[Prostaglandins in the induction of labor at term with premature rupture of fetal membranes].

A prospective, randomized study included 389 pregnant women with normal pregnancy, gestational age of 37 weeks (259 days) in whom the delivery started by premature rupture of fetal membranes and without labor pains 6 or more hours after rupture of fetal membranes. The Bishop score was < or = 6 and there were no clinical or laboratory signs of infection before induction. The first group (n = 219) included pregnant women at term with premature rupture of fetal membranes and unfavourable pelvic score in whom labor was induced by intracervical dinoprostone.

[Delivery with vacuum extraction--indications, technique and complications].

[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.

[Risks for neonates born in the breech presentation].

A prospective study included 106 females and their newborns, 45 of them born in breech presentation and 61 delivered normally. The incidence of prepathologic and pathologic CTG records and meconial amniotic fluid is significant (0.01), more frequent in breech presentation (24.
