfort (EDIN score of 1 or more), and prolonged hospitalization (4 days or more). We compared the operative and spontaneous groups and determined the relative risk (RR) for cephalic marks. We investigated the factors associated with alterations in neonatal well-being and factors associated with cephalic mark occurrence in the case of operative delivery using multivariate logistic regression analysis. RESULTS A total of 135 newborns were included in each group. The incidence of cephalic marks was higher in the operative group (RR = 13.3 [6.0-29.5]). In case of operative delivery, cephalic marks were associated with neonatal discomfort (adjusted odds ratios [aOR] = 8.2 [2.2-30.6]) and analgesic consumption (aOR = 3.0 [1.2-7.1]). The number of cephalic marks was higher in cases with sequential use of vacuum and forceps (aOR = 3.5 [1.1-11.7]) and forceps only deliveries (aOR = 3.0 [1.1-8.1]) relative to vacuum only deliveries. CONCLUSIONS Operative delivery increases the risk of neonatal cephalic marks, which can negatively affect neonatal well-being.

Abstract
Glanzmann thrombasthenia (GT) is a rare inherited platelet function disorder caused by a quantitative and/or qualitative defect of the αIIbβ3 integrin. Pregnancy and delivery is a recognized risk period for bleeding in women with GT. The newborn may also be affected by fetal and neonatal immune thrombocytopenia induced by the transplacental passage of maternal anti-αIIbβ3 antibodies, which can lead to severe hemorrhage and fetal loss. Pregnancy in GT women thus requires a multidisciplinary approach, including prepregnancy counseling, and a treatment plan for delivery for both the mother and child. In this article, we summarize the current knowledge on pregnancy in women with GT and describe how we manage this severe platelet disorder in our clinical practice.

PLoS One 2022; 17:e0262292. [PMID: 35061804 PMCID: PMC8782477 DOI: 10.1371/journal.pone.0262292] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 12/20/2021] [Indexed: 11/19/2022] Open
Abstract
Background The purposes of successful induction of labor (IOL) are to shorten the time for IOL to delivery, increase the vaginal delivery rate, and reduce the rate of maternal and neonatal morbidity. In cases of unfavorable cervix (Bishop score <6), cervical ripening is advised to improve vaginal delivery rate. It may be initiated by mechanical (double balloon catheter (DBC), synthetic osmotic dilator) or pharmacologic (prostaglandins) methods, and the problem is complex due to the multitude of cervical ripening methods. We are constantly looking for the optimal protocol of cervical ripening for each woman. The present study aims to elucidate whether cervical ripening method is associated with increase rate of vaginal delivery, good women’s experience and unaltered long-term quality of life after cervical ripening at term regarding maternal and obstetric characteristics. Methods and design The MATUCOL study is a monocentric, prospective, observational study of all consecutive women who required cervical ripening (Bishop score <6) using different methods (DBC, vaginal dinoprostone, oral misoprostol) with a live fetus at term (≥37 weeks) between January 2020 and August 2021. The outcomes will be mode of delivery, maternal and neonatal morbidity, discomfort/pain assessments during cervical ripening, women’s experience and satisfaction, and the impact of cervical ripening on the health-related quality of life at 3 months. If it reports a significant efficacy/safety/perinatal morbidity/women’s satisfaction/quality of life at 3 months post-delivery associated with a method of cervical ripening in a specific situation (gestational and/or fetal disease) using a multivariate analysis, its use should be reconsidered in clinical practice. Discussion This study will reveal that some cervical ripening methods will be more effectiveness, safe, with good women’s experiences and QOL at 3 months compared to others regarding maternal and obstetric characteristics. Trial registration This study is being performed at La Roche sur Yon Hospital following registration as GNEDS on January 8, 2020.

