title: [Histological changes in the placenta following tokolysis therapy (author's transl)].
abstract: In 138 tokolytically treated cases of imminent abortion or premature birth the secundines were examined histologically and compared with 390 cases of pathological gravidities or births without tokolysis therapy. The frequency of occurrence of morphologically manifested circulatory disturbances following tokolysis therapy was equal to that in the untreated cases, the rate of ascendent infections was only slightly increased. In tokolytically treated placentas with the histological pattern of "dissociated disturbed maturation" and "Maturitias retarda" are prevailing. Thus in most cases sufficient supply of the fetus is possible and the critical phase of uteroplacental insufficiency with the danger of abortion or premature birth may be overcome. There were no hints at direct influences of tokolysis on placental morphology.
