[Development of perinatal mortality rate in a central hospital (author's transl)].

Perinatal mortality rate is an important parameter of the obstetrical efficacy. The analysis of case reports of 10 590 newborn infants results in the fact, that perinatal mortality could be decreased from 27,15% to 20,11%. Special interest is directed to subpartual mortality, being the proportion of entire mortality reflecting the quality of intrapartal supervision. Critical and precise single case analysis of subpartual deaths was performed in order to detect failures of the supervision system with consequential amelioration of perinatal care. Methods of intensive obstetrical care, introduced since 1973 such as ultrasonic diagnostic, screening for placental insufficiency, amniotic fluid diagnostics tocolysis, cardiotocography and micro-blood analysis, resulted in a significant raise of quality. Unselected perinatal mortality could be decreased by approximately 25%.
