GONZALEZ PEREIRA, Susana et al. Effectiveness of the lidocaine for control of the reflex response during laryngoscopy and endotracheal intubation. MEDISAN [online]. 2011, vol.15, n.10, pp.1369-1375. ISSN 1029-3019.

A cross-sectional study of pharmacological intervention was carried out in order to evaluate the effectiveness of the lidocaine for control of the reflex response associated with the laryngoscopy and endotracheal intubation in a sample of 100 patients operated under general anesthesia in "Dr. Ambrosio Grillo Portuondo" Teaching Clinical and Surgical Hospital in Santiago de Cuba from July 2010 to May 2011, prior to which they were assigned to groups 1 and 2 with 50 patients each: the former were administered a lidocaine bolus (1,5 mg/kg) 2 minutes before beginning the laryngoscopy, but the latter were not. While the results of blood pressure control during the examination of the larynx and endotracheal intubation were better when using this anesthetic, whereas the elevated heart rate and abnormal electrocardiographic images were more common in whom this drug was not used.

Palabras clave : lidocaine; laryngoscopy; endotracheal intubation; heart rate; electrocardiographic image; surgery.
