Ten percent lignocaine spray is in widespread clinical use as a means of suppressing responses to tracheal intubation. It is sprayed from a multidose container into the glottis and on to the vocal cords through an applicator nozzle, which may be used on successive patients. We have investigated the likelihood of the contamination of these nozzles, with patients' mouth flora. Spray applicators from four of the 20 cases investigated showed contamination with potential bacterial pathogens. We therefore recommend that lignocaine spray should not be applied to successive patients using the same applicator nozzle.
10%的利多卡因喷雾剂作为一种抑制气管插管反应的手段在临床上广泛使用。它从多剂量容器中通过一个涂抹器喷嘴喷入声门和声带，该喷嘴可用于连续的患者。我们调查了这些喷嘴被患者口腔菌群污染的可能性。在调查的20个病例中，有4个病例的喷雾涂抹器显示被潜在的细菌病原体污染。因此，我们建议不应使用同一涂抹器喷嘴为连续的患者应用利多卡因喷雾剂。
