title: New trends in cesarean section.
abstract: The Authors studied the frequency of Cesarean section in relation to deliveries in the last trimester of pregnancy, the frequency of repetitive Cesarean section, age and parity of the patients, indication for cesarean section, week of delivery, and perinatal and maternal morbidity and mortality at the First Clinic of Obstetrics and Gynecology, University of Catania, Catania, Italy, from 1972 to 1974 and from 1983 to 1985. The frequency of Cesarean section has increased from 12.07% (735 cases out 6,086 deliveries) to 16.89% (837 cases out of 4,955 deliveries). There was a decrease in frequency of repetitive Cesarean section from 30.47% (224 cases) to 27.95% (234 cases) and in perinatal mortality rate from 4.35% (32 cases out of 735) to 3.19% (27 cases out of 845 newborn). There were no cases of maternal death, while the most common cause of maternal morbidity was uterine atonia. From 1972 to 1974 mechanical causes were the most frequent indication for Cesarean section (28.16% -207 cases), while from 1983 to 1985 previous hysterotomy (32.73% -274 cases) was the main indications for Cesarean section.
