The incidence of pharyngolaryngeal adverse events associated with laryngeal mask airways can be reduced by the use of manometry to limit the laryngeal mask airway intracuff pressures. We conducted a prospective, observational study in 80 patients undergoing general anaesthesia with the ProSeal™ laryngeal mask airway to determine the accuracy of a finger palpation technique compared to actual readings obtained from a hand-held manometer by different anaesthesia personnel. The strength of association of estimated versus actual intracuff pressures, R, for nurse anaesthesia assistants, junior anaesthetists and senior anaesthetists were 0.21 (weak), 0.35 (moderate) and 0.78 (strong) respectively. Subgroup analysis showed that anaesthetists with more than three years of experience were more accurate than those with less than three years of experience. The actual versus estimated intracuff pressures were 4±17 vs 19±27 cmH2O (P value <0.001) respectively. In all groups, the palpation technique tended to underestimate the actual intracuff pressure by a mean of 10.3 cmH2O. Palpation accuracy decreased when actual intracuff pressures were >80 cmH2O. These findings suggest that cuff pressure manometry should be recommended as standard of care with the use of laryngeal mask airways.
