Abstract Objective The appropriate delivery mode for twins is discussed controversially in the literature. The aim of this study was to investigate delivery modes and short-term neonatal outcomes of twin pregnancies delivered in University Hospital Leipzig. Material and Methods A total of 274 twin pregnancies (32.0 to 39.4 weeks of gestation) delivered between 2015 and 2017 were analyzed retrospectively with regard to the planned and final delivery mode as well as neonatal outcomes. The inclusion and exclusion criteria for vaginal delivery were comparable to those of the Twin Birth Study. Results The spontaneous birth rate for births planned as vaginal deliveries was 78.5%; the rate of secondary cesarean section was 19.4%. The final total cesarean rate was 58.8%, and the rate of vaginal deliveries was 41.2%. Vertex or non-vertex position of the second twin had no significant effect on neonatal outcome or mean delivery interval between the birth of the first and second twin. Chorionicity, neonatal weight and gender had no significant impact on delivery mode. However, successful vaginal delivery was associated with higher gestational age and both fetuses in vertex position. The combined neonatal outcome for both twins was significantly worse if they were delivered by cesarean section compared to spontaneous birth. In addition, the leading twin in monochorionic/diamniotic (MC/DA) pregnancies was intubated more frequently after cesarean delivery and had significantly lower Apgar scores. Conclusion Vaginal delivery in twin pregnancies is a practicable and safe option in specific defined conditions and when the appropriate infrastructure and clinical experience is available.

Abstract Purpose Numbers of planned cesarean deliveries are increasing in twin pregnancies, despite the lack of evidence for this approach, and the second twin is thought to be at risk for a poorer outcome. The aim of this study was to examine whether twins have a poorer outcome if an attempted vaginal delivery is changed to a cesarean section or combined delivery. Methods This retrospective data analysis included all women with dichorionic twin pregnancies attempting vaginal delivery over a 10-year period. Outcome parameters for the first and second twins relative to their mode of birth were compared. A correlation model between the interdelivery time interval and Apgar scores was calculated. Subgroup analyses assessing the birth mode of the first and second twins were conducted. Results A total of 248 women were enrolled in the study. The second twins had significantly lower values for outcome parameters, such as umbilical artery cord pH and Apgar scores in comparison with the first twins (P < 0.01). The subgroup analysis of birth modes in first and second twins showed a significantly poorer outcome in the cesarean section and combined delivery group (P < 0.05). The interdelivery time interval was significantly longer in the second twin cesarean section group (P < 0.01). There was no significant correlation between the interdelivery time intervals and Apgar scores (P > 0.05). Conclusion Although outcome parameters were significantly lower in second twins and twins born via secondary cesarean section, the clinical relevance of this appears to be negligible.

AbstractOur objective was to examine the neonatal outcome of second twins depending on presentation and mode of delivery. Using a database we analyzed the short-term neonatal outcome in twin pregnancies offered a trial of labor with special emphasis on the second twin depending on presentation and mode of delivery. Neonatal outcome was evaluated by Apgar scores, umbilical cord blood pH values, and perinatal or neonatal morbidity and mortality. Overall, in 219 (78%) of 281 pregnancies successful vaginal birth (VB) of both twins (VB–VB) was possible, 48 (17%) women had to be delivered by cesarean section (CS) of both twins (CS–CS), and in 14 (5%) women the second twin had to be delivered by CS after VB of the first twin (VB–CS). Successful VB was most common for vertex-vertex (V/V; n = 171, 82%) and vertex-nonvertex (n = 48, 75%) presentation (V/NV). Twins delivered by VB–CS had the lowest values for pHart (p = .006) and pHven (p = .010). pHart less than or equal to 7.00 values occurred only in second twins delivered VB–VB or VB–CS. Lower Apgar scores of the second twin occurred more frequently in the VB–CS and in the VB–VB than in the CS–CS groups (ps < .05). Lower levels of pHart (p = .002) and frequency of pHart less than or equal to 7.00 occurred more often in nonvertex second twins than in vertex second twins (p < .022). The high CS rate in V/NV presentation and the significantly worse perinatal short-term outcome of NV second twins after VB of the first twin underline that randomized studies are necessary to evaluate the best delivery mode for V/NV twins.

