Perinatal mortality and morbidity in breech presentation

Abstract

The perinatal mortality associated with breech presentation at the Royal Women's Hospital, Melbourne, between 1974 and 1976 was 10.4%, or almost 5 times the overall hospital figure. Nine of 487 infants (1.8%) weighing greater than or equal to 2500 g died in the perinatal period, but 7 were already dead at the onset of labor or had congenital abnormalities incompatible with life. Sixty of 177 infants (33.9%) weighing 1000-2499 g died in the perinatal period, but 28 of these died due to prematurity alone or from complications of intrauterine hypoxia or birth trauma. Although elective cesarean section for breech presentation could not be justified for infants weighing greater than or equal to 2500 g, this procedure may well reduce the perinatal loss of premature infants by reducing the incidence of intrauterine hypoxia and preventing birth trauma.
