To evaluate neonatal outcomes following failed vacuum extraction using the Kiwi OmniCup vacuum device.
We conducted a retrospective study of 288 failed vacuum deliveries using the OmniCup device. The neonatal morbidity was recorded for each delivery.
Of the 288 women involved, 82.3% were nulliparous. In 245 cases (85.1%), failed vacuum was followed by successful forceps delivery; failed vacuum and failed forceps was followed by Caesarean section in 5.9%; failed vacuum was followed by spontaneous vaginal delivery in 3.8%; and failed vacuum was followed by Caesarean section in 5.2%. Cephalhematoma was diagnosed in 19.8% of the 288 infants delivered. There were no cases of neonatal intracranial or subgaleal hemorrhage.
Although the method of delivery following failed vacuum extraction is controversial, and most national guidelines warn of increased neonatal morbidity with subsequent use of forceps, the low morbidity in this study is reassuring. In our cohort, low forceps delivery (station > 2 cm) following failed vacuum extraction was not associated with serious neonatal morbidity.
评估使用奇异果全能杯真空吸引装置进行真空吸引失败后的新生儿结局。
我们对288例使用全能杯装置进行真空吸引失败的分娩进行了回顾性研究。记录每次分娩的新生儿发病率。
在参与研究的288名女性中，82.3%为初产妇。在245例（85.1%）中，真空吸引失败后成功进行了产钳助产；5.9%的产妇在真空吸引失败且产钳助产失败后进行了剖宫产；3.8%的产妇在真空吸引失败后自然阴道分娩；5.2%的产妇在真空吸引失败后进行了剖宫产。在288例分娩的婴儿中，19.8%被诊断为头颅血肿。没有新生儿颅内出血或帽状腱膜下出血的病例。
尽管真空吸引失败后的分娩方式存在争议，且大多数国家指南警告后续使用产钳会增加新生儿发病率，但本研究中较低的发病率令人安心。在我们的队列中，真空吸引失败后低位产钳助产（胎头位置>2 cm）与严重新生儿发病率无关。
