Abstract
Objective To analyze the effect of vaginal delivery and cesarean section on twin pregnancy outcomes and pregnancy associated risk factors.Methods Clinical data of 86 parturients with twin pregnancy was retrospectively analyzed,and according to different methods of delivery they were divided into research group and control group.Fifty-four cases in the research group were treated with lower segment cesarean section,while 32 cases in the control group underwent vaginal delivery.Incidence of complication in twin pregnancy women was analyzed.At the same time,incidence of postpartum hemorrhage,gestational age, neonatal mortality and asphyxia rate in two groups were compared,and results were statistically analyzed.Results Preterm birth was the complication with highest incidence in twin pregnancy women(38.37%),followed by preeclampsia-eclampsia(16.28%), and incidence of umbilical cord prolapse was lowest(1.16%).Neonatal asphyxia rate and mortality rate at 31-33+6 weeks of pregnancy were highest,followed by ≥37 weeks and 34-36+6 weeks,and differences were statistically significant(χ2 value was 11.04 and 15.47,respectively,both P<0.01).Among newborns in two groups,neonatal asphyxia rate in the second fetus in the control group was significantly higher than that in the first fetus in same group and the second fetus in the research group(χ2 value was 5.38 and 6.72,respectively,both P<0.05),and number of neonates with weight ≥2.5Kg in the research group was notably higher than that in the control group with significant difference(χ2=4.34,P<0.05).Conclusion Preterm birth is major risk factor for twin pregnancy.Lower uterine segment cesarean section can significantly reduce asphyxia rate in twin neonates,and improve maternal and neonatal outcomes in twin pregnancies,so it is worthy of further clinical popularization.关键词
