私達は37例の分娩時に.ストレンゲージの小さな圧力トランスジューサを用いて胎児産道間圧を測定し,これから娩出力を知るexpulsive activityを求めた.Expulsive activityは子宮口開大にともなって増大し,初産婦の子宮口開大7cm以後ならびに破水後には著しく大きくなった.Expulsive activityが200橋本単位以下では子宮口開大度如何にかかわらず,子宮口開大は進行せず,分娩は遷延した.胎児産道間圧は羊水圧と有意の相関があり,expulsive activityは羊水圧から求められるuterine activityと有意の相関が認められた.子宮頚管の深さが異なる3部位で測定されたexpulsive activityの子宮口開大にともなう変動様式は3つに分けられた.子宮頚管の深い部位のexpulsive activityが子宮口開大の進行にともなって常に大きいものをI型とし,それが常に小さいものをII型とした.また,子宮口開大の前半ではI型の特徴をもち,その後半ではII型の特徴をもつものをIII型とした.このように生体力学的特徴から分けられたこれらの3型では,子宮頚管の形態学的,物理学的ならびに物理学的ならびに臨床的にそれぞれ異なった性質を示した.娩出力の子宮口開大作用を知るために,expulsive effort, 効率指数および子宮頚管の抵抗形質などの新しいパラメーターを考案して,微弱陣痛,破水や子宮頚管の未熟性などが分娩時の子宮口開大に及ぼす影響を臨床生理学的に解析した.
