[Rate of cesarean section and perinatal infant mortality at "Maichin dom"].

The aim of this retrospective study is to find the CS rate, which to maintain the perinatal mortality at a lowest possible level in groups of patients with normal and high risk pregnancies. There were 123598 births for a period from 1976 to 2000 years. The CS rate has increased from 4.8% to 24.5% and the PNM has decreased from 27.7@1000 to 11.4@1000. The statistical analysis shows that the for this period the CS rate is one of the factors to decrease the PNM (r = -0.776, p < 0.05). In the group of pregnancies with normal risk the PMN is between 8 and 11@1000 at the CS rate of 15-16% while in the group with high-risk pregnancies the same PNM is achieved with 24-26% CS rate. The antenatal mortality is not influenced by the CS rate and is almost unchanged for 24 years (r = -0.339, p > 0.05).