Follow Up Study

The adverse neonatal outcome is defined as the presence of birth asphyxia, respiratory distress, birth trauma, hypothermia, meconium aspiration syndrome, neonatal intensive care admission, and neonatal death. It is a major concern in developing countries, including Ethiopia. This study tried to identify predictors of adverse neonatal outcomes at selected public hospitals in Eastern Ethiopia. A hospital-based prospective follow-up study was conducted in three public hospitals in Eastern Ethiopia from June to October 2020. A total of 2,246 laboring women and neonates born at the hospitals were enrolled in the study. Data were collected through interviews, observation checklists, and clinical chart review. Reports were presented in relative risks with 95% CIs. The overall magnitude of adverse neonatal outcome was 20.97% (95% CI: 19.33- 22.71%). It was 24.3% for babies born through cesarean section (95% CI: 21.3%, 27.5). The presence of meconium in the amniotic fluid increased the risk for neonates delivered via cesarean section (ARR, 1.52 95% CI; 1.04, 2.22). Among neonates born via vaginal delivery, the risk of adverse neonatal outcome was higher among nullipara women (ARR, 1.42 95% CI; 1.02, 1.99) and among women diagnosed with abnormal labor or pregnancy such as APH, pre-eclampsia, obstructed labor, fetal distress, and mal-presentation at admission (ARR, 1.30 95%CI; 1.01, 1.67). The risk of adverse neonatal outcome was higher among babies born through the cesarian section than those born via vaginal delivery. Abnormal labor or pregnancy and being primiparous increased the risk of adverse neonatal outcome in vaginal delivery.

The onset of labor involves the action of multiple factors and recent reports have postulated the endocannabinoid system as a new regulator of this process. Our objective was to study the role of anandamide, one of the main endocannabinoids, on the regulation of placental molecules that contribute to the onset of labor at term. Placental samples were obtained from patients with laboring vaginal deliveries and from non-laboring elective cesarean sections. Vaginal delivery placentas produced higher prostaglandins levels than cesarean section samples. Besides, no differences were observed in NOS basal activity between groups. Incubation of vaginal delivery placentas with anandamide increased prostaglandins concentration and decreased NOS activity. Antagonism of type-1cannabinoid receptor (CB1) did not alter the effect observed on NOS activity. Conversely, incubation of cesarean section placentas with anandamide reduced prostaglandins levels and enhanced NOS activity, the latter involving the participation of CB1. Furthermore, we observed a differential expression of the main components of the endocannabinoid system between placental samples, being the change in CB1 localization the most relevant finding. Our results suggest that anandamide acts as a modulator of the signals that regulate labor, exerting differential actions depending on CB1 localization in laboring or non-laboring term placentas.

AbstractOur objective was to determine whether chorionicity affects umbilical cord blood acid-base parameters of the second twin. This was a retrospective cohort of twin pregnancies delivered at ≥23 weeks of gestation at a tertiary hospital from 2010 to 2016. Patients were included if arterial and venous umbilical cord gas results were available for both newborns and chorionicity was confirmed histologically. Exclusion criteria included intrauterine fetal demise of either twin prior to labor, major fetal anomalies, monoamnionicity, uncertain chronicity and twin-to-twin transfusion syndrome. The primary outcome evaluated was the umbilical artery (UA) pH of the second twin. A total of 593 dichorionic (DC) and 86 monochorionic (MC) twin pregnancies were included. No difference in UA pH was observed between MC and DC twins. Among vaginal deliveries (n = 97), the UA pH of the first twin was higher than the second twin (7.26 vs. 7.24; p = .01). Twin-to-twin delivery interval (TTDI) ≥20 min was associated with a higher UA pH in the first twin compared to the second twin (7.25 vs. 7.16, respectively; p = .006). Multivariable logistic regression was used to predict arterial pH < 7.20 for the second twin; the most predictive factors were arterial pH < 7.20 for the first twin, chronic hypertension and prolonged TTDI. Chorionicity was not associated with any acid-base parameter of umbilical cord blood in either the first or second twin. No differences in neonatal outcomes were observed based on chorionicity or birth order. Populations with a lower cesarean delivery rate may yield different findings.

