[Inductoconduction with unfavorable cervix. PGE2 plus oxytocin for the induction of labor in complicated pregnancies]. / Inductoconducción con cervix desfavorable. PGE2 más oxitocina para inducir trabajo de parto en embarazos complicados.

To evaluate intracervical PGE2 plus low dose oxytocin in the induction of cervical changes and labor, we studied 36 pregnant patients who had one of the following complications: Intrauterine death, anencephaly, gestational trophoblastic disease, missed abortion and PRM with pregnancy less than 28 weeks of gestational age. 200 mcgs of PGE2 were applied in the cervix, and immediately an oxytocin infusion was started at 2 mlU, the dose of oxytocin was increased in the arithmetic fashion until labor was started. The latency between the application of PGE2 and the beginning of labor was 3.57 +/- 3.29 h., between the beginning of labor and birth was 5.59 +/- 3.39 h. The cervix changed from a Bishop score of 2.1 +/- 1.5 to 6.2 +/- 1.8 (p less than 0.0001). The hospital stay was of 1.6 +/- 0.6 days. The secondary affects were minimal, and the births were all vaginal.
