我们在一项随机研究中比较了31名未预先用药的志愿者进行纤维气道内窥镜检查的四种局部麻醉方法，每个人都作为自己的对照。将木质素喷雾剂、EMLA乳膏、浸泡在4%木质素溶液中的三个棉签或2%木质素凝胶应用于一个小瓶中3分钟。木质素喷雾剂的应用被评为最令人不快的，EMLA乳膏最不令人不快。喷雾和凝胶导致动脉压升高。通过将支气管镜穿过鼻子到口咽部来测试粘膜麻醉，使用木质素喷雾剂或凝胶剂最好。凝胶或EMLA，但不是用棉签涂抹的局部麻醉剂，使视力模糊。当轻微的视力模糊不是问题时，建议使用局部麻醉凝胶麻醉鼻粘膜。对于这里描述的所有方法，建议使用术前用药或镇静。
We have compared four methods of topical anaesthesia of the nostril for fibreoptic airway endoscopy in a randomized study with 31 unpremedicated volunteers, each serving as his or her own control. Lignocaine spray, EMLA cream, three cotton swabs soaked in 4% lignocaine solution, or 2% lignocaine gel was applied in a nostril for 3 min. Application of lignocaine spray was rated as the most unpleasant and EMLA cream the least unpleasant. Spray and gel caused an increase in arterial pressure. Anaesthesia of the mucosa, tested by passing a bronchoscope through the nose to the oropharynx was best with lignocaine spray or gel. Gel or EMLA, but not the local anaesthetic applied with swabs, obscured vision. When slight obscurity of vision is not a problem, local anaesthetic gel is recommended for anaesthesia of the nasal mucosa. Premedication or sedation is recommended for all the methods described here.
