The study discusses the frequency of operative obstetric deliveries (cesarean section, forceps extraction and vacuum extraction) over a period of 18 years from 1976 till 1993. A total of 100,545 deliveries with 100,192 livebirths took place during this period with a decrease of the annual number of deliveries in the last years. The frequency of the various kinds of operative deliveries shows different tendencies. The frequency of cesarean section has increased from 4.87 per cent in 1976 to 19.58 per cent in 1993, this increase being particularly marked during the last 6 years. Meanwhile the vaginal operative deliveries have decreased their frequency. The decrease of forceps extraction is from 4.33 to 2.22 per cent (steadily about 2 per cent during the last years). The frequency of vacuum extraction has dropped from 1.89 per cent to 0 by the end of the 1980 and the beginning of the 1990. The tendencies of the development of obstetric operations are analysed as well as their influence on perinatal outcome.
