RESUMEN
OBJECTIVES: The aim of this study is to assess the procedure-to-delivery interval (PDI), the obstetric complications, and the early neonatal outcome in patients that did or did not receive glucocorticosteroids (GCSs) before third-trimester amniocentesis (TTA). METHODS: A retrospectively analysis of 445 TTA procedures divided into two groups based on the administration (study group = 220 patients) or not (control group = 225 patients) of GCSs before TTA. The PDI was calculated for all patients. Obstetric and neonatal outcomes were compared between the groups. RESULTS: The rate of procedure-associated complications was similar between the groups. The mean PDI was 47.2 ± 16.8 days. The overall incidence of preterm birth was 11.7%; 9% delivered between 34 and 37 weeks and 2.7% between 28 and 34 weeks. Only nine patients (2%) delivered within seven days following TTA. The incidence of respiratory distress syndrome in the study and control groups was 1.8% and 1.3%, p = .71, respectively. There were no significant differences in other neonatal outcomes in term and preterm deliveries between the study and control groups. CONCLUSIONS: In the present study, the administration of glucocorticoids prior to TTA did not reduce the rates of neonatal complications, which was similar in both groups and not higher than the general population.

OBJECTIVE: To identify risk factors for increasing severity of OASI and evaluate its possible correlation with two known risk factors-birth weight (BW) and neonatal head circumference (HC). METHODS: We performed a retrospective cohort study at a university affiliated hospital between 2003 and 2019. We compared five groups of patients - according to presence and degree of perineal laceration - 3a, 3b, 3c and 4 and patients without OASI. Additionally, four parameters were defined to assess their relation to the severity of OASI: (1) BW ≥ 90th and HC < 90th percentiles; (2) BW < 90th and HC ≥ 90th percentile; (3) BW and HC ≥ 90th percentile and (4) BW and HC < 90th percentiles. RESULTS: During the study period, 150,221 deliveries were evaluated. Parturients were allocated according to OASI severity - 455 patients had a 3rd (3a, 3b or 3c) or 4th degree perineal tear, while 110,966 patients had no OASI. Allocation to subgroups according to offspring anthropomorphic measures showed that as fetal size parameters increased, the rate of more severe tears increased, particularly in women delivering neonates with HC ≥ 90th percentile. Multinomial regression analysis was performed for each 3rd degree OASI subgroup. This analysis demonstrated the odds for OASI gradually increase with tear severity for BW ≥ 90th percentile and the combined BW and HC ≥ 90th percentile parameters, as compared with neonates with HC and BW < 90th percentile. CONCLUSIONS: Birth weight and head circumference above the 90th percentile are correlated with increased degree of OASI severity.

BACKGROUND: Candidates for trial of labor after cesarean must be carefully screened to maximize success and minimize morbidity. Demographic and obstetric characteristics affecting success rates must be delineated. OBJECTIVE: We examined whether the labor stage of the primary delivery in which a woman underwent an unplanned cesarean delivery would affect the likelihood that she could achieve a subsequent vaginal birth. STUDY DESIGN: Electronic medical records-based study of 676 parturients. Trial of labor rates and outcomes were compared between women whose primary cesarean delivery was performed in the first vs. the second stage of labor. SETTING: Hadassah Medical Center, Israel POPULATION: Women in their second pregnancies, with singleton fetuses, who underwent unplanned cesarean delivery in their first pregnancy and elected trial of labor in the second delivery. The main outcome measures were maternal and neonatal complications and vaginal birth rates in first vs. second stage of labor groups. RESULTS: In our population, 76 % of women attempt trial of labor after cesarean. Rates of successful vaginal delivery did not differ significantly between those who underwent primary cesarean in the first vs. second stage of labor: 67.4 % vs. 70.2 %, p = 0.483, respectively. Among women whose primary UCD was in the second stage, only 18.2 % (35/192) required a UCD in the second stage in the subsequent delivery, while 58.9 % (113/192) underwent UCD in the first stage in both deliveries. CONCLUSION: Labor stage of the primary unplanned cesarean delivery, should not dissuade women from a trial of labor after cesarean in their second delivery.
