The evaluation of respiratory distress syndrome (RDS) risk factor evidence in newborns

The aim of this study was to evaluate RDS risk factors in newborns of mothers with define pregnancy complications. The study group included mothers with imminent preterm delivery, intrauterine growth retardation, gestation cholestasis, serological collision, oligo- and polyhydramnios and foetus life threatens risk factors. RDS appeared in newborns born up till 35 weeks of gestation, for the risk factors analysis only preterm delivery, which were ended until 36 weeks of gestation were taken into consideration. Hypertension appeared to be a significant risk factor increasing the risk of RDS evidence 5 times and asphyxia, which increased by 4. In the logistic regression analysis model hypertension showed to increase the risk of RDS evidence 6 times, even when the time of delivery was considered. A, when the time of gestation was prolonged even one week the risk of RDS was decreased by 30%. The was no significant increase in RDS evidence in offspring of mothers with diabetes mellitus, cholestasis gravidarum, hypotrophia foetus or oligo and polyhydramnios.
