目前连续脑电图监测仍是估计暴发性肝衰竭预后的最可靠的方法,但需专人负责和一定设备。本文报告一种简单易行的,与脑电图变化有同样预后意义的床边试验——前庭眼反射。对30例暴发性肝衰竭,入院时有4级脑病体征的患者进行研究。压迫远端指间关节引起的运动作为痛反应。用瞳孔对光反射、头眼反射和前庭眼反射(OVR)来估计脑干的功能。头眼反射的测定是,使头部在垂直面和水平面来回迅速运动。用20毫升冰水刺激外耳道和鼓膜来检查前庭眼反射。
Continuous EEG monitoring is still the most reliable method of estimating the prognosis of fulminant hepatic failure, but it requires special attention and certain equipment. This article reports a simple, bedside test with the same prognostic significance as EEG changes - vestibular reflexes. Thirty patients with fulminant hepatic failure who had signs of grade 4 encephalopathy on admission were studied. Oppression of distal interphalangeal joint-induced movement as a pain response. The function of the brainstem is estimated with pupil light reflex, head reflex, and vestibular reflex (OVR). Head reflection is measured, the head in the vertical and horizontal plane back and forth rapid movement. Examine the vestibular reflex with 20 ml of ice water to stimulate the external auditory canal and tympanic membrane.