Prospective assessment of vacuum deliveries from midpelvic station in a tertiary care university hospital: Frequency, failure rates, labor characteristics and maternal and neonatal complications. PLoS One 2021; 16:e0259926. [PMID: 34784382 PMCID: PMC8594828 DOI: 10.1371/journal.pone.0259926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 11/02/2021] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Midpelvic vacuum extractions are controversial due to reports of increased risk of maternal and perinatal morbidity and high failure rates. Prospective studies of attempted midpelvic vacuum outcomes are scarce. Our main aims were to assess frequency, failure rates, labor characteristics, maternal and neonatal complications of attempted midpelvic vacuum deliveries, and to compare labor characteristics and complications between successful and failed midpelvic vacuum deliveries. STUDY DESIGN Clinical data were obtained prospectively from all attempted vacuum deliveries (n = 891) over a one-year period with a total of 6903 births (overall cesarean section rate 18.2% (n = 1258). Student's t-test, Mann-Whitney U-test or Chi-square test for group differences were used as appropriate. Odds ratios and 95% confidence intervals are given as indicated. The uni- and multivariable analysis were conducted both as a complete case analysis and with a multiple imputation approach. A p-value of <0.05 was considered statistically significant. RESULTS Attempted vacuum extractions from midpelvic station constituted 36.7% (n = 319) of all attempted vacuum extractions (12.9% (n = 891) of all births). Of these 319 midpelvic vacuum extractions, 11.3% (n = 36) failed and final delivery mode was cesarean section in 86.1% (n = 31) and forceps in the remaining 13.9% (n = 5). Successful completion of midpelvic vacuum by 3 pulls or fewer was achieved in 67.1%. There were 3.9% third-degree and no fourth-degree perineal tears. Cup detachments were associated with a significantly increased failure rate (adjusted OR 6.13, 95% CI 2.41-15.56, p< 0.001). CONCLUSION In our study, attempted midpelvic vacuum deliveries had relatively low failure rate, the majority was successfully completed within three pulls and they proved safe to perform as reflected by a low rate of third-degree perineal tears. We provide data for nuanced counseling of women on vacuum extraction as a second stage delivery option in comparable obstetric management settings with relatively high vacuum delivery rates and low cesarean section rates.

