Abstract

ABSTRACT: Objective : The aim of this study was to reduce the rate of cesarean section (CS) in severe pregnancy-induced hypertension (PIH) by introducing a set of indicative criteria for CS. Methods : Labor induction was attempted in Japanese patients ( n = 41) with severe PIH after 34 weeks of gestation. Vital signs and symptoms that may increase the risk of serious complications were defined. Following the appearance of one or more signs or symptoms, labor induction was suspended and CS was performed. The impact of using specific indicative criteria was evaluated by comparing the CS rate among patients who delivered before and after the criteria were introduced. Results : Labor induction was attempted in 36 of 41 patients. Among the 36 patients in whom vaginal delivery was started, 12 patients required CS, and the remaining 24 patients succeeded in vaginal delivery. The introduction of specific indicative criteria for CS was associated with a significant reduction in the CS rate, from 95% (43/45) to 41% (17/41). Conclusions : Unnecessary CS may be avoided by defining the limits of safe labor induction.
