Abstract
INTRODUCTION The "en caul" technique, i.e. delivery with intact membranes, may reduce the risk of obstetric trauma in vaginal breech delivery of extreme preterm infants. We aimed at comparing perinatal mortality and morbidity among extremely preterm breech vaginal deliveries between infants delivered "en caul" and those with "ruptured membranes". MATERIAL AND METHODS We performed a fourteen-year retrospective study in a tertiary university center. All vaginal deliveries of singleton breech live infants with an antenatal decision of active resuscitation between 24 weeks and 27+6 weeks were included. Perinatal outcomes were compared between the "en caul" group, with intact membranes at the onset of pushing efforts and the "ruptured membranes" group, with ruptured membranes at the onset of pushing efforts. The primary outcome was perinatal mortality defined by intrapartum or neonatal death. The secondary outcomes were fetal extraction difficulties, arterial pH and 5 min Apgar score. RESULTS We included 52 infants in the "en caul" group and 71 in the "ruptured membranes" group. The perinatal mortality rate did not differ between the two groups (19.2% in the "en caul" group versus 28.2% in the "ruptured membranes" group, p = 0.25). The mean arterial pH at birth was higher in the « en caul » group (7.32 ± 0.1 vs 7.24 ± 0.1, p = 0.001). There were no differences between the groups for fetal extraction difficulties, especially fetal head entrapment (9.6% versus 9.9%). CONCLUSION Even though the "en caul" technique does not seem to decrease the perinatal mortality rate, it remains a simple technique, which could improve neonatal morbidity.

Abstract
OBJECTIVES To compare mortality, morbidity and neurodevelopment by mode of delivery (MOD) for very preterm births with low prelabour risk of caesarean section (CS). METHODS The study was a population-based prospective cohort study in 19 regions in 11 European countries. Multivariable mixed effects models and weighted propensity score models were used to estimate adjusted odds ratios (aOR) by observed MOD and the unit's policy regarding MOD. Population: Singleton vertex-presenting live births at 24 + 0 to 31 + 6 weeks of gestation without serious congenital anomalies, preeclampsia, HELLP or eclampsia, antenatal detection of growth restriction and prelabour CS for fetal or maternal indications. RESULTS Main outcome measures: A composite of in-hospital mortality and intraventricular haemorrhage (grade III/IV) or periventricular leukomalacia. Secondary outcomes were components of the primary outcome, 5 min Apgar score <7 and moderate to severe neurodevelopmental impairment at two years of corrected age. The rate of CS was 29.6% but varied greatly between countries (8.0-52.6%). MOD was not associated with the primary outcome (aOR for CS 0.99; 95% confidence interval [CI] 0.65-1.50) when comparing units with a systematic policy of CS or no policy of MOD to units with a policy of vaginal delivery (aOR 0.88; 95% CI 0.59-1.32). No association was observed for two-year neurodevelopment impairment for CS (aOR 1.15; 95% CI 0.66-2.01) or unit policies (aOR 1.04; 95% CI 0.63-1.70). CONCLUSIONS Among singleton vertex-presenting live births without medical complications requiring a CS at 24 + 0 to 31 + 6 weeks of gestation, CS was not associated with improved neonatal or long-term outcomes.

[PMID: 33932682 DOI: 10.1016/j.ejogrb.2021.04.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 03/13/2021] [Accepted: 04/19/2021] [Indexed: 12/26/2022]
Abstract
OBJECTIVE More than half of extremely preterm infants are delivered by cesarean section. Few data are available about severe maternal morbidity (SMM) of these extremely preterm cesarean. The objective was to determine whether gestational age under 26 weeks of gestation (weeks) was associated with an increased risk of SMM compared with gestational age between 26 and 34 weeks in women having a cesarean delivery. MATERIAL AND METHODS We searched MEDLINE, ISI Web of Science, the Cochrane Database, PROSPERO, and ClinicalTrials.gov on January 31, 2020. The search strategy clustered terms describing SMM and preterm cesarean delivery. No restrictions on language, publication status, and study design were applied. Abstracts were included if there was sufficient information to assess study quality. The authors of all identified studies were contacted to request for aggregated data. Relative risks (RR) were calculated using the inverse variance method. The primary outcome was SMM as defined in each study. We analyzed data on preterm cesarean deliveries between 22 and 34 weeks. The protocol was registered in PROSPERO (registration: CRD42019128644). RESULTS Six studies involving 45,572 women (3,440 delivering < 26 weeks; 42,132 delivering between 26 and 34 weeks) were included. SMM occurred in 607 women (17.6 %) < 26 weeks and 4,483 women (10.6 %) between 26 and 34 weeks. Gestational age < 26 weeks was associated with an increased risk of SMM (RR, 1.65; 95 % CI [Confidence Interval], 1.52-1.78; I2 = 40 %). Gestational age < 26 weeks remained associated with SMM in the subgroup analyses depending on the type of the study (prospective or retrospective), country of the study (European or non-European), and high quality of the study. A sensitivity analysis showed that gestational age < 25 weeks was also associated with SMM in preterm cesarean delivery (RR, 1.66; 95 % CI, 1.50-1.83; I2 = 3%). CONCLUSIONS Gestational age < 26 weeks was associated with an increased risk of SMM in women having a preterm cesarean delivery. Obstetricians and neonatologists should be aware of the increased risk of SMM in cesarean.

