Caesarean section: a 15-year review of changing incidence, indications, and risks

During 15 years (1965 through 1979), 9,718 cesarean sections were performed at Hutzel Hospital. This report concerns the indications, incidence, morbidity, and mortality. Dystocia, fetal distress, and breech presentations were the most common indications for primary cesarean section. The incidence rose from 9.8% to 16.8% during this study. Forceps deliveries dropped from 47.5% to 12.0% and vaginal breech deliveries decreased from 86% to 35%. Spinal anesthesia was used in 90%. Caesarean section hysterectomies were performed in 128. The most common indications were carcinoma in situ of the cervix, uterine leiomyoma, and hemorrhage. Puerperal sepsis and urinary tract and wound infections were the major causes of morbidity. Perinatal mortality decreased from 40% to 29%. There were 10 maternal deaths. Sepsis was the major cause of death. At least four deaths could have been avoided if ultra-high-risk patients had not been pregnant in the first place.
