[The large fetus--its obstetrical management and the results].

To find the maternal-fetal outcome 98 pregnancies with fetal weight over 4000 g have been observed. For the period 1993-1994 the rate of large fetus was 2.76%, 0.84% of which were over 4500 g. The second period of delivery was prolonged in 9.7% of all primigravidas. The registered shoulder dystocia and perineal lacerations of the mother were related to increasing birthweight. Difficult deliveries resulting in clavicle fracture or brachial plexus injuries and facial trauma. Fetal distress was observed in 7.14%. Congenital anomalies were not increased in the group of the large fetus. No maternal death was registered. The strict observation of the pregnant for latent diabetes mellitus and anticipation of the potential complications associated with delivery of a large infant may reduce maternal and neonatal morbidity rates and maintain low mortality rates.