Severe maternal and neonatal morbidity after attempted operative vaginal delivery. Am J Obstet Gynecol MFM 2021; 3:100339. [PMID: 33631384 DOI: 10.1016/j.ajogmf.2021.100339] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 02/16/2021] [Accepted: 02/18/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Operative vaginal delivery is a critical tool in reducing primary cesarean delivery, but declining operative vaginal delivery rates and concerns about provider skill necessitate a clear understanding of risks. These risks are ambiguous because most studies compare outcomes of operative vaginal delivery with that of spontaneous vaginal delivery rather than outcomes of cesarean delivery in the second stage of labor, which is usually the realistic alternative. OBJECTIVE This study aimed to compare severe maternal and neonatal morbidity by mode of delivery of patients with a prolonged second stage of labor who had a successful operative vaginal delivery, a cesarean delivery after failed operative vaginal delivery, or a cesarean delivery without an operative vaginal delivery attempt. STUDY DESIGN We used a population-based database to evaluate nulliparous, term, singleton, vertex live births in California between 2007 and 2012 of patients with prolonged second stage of labor. Birth certificates and the International Classification of Diseases, Ninth Revision, Clinical Modification coded diagnoses and procedures were used for ascertainment of exposure, outcome, and demographics. Exposure was mode of delivery of patients who had any operative vaginal delivery attempt vs cesarean delivery without operative vaginal delivery attempt. The outcomes were severe maternal morbidity and severe unexpected newborn morbidity, defined using established indices. Anticipating that the code for prolonged second stage of labor would represent only a fraction of true operative vaginal delivery candidates, a secondary analysis was conducted removing this restriction to explore granular outcomes in a larger cohort with unsuccessful labor. Multivariable logistic regression was used to compare outcomes by mode of delivery adjusted for measured confounders. Sensitivity analyses were done excluding patients with combined vacuum-forceps-assisted delivery and birthweight of >4000 g. RESULTS A total of 9239 births after prolonged second stage of labor were included, where 6851 (74.1%) were successful operative vaginal deliveries, 301 (3.3%) were failed operative vaginal deliveries, and 2087 (22.6%) were cesarean deliveries without operative vaginal delivery attempts. Of successful operative vaginal deliveries, 6195 (90.4%) were vacuum assisted and 656 (10.6%) were forceps-assisted. Of failed operative vaginal deliveries where operative vaginal delivery type was specified, 83 (47.4%) were vacuum assisted, 38 (21.7%) were forceps-assisted, and 54 (30.9%) were combined vacuum-forceps-assisted. Of note, all 54 combined vacuum-forceps-assisted operative vaginal delivery attempts that we identified failed. The outcomes of patients with failed operative vaginal delivery differed from those with successful operative vaginal delivery, such as higher rates of comorbidities, use of combined operative vaginal delivery, and birthweight of >4000 g. Successful operative vaginal delivery was associated with reduced severe maternal morbidity (adjusted odds ratio, 0.55; 95% confidence interval, 0.39-0.78) without a difference in severe unexpected neonatal morbidity (adjusted odds ratio, 0.99; 95% confidence interval, 0.78-1.26). In contrast, failed operative vaginal delivery was associated with increased severe maternal morbidity (adjusted odds ratio, 2.14; 95% confidence interval, 1.20-3.82) and severe unexpected neonatal morbidity (adjusted odds ratio, 1.78; 95% confidence interval, 1.09-2.86). In addition, findings were similar in the secondary analysis of 260,585 patients with unsuccessful labor. CONCLUSION In this large cohort of nulliparous, term, singleton, vertex births, successful operative vaginal delivery was associated with a 45% reduction in severe maternal morbidity without differences in severe unexpected neonatal morbidity compared with cesarean delivery after prolonged second stage of labor. Operative vaginal delivery infrequently failed and was associated with a 214% increase in severe maternal morbidity and a 78% increase in severe unexpected neonatal morbidity; furthermore, combined operative vaginal deliveries were major contributors to this, as all combined operative vaginal deliveries failed. Optimization of operative vaginal delivery success rates through means such as improved patient selection, enhanced provider skill, and discussions against combined operative vaginal delivery could reduce maternal and neonatal complications.

Abstract
BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a common disease during controlled ovarian hyperstimulation treatment. However, the obstetric and neonatal outcomes of this group of patients are unknown. The aim of this study was to explore the effects of late moderate-to-critical OHSS on obstetric and neonatal outcomes. METHODS This prospective observational study included 17,537 patients who underwent IVF/ICSI-fresh embryo transfer (ET) between June 2012 and July 2016 and met the inclusion criteria, including 7,064 eligible patients diagnosed with clinical pregnancy. Ultimately, 6,356 patients were allocated to the control group, and 385 patients who were hospitalized and treated at the center for late moderate-to-critical OHSS were allocated to the OHSS group. Then, propensity score matching analysis was performed, matching nine maternal baseline covariates and the number of multiple gestations; 385 patients with late moderate-to-critical OHSS were compared with a matched control group of 1,540 patients. The primary outcomes were the live birth rate, preterm delivery rate, miscarriage rate, gestational age at birth (weeks), obstetric complications and neonatal complications. RESULTS The duration of gestation in the matched control group was significantly higher than that in the OHSS group. The live birth delivery rate did not significantly differ between the OHSS and matched control groups. The incidence rates of the obstetric complications venous thrombosis (VT) and gestational diabetes mellitus (GDM), neonatal complications and the number of neonates admitted to the NICU were significantly higher in the OHSS group than in the matched control group. CONCLUSIONS Pregnant women undergoing IVF with fresh ET whose course is complicated by late moderate-to-critical OHSS appear to experience shortened gestation and increased obstetrical and neonatal complications compared with matched controls whose course is not complicated by OHSS. However, the live birth rate, average neonatal weight, and incidence rates of premature delivery, miscarriage, early abortion, hypertensive disorder of pregnancy (HDP), placenta previa (PP), intrahepatic cholestasis of pregnancy (ICP), and low neonatal birth weight (LBW) did not differ significantly between the two groups.

