THE ROLE OF LARYNGEAL MASK AIRWAY IN CARDIOPULMONARY-RESUSCITATION

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.
