1986～1989本院年间共分娩12489例,其中双胎106例,胎儿总数212例,发生窒息的47例,窒息发生率22.2％,与同期单胎窒息的发生率5.2％相比,P<0.01有高度显著性差异。体重愈低窒息发生率和死亡率愈高。经阴道自然分娩窒息的发生率最低为16.5％,而产钳、臀助臀牵引窒息率高,分别为86.9％及57.6％。双胎一产和二产之间窒息的发生率无明显差异;胎先露双头先露窒息的发生16.4％、死亡率2.9％均较低,臀头先露窒息率37.5％,死亡率18.7％明显高于其他种类先露。作者认为臀头双胎尽应早采用剖宫结束分娩,头臀有条件可酌情经阴道分娩,双头先露若无头盆不称,胎儿体重不过大,特别是第一胎儿已入盆,多数可经阴道分娩。
Between 1986 and 1989, a total of 12489 cases were delivered in this hospital, including 106 cases of twins, 212 cases of fetuses, 47 cases of asphyxia and 22.2% of asphyxia, as compared with 5.2% of singletons There is a highly significant difference. The lower the weight, the higher the incidence and mortality of asphyxia. Transvaginal spontaneous delivery of asphyxia the lowest incidence of 16.5%, and forceps, buttocks hip traction asphyxia, respectively, 86.9% and 57.6%. There was no significant difference in the incidence of asphyxia between twins in one birth and two births. The incidence of asphyxiation in fetuses was 16.4%, the mortality rate was 2.9%, and the astigmatism rate was 37.5% and the mortality rate was 18.7 % Was significantly higher than other types of first exposed. The authors believe that as soon as possible after the end of cesarean section twins with childbirth end of delivery, head and hip conditions may be appropriate to vaginal delivery, double headed if no head basin is not known, the fetal weight is not large, especially the first fetus has been into the basin, Most can be vaginal delivery.