Abstract
Background Postpartum maternal infection is still a common problem worldwide, mainly due to obstetric risk factors. The use of prophylactic antibiotic at operative vaginal delivery (OVD), taking it as a standalone risk factor, has been controversial. The purpose of this review was to rigorously evaluate the association of OVD with postpartum infection and shed light on such highly controversial issue. Methods A computer-based literature search was done mainly in the databases of PUBMED, HINARI health research, and the Cochrane library. Systematic review and meta-analysis were done by including 14 articles published between 1990 and August 2019. Results The average absolute risk of postpartum infection at OVD from seven large cohort studies was 1%. Few studies showed a weak association of OVD with postpartum infection without being adjusted to perineal wound, but the pooled meta-analysis showed statistically significant association with non-OVD. In the included randomized trial, 97% of the study participants had perineal wound for whom repairs were performed; the risks of maternal infection and perineal wound breakdown were comparable, and maternal infections other than perineal wound infection did not show significant difference between prophylactic antibiotic and placebo groups. The majority of included studies demonstrated a strong association of postpartum infection and perineal wound dehiscence with episiotomy and perineal tear. Conclusion Both the relative and absolute risks of postpartum infection at OVD are extremely low unless accompanied by episiotomy and 3rd/4tht degree perineal tear. From previous studies, there is no substantial evidence to use prophylactic antibiotic at OVD, but episiotomy and perineal tear.

Abstract
Objective: To evaluate associations between operative vaginal delivery complications and provider experience (operative vaginal delivery volume and time since residency).Methods: We included all operative vaginal deliveries between 2008 and 2014 at a tertiary care teaching hospital, stratified into forceps-assisted and vacuum-assisted deliveries. Complications included severe perineal lacerations (3rd and 4th degree) and neonatal injuries (subgaleal/subdural/cerebral hemorrhage, facial nerve injury, and scalp injury), which were identified by International Classification Diagnosis-9 codes. Providers were categorized by operative vaginal delivery volume (mean annual forceps- or vacuum-assisted deliveries over the study interval) and time since residency. Regression analyses were used to compare complication rates by provider volume and time since residency, adjusting for potential confounders, using 0-1 deliveries per year and <5 years since residency as reference groups.Results: Nine hundred and thirty-four forceps and 1074 vacuums occurred. For forceps-assisted deliveries, severe perineal injury was decreased among providers with >10 forceps per year (aOR 0.50 [95%CI 0.30-0.81]) and at 15-19 years (aOR 0.45 [95% CI 0.22-0.94], and ≥25 years (aOR 0.45 [0.27-0.73]) since residency. There were no associations with neonatal injuries. Among vacuum-assisted deliveries, severe perineal injury decreased at ≥25 years since residency (aOR 0.35 [95%CI 0.17-0.74], with no association with provider volume. Neonatal injury decreased at 5-9 years (aOR 0.53 [95%CI 0.30-0.93]), and 15-19 years since residency (aOR 0.53 [95%CI 0.29-0.97]), due to differences in scalp injuries. Neonatal injuries other than scalp injury were rare.Conclusion: Severe perineal lacerations decreased with increasing operative vaginal delivery experience, primarily among forceps-assisted vaginal delivery. Providers >5 years since residency may have lower scalp injury with vacuums, but this cohort was largely underpowered for neonatal injury.

