头位分娩中改变产妇体位对产程的影响

目的:探讨头位分娩中改变产妇体位以矫正胎方位的临床效果。方法:选择先兆临产至潜伏期经B超检查判断为枕后位的初产妇300例,随机分为两组,每组150例。研究组在产程中指导产妇取同侧俯卧位,使胎头在下降时逐渐从枕后位转至枕前位娩出,并与对照组比较。结果:研究组126例(84.00%)经阴道娩出,剖宫产24例(16.00%);对照组经阴道娩出仅44例(29.33%),剖宫产106例(70.67%)。两组比较,差异有显著性(P<0.01)。研究组第一产程平均时间为6.8±1.6小时,第二产程平均为0.8±0.6小时。对照组第一产程平均为11.5±2.30小时,第二产程平均为1.4±0.13小时。两组比较,差异有显著性(P<0.01)。结论:在头位分娩中指导产妇取同侧俯卧位有利于矫正枕后位,降低难产发生。

Abstract Objective ：To investigate the clinical effect on correction of fetal position by changing maternal posture during head de- livery. Methods：the birth to choose aura incubation period B ultrasonic examination after a judge pillow included 300 cases were randomly divided into two groups, each 150 cases. The team in guiding mothers take premature with side prone position Make fetal head drop in gradually transferred to a pillow from a pillow before childbirth, and compared with controls. Results：the team 126 eases（ 84.00% ） transvaginal childbirth goes out, and cesarean section 24 cases （ 16. 00% ） ; The control group transvaginal childbirth goes out just 44 cases （29. 33% ）,and cesarean section 106 cases （70.67%）. Two groups of comparisons, significantly different （ P 〈 0. 01 ）. The team first prolonged duration of 6. 8 ± 1.6 hours on average, the second chosen an average of 0. 8 ± 0. 6 hours. The control group first chosen an average of 11.5 ± 2. 3 hours, the second chosen an average of 1.4 ±0. 13 hours. Two groups of comparisons, differences have significantly（ P 〈 0. 01 ）. Conclusion ： in the delivery head of maternal take ipsilateral prone position for correction of occiput posterior position ,reduce dystocia occurs.
