Breech presentation is the most frequent abnormal one, and it causes severeal complication during labor such as prematurity, low birth weight, congenital anomaly, increased C-section rate and increased perinatal morbidity. We studied 411 cases of breech delivery, including 364 of single and 47 cases of multiple preg., at the Kwangju Christian Hospital during five and half years from January 1975 to June 1980. The results were as follows: 1. The incidence of breech delivery was 3.39%. 2. Most patients were between 25 and 29 yars old. The incidence was increased in women over 40, or whose parity was more than 5. 3. In 74.02% of patients delivery occurred between 38-42 weeks of gestation and 22.38% of the neonates weighed less than 2500 gm. 4. Regarding the type of breech, the most common was Frank (41.62%); and the others were incomplete(34.32%); unclassified (22.37%); and complete (1.69%). 5. The duration of labor averaged 10.69 hours in primipara and 6.42 hours in multipara, without significant difference among the types of breech pregentation. 6. The incidence of PROM was 16.79%(69 patients), and was lowest in incomplete breech presentation(14.89%). 7. The incidence of cord prolapse was 5.11%(21 patients), and in 85.7% (18 patients) it was incomplete. 8. The mode of delivery were PBE, (50.4%); (24.6%); TBE, (22.8%); and spontaneous, (2.2%). 9. The incidence of C/S for nullti-para increased slightly year by year except for 1980. 10. The incidence of congenital anomaly was 2.7%. 11. The perinatal mortality was 16.7% and the leading cause was prematurity. 12. Apgar score was 7.89 for vaginal delivery and 9.45 for C-section.
