다국어 초록 (Multilingual Abstract)

The Breech presentation is the most common mal-presentation. From Jan. 1963 to Dec. 1968, 455 cases of Breech presentation were delivered at Dept. of OB&Gyne. St. mary`s Hosp. Catholic Medical College. 1. The incidence of Breech presentation was 3.98% of all deliveries. 2. The most frequent age group was 25~29 years of age. 3. The most frequent incidence of gestation week was between 37 and 40. 4. Among them (breech presentation) only 39.6% of breech presentation was recieved antenatal care. 5. The most common type of breech presentation was incomplete breech. 6. In case of infant body weight, weighing more than 2,500gr fetal death was 5.7% and most frequently occured weighing 3,500~3,999gr in body weight. 7. Cord prolapse was 6.4% of all cases and most frequently occured in multigravida, premature, and complete breech. 8. Partial breech extraction was most common type of delivery and 50.6% of all cases. 9. C/S` was performed in 29 cases and 6.4% of all cases. 10. Post-partum hemorrhage was one of the most common maternal complicution, but among them no one lost blood more tham 1000cc in amount. 11. Three cases of clavicle fracture, one case of humerus fracture and one case of Erb`s palsy were occured as a fetal complication. 12. The causes of fetal death was immature and premature, 74% of all cases, and in cases of full term baby, asphyxia was 6.4%, brain damage was 3.3% and 16.3% of unknown causes. 13. According to the breech score index which was studied in Temple University Medical Center in 1967 for our 276 cases weighing more than 2,500grams of infant, breech score index was below 4 in almost all cases of poor progression of labor and prognosis. 14.There was a trend to the high score in lower body weight, lower score in high body weight as a consequence of index scoring by infant body weight. 15. Duration of labor was shorter in high score group than low score group.