Abstract
BACKGROUND To assess both severe maternal and neonatal mortality and morbidity after attempted operative vaginal deliveries by residents under supervision and by attending obstetricians. STUDY DESIGN Secondary analysis of a 5-year prospective study with cross-sectional analysis including 2192 women with live singleton term fetuses in vertex presentation who underwent an attempted operative vaginal delivery in a tertiary care university hospital. Obstetricians who attempted or performed an operative vaginal delivery were classified into 2 groups according to their level of experience: attending obstetricians (who had 5 years or more of experience) and obstetric residents (who had less than 5 years of experience) under the supervision of an attending obstetrician. We used multivariate logistic regression and propensity score methods to compare outcomes associated with attending obstetricians and obstetric residents. Severe maternal morbidity was defined as third- or fourth-degree perineal laceration, perineal hematoma, cervical laceration, extended uterine incision for cesareans, postpartum hemorrhage >1500 mL, surgical hemostatic procedures, uterine artery embolization, blood transfusion, infection, thromboembolic events, admission to the intensive care unit, or maternal death; severe neonatal morbidity was defined as a 5-minute Apgar score <7, umbilical artery pH <7.00, need for resuscitation or intubation, neonatal trauma, intraventricular hemorrhage greater than grade 2, neonatal intensive care unit admission for more than 24 hours, convulsions, sepsis, or neonatal death. RESULTS High prepregnancy body mass index, high dose of oxytocin, manual rotation, persistent occiput posterior or transverse positions, operating room delivery, midpelvic delivery, forceps, and spatulas were significantly more frequent in deliveries managed by attending obstetricians than residents whereas a second-stage pushing phase longer than 30 minutes was significantly more frequent in deliveries managed by residents. The rate of severe maternal morbidity was 7.8% (115/1475) for residents vs 9.9% (48/484) for attending obstetricians; for severe neonatal morbidity, the rates were 8.3% (123/1475) vs 15.1% (73/484), respectively. In the univariate, multivariable, and sensitivity analyses, attempted operative vaginal delivery managed by a resident was significantly and inversely associated with severe neonatal but not maternal morbidity. After propensity score matching, delivery managed by a resident was not significantly associated with severe maternal morbidity (adjusted odds ratio, 0.74; 95% confidence interval, 0.39-1.38) and was no longer associated with neonatal morbidity (adjusted odds ratio, 0.51; 95% confidence interval, 0.25-1.04). CONCLUSION Management of attempted operative vaginal deliveries by residents under the supervision of attending obstetricians, compared with by the attending obstetricians themselves, does not appear to be associated with either maternal or neonatal morbidity. These reassuring results support the continued use of residency programs for training in operative vaginal deliveries under the supervision of attending obstetricians.

Abstract
BACKGROUND Intrapartum ultrasound scanning has been proposed as an ancillary tool in the decision-making process of instrumental vaginal delivery. OBJECTIVE The purpose of this study was to evaluate the correlation between the sonographic visualization with a transperineal scan of the fetal occiput or forehead distal to the pubic symphysis with anterior or posterior presentation, respectively (fetal occiput or forehead sign), and the outcome of a vacuum delivery. STUDY DESIGN We conducted a retrospective cohort study of patients who underwent a vacuum application in our hospital from 2011-2017, excluding outlet applications. In each case, a preliminary transperineal scan was performed to confirm fetal presentation and position and to demonstrate the presence or absence of the fetal occiput or forehead sign. The head direction, angle of progression, and the head perineum distance were also noted. The primary outcome measure was the success of the vacuum. The secondary outcome measures included fetal complications and perineal lacerations. RESULTS A total of 196 consecutive patients were enrolled in the study. The occiput or forehead sign was present in 150 and was associated with a successful vaginal extraction in all cases. Of the 46 cases without the sign, 5 babies (10.8%) were delivered by cesarean section after a failed vacuum (P=.0006). The occiput or forehead sign was also associated with fewer grade 3-4 perineal lacerations (10.7% vs 35.7%; P=.0005) and cephalohematomas, although the difference was not statistically significant (1.4% vs 4.3%). There was a good correlation between the occiput or forehead sign and the other sonographic methods that previously had been proposed to predict a successful vacuum extraction, such as head direction, angle of progression, and head perineum distance. CONCLUSION In our hands, the fetal occiput or forehead sign was associated strongly with successful vacuum application and with a very low rate of maternal and fetal complications.

