[Study on related factors of premature delivery and perinatal management].

OBJECTIVE: To study the etiological factors, perinatal management of premature delivery and the outcome of the premature infants. METHODS: The medical records of normal deliveries over the past 8 years in our hospital were respectively reviewed to analyze the difference between full-term and premature delivery cases in terms of maternal age, perinatal factors and manner of delivery. The states of birthing and outcomes of premature were reviewed. RESULTS: Preterm premature rupture of the membranes and in vitro fertilization-embryo transfer (IVF-ET) were the major causes of premature delivery, which was also related to such factors as placenta previa and pregnancy-induced hypertension. Premature delivery with unknown causes had been decreasing over these years. The maternal age and history of previous birth did not vary significantly between the full-term and the premature groups, but the later had significantly higher rates of cesarean section, in which 67.64% of the cases had Apgar scores
