The laryngeal mask airway (LMA) has been newly introduced to anaesthesia practice as an alternative to the endotracheal tube (ETT) or face mask for airway management. It is capable of providing a rapid and easily achieved patent airway that permits positive pressure ventilation within confined limits. In this study, we aim to evaluate the role of the LMA in cardiopulmonary resuscitation (CPR) in 20 patients as an alternative to tracheal intubation. Study parameters included measurement of oxygen saturation by a pulse oximeter and end-tidal carbon dioxide level (ETCO2) using the Fenem CO2 analyser. Five of these 20 cases were resuscitated using endotracheal tubes as a control group. Seven cases were resuscitated using LMA only and eight cases were resuscitated using LMA initially followed by ETT for long term ventilation. In the LMA groups I and III, 12 patients had LMA inserted at the first attempt and three at a second attempt. We concluded that LMA is a good alternative to ETT, although it may not protect against aspiration. We recommend it to be included in CPR chart cards and all medical doctors, nurses and paramedical staff should learn how to use it.
喉罩气道（LMA）作为气管内插管（ETT）或面罩用于气道管理的替代方法，已新引入麻醉实践中。它能够提供一个快速且易于建立的通畅气道，允许在一定范围内进行正压通气。在本研究中，我们旨在评估LMA在20例患者心肺复苏（CPR）中作为气管插管替代方法的作用。研究参数包括使用脉搏血氧仪测量氧饱和度以及使用费内姆二氧化碳分析仪测量呼气末二氧化碳水平（ETCO2）。这20例病例中有5例使用气管内插管进行复苏作为对照组。7例仅使用LMA进行复苏，8例最初使用LMA进行复苏，随后使用ETT进行长期通气。在LMA组I和III中，12例患者首次尝试插入LMA成功，3例第二次尝试成功。我们得出结论，LMA是ETT的良好替代方法，尽管它可能无法防止误吸。我们建议将其纳入CPR图表卡，并且所有医生、护士和医护辅助人员都应学习如何使用它。
