The Investigation of the Relationship between the Mode of Delivery and Pregnancy Outcome in 286 Cases

Objective To analyze and evaluate the relationship between the mode of delivery and pregnancy outcome in twin pregnancy.Methods In the First People's Hospital of Hanchuan City from December 2007 to December 2012,286 cases of twin pregnancy women were divided into groups vaginal delivery group(147 cases) and Cesarean section group(139 cases),and the maternal gestational weeks,postpartum bleeding,neonatal birth weight,Apgar score and neonatal asphyxia rate of the two groups were analyzed.Results postpartum hemorrhage rate difference of different modes of delivery was not statistically significant(P 0.05);newborn weight 2500 g of the virginal delivery group were significantly higher than Cesarean section group(P 0.05);newborn children weighing more than 2500 g with ≥37 weeks of gestation of Cesarean section group were significantly higher than vaginal birth group,the difference was significant(both P 0.05).Differnce of second fetal asphyxia rate between the two groups was statistically significant(P 0.05),and the second fetal asphyxia rate of Apgar score 7 point in the vaginal delivery group was significantly lower than the first fetus(χ2 = 5.117,P 0.05),asphyxia rate of Apgar score ≤7 was significantly higher than the first fetus(χ2 = 4.312,P 0.05).Conclusion Rate of neonatal asphyxia of Cesarean section is independent from the birth order,and choosing the appropriate mode of delivery for twin pregnancy can reduce the rate of neonatal asphyxia.
