Supraglottic devices are frequently used for approach of difficult airway, and situations where it isn't necessary insertion of endotracheal tube. Objective: To identify behavior of some parameters of intraoperative monitoring using three supraglottic devices. Methods: We made a descriptive and observational study in 45 ASA I and II patients, who received general anesthesia for short term surgical procedures. Three groups were divided in a randomized way, with 15 patients in each. In the first one, we used the classic laryngeal mask, in the second one, the Combitube, and in the third one, the COPA cannula. Variables used included: insertion time, systolic and diastolic arterial pressure, heart rate, and oxygen partial saturation before and after placement and peak inspiratory pressure in airway, after insertion. Results: Three devices were easily placed in less than a minute. In arterial pressures and heart rate there weren't significant changes. Oxygen partial saturation was between 95 and 100%. In most of patients, peak inspiratory pressure was above of 25 cm of H2O in all patients in which we used Combitube. Conclusions: Three devices used are a good choice to guarantee a proper oxygenation and ventilation.