Abstract
AIM To quantify the impact of the number of prior cesarean deliveries (CD) on operative complications and preterm birth. Then to investigate the presence of a threshold, beyond which complications tend to be disproportionately dangerous. METHODS This was a retrospective cohort observational study, where data corresponding to all CD done at our service, during an 8-year period, were collected and analyzed. In total, 1840 CD were performed. Patients were divided into five categories that corresponded to the number of CD. Primary outcome was the composite adverse maternal outcome, while preterm birth and individual complications were secondary outcomes. RESULTS The composite adverse maternal outcome, preterm birth, as well as all individual complications related to CD, except for placental abruption, showed a significant rise in frequency that paralleled the increase in the number of CD. Furthermore, this increase tended to be continuous as the number of CD increased, with an evident surge after the fourth. CONCLUSION In our population, increasing number of prior CD was a risk factor for a parallel increase in the rate of composite adverse maternal outcome, preterm birth and almost all intraoperative complications attributable to CD. Decreasing exposure to such surgeries by limiting family size to four offspring should be considered seriously in patient counseling.

Abstract
OBJECTIVE To evaluate the benefit/risk balance of way of birth according to fetal presentation, to assess monitoring during preterm labor, to discuss method of delivery and practice of delayed cord clamping in case of spontaneous preterm birth. METHODS Bibliographic research from the Pubmed database and recommendations issued by the main scientific societies, and assignment of a level of evidence and a recommendation grade. RESULTS In case of vertex presentation, no studies suggest that cesarean section improve neonatal outcome during spontaneous preterm birth (LE4). Nevertheless, cesarean is associated with higher maternal morbidity than vaginal delivery. Thus, routine cesarean is not recommended simply because of a spontaneous preterm labor (professional consensus). The available data do not allow specific recommendations about the choice of mode of delivery for preterm breech presentation in view of the low levels of proof (Professional consensus). Fetal rate monitoring is necessary during preterm labor (Professional consensus). Current data about second lines method for fetal surveillance (fetal scalp blood for pH or lactates) are insufficient to recommend their use before 34 WG (Professional consensus). Systematic assisted vaginal delivery is not recommended during preterm birth (Professional consensus). Use of vacuum is possible after 34 WG when cranial vertex ossification is considered satisfactory (Professional consensus). Systematic use of episiotomy in case of preterm birth is not recommended (Professional consensus). A delayed cord clamping is possible if the neonatal or maternal state so permits (Professional consensus). The available data are insufficient to recommend a systematic use of this procedure (LE3). CONCLUSION In case of preterm delivery, the available data do not allow specific recommendations about the choice of mode of delivery regardless of fetal presentation.

Abstract
OBJECTIVE To investigate the risk of uterine rupture in women with prior periviable cesarean delivery and prior term cesarean delivery independent of initial incision type. METHODS We conducted a retrospective longitudinal cohort study using Washington state birth certificate data and hospital discharge records, identifying primary cesarean deliveries performed at 20-26 weeks and 37-41 weeks of gestation with subsequent delivery between 1989 and 2008. We compared subsequent uterine rupture risk in the two groups considering both primary incision type and subsequent labor induction and augmentation. RESULTS We identified 456 women with index periviable cesarean delivery and 10,505 women with index term cesarean delivery. Women with index periviable cesarean delivery were younger, more frequently of nonwhite race, more likely to smoke, and more likely to have hypertension. Women in the periviable group had more index classical incisions (42% compared with 1%, P<.001) and fewer subsequent inductions and augmentations (8% compared with 16%, P<.001). Uterine rupture in the subsequent pregnancy occurred more frequently among women in the index periviable group than those in the index term group (8/456 [1.8%] compared with 38/10,505 [0.4%], odds ratio [OR] 4.9, 95% confidence interval [CI] 2.3-10.6). This relationship persisted among women with a low transverse incision (4/228 [1.8%] compared with 36/9,558 [0.4%], OR 4.7, 95% CI 1.7-13.4). CONCLUSION Cesarean delivery at periviability compared with term is associated with an increased risk for uterine rupture in a subsequent pregnancy, even after low transverse incision. These data support judicious use of cesarean delivery at periviable gestational ages and inform subsequent counseling. LEVEL OF EVIDENCE II.