Morbidity and Mortality Associated With Forceps and Vacuum Delivery at Outlet, Low, and Midpelvic Station. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2018; 41:327-337. [PMID: 30366887 DOI: 10.1016/j.jogc.2018.06.018] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 06/11/2018] [Indexed: 01/18/2023]
Abstract
OBJECTIVE This study sought to quantify perinatal and maternal morbidity and mortality associated with forceps and vacuum delivery compared with Caesarean delivery in the second stage of labour and to estimate whether these associations differed by pelvic station. METHODS The investigators conducted a population-based, retrospective cohort study of term singleton deliveries by operative delivery with prolonged second stage of labour in Canada (2003-2013) using national hospitalization data. The primary study outcomes were severe perinatal morbidity and mortality (i.e., seizures, assisted ventilation, severe birth trauma, and perinatal death) and severe maternal morbidity and mortality (i.e., severe postpartum hemorrhage, cardiac complication, and maternal death). Logistic regression was used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) after stratifying by indication (dystocia or fetal distress). The Breslow-Day chi-square test for heterogeneity in ORs was used to test effect modification by pelvic station (outlet, low, or midpelvic). RESULTS There were 61 106 deliveries included in the study. Among women with dystocia, forceps and vacuum deliveries were associated with higher rates of perinatal morbidity and mortality compared with Caesarean delivery (forceps: aOR 1.56; 95% CI 1.13-2.17; vacuum: aOR 1.44; 95% CI 1.06-1.97). Vacuum delivery was associated with lower rates of maternal morbidity and mortality compared with Caesarean delivery (dystocia: aOR 0.64; 95% CI 0.51-0.81; fetal distress: aOR 0.43; 95% CI 0.32-0.57). Pelvic station did not significantly modify the associations between forceps or vacuum and perinatal or maternal morbidity and mortality. CONCLUSION Forceps and vacuum delivery is associated with increased rates of severe perinatal morbidity and mortality compared with Caesarean delivery among women with dystocia, whereas vacuum delivery is associated with decreased rates of severe maternal morbidity and mortality.

Abstract
During the past decade, there has been an increase in the awareness of infections associated with pregnancy and delivery. The most significant cause of post-partum infection is caesarean section; 20-25% of operations are followed by wound infections, endometritis or urinary tract infections. Approximately 13% of women in the UK undergo operative vaginal delivery (OVD) with forceps or vacuum, which is also associated with an increased risk of infection, estimated at 0.7%-16% of these deliveries. Despite this, previous reviews have identified only one small trial of antibiotic prophylaxis in 393 women and concluded that there was insufficient evidence to support the routine use of prophylactic antibiotics after OVD. The ANODE trial, a multicentre, blinded, placebo-controlled trial from the UK, is due to report findings from more than 3400 women in 2019 and will be the largest study to date of antibiotic prophylaxis following OVD.

Abstract
OBJECTIVE Instrumental vaginal delivery is associated with birth trauma to infant and obstetric trauma to mother. As caesarean delivery rates increased during the past decades, the rate of instrumental vaginal delivery declined. We examined concomitant temporal changes in the rates of severe birth trauma and maternal obstetric trauma. DESIGN A retrospective observational study. SETTINGS AND PARTICIPANTS All hospital singleton live births in Washington State, USA, 2004-2013, excluding breech delivery. Severe birth trauma (brain, nerve injury, fractures and other severe birth trauma) and obstetric trauma (third/fourth degree perineal lacerations, cervical/high vaginal lacerations) were identified from hospitalisation data. Pregnancy and delivery characteristics were obtained from birth certificates. Temporal trends were assessed by the Cochran-Armitage test. Logistic regression was used to obtain adjusted ORs (AORs) and 95% CI. RESULTS Overall, 732 818 live births were included. The rate of severe birth trauma declined from 5.3 in 2004 to 4.5 per 1000 live births in 2013 (P<0.001). The decline was observed only in spontaneous vaginal delivery, the rates of fractures and other severe birth trauma declined by 5% and 4% per year, respectively (AOR: 0.95, 95% CI 0.94 to 0.97 and AOR: 0.96, 95% CI 0.93 to 0.99; respectively). The rate of third/fourth degree lacerations declined in spontaneous vaginal delivery from 3.5% to 2.3% (AOR: 0.95; 95% CI 0.94 to 0.95) and in vacuum delivery from 17.3% to 14.5% (AOR: 0.97, 95% CI 0.96 to 0.98). Among women with forceps delivery, these rates declined from 29.8% to 23.4% (AOR: 0.98, 95% CI 0.96 to 1.00). CONCLUSION While the rates of fractures and other birth trauma declined among infants delivered by spontaneous vaginal delivery, the rate of birth trauma remained unchanged in instrumental vaginal delivery and caesarean delivery. Among mothers, the rates of severe perineal lacerations declined, except for women with forceps delivery.

