The integrated surface abdominal electromyogram (EMG) has been used as a simple measurement of cough intensity which correlates well with the volume, air flow and noise produced in different coughs. Using the integrated abdominal EMG as a measure of cough intensity, dose response curves to inhaled citric acid can be drawn which are highly reproducible. We have studied the effects of codeine (60 mg) on these curves, and have demonstrated a reduction in cough intensity. It is suggested that this method of testing the effects of an antitussive on such a dose-response curve may be a useful one.
体表腹部肌电图(EMG)已被用作咳嗽强度的一种简单测量方法,它与不同咳嗽产生的音量、气流和噪音密切相关。以体表腹部肌电图作为咳嗽强度的衡量指标,可以绘制出对吸入柠檬酸的剂量反应曲线,这些曲线具有高度可重复性。我们研究了可待因(60毫克)对这些曲线的影响,并证明咳嗽强度有所降低。有人认为,这种测试镇咳药对此类剂量反应曲线影响的方法可能是一种有用的方法。
