Objective: To describe the duration of expectant management and the indications for termination of expectant management of pregnancies complicated by severe pre-eclampsia remote from term.
Study design: We identified pregnancies complicated by severe pre-eclampsia diagnosed between 24 weeks and 31 weeks 6 days at our institution in 1991-98. Pertinent clinical data were obtained from review of maternal and neonatal charts. Comparison of patients was based on the duration of time from admission to delivery: < 48 h (group 1), 48 h to 7 days (group 2), and > or = 7 days (group 3).
Results: A total of 142 women met all study criteria. Seventy-nine (55.6%) women were delivered within 48 h, 42 (29.6%) between 48 h and 7 days, and 21 (14.8%) at > or = 7 days from diagnosis. Of group 1 patients (< 48 h), 59 (74.7%) were delivered for maternal indications while 20 (25.3%) were delivered for fetal indications. Of group 2 patients (48 h to 7 days), 35 (83.3%) were delivered for maternal indications while seven (16.7%) were delivered for fetal indications. Of group 3 patients (> or = 7 days), 16 (76.2%) were delivered for maternal indications while five (23.8%) were delivered for fetal indications. There were no significant differences in the indications for delivery based on the duration from admission to delivery.
Conclusions: Despite an aggressive approach towards expectant management of preterm pregnancies complicated by severe pre-eclampsia, most patients were delivered within 48 h for maternal indications.
