[Features of uterine contractile function in intrauterine fetal death].
Experiments on 528 pregnant rats studied the specific features of uterine contractility in pre- (7.2%), postimplantation (5.69%), and intrauterine (1.14%) fetal deaths and in ablatio placentae (0.57%) which spontaneously occurred in this group of animals. By applying the multiparametric approach and the methods of the image recognition theory, the authors showed that despite its onset periods, fetal deaths resulted in reduced uterine contractility. It is concluded that the present study provides experimental evidence for the development of weak clinical uterine activity in fetal death in different periods of pregnancy. At the same time, myometrial responses to oxytocin decrease.
