Perinatal mortality and morbidity in breech presentation. 1979

L J De Crespigny, and R J Pepperell

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.

D007744	Obstetric Labor Complications	Medical problems associated with OBSTETRIC LABOR, such as BREECH PRESENTATION; PREMATURE OBSTETRIC LABOR; HEMORRHAGE; or others.

D007746	Labor Presentation	The position or orientation of the FETUS at near term or during OBSTETRIC LABOR, determined by its relation to the SPINE of the mother and the birth canal. The normal position is a vertical, cephalic presentation with the fetal vertex flexed on the NECK.

D001946	Breech Presentation	A malpresentation of the FETUS at near term or during OBSTETRIC LABOR with the fetal cephalic pole in the fundus of the UTERUS. There are three types of breech: the complete breech with flexed hips and knees; the incomplete breech with one or both hips partially or fully extended; the frank breech with flexed hips and extended knees.
