Low dose sulprostone for termination of second and third trimester pregnancies

Objective: The purpose of this study is to assess the effectiveness and safety of sulprostone (nalador®) for labour induction in the event of foetal death or foetal malformations. Study design: Retrospective analysis of 284 women with intrauterine foetal death (n=137), or foetal abnormalities (n=147), who underwent labour induction with sulprostone in a continuous dose of 1μg/min intravenously. Results: All but three women had a successful vaginal delivery. The median induction-expulsion interval was significantly shorter (12h) in the foetal death group compared to the foetal malformation group (25h). Two uterine ruptures were recorded, one in a woman with a uterine anomaly, and one in a woman with a previous caesarean section. There were no other complications. Gestational age had a significant influence on spontaneous expulsion of the placenta: before 24 weeks 55%, and after 24 weeks 82% spontaneous expulsion. For the chance of a neonate born with signs of life, parity was the only significant determinant. Conclusions: The use of intravenous sulprostone in a low continuous dose is both effective and safe. In addition, this study does not support former opinions that smoking and advanced maternal age are contraindications

Sulprostone for pregnancy termination in women with severe (pre-) eclampsia

Condensation: Sulprostone, used in a continuous low-dose intravenously, is effective for pregnancy termination. Caution is necessary when using this drug in severely preeclamptic patients. Objective: To evaluate the safety and efficacy of induction of labor with a prostaglandin analogue in women with severe (pre-) eclampsia. Study Design: A retrospective analysis of a 12-year cohort in which labor was induced in women with severe (pre-) eclampsia with sulprostone (a prostaglandin E2 analogue) in a continuous intravenous low-dose intravenous dose of 1 μg/min. Results: In 30 severely preeclamptic and one eclamptic women, labor was induced on maternal indication with sulprostone. The median gestational age at induction was 28 weeks (range 16-37 weeks). The fetuses were either dead (n = 19) or considered not viable (n = 12). All women delivered vaginally after a median induction -expulsion interval of 14 hr (range 6-57 hr). In all but one woman, a delivery was achieved within 37 hr. Two of the nine women who suffered dyspnea at the time induction was started, experienced deterioration during infusion of sulprostone. In one of these women, infusion had to be discontinued after 2 hr. and the pregnancy was terminated by dilatation and evacuation. One woman gave birth after 57 hr of sulprostone infusion. We did not observe any cardiovascular complications. All but one woman recovered after pregnancy termination: a severely eclamptic woman died 10 days after delivery, after developing adult respiratory distress syndrome, sepsis and multiple organ failure. Conclusion: Sulprostone, in a continuous low-dose intravenously, is effective for termination of pregnancy in the critically ill preeclamptic woman. Our study, including two patients with serious deterioration of pulmonary function during and one maternal death after induction, does not permit definitive conclusions regarding the safety in these patients

Association between colonization with Group B Streptococcus and preterm delivery: A systematic review

Up to 36% of pregnant women are colonized with Group B Streptococcus (GBS). Preterm delivery in colonized mothers is a risk factor for early onset neonatal GBS disease, but whether maternal GBS genital colonization is related to preterm delivery is unclear. The objective of this review was to determine the relationship between maternal colonization with GBS and preterm delivery. Pubmed searches and reference lists of all selected publications were used to find studies reporting on the relationship between maternal GBS colonization and preterm delivery. Study characteristics were abstracted, and validity scores were performed. To assess the relationship between GBS colonization and pregnancy outcome, four-fold prognostic tables were constructed for each study. Out of more than 60 full-text articles, 16 follow-up studies and four case control studies were included in this review. Follow-up studies were divided into 'cohort studies,' in which cultures were taken early in pregnancy and which reported on pregnancy outcome, and 'cross-sectional studies', in which cultures were collected during delivery. Studies differed widely in methods, validity score, and GBS prevalence. The combined estimate from a random effect meta-analysis of the 11 cohort studies was 1.06 (95% confidence intervals (CI) 0.95-1.19) and for the five cross-sectional studies 1.75 (95% CI 1.43-2.14). For the case control studies, the pooled odds ratio was 1.59 (95% CI 1.03-2.44). This systematic review did not show an association between maternal GBS colonization during pregnancy and preterm delivery. However, in case of preterm delivery, there is an increased risk of subsequent maternal GBS colonization
