It was informed an average percent of success of replacement in the first attempt (55.4%). Conclusions: laryngeal mask was placed successfully in less than twenty seconds, the successes was not related to the classification of Mallampati and positively with the number of cases of the operator and the most frequent problems were the fault by pressing against the palate, the suboptimal position of head and neck and the mask rotated on its axis.
