我们近年来对39周以上的外倒转术共做521例,成功率达98.7％,其中只有7例因骨盆狭窄施行倒术无意义,其它顺利的都矫正了.妊娠39周以上施行倒转术的例数如下表: 一,异常胎位外倒转适应症系在胎膜未破,头盆相称者,胎儿能从产道娩出的,为先兆子宫破裂、前置胎盘、胎盘早剥、有刮腹产史者. 二、处理;术前充分准备后在操作中大胆细心取得孕妇合作,手法一定要技巧. (一)臀位外例转术:孕妇排空小便仰卧在床上,屁膝屈髋放松腹壁,术前胎心音每分钟130-150次可施行断续的手法操作,过程中要稳住每一次转动的进展,有官缩时要暂停,在术中要听胎心音的变化,直到矫正胎儿为止. (二)横位外倒转术;方法和臀位一样,不同点就是儿头在左侧就向左转,儿头在右侧就向右转.斜位倒转术,因为胎头在脐的左上方或左下方,有的胎头在右
In recent years, we have done 521 cases of external inversion for more than 39 weeks, with a success rate of 98.7%, of which only 7 cases were unsuccessful due to pelvic stenosis, and others were well corrected. The number of cases in the table below: First, the abnormal fetal position reversal Indications in the fetal membrane is not broken, the first basin is commensurate, the fetus can be delivered from the birth canal, a precursor uterine rupture, placenta previa, placental abruption, history of scraping belly Second, the treatment; fully prepared before surgery in the bold and meticulous cooperation in the operation of pregnant women, techniques must be skillful. (A) breech surgery cases: pregnant women emptied supine on the bed, hip flexor flexor abdominal relaxation, Preoperative fetal heart rate 130-150 beats per minute can be performed intermittent operation, the process should be to stabilize the progress of each rotation, there are official downsizing to be suspended during surgery to listen to changes in fetal heart sound until corrected Fetal so far. (B) transverse lateral inversion surgery; method and the buttocks, the same point is different from the left turn on the left child, the right turn on the right child. Upper left or lower left umbilical, and some fetal head in the right
