[Critical notes on delivery and perinatal mortality in single breech presentation deliveries].

This report deals with 432 single breech presentation deliveries. Caesarean section frequency was 12,3%. As to the vaginal route of delivery, the simple Bracht manoeuvre had been prefered; in recent times, however, the assisted spontaneous delivery with oxytocin-infusion has been introduced. The corrected perinatal mortality was 4,9%. The rate of prematurely born infants amounted to 14,6%. The corrected perinatal mortality of infants up to 2500 g was 3,3%; of full term infants it was 1,4%. The importance of breech presentation delivery as a high risk delivery is being emphasized. Fetal monitoring and blood gas analysis were required. Indications of caesarean section and suggestions for the management of breech presentations were established. Generally caesarean section of primiparae is not recommended. The diminished rate of prematurely born infants is considered to be of great importance for the decrease of perinatal mortality of breech presentation infants. Intensive pregnancy care, widely used uterotocolysis, and cervix-cerclage in cases of breech presentation are recommended.
