Abstract
Objective To study the causes of fetal distress after active labor phase of full-term pregnancy and the perinatal outcomes of different delivery modes.Methods The fetal data within 2 years in Nuclear Industry 215 Hospital in Shaanxi Province were analyzed retrospectively, and the cases of fetal distress were analyzed.The cases were divided into cesarean section group and vaginal delivery group based on final delivery modes.Risk factors of fetal distress were analyzed and the incidence of fetal complications was compared in different delivery modes.Results Among 4928 cases, 278 cases (5.64%) of fetal distress occurred, among which 162 cases (58.27%) were taken by cesarean section and 116 cases (41.73%) were taken by vaginal delivery.The mother, fetus, placenta, umbilical cord, amniotic fluid and labor stage were the risk factors of fetal distress.Most fetal distress occurred in the first stage with incidence of 80.9%, which was higher than that of the second stage of labor (19.1%).Diabetes abnormalities could lead to the increase of fetal distress occurrence in acceleration and deceleration phase (χ2 value was 14.057 and 57.140 respectively, both P<0.001).Premature rupture of water increased labor fetal distress rate in the deceleration stage and the second stage (χ2 value was 16.444 and 11.735, respectively, both P<0.01). Abnormal birth process could cause maximum increase of fetal distress in acceleration, deceleration stage and the second stage (χ2 value was 7.610, 26.135 and 13.318, respectively, all P<0.001).Neonatal complication rate in cesarean section group was significantly lower than that in vaginal delivery group (χ2 =8.603, P=0.003).Conclusion For fetal distress after active period in primipara with full-term pregnancy, different delivery modes can help to achieve good perinatal outcomes.The key factors for reducing perinatal morbidity and mortality are early diagnosis, correct treatment and choosing of proper delivery mode based on labor stage and fetal hypoxia degree.关键词
