Four hundred and thirty-one vacuum extraction deliveries were reviewed during a five-year period from 1978 to 1983. All cases involved the use of the Kobayashi silastic cup vacuum extractor with nine 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. Seventy-five percent of the infants had Apgar scores greater than 7 at one minute, and 97% had scores greater than 7 at five minutes. Fetal morbidity was impressively low, with a cephalohematoma rate of 6% and only two instances of major fetal cranial hemorrhages. In comparison with the reported morbidity sited by other authors using the metal cup extractor, less fetal scalp trauma may be anticipated with the judicious use of the Kobayashi silastic cup vacuum extractor.
对1978年至1983年五年间的431例真空吸引分娩进行了回顾。所有病例均使用小林硅橡胶杯真空吸引器，由9位参与的产科医生进行操作。特别关注与使用硅橡胶杯吸引器相关的母婴发病率。未发生母婴死亡。阴道和宫颈裂伤导致的产妇发病率为4%。75%的婴儿1分钟时阿氏评分大于7分，97%的婴儿5分钟时评分大于7分。胎儿发病率极低，头颅血肿发生率为6%，仅出现两例严重的胎儿颅内出血。与其他作者报道的使用金属杯吸引器的发病率相比，合理使用小林硅橡胶杯真空吸引器可能会减少胎儿头皮创伤。
