The objective of this investigation was to determine the frequency, indications and complications of cesarean section performed at Hospital Central Militar (HCM). A prospective open study was performed during 2 years, 6977 pregnant women were included, of these, 5,105 patients (73.16%) had vaginal delivery and 1,872 (26.84%) cesarean sections were performed. The most frequent indications were failure to progress in labor (29.87%), repeated cesarean sections (22.86%) and breech presentation (9.61%). Endometritis was the major cause of positive morbidity (13.24%). Cesarean section rate had a significant increase of 11% in a 12-year period (1982 through 1994), almost of 1% annual. Attempt should make to halt the rise by marking recommendations as vaginal delivery after a previous cesarean section, breech deliveries. Also it is necessary to use appropriate intrapartum electronic fetal heart rate monitoring to avoid increased rates of unnecessary intervention.
