RESUMEN
Background: Although shorter labors are the benefits of Early Amniotomy (EA), it may lead to risks such as non-reassuring fetal testing and cesarean delivery. Also, the effect of cervical ripening to induce labor before amniotomy is unknown. This systematic review and meta-analysis evaluated the effect of EA on the delivery outcome with or without cervical ripening. Materials and Methods: Bibliographic search was conducted without time limit until June 2020. PubMed, Scopus SID Magiran, Cochrane Library Science website, and ISI databases were searched with English and Farsi keywords, including amniotomy, delivery, induced, and pregnancy outcome. Results: The meta-analysis on ten clinical trials showed that the incidence of cesarean section was lower (0.89% VS 0.94; relative risk, 0.85; 95% confidence interval, 0.55-1.30) compared to the group without cervical ripening, and the time to induce labor was approximately 55 minutes (mean difference, 0.91 hour; 95% confidence interval, -1.43 to - 0.33). Conclusions: If EA is performed in women after cervical ripening, the incidence of cesarean section will not increase, and the duration of labor will be reduced. A shorter delivery time is associated with perinatal benefits and greater maternal satisfaction. Furthermore, EA with cervical ripening may reduce monitoring time in busy hospitals with limited medical staff.
RESUMEN
BACKGROUND: Post-partum hemorrhage (PPH) is a common cause of maternal mortality in developing countries. This trial was conducted to study the effectiveness and safety of rectal misoprostol for PPH. AIM: To assess the effectiveness and safety of misoprostol and comparing with oxytocin for prevention of PPH. MATERIALS AND METHODS: Women were randomized to receive either two 200 µg rectal misoprostol tablets (study group) or 20 units oxytocin in 1000 cc normal saline intravenously (control group). The outcomes were incidence of PPH, amount of blood loss, duration of labor, incidence of side effects, pre- and post-delivery hemoglobin, and use of additional uterotonics. FINDING: The incidence of PPH was 12% in the study group and 10% in the control group (P > 0.05). No significant difference was observed between the groups hematocrit (P > 0.05). Other variables including severe PPH and duration of the third stage of labor were similar in both groups. CONCLUSION: Rectal misoprostol was as effective as intravenous oxytocin for preventing post-partum hemorrhage with the same incidence of side effects and is recommended to be use as an uterotonic agent to manage third stage of labor routinely.
