[Changes in perinatal mortality in twins].
Perinatal mortality of twins born in South Moravian Region in the years 1983-1987 was compared with that observed in the years 1970-1976. The perinatal mortality of twins decreased from 119,35 per thousand to 64,21 per thousand (the corresponding numbers for the whole population of the region in question are 16.48 per thousand and 11.30 per thousand respectively). The mortality of twins shows no reasonable changes. The early neonatal mortality decreased from 98.32 per thousand to 41.23 per thousand (the corresponding numbers in the whole population are 10.25 per thousand and 6.05 per thousand respectively). As in other countries the most important cause is the decrease of prematurity. This was observed both in the evaluation according to the birth weight and according to the gestational age as well as when the main cause of death was evaluated. Nevertheless also in the second sample a higher mortality of twins B than that of twins A was observed. The results of the leading clinics in the perinatal care show no more higher mortality of twins B namely due to the decrease of the number of RDS deaths. To achieve such object will be the nearest task in our perinatal care for the twins pregnancies and neonates.
