Comparative Study of the Effects of Gabapentin and Esmolol on Hemodynamic Response to Laryngoscopy and Intubation

The suppression of neurovegetative response to laryngoscopy and intubation has been tried out using several pharmacological agents, such as opioids, local anaesthetics, β-blockers and α2 agonists. Gabapentin an anticonvulsant, while esmolol is a cardioselective β1 blocker and a class II antiarrhythmic, they have shown to attenuate pressor response to direct laryngoscopy and tracheal intubation individually. Given these variable characteristics of two drugs, the present study, a prospective randomized double blind aimed to compare their efficacy against haemodynamic response during intubation and laryngoscopy.
