[Effect of methylergometrin on involution of the uterus in the early puerperium].

The effect of a routinely administered uterotonic medication is examined prospectively in a group of 69 puerperal women, which is matched with an untreated group of 71. The sonographically measured involution of the length of the uterus and the puerperal morbidity are compared and no difference is found between the two groups.
