Evaluation of Suzor forceps training by studying obstetric anal sphincter injuries: a retrospective study.

BACKGROUND: Instrumental deliveries are an unavoidable part of obstetric practice. Dedicated training is needed for each instrument. To identify when a trainee resident can be entrusted with instrumental deliveries by Suzor forceps by studying obstetric anal sphincter injuries. METHODS: A French retrospective observational study of obstetric anal sphincter injuries due to Suzor forceps deliveries performed by trainee residents was conducted from November 2008 to November 2016 at Limoges University Hospital. Perineal lesion risk factors were studied. Sequential use of a vacuum extractor and then forceps was also analyzed. RESULTS: Twenty-one residents performed 1530 instrumental deliveries, which included 1164 (76.1%) using forceps and 89 (5.8%) with sequential use of a vacuum extractor and then forceps. Third and fourth degree perineal tears were diagnosed in 82 patients (6.5%). Residents caused fewer obstetric anal sphincter injuries after 23.82 (+/- 0.8) deliveries by forceps (p = 0.0041), or after 2.36 (+/- 0.7) semesters of obstetrical experience (p = 0.0007). No obese patient (body mass index> 30) presented obstetric anal sphincter injuries (p = 0.0013). There were significantly fewer obstetric anal sphincter injuries after performance of episiotomy (p <  0.0001), and more lesions in the case of the occipito-sacral position (p = 0.028). Analysis of sequential instrumentation did not find any additional associated risk. CONCLUSION: Training in the use of Suzor forceps requires extended mentoring in order to reduce obstetric anal sphincter injuries. A stable level of competence was found after the execution of at least 24 forceps deliveries or after 3 semesters (18 months) of obstetrical experience.

Vaginal screening for group B streptococcus using PCR in pregnant women with unknown colonization status: Impact on newborn monitoring for early-onset sepsis.

BACKGROUND: Early-onset neonatal sepsis represents a diagnostic challenge, as it is a cause of neonatal mortality and morbidity. Guidelines for the prevention of group B streptococcus (GBS) infection recommend that all pregnant women must be screened for GBS carriage at the end of pregnancy, with intrapartum antibiotic prophylaxis being provided for GBS carriers. If vaginal culture is not available, GBS polymerase chain reaction (GBS-PCR) is an alternative option for this type of screening. In our unit, GBS-PCR is performed when pregnant women present to the delivery room with ongoing labor and with no results of culture GBS screening available. The main objective of this study was to evaluate the impact of the results of GBS-PCR on monitoring modifications in newborns of mothers with unknown GBS status. The secondary objectives were to confirm the feasibility of a GBS-PCR-based screening method in everyday practice and to evaluate the impact of GBS-PCR results on the modification of intrapartum antibiotic therapy in pregnant women. METHOD: A retrospective, single-center, observational study was conducted for 1 year. For dyads with GBS-PCR performed, changes concerning intrapartum antibiotic therapy and the newborn's monitoring were recorded. The feasibility of the method was evaluated by the delay between the GBS-PCR realization and the availability of the result; in addition, the number of GBS-PCR tests that could not be realized were collected. RESULTS: Overall, 60 GBS-PCR samples were tested for 60 pregnant women. Results were obtained for all samples, and the median duration to obtaining the GBS-PCR results was 70 min (60.8-87.2). These results were positive for 11 (18.3 %) women and led to monitoring modifications for two infants. In total, 27 pregnant women (45 %) had modifications in their antibiotic therapy due to the GBS-PCR results. CONCLUSION: GBS-PCR was quickly available and the results led to changes in maternal antibiotic prophylaxis and in the monitoring level of the newborns.

Comparative study of dinoprostone and misoprostol for induction of labor in patients with premature rupture of membranes after 35 weeks.

The modalities of induction of labor in the event of premature rupture of membranes are controversial. The main purpose of this study was to compare the modalities of delivery after the use of dinoprostone or misoprostol for labor induction in the preterm rupture of membranes after 35 weeks in women with an unfavorable cervix. We then studied maternal and fetal morbidity for the two drugs. Retrospective, single-center, comparative cohort study in a level 3 maternity unit in France from 2009 to 2018 comparing vaginal administration of misoprostol 50 µg every six hours (maximum 150 µg) and administration of dinoprostone 10 mg, a slow-release vaginal insert, for 24 h (maximum 20 mg), for labor induction in the preterm rupture of membranes after 35 weeks in women with an unfavorable cervix (Bishop score < 6). We included 904 patients, 656 in the misoprostol group and 248 in the dinoprostone group. Vaginal delivery rate was significantly higher in the dinoprostone group (89% vs. 82%, p = 0.016). There were more cesarean sections for abnormal fetal heart rate in the misoprostol group (p = 0.005). The time interval from induction to the beginning of the active phase of labor and the duration of labor were shorter in the misoprostol group than in the dinoprostone group (437 min vs. 719 min, p < 0.001 and 335 min vs. 381 min, p = 0.0023, respectively). Maternal and neonatal outcomes were not significantly different in the two groups. Vaginal dinoprostone used for labor induction in preterm rupture of membranes seems to be more effective for vaginal delivery than vaginal misoprostol (50 µg).
