双胎妊娠44例临床分析

Clinical analysis of 44 twin pregnancies

本文对我院1990～1995年间44例双胎妊娠的分娩方式进行了分析。指出双胎妊娠由于胎位异常、产力异常及妊娠并发症多等因素,难产及手术产率均较单胎明显增高。在25例经阴道分娩的双胎中,阴道手术产率为64％,本组双胎剖宫产率为43.22％。本文认为双胎妊娠的分娩方式应掌握以下原则:当第一胎儿为臀泣、第二胎位为头位,尤其是胎儿较大、羊水较少时,应考虑剖宫产。而单纯的第二胎儿臀位可以经阴道分娩,不必常规剖宫产。

We investigated the delivery manner of 44 twin pregnancies between 1990 and 1995. The result showed that dystocia and operative delivery for twin pregnancy occur more often apparently than mono-cyesis because of the abnormal fetal position, the abnormality of force of labor and pregnancy complication. The rate of operative delivery was 64% in 25 twin pregnancies through vagina. The rate of cesarean section was 43. 2% of this group (44 cases). We regarded that delivery manner of twin should be mastered as follows: when the first fetus was in the position of breech presentation, the second of head presentation. cesarean section should be considered of the bigger fetus and the less amniotic fluid. The vaginal delivery would make it and the cesarean section needn't routine when the second fetus was as breech presentation.
