In a double-blind study of 60 patients undergoing fibreoptic bronchoscopy we have compared the local anaesthetic effects of intratracheal injections of cocaine (4 ml, 2.5%) and lignocaine (4 ml, 4%). The two local anaesthetics were equally effective in terms of cough suppression, requirement for extra local anaesthetic, patient discomfort and operator acceptability.
在一项针对60例接受纤维支气管镜检查患者的双盲研究中，我们比较了气管内注射可卡因（4毫升，2.5%）和利多卡因（4毫升，4%）的局部麻醉效果。就咳嗽抑制、额外局部麻醉剂的需求、患者不适和操作者接受度而言，这两种局部麻醉剂的效果相当。
