目的观察择期足月剖宫产时机对母婴的影响。方法选取孕37~41+6周,无医学指征、无妊娠及内科合并症,初次行择期剖宫产的宫内单胎孕妇2 176例,其中孕37~38+6周行剖宫产的产妇1 054例作为A组,孕39~41+6周行剖宫产手术的孕妇1 122例作为B组,比较2组母婴不良事件的发生情况。结果 2组孕妇平均住院时间、产后出血发生率、出血量及产褥病率比较差异无统计学意义(P>0.05)。B组新生儿体质量、身长均大于A组新生儿,差异均有统计学意义(P<0.05)。A组新生儿窒息、吸入性肺炎、颅内出血、高胆红素血症等发生率高于B组,差异均有统计学意义(P<0.05)。结论孕39周前行剖宫产,新生儿出现并发症的风险增高,无医学指征的的剖宫产以39周后实施为宜。
Objective To observe the effect of full-term cesarean delivery on maternal and infant. Methods Pregnancy 37 ~ 41 + 6 weeks, no medical indications, no pregnancy and medical complications, the first elective cesarean delivery of intrauterine pregnancies 2 176 cases, of which 37 ~ 38 + 6 weeks of pregnancy cesarean section Of 1 054 pregnant women who underwent cesarean section as group A and 39 to 41 + 6 weeks of pregnancy were enrolled as group B, and the incidence of adverse events in both groups was compared. Results The average length of hospital stay, postpartum hemorrhage, bleeding volume and the rate of puerperal morbidity in the two groups were not significantly different (P> 0.05). The body weight and length of newborns in group B were greater than those in group A, the difference was statistically significant (P <0.05). A group of neonatal asphyxia, aspiration pneumonia, intracranial hemorrhage, hyperbilirubinemia incidence was higher than the B group, the difference was statistically significant (P <0.05). Conclusion Cesarean section was performed 39 weeks before pregnancy. The risk of complications was higher in newborns. Cesarean section without medical indications was implemented after 39 weeks.
