The laryngeal mask airway in resuscitation

Previous work has shown that insertion of the laryngeal mask airway is a skill that is easily taught to inexperienced operators. In this study we have assessed the ability of non-anaesthetists to maintain an airway in a paralysed, anaesthetised patient in the controlled setting of an anaesthetic room. The methods used to maintain the airway included a tightly fitting facemask, using a one-handed and two-handed technique, and a laryngeal mask airway. The inspired volume delivered to the patients was standardised using a Penlon Nuffield ventilator attached to the breathing system. Our results showed no difference in success in maintaining the airway between the three techniques or in the mean expired volumes achieved during successful ventilation.
