侧俯卧位预防持续性枕后及枕横位的临床观察

Clinical Observation of Lateral prostrate Position Preventing Persistent OP/OT Position

为探讨同侧侧俯卧位预防持续性枕后及枕横位的临床效果 ,于 1999年 2月至 2 0 0 0年 4月 ,将先兆临产至潜伏期经 B超诊断为枕后位、枕横位的 2 16例产妇随机分为两组。观察组 10 8例产妇采取同侧侧俯卧位 ,对照组10 8例按常规产科护理 ,不作体位指导。结果观察组 82例 ( 75 .93% )胎方位转位成功 ,顺产率 72 .2 2 % ,难产率2 7.78% ,总产程时间平均 5 2 9min。对照组 44例 ( 40 .74% )转位成功 ,顺产率 33.33% ,难产率 6 6 .6 7% ,总产程平均时间 70 7min。两组比较 ,差异有极显著性意义 (均 P<0 .0 0 5 )。提示在产程中实行同侧侧俯卧位是预防持续性枕后位及枕横位。

In order to observe the efficacy of lateral prostrate position, the same side with fetal position to prevent persistent OP/OT position, from Feb. 1999 to April 2000, 108 lying in women with OP/OT position from threatened labor to latent phase diagnosed by ultrasound in our hospital were treated with lateral prostrate position the same side with fetal position as observation group and 108 cases received routine nursing care as control group. The position of the 82 fetuses (75 93%) in the observation group was corrected successfully with the normal delivery rate, dystocia rate and the average time of total stage of labor being 72 22%, 27 78% and 529 min, respectively. Forty four cases (40 74%) in the control group rotated to OA position naturally with the normal delivery rate, dystocia rate and the average time of total stage of labor being 33 33%, 66 67% and 707 min, respectively. There were significant differences betwee the two groups ( P <0 005). It was suggested that the lateral prostrate position the same side with fetal position to prevent persistent OP/OT is an effective method to lower dystocia rate during labors.