Abstract
BACKGROUND Increased use of operative vaginal delivery (i.e., forceps or vacuum application), of which 20% occurs at midpelvic station, has been advocated to reduce the rate of cesarean delivery. We aimed to quantify severe perinatal and maternal morbidity and mortality associated with attempted midpelvic operative vaginal delivery. METHODS We studied all term singleton deliveries in Canada between 2003 and 2013, by attempted midpelvic operative vaginal or cesarean delivery with labour (with and without prolonged second stage). The primary outcomes were composite severe perinatal morbidity and mortality (e.g., convulsions, assisted ventilation, severe birth trauma and perinatal death), and composite severe maternal morbidity and mortality (e.g., severe postpartum hemorrhage, shock, sepsis, cardiac complications, acute renal failure and death). RESULTS The study population included 187 234 deliveries. Among women with dystocia and prolonged second stage of labour, midpelvic operative vaginal delivery was associated with higher rates of severe perinatal morbidity and mortality compared with cesarean delivery (forceps, adjusted odds ratio [AOR] 1.81, 95% confidence interval [CI] 1.24 to 2.64; vacuum, AOR 1.81, 95% CI 1.17 to 2.80; sequential instruments, AOR 3.19, 95% CI 1.73 to 5.88), especially with higher rates of severe birth trauma. Rates of severe maternal morbidity and mortality were not significantly different after operative vaginal delivery, although rates of obstetric trauma were higher (forceps, AOR 4.51, 95% CI 4.04 to 5.02; vacuum, AOR 2.70, 95% CI 2.35 to 3.09; sequential instruments, AOR 4.24, 95% CI 3.46 to 5.19). Among women with fetal distress, similar associations were seen for severe birth trauma and obstetric trauma, although vacuum was associated with lower rates of severe maternal morbidity and mortality (AOR 0.52, 95% CI 0.33 to 0.80). Associations tended to be stronger among women without a prolonged second stage. INTERPRETATION Midpelvic operative vaginal delivery is associated with higher rates of severe birth trauma and obstetric trauma, whereas overall rates of severe perinatal and maternal morbidity and mortality vary by indication and operative instrument.

Abstract
Objective To evaluate the effect of the fetal head station at attempted operative vaginal delivery (aOVD), and specifically midpelvic or low aOVD, on female and male sexual function and symptoms of postpartum depression (PPD) at 6 months. Design Prospective population-based cohort study. Setting 1,941 women with singleton term fetuses in vertex presentation with midpelvic or low aOVD between 2008 and 2013 in a tertiary care university hospital. Methods Symptoms of female sexual dysfunction using the Pelvic Organ Prolapse/Urinary Incontinence/Sexual Function Short Form Questionnaire (PISQ-12), symptoms of PPD using the Edinburgh Postnatal Depression Scale (EPDS) score, symptoms of male sexual dysfunction using the International Index of Erectile Function (IIEF-15) and perineal pain were assessed 6 months after aOVD. We measured the association between midpelvic or low aOVD and symptoms of female and male sexual function and symptoms of PPD at 6 months using multiple regression and adjusting for demographics, and risk factors of sexual dysfunction, symptoms of PPD and perineal pain with adjusted odds ratios (aORs) and 95% confidence intervals (95% CI). Results The study included 907 women (46.7%) who responded to the questionnaire; 18.4% (167/907) had midpelvic aOVD, and 81.6% (740/907) low. Most women (873/907 [96.3%]) of those with partners reported sexual activity at 6 months. No significant difference was observed for PISQ-12, EPDS, IIEF-15 scores and perineal pain between mid and low pelvic groups. Compared with low pelvic aOVD, midpelvic aOVD was not significantly associated with either female or male sexual dysfunction (p = 0.89 and p = 0.76, respectively), or maternal symptoms of PPD (p = 0.83). Perineal pain significantly increased the risk of male and female sexual dysfunction and maternal symptoms of PPD at 6 months (p = 0.02, p = 0.006, and p = 0.02, respectively). Conclusion Midpelvic compared with low pelvic aOVD was not associated with an increase in sexual dysfunction, nor with symptoms of PPD at 6 months.

