In recent years, the use of cesarean section has increased rernarkably, because of the emphasis that is directed toward recognition of impairment of fetal well-being. We studied on 370 patients who had cesarean section among 2481 deliveries at Gill Hospita1, Inchon, during one year period from Jan. first to Dec. 3lst l980. The results analysed were as follows: 1. 0verall incidence of cesarean section was l4.9% of the total deliveries, 2481 patients. 2. of all these 370 sections, the primary section accounted for 76.2% of the sections and the repeat sections were 23.8%. 3. The most frequent indication of the cesarean section was cephalopelvic dispropo rtion (3l.0%). Next indication were repeat (23.8%) and antepartum bleeding (10.9%) 4. The most frequent indication for primary section in multipara was henrorrhage such as placenta previa and abruptio placentae (37%). Next were malpresentation (l4.8%) and CPD (ll.l%). 5. By age, 42.8% of cases were between 25~29 years of age, below l9~-0.5% and over 40~-0.5%. 6. In the boty weight distribution of infants, the group of 3000~3499 gm was the most common (37.6%). 7. In performing the cesarean section, lower cervical transverse incision was most common (94%). Classical section was only 5 cases (l.4%) and extrapsritoneal section-7 cases(1.9%). Also cesarean hysterectomy was performed in 10 cases(2.7%). 8. Incidental operation; Tubal ligation for sterilization was most common (75.5%). The others were cesarean hysterectorny (l0.2%) and appendectomy (9.1%) etc. 9. The type of the anesthesia in cesarean section was general (99.2%) and spinal (0.8%). The epidural anesthesia was not performed in section except the vaginal delivery. 10. Of the postoperative complication, the wound infection was the most common (31.2%). The others were urinary tract infection (20.8%), endometritis (18.8%) etc. ll. There was high rate of maternal morbidity in patients with anemia(l3.0%). l2. The perinatal mortality was 4.6%. l3. There was only one maternal death (0.27%) in 370 cases of cesareans
