Two techniques for anaesthetising the nose before fibreoptic bronchoscopy have been compared. Fourteen of 16 patients given lignocaine spray found it unpleasant, compared with three of 20 patients given lignocaine gel. The two forms of local anaesthetic were found to be equally effective. Lignocaine gel is therefore recommended for topical nasal anaesthesia before fibreoptic bronchoscopy.
对纤维支气管镜检查前两种麻醉鼻子的技术进行了比较。16例使用利多卡因喷雾的患者中有14例觉得不愉快，相比之下，20例使用利多卡因凝胶的患者中有3例有此感觉。发现两种局部麻醉剂的效果相同。因此，推荐在纤维支气管镜检查前使用利多卡因凝胶进行局部鼻麻醉。
