[Cardio-circulatory response to laryngoscopy. Comparative study between Macintosh and McCoy laryngoscopes].
To assess the cardiocirculatory repercussions of laryngoscopy performed with the Macintosh or McCoy laryngoscopes, we studied 20 patients randomly divided into 2 groups of 10 to undergo laryngoscopy with one or the other of the aforementioned instruments. All patients were in good health overall (ASA I or II) and presented no criteria for difficult intubation (Mallampati I or II, distance between the thyroid and the menton greater than 7 cm and maximum distance between the incisors greater than 3.5 cm). The McCoy laryngoscope was associated with significantly lower systolic arterial pressure and heart rate.
