After induction of anaesthesia laryngoscopy was performed and trachea intubated. We recorded: Visualisation of glottis (Cormack Lehane grade), ease of intubation, number of attempts; need to change the blade and need for external laryngeal manipulation.\n <\/jats:p>\n <\/jats:sec>\n \n Statistical Analysis:<\/jats:title>\n \n Demographic data, Mallampati classification were compared using the Chi-square test. A\n P<\/jats:italic>\n <0.05 was considered significant.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Grade 1 view was obtained most often (87% patients) with Trueview\n \u00ae<\/jats:sup>\n laryngoscope. Intubation was easier (Grade 1) with Trueview\n \u00ae<\/jats:sup>\n and McCoy blades (93% each). Seven patients needed two attempts; one patient in Miller group needed three attempts.
