Labor induction for the preterm severe pre-eclamptic patient: is it worth the effort?

Objective: The purpose of this study was to examine the success rate of labor induction in patients with severe pre-eclampsia delivered at h 34 weeks' gestation; to identify factors associated with its success; and to evaluate neonatal outcomes based on induction success or failure. Methods: We identified pregnancies complicated by severe pre-eclampsia delivered at h 34 weeks' at our institution from 1991 to 1998. Women who underwent labor induction and had successful vaginal delivery were compared to those who underwent labor induction, but required Cesarean delivery. Multiple logistic regression analyses were performed to assess factors associated with successful induction and neonatal outcome. Results: Over the 7-year study period, there were 215 patients meeting the criteria. Sixty-four (29.8%) did not undergo a labor attempt; 69 of 151 (46%) women who underwent labor induction achieved vaginal delivery. Labor induction was successful in 0%, 6.6%, 35.3% and 68.5% of cases at 24-26, 27-28, 29-3...
