The uterine contractions were recorded before, at, and after spontaneous timely rupture of the membranes. The peculiarities of the rupturing contraction were studied and were compared with the prerupture pattern of uterine contractility. It was observed that the rupturing contraction was not the strongest one to which the membranes were subjected in 86.2 per cent of cases. To solve this topographic phenomenon, a new test, “the repeated stretching test,” was instituted. A new conception was then introduced to explain how timely rupture of the membranes takes place. During labor, nature utilizes uterine contractions to influence a repeated stretching action upon the membranes. This progressively and gradually weakens the membranes until, by the end of the first stage, their resistance is reduced to a degree that allows weaker uterine contractions to effect their rupture. |
