Intravenous dexmedetomidine vs. lignocaine in attenuating the hemodynamic responses during laryngoscopy and endotracheal intubation: a randomized double blind study

ABSTRACT

Background: The stress response to laryngoscopy and endotracheal intubation is a commonly encountered physiological phenomenon. Though the response can be transient and harmless in normotensive healthy patients, but it may prove hazardous amongst patient with underlying cardiac disease, or hypertensive disease and its sequelae. Present study was planned to evaluate the efficacy of IV dexmedetomidine infusion and IV lignocaine in attenuating the hemodynamic responses during laryngoscopy and intubation
