[Induction of labor using endocervical administration of dinoprost in post-term pregnancy].

The authors analyzed results of 295 labors induced with endocervical application of dinoprostin (152 term- and 143 postterm labors) in relation to 242 (125 term- and 117 postterm-) spontaneous labors. Delayed labor increases the occurrence of meconial amniotic fluid (21.96%:9.03% p < 0.01), and pathological and prepathological CTG records (23.85%: 11.97% p < 0.005). In addition, children show lower Apgar score (p < 0.001), and among them there are more hypertrophic (6.54%:2.53% p < 0.05), postterm (6.92%:0.0% p < 0.005), and dysmature children (11.92%:3.12% p < 0.01) when compared to children born between the days 274 and 287 of the gestational age. Perinatal morbidity of children born after 287 gestational days in rather high-32.31%. Induction of labor with endocervical application of prostine shortens the duration of the labor (p < 0.001). Large numbers of labors are finished with vacuum extraction-3.73% (3.29% of term- and 4.19% of postterm labors) and cesarear section-12.88% (10.53% of term- and 15.38% of postterm labors) usually due to dystocia of the uterus and hypoxion of the neonate. Labor trauma is the most usual trauma among perinatal problems of new born infants delivered by the induction with prostaglandins and high perinatal morbidity rate is due not only to the induction method but also to the incorrect assessment of the gestational age.
