A cross-sectional, prospective and analytical study was conducted at “Justo Legón Padilla” Provincial Gynecoobstetric Hospital, in Pinar del Rio, from June to November, 1996, to compare some aspects of labor induction by prostaglandins, oxytocin or both. All the patients that underwent labor induction were studied: 407 with oxytocin; 34 with misoprostol and 19 with the combination of both drugs. The following variables were analyzed: incidence by months, drugs used, gestational age, cause of induction, birth way, characteristics of the amniotic fluid and Apgar score. The results were grouped into tables and a statistical analysis was made by percentage and chi square test with a significance level of p < 0.05. The main results were: a total index of inductions of 14.7 % in the studied period and their main causes in general were arterial hypertension, premature rupture of the ovular membranes, oligohydramnios and prolonged pregnancy. In the preterm birth the main causes were arterial hypertension, premature rupture of the ovular membranes and induced abortion by genetic cause. There was a high index of cesarean sections (33.4 %) and the fundamental causes were acute fetal suffering (35.1 %) and cephalopelvic disproportion (23.4 %). The intensification of the meconium (labor vs birth) was observed in 30 % when oxytocin was used alone and in 14 % when only prostagalandins were used. There were no significant differences in the Apgar score of the newborn infant on comparing the different induction methods used.
