两个有严重窒息史的新生儿,有明显脑干功能障碍,除第八对颅神经外,脑干听力反应均未测到。两例治愈后,脑干反应亦恢复。所以,脑干功能障碍伴腑干听力丧失,对新生儿来说是可逆的。脑干听力反应,是脑部受到刺激所引起的电位记录,提供脑组织功能完善程度的客观指标。方法:用声系到刺激耳蜗,通过听觉产生微小电压。然后用计算机求平均数的方法对微小电压分离、放大。仪器:用记录运电场的氯化银圆盘电极,置于前囟部和双乳突部,通过耳机给予短暂音响刺激,周期
Two newborns with a history of severe asphyxia had obvious brainstem dysfunction. Except for the eighth cranial nerve, the brainstem response was not detected. After two cases of cure, brainstem response also recovered. Therefore, brainstem dysfunction associated with loss of dry hearing, is neonatal reversible. Brainstem auditory response, is caused by stimulation of the brain potential record, to provide objective indicators of the degree of functional improvement of brain tissue. Methods: Sonic stimulation of the cochlea to produce a small voltage through hearing. And then use the computer method of averaging small voltage separation, amplification. Apparatus: A silver chloride disk electrode for recording the electric field is placed in the anterior fontanelle and the dura mastoder, giving a brief acoustic stimulus through the earphone, the period
