鉴于困难的中位产钳阴道分娩可致婴儿损伤,故近十年内因头盆不称而行剖宫产率有明显增加。而同期产钳分娩率则下降。本文目的在于评价因头盆不称而行剖宫产的有关因素。作者报导Highland Park医院剖宫产分娩186例,第一组分娩48例(1969～1972年),第二组分娩138例(1979～1982年),两组诊断的头盆不称者均占29%,因头盆不称行剖宫产的百分比第二组为13.1%明显高于第一组5.4%,而第二组产钳分娩率6.3%则明显低于第一组25.6%,第二组婴儿出生体重比第一组平均增加300g,说明头盆不称为第二组剖宫产率增高的原因,但围产期死亡率第二组为7‰分娩,明显低于第一组的14‰。
In view of the difficulties in the midline forceps vaginal delivery can cause infant injury, so the last decade due to cephalopelvic disproportion of cesarean section rate increased significantly. During the same period, forceps delivery rate decreased. The purpose of this article is to evaluate the causal factors of cesarean section due to headache. The authors reported 186 cases of cesarean delivery at Highland Park Hospital, 48 cases (1969-1972) of the first group and 138 cases (1979-1982) of the second group, with 29 %, The percentage of cesarean section due to headache was 13.1% in the second group was significantly higher than 5.4% in the first group, while 6.3% in the second group was significantly lower than the 25.6% in the first group, the second group Infant birth weight than the first group an average increase of 300g, indicating that the first basin is not rated as the second cause of increased cesarean section rate, but the second group of perinatal mortality was 7 ‰ birth, significantly lower than the first group of 14 ‰.
