title: [Cesarean section frequency and its indications at the State University Hospital Maternity Home over a 12-year period].
abstract: The aim of this retrospective study is to analyse the tendency of change of the rate of CS and the indications for them. The data are taken from the hospital medical documentation. For each year is determine the rate of CS and the indications. Only the first two leading indications are taken because next are most often consequence or subgroup of them. The incidence of each indications is calculate on the sum of this indications from different cases to the sum of indications from all CS. From 1986 to 1997 year there were 49,855 deliveries and 9384 CS. CS rate at 1986 was 13.9 and increased to 24.0 at 1997 year. The mean CS rate for the period is 18.75. The leading indications are: dystocia (39.2%), previous CS (20.9%), fetal distress (16.9%), breech presentation (14.6%). In more than half of CS in the leading indication there are relative indications. For the period there is significant tendency of decrease of the indications: previous CS, hearth diseases, myoma, elderly patients. We found increase in the indications like: unfavorable pelvic score, atypical or pathological cephalic presentations, ophthalmic diseases, prolonged period of ruptured membranes. The increase of CS rate is mainly due to the relative indication and to the indications based on the subjective assessment of the fetal well-being and of the obstetric status.
