an obstetrical operation for extraction of the fetus with a special apparatus—the vacuum extractor.
Vacuum extraction entered obstetrical practice after construction of apparatus by V. Finderle (1952, Yugoslavia) and T. Malmström (1954, Sweden). In the USSR original vacuum extractors were proposed by K. V. Chachava and P. D. Vashakidze (1957) and A. I. Petchenko and I. P. Demichev (1957). The vacuum extractor consists of a set of small metallic cups (or a rubber cap) of varying sizes joined by a rubber tube to a vacuum apparatus. Removal of the fetus by vacuum extraction is achieved by the exhaustion of air (vacuum), which is done with a special syringe or electrosuction. Vacuum extraction is used when there is weak labor that threatens intrauterine asphyxiation of the fetus and in other cases. Vacuum extractors are also used to stimulate labor.