AbstractTo evaluate the incidence of postpartum hemorrhage (PPH) and severe PPH via routine use of a pelvic drape to objectively measure blood loss after vaginal delivery in connection with PPH management.This prospective observational study was undertaken at the obstetrical department of the Charité University Hospital from December 2011 to May 2013 and evaluated an unselected cohort of planned vaginal deliveries (n=1019 live singletons at term). A calibrated collecting drape was used to meassure blood loss in the third stage of labor. PPH and severe PPH were defined as blood loss ≥500 mL and ≥1000 mL, respectively. Maternal hemoglobin content was evaluated at admission to delivery and at the first day after childbirth.During the study period, 809 vaginal deliveries were analysed. Direct measurement revealed a median blood loss of 250 mL. The incidences of PPH and severe PPH were 15% and 3%, respectively. Mean maternal hemoglobin content at admission was 11.9±1.1 g/dL, with a mean decrease of 1.0±1.1 g/dL. Blood loss measured after vaginal delivery correlated significantly with maternal hemoglobin decrease.This study suggests that PPH incidence may be higher than indicated by population-based data. Underbuttocks drapes are simple, objective bedside tools to diagnose PPH. Blood loss should be quantified systematically if PPH is suspected.

Abstract The appropriate time to restart anticoagulation in the postpartum period is not known. Both the American College of Obstetrics and Gynecology as well as American College of Chest Physicians (ACCP) have issued guidelines regarding the use of anticoagulants during pregnancy but neither have generated recommendations regarding the timing of the first dose of low-molecular-weight heparin (LMWH) in the postpartum period. The incidence of postpartum hemorrhage was assessed in a retrospective cohort study of 95 women treated with enoxaparin and compared with 303 consecutive deliveries where anticoagulation was not administered. The rate of severe postpartum hemorrhage did not differ significantly for women treated with peripartum enoxaparin versus a control group of women undergoing vaginal delivery (3.6% versus 1.4%, P=0.72) or cesarean section (5.1% versus 3.4%, P=0.98). There were no severe postpartum hemorrhages following the re-initiation of enoxaparin postpartum. In 75% of vaginal deliveries and 49% of cesarean sections, enoxaparin was restarted within 24 hours. Two incisional hematomas were observed in the group of women who received enoxaparin within 24 hours following cesarean section. We conclude that severe postpartum hemorrhage is an infrequent complication following the administration of enoxaparin postpartum. In support of current clinical practice, enoxaparin can be safely administered 0 to 24 hours following vaginal delivery and 12 to 36 hours following cesarean section.

The aim of this study was to analyze the comparative risks of this anal sphincter injury in relation to the type of intervention in vaginal delivery. We performed an observational, retrospective study of all vaginal deliveries attended at a tertiary university hospital between January 2006 and December 2009. We analyzed the incidence of obstetric anal sphincter injury for each mode of vaginal delivery: spontaneous delivery, vacuum, Thierry spatulas, and forceps. We determined the proportional incidence between methods taking spontaneous delivery as the reference. Ninety-seven of 4526 (2.14%) women included in the study presented obstetric anal sphincter injury. Instrumental deliveries showed a significantly higher risk of anal sphincter injury (2.7 to 4.9%) than spontaneous deliveries (1.1%). The highest incidence was for Thierry spatulas (OR 4.804), followed by forceps (OR 4.089) and vacuum extraction (OR 2.509). The type of intervention in a vaginal delivery is a modifiable intrapartum risk factor for obstetric anal sphincter injury. Tearing can occur in any type of delivery but proportions vary significantly. All healthcare professionals attending childbirth should be aware of the risk for each type of intervention and consider these together with the obstetric factors in each case.
