Topical anesthesia of the respiratory tract for fibreoptic bronchoscopy was compared, in a single-blind study, inhaled from a simple and inexpensive jet nebuliser, administered by cricothyroid injection or by a 'spray-as-you-go technique'. Each technique was supplemented by spraying lignocaine through the fibrescope and intravenous fentanyl-droperidol sedation. Inhaled nebulisation was successfully used for 96% (46 of 48) of patients, was safe, effective and acceptable to the patient and bronchoscopist. The cricothyroid injection method produced better conditions than nebulisation in patients who had diagnostic bronchoscopy. The nebuliser technique is as satisfactory as the spraying technique in patients for diagnostic bronchial lavage in whom bleeding from a cricothyroid puncture is unacceptable. Patients who used the nebuliser were more satisfied. This technique may also be a useful method for 'awake' intubation.
在一项单盲研究中，对纤维支气管镜检查时呼吸道局部麻醉的三种方法进行了比较，分别是通过简单且廉价的喷射雾化器吸入、环甲膜注射给药以及“边推进边喷雾技术”。每种技术均辅以通过纤维支气管镜喷洒利多卡因以及静脉注射芬太尼-氟哌利多镇静。吸入雾化成功应用于96%（48例中的46例）的患者，对患者和支气管镜检查医师而言是安全、有效且可接受的。对于接受诊断性支气管镜检查的患者，环甲膜注射法产生的条件优于雾化法。在因环甲膜穿刺出血不可接受而进行诊断性支气管肺泡灌洗的患者中，雾化器技术与喷雾技术同样令人满意。使用雾化器的患者满意度更高。该技术也可能是一种有用的“清醒”插管方法。
