Use of misoprostol on an outpatient basis for postdate pregnancy.
OBJECTIVE
Within the obstetric community, several studies suggest that cervical ripening and labor induction after 40 weeks' gestation leads to improved maternal and neonatal outcomes. The most effective drug regimen to safely promote labor has not been determined.


METHODS
Forty-nine subjects followed in an outpatient obstetrical clinic with pregnancies of at least 40 weeks' gestation, and an unfavorable Bishop score were assigned randomly to receive oral misoprostol 50 or 25 microg every 3 days for a maximum of three doses.


RESULTS
Twenty-three subjects received misoprostol 25 microg and 26 received 50 microg. The mean interval (+/-standard deviation) from start of cervical ripening to delivery was 2.4 days +/-0.3 vs. 3.9 days +/-0.7 for the 50 and 25 microg groups (P<0.05). No adverse events were noted. However, due to small sample size, less frequent adverse events may be missed. Type II errors cannot be excluded.


CONCLUSIONS
In the prevention of postdate pregnancy, outpatients use of oral misoprostol 50 microg appears to result in earlier delivery, as compared to 25 microg.
