Abstract
Caesarean sections (C.S.) performed in the County of Kopparberg during 1951–1960 were studied. During this period 41 179 deliveries took place. The C.S. rate was 1.6%. In the Central County Hospital the rate was 2.7% and in the County Hospitals 1.6%. Two maternal deaths occurred (0.3%). The perinatal mortality was 9.0%. In the Central County Hospital 25 of 436 infants were lost and in the County Hospitals 37 of 254. In the latter group the number of stillborn infants was high. In a group of elective C.S. performed at term on healthy mothers only 1 of 163 infants died neonatally.
