根据日本东北大学医学院附属医院1973～1977年的资料统计,臀位分娩占总分娩的4.7%,据作者统计约占3～6%.臀位分娩与头位分娩相比,臀位分娩造成难产的较多,对胎儿的影响较大.臀位经阴道分娩时,其圃产期死亡率和新生儿患病率要比头位分娩高2～10倍,主要原因为:(1)早产儿多;(2)先天性异常发生率高;(3)容易产生胎儿低氧症;(4)分娩损伤多.(1)、(3)、(4)与臀位分娩很有关系,臀位分娩与头位分娩本质上的区别是最大部位的头部娩出最迟会压迫脐带,影响分娩,容易造成脐带脱垂.此外,臀位分娩还易引起早期破水诱发早产,而增加了围产期早产儿特有的危险性.
According to statistics of Affiliated Hospital of Northeastern University School of Medicine from 1973 to 1977, breech delivery accounted for 4.7% of the total delivery, according to the author’s statistics about 3 to 6% .Birth breech delivery compared with the first delivery, breech delivery caused The more dystocia, the greater impact on the fetus breech vaginal delivery, its nursery birth rate and neonatal morbidity than the head delivery 2 to 10 times higher, mainly due to: (1) premature birth (2) high incidence of congenital abnormalities; (3) prone to fetal hypoxia; (4) more labor injury (1), (3), (4) and breech birth are closely related, hip The difference between the first delivery and the first delivery is the head of the largest part of the delivery of the umbilical cord at the latest will affect the delivery, likely to cause umbilical cord prolapse.In addition, breech delivery is also easy to cause early broken water-induced premature delivery, and increased perinatal Period of preterm children unique risk.
