【摘要】 为了观察豚鼠在麻醉和清醒状态的畸变产物耳声发射 (DPOAE)。我们以 DPOAE幅值和 I/ O曲线作为参数 ,观察清醒和麻醉状态下其参数的变化。结果发现豚鼠在清醒状态下其 DPOAE幅值和 I/ O曲线斜率与正常剂量麻醉状态下相比无显著性差异 (P>0 .0 5 )。我们认为在清醒状态下豚鼠 DPOAE的检测同麻醉状态相比 ,操作简便、结果稳定 ,更接近于生理状态。更多还原

【Abstract】 In order to observe the DPOAE of guinea pigs under awake and anesthetic conditions,we invesitigated the amplitude of distortion product emission and I/O function curves and made a comparative analysis of their changes under different conditions. It was found that the amplitude of DPOAE and I/O curves did not show difference in the guinea pigs under awake and anesthetics conditions.We deem it credible and simple to measure DPOAE in the guinea pigs under awake condition,which is similar to measuring DPOAE in the guinea pigs under physiological condition.更多还原
