Abstract
Vacuum extraction deliveries (431) [in humans] were reviewed during a 5-yr period from 1978 to 1983. All cases involved the use of the Kobayashi silastic cup vacuum extractor with 9 participating obstetricians performing the procedures. Specific attention was directed toward maternal and fetal morbidity associated with the use of the silastic cup extractor. No maternal or fetal deaths occurred. Vaginal and cervical lacerations accounted for a 4% maternal morbidity rate. Of the infants, 75% had Apgar scores > 7 at 5 min. Fetal morbidity was impressively low, with a cephalohematoma rate of 6% and only 2 instances of major fetal cranial hemorrhages. In comparison with the reported morbidity sited by others using the metal cup extractor, less fetal scalp trauma may be anticipated with the judicious use of the Kobayashi silastic cup vacuum extractor.
