  Review

  Comparative analysis of efficacy of lignocaine 1.5 mg/kg and two different doses of dexmedetomidine (0.5 μg/kg and 1 μg/kg) in attenuating the hemodynamic pressure response to laryngoscopy and intubation.

  Laryngoscopy and intubation cause an intense reflex increase in heart rate, blood pressure, due to an increased sympathoadrenal pressor response. Lignoocaine has shown blunting of pressor response to intubation. Dexmedetomidine has sympatholytic effects. ⋯ We conclude that dexmedetomidine 1μg/kg adequately attenuates the hemodynamic response to laryngoscopy and endotracheal intubation when compared with dexmedetomidine 0.5μg/kg and lignocaine 1.5mg/kg.