Abstract
Caesarean delivery is frequently complicated by surgical site infections, endometritis and urinary tract infection. Most surgical site infections occur after discharge from the hospital, and are increasingly being used as performance indicators. Worldwide, the rate of caesarean delivery is increasing. Evidence-based guidelines recommended the use of prophylactic antibiotics before surgical incision. An exception is made for caesarean delivery, where narrow-range antibiotics are administered after umbilical cord clamping because of putative neonatal benefit. However, recent evidence supports the use of pre-incision, broad-spectrum antibiotics, which result in a lower rate of maternal morbidity with no disadvantage to the neonate.

Abstract
OBJECTIVE The purpose of this study was to determine complication rates after cesarean delivery and to identify independent risk factors for complications. STUDY DESIGN In a prospective population-based cohort study in Norway, rates of predefined types of complications from 2751 cesarean deliveries were determined. The complications that were studied were intraoperative complications, blood loss, wound infection, cystitis, endometritis, hematoma, and reoperation. Independent risk factors were identified by stratification and multiple logistic regression analysis. RESULTS Altogether, 21.4% of the women had > or =1 complications. The degree of cervical dilation, general anesthesia, low gestational age, and fetal macrosomia were independent risk factors. For operations that were performed at 9 to 10 cm cervical dilation, the complication rate was 32.6% versus 16.8% at 0 cm (odds ratio, 2.39; 95% CI, 1.77-3.22; P<.001). CONCLUSION Cesarean delivery was associated with a high complication rate. Increasing cervical dilation and, in particular, cervical dilation of 9 or 10 cm at the time of operation, general anesthesia, low gestational age, and fetal macrosomia were identified as independent risk factors.

Abstract
In many countries caesarean section has become the mode of delivery in over a quarter of all births. Safety of the mother and cost are the two main areas of concern. Various studies on the techniques of performing a caesarean section have focused on reducing the operating time, blood loss, wound infection and cost. Given the fact that caesarean section is the most commonly performed operation in obstetrics, it is important that trainers and trainees are familiar with the basic surgical techniques and that best practice is followed. At the same time surgeons should take necessary precautions to reduce their risk of exposure to Hepatitis B and HIV. The skin incision and entry into abdominal cavity is best achieved by the modified Cohen's incision. The lower segment transverse uterine incision has stood the test of time over a period of 75 years and remains the best way to enter the uterus. Closure of the uterus in single layer appears to be acceptable, whenever technically possible. Placental delivery should be by controlled cord traction after spontaneous expulsion. Closure of the visceral and parietal layers of the peritoneum no longer seems to be necessary. Obliteration of space in the subcutaneous layer, either by suture or by suction, seems to reduce wound disruption. These issues are being considered in the CAESAR randomized controlled trial of surgical techniques currently underway in England.Prophylactic antibiotics are mandatory in preventing post-operative morbidity. Many of the above mentioned steps have been tested in randomized trials. Further studies are needed to examine a wide range of questions arising from this review, e.g. best position of the patient, the value of exteriorization of the uterus whilst repairing the uterus, and the use of agents to relax the uterus in difficult deliveries.

Abstract
OBJECTIVE We evaluated the safety of intraoperative autologous blood collection and autotransfusion during cesarean section. STUDY DESIGN A multicenter historical cohort study identified 139 patients in whom autologous blood collection autotransfusion during cesarean section was performed. We also identified 87 control patients who underwent similar surgical procedures at the same centers without autotransfusion. The outcome variables we compared were acute respiratory distress syndrome, amniotic fluid embolism, disseminated intravascular coagulation, need for ventilatory support, infectious morbidity, and the length of postpartum hospitalization. RESULTS Demographic and obstetric characteristics were similar in both groups. The ranges of autotransfused volumes were 200 to 11,250 mL at Yale, 225 to 1160 mL at Good Samaritan, and 125 to 4750 mL at Hinsdale. No statistically significant differences existed between the two groups in any of the outcome variables analyzed. No case of acute respiratory distress syndrome or amniotic fluid embolism was identified in either group. CONCLUSIONS Our multicenter experience reveals no demonstrably increased risk of complications in patients receiving autologous blood collection autotransfusion during cesarean section.
