Vacuum Extraction


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.

Priver probably completed residency about the same time I did (1978), when every resident was expected to be proficient in low and mid forceps (and although never sanctioned, some high forceps), Piper forceps, and vacuum extraction. C-sections required a consult from attending staff and were frowned upon when a mid-forcep rotation from OP (occipitoposterior) position to OA (occipitoanterior) position might make an easy delivery But I trained in the military and had a tremendous amount of freedom as well as some super staff teaching me so I was not concerned with the unlikely possibility of a lawsuit.
