The authors discuss the care of an insulin-dependent diabetic woman during delivery. Due to the introduction of modern procedures in diabetology, obstetrics and neonatology the perinatal mortality in diabetic pregnancies is close to that in healthy women. In the Zlín region there was in 1997 a total of 2301 deliveries, incl. 8 IDDM patients (0.34%) and 32 patients with gestational diabetes (0.72%). The perinatal mortality in diabetic pregnancies was 0 pro mille and in non-diabetic ones 5.14 pro mille.
