AbstractFrom 1959 to 1975, 1060 (3.6%) breech presentations were found among 29,463 infants. The breech deliveries from May 1, 1959 to December 31, 1965 were compared with those from January 1, 1966 to December 31, 1975. Among the 3.6% breech deliveries there were 47% male and 53% female. There were more primigravida breech deliveries in both groups. The mean age of the mothers was 25.4 years for primigravidas and 29.4 years for multiparas. There was a maternal mortality of 0.2% (2 cases) in breech delivery. 29% of the breech deliveries were premature deliveries. There was a strickingly high incidence of frank and full breech deliveries among all patients. Knee presentations were rare. Delivery was primarily accomplished with the Bracht manoeuver in over 80% of the cases. Complete breech extractions decreased and the incidence of Caesarean Sections rose from 6% in the first group to 21% in the second group of patients. During the past 3 years the Caesarean Section rate was approximately 30%. Perinatal complications in the breech deliveries compare well to those reported in the literature. Of 750 mature infants (70.8%), 12 died (1.6%). Discounting children with congenital malformations and intrauterine stillbirth there remained 5 deaths from breech deliveries (0.7%). Of 1032 breech deliveries with a birth weight of 1000 grams or over, 74 infants (over all perinatal mortality 7.2%) died. 110 infants of all breech deliveries had a birth weight of less than 2500 grams (prematurity rate 29.2%). Of 102 cases of perinatal mortality in breech deliveries including those below 1000 grams 90 (88.2%) were premature. Of those 90 premature deaths, 28 infants were less than 1000 grams. 25 infants showed fetal congenital abnormalities. The corrected perinatal mortality of the premature deliveries was therefore 11.9%. The rate of birth trauma was 6.3% in the first group and 2.7% in the second group.