Abstract
BACKGROUND Vaginal delivery, especially operative assisted vaginal delivery, seems to be a major stressor for the neonate. The objective of this study was to evaluate the stress response after metal cup versus Kiwi Omnicup® ventouse delivery. METHODS The study was a secondary observational analysis of data from a former prospective randomised placebo controlled multicentre study on the analgesic effect of acetaminophen in neonates after operative vaginal delivery and took place at three Swiss tertiary hospitals. Healthy pregnant women ≥35 weeks of gestation with an estimated fetal birth weight above 2000 g were recruited after admission to the labour ward. Pain reaction was analysed by pain expression score EDIN scale (Échelle Douleur Inconfort Nouveau-Né, neonatal pain and discomfort scale) directly after delivery. For measurement of the biochemical stress response, salivary cortisol as well as the Bernese Pain Scale of Newborns (BPSN) were evaluated before and after an acute pain stimulus (the standard heel prick for metabolic testing (Guthrie test)) at 48-72 h. RESULTS Infants born by vaginal operative delivery displayed a lower pain response after plastic cup than metal cup ventouse delivery (p < 0.001), but the pain response was generally lower than expected and they recovered fully within 72 h. CONCLUSIONS Neonatal pain response is slightly reduced after use of Kiwi OmniCup® versus metal cup ventouse. TRIAL REGISTRATION Trial was registered under under NCT00488540 on 19th June 2007.

Abstract
Objective To evaluate the effect of the fetal head station at attempted operative vaginal delivery (aOVD), and specifically midpelvic or low aOVD, on urinary incontinence (UI), anal incontinence (AI), and perineal pain at 6 months. Design Prospective cohort study. Setting 1941 women with singleton term fetuses in vertex presentation with midpelvic or low aOVD between 2008 and 2013 in a tertiary care university hospital. Methods Symptoms of urinary incontinence (UI) using the Bristol Female Lower Urinary Tract Symptoms questionnaire, and symptoms of anal incontinence (AI) severity using Fecal Incontinence Severity Index (FISI) were assessed 6 months after aOVD. We measured the association between midpelvic or low aOVD and symptoms of UI, AI, and perineal pain at 6 months using multiple regression and adjusting for demographics, and risk factors of UI and AI, with adjusted odds ratios (aORs) and 95% confidence intervals (95% CI). Results The study included 907 women (46.7%) who responded to the questionnaire; 18.4% (167/907) had midpelvic aOVD, and 81.6% (740/907) low; and none of women with symptoms of UI (26.6%, and 22.4%, respectively; p = 0.31), AI (15.9%, and 21.8%; p = 0.09), the FISI score, and perineal pain (17.2%, and 12.7%; p = 0.14) differed significantly between groups. The same was true for stress, urge, and mixed-type UI, severe UI and difficulty voiding. Compared with low pelvic aOVD, the aORs for symptoms of UI in midpelvic aOVD were 0.70 (0.46–1.05) and AI 1.42 (0.85–2.39). Third- and fourth-degree tears were a major risk factor of symptoms of UI (aOR 3.08, 95% CI 1.35–7.00) and AI (aOR 3.47, 95% CI 1.43–8.39). Conclusion Neither symptoms of urinary nor anal incontinence differed at 6 months among women who had midpelvic and low pelvic aOVD. These findings are reassuring and need further studies at long-term to confirm these short-term data.
