目的探讨体外受精-胚胎移植妊娠双胎分娩时机及分娩方式。方法对175例<34周和≥34周阴道分娩和剖宫产分娩的产妇产后出血量,新生儿窒息情况和新生儿体重进行回顾性分析。结果阴道分娩<34周新生儿窒息和低体重儿的发生与≥34周比较差异有统计学意义;≥34周阴道分娩与剖宫产分娩比较产后出血发生差异无统计学意义;≥34周阴道分娩第一胎儿发生新生儿窒息与剖宫产分娩差异无统计学意义;阴道分娩第二胎儿发生新生儿窒息与剖宫产分娩差异有统计学意义;≥34周胎位为头/头位,阴道分娩和剖宫产分娩第二胎儿发生新生儿窒息差异无统计学意义;胎位为头/非头位,阴道分娩和剖宫产分娩第二胎儿发生新生儿窒息差异有统计学意义。结论在积极预防剖宫产产后出血条件下,应适当扩大双卵双胎妊娠剖宫产适应证。
Objective To investigate the timing of twin birth and delivery mode in IVF-ET. Methods A retrospective analysis was performed on the amount of postpartum hemorrhage, neonatal asphyxia and newborn weight in 175 women <34 weeks and ≥34 weeks of vaginal delivery and cesarean delivery. Results The incidence of neonatal asphyxia and low birth weight infants <34 weeks after vaginal delivery was significantly different from that of ≥34 weeks. There was no significant difference in the incidence of postpartum hemorrhage between vaginal delivery and cesarean delivery more than 34 weeks. No significant difference was found in neonatal asphyxia and cesarean delivery between the first fetus and childbirth; the difference between neonatal asphyxia and cesarean delivery in the second fetus with vaginal delivery was statistically significant; the median vaginal There was no significant difference in neonatal asphyxia between childbirth and cesarean delivery of the second fetus; the fetal head was non-head / non-head, vaginal delivery and cesarean delivery of the second fetus with neonatal asphyxia had statistical significance. Conclusion In the active prevention of bleeding after cesarean section, should be appropriate to expand twin pregnancy twin pregnancy cesarean indications.
