A study was made of the characteristics of oxytocin-induced labour. Twelve patients with, and eight without membrane rupture were closely matched for factors likely to influence the character and duration of labour. In both groups uterine activity increased until a stable state was achieved loowing which there was little alteration until delviery. The duration of labour was shorten in the group with ruptured membranes as compared with intact membranes although, paradoxically, the uterineactivity tended to be greater when the membranes were intact.
对催产素引产的特征进行了一项研究。12例有胎膜破裂的患者和8例无胎膜破裂的患者在可能影响产程特点和持续时间的因素方面进行了密切匹配。两组子宫活动均增强，直至达到稳定状态，此后直至分娩几乎无变化。与胎膜完整组相比，胎膜破裂组的产程缩短，尽管自相矛盾的是，胎膜完整时子宫活动往往更强。
