Management of post-date pregnancy: a case control study.

Post-date pregnancy is associated with higher rates of perinatal mortality and morbidity. The purpose of the present study was to compare the outcome of 200 post-date pregnancies, managed according to our protocol, to a matched control group of 200 healthy pregnant women delivered at term. The management protocol was based mainly on the pelvic score and nonstress test. Higher rates of labor induction, meconium-stained amniotic fluid, fetal distress, instrumental deliveries and cesarean sections were found in post-date pregnancies than in the control group (40% vs. 3% P = 0.0001, 31% vs. 15.5% P = 0.00001, 18.5% vs. 9.5% P = 0.007, 8% vs. 3% P = 0.02, 12.5% vs. 4% P = 0.002 respectively). Neonatal birth weight in the study group was significantly higher than in the control group (3,484.3 +/- 410.7 vs. 3,218.4 +/- 407.8 g P less than 0.001). Despite these differences between the groups, the perinatal morbidity and mortality rates were similar. These results can be partially attributed to the early antenatal monitoring and intensive follow-up.
