Neonatal asphyxia causes hypoxic-ischemic encephalopathy and may damage the central nervous system. We studied neonatal asphyxia with photo-evoked eyelid microvibration (PEMV) which is a blink reflex elicited by photic stimuli. The latency of PEMV changed according to the severity of encephalopathy and the degree of unconsciousness. All of the neonate who had showed disappearance of PEMV died. When the prolonged latency persisted, the infant had a strong probability of sustaining neurological sequelae. PEMV provides useful information for predicting the outcome of neonatal asphyxia.
新生儿窒息会导致缺氧缺血性脑病，并可能损害中枢神经系统。我们利用光诱发眼睑微振动（PEMV）对新生儿窒息进行了研究，PEMV是一种由光刺激引发的眨眼反射。PEMV的潜伏期会根据脑病的严重程度和意识丧失程度而变化。所有出现PEMV消失的新生儿均死亡。当潜伏期持续延长时，婴儿发生神经后遗症的可能性很大。PEMV为预测新生儿窒息的预后提供了有用信息。
