[A study of uterine contractility in the onset of labour (author's transl)]

We have studied uterine contractility in 100 inductions of labour at term. We have been able to compare the effects of oxytocic infusions with rupture of the membranes on contractility. Oxytocic infusions and rupture of the membranes seem to have similar effects on the amplitude as well as on the contractile surface and these effects are quantitatively reinforced by one another.
