[Dynamic tests of the placental efficiency (author's transl)].

The paper presents a cycle of clinical investigations concerning an early detection of placental insufficiency states. It has been found that in cases of placental changes of a decreased function type, the transport of atropine through the placenta becomes difficult or inhibited, which is manifested by a decrease or lack of a reaction from the fetal side. In cases of the positive test, the fetus responds with tachycardia following atropine administration, which testifies to the normal atropine transport from mother to fetus and to the normal placental function. It has been pointed out that owing to its simple principle, atropine test should find a wide application in obstetric clinic in detecting an early placental insufficiency.
