Laryngoscopy and tracheal intubation produce marked sympathetic responses in susceptible-patients. β-blockers counteract these sympathetic activations. Hence, our study was designed to evaluate and compare esmolol as intravenous bolus to a placebo in attenuating sympathetic responses at laryngoscopy and intubation in healthy adults.

Hence, our study was designed to evaluate and compare esmolol as intravenous bolus to a placebo in attenuating sympathetic responses at laryngoscopy and intubation in healthy adults.
