观察静注速尿降低蝎内电位（EP）对声创伤的影响，以静住生理盐水为对照组。二组均暴露在110～130dBSPL的2kHZ纯音5分钟。比较暴露前与暴露后2小时的CAP输入一输出曲线。在125和130dBSPL，H组无差异。在115和120dBSPL速尿组阈移明显大于盐水组。在110dBSPL速泵和生理盐水组无明
To observe the effect of intravenous furosemide on the reduction of internal scorpion potential (EP) on acoustic trauma, and static saline as the control group. Both groups were exposed to 2kHZ pure tone at 110 ~ 130dBSPL for 5 minutes. A comparison of pre-exposure and post-exposure 2-hour CAP input-output curves was performed. At 125 and 130 dB SPL, there was no difference in H group. Threshold shifts were significantly greater in the velcro group at 115 and 120 dB SPL than in the saline group. In the 110dBSPL speed pump and saline group no obvious
