Abstract
Methylene blue was placed in the pharynx of 64 patients undergoing anaesthesia with the laryngeal mask. No leak of dye into the larynx was detected on fibreoptic inspection of the inside of the mask in any subject. The use of the laryngeal mask as a means of protecting the airway during procedures such as minor nasal operations is therefore supported.
摘要
将亚甲蓝置于64例使用喉罩进行麻醉的患者咽部。在对任何受试者的喉罩内部进行纤维光学检查时，均未检测到染料漏入喉部。因此，支持在诸如小型鼻腔手术等操作过程中使用喉罩作为保护气道的一种手段。
