The role of amniotomy in active labor is controversial because of contradictory data and a paucity of randomized studies. A randomized trial was conducted on the role of amniotomy in spontaneous labor. Fifty-three women who were admitted to the Family Medicine Service in active labor were randomly assigned to receive amniotomy (n = 26) or no amniotomy (n = 27). Amniotomy shortened the time from randomization to delivery by 143 minutes (t = 2.3, P less than .05, 95% confidence interval [CI] = 19-265). After adjusting for possible confounders, the effect of amniotomy was to shorten labor by 155 minutes (CI = 9-301). The effect of amniotomy on labor was not found to be related to parity or cervical dilatation. Amniotomy had no apparent effect on Apgar scores or use of analgesia.
由于数据相互矛盾且缺乏随机对照研究，人工破膜在活跃期分娩中的作用存在争议。针对人工破膜在自然分娩中的作用开展了一项随机试验。五十三名进入家庭医学科处于活跃期分娩的女性被随机分配接受人工破膜（n = 26）或不接受人工破膜（n = 27）。人工破膜使从随机分组到分娩的时间缩短了143分钟（t = 2.3，P < 0.05，95%置信区间[CI] = 19 - 265）。在对可能的混杂因素进行校正后，人工破膜的效果是使产程缩短155分钟（CI = 9 - 301）。未发现人工破膜对产程的影响与产次或宫颈扩张有关。人工破膜对阿氏评分或镇痛药物的使用没有明显影响。
