Abstrakt		Study objective: To confirm or reject the hypothesis that there is no significant difference in the occurrence of hypoxia at the onset of labour, in the course of labour and at delivery in term fetuses/newborns in breech presentation compared to those in vertex presentation. Design: Prospective controlled study. Setting: Division of Perinatology, Department of Obstetrics and Crynecology, University Medical Centre Ljubljana. Study population: Thirty-one infants in breech presentation and 28 infants in vertex presentation with gestational age 37 weeks or over, born after uncomplicated pregnancy and without evident malformations. Methods: At the onset of labour, fetal hypoxia was detected by determination of erythropoetin concentration in the amniotic fluid (>30 mU/ml) and indirectly by indices of hypoxia: pathologic cardiotocogram, oligohydramnion, pathologic index of Doppler blood flow velocity waveforms in the umbilical artery (RI>0.63, S/D>3) and meconium stained amniotic fluid. At the end of the first stage of labour fetal hypoxia was detected by the presence of acidemia in the mixed capillary blood of the presenting fetal part (pH<7.20). At delivery neonatal hypoxia was detected by acidemia present in the umbilical cord blood (pH<7.15), and/or by serum eiythropoetin level in the umbilical vein >50 mU/ml. Resutts: At the onset of labour the comparison in the incidence of hypoxia between fetuses in breech and vertex presentation yielded no significant difPerence. Only a few indices of hypoxia were more frequently present in breech than in vertex presenting fetuses, such as oligohydramnion and oligohydramnion with meconium and/or with erythropoetin level >30 mU/ml. At the end of the first stage of labour the difference in the occurrence of hypoxia between the two compared groups was again not statistically significant. (Abstract truncated at 2000 characters)
