Airway management is a critical skill for anesthesiologists, particularly during laryngoscopy and endotracheal intubation, which often trigger a cardiovascular stress response. This response, characterized by transient hypertension, tachycardia, and elevated serum catecholamines, can result in serious cardiovascular complications, especially in high-risk patients. Effective management of this pressor response is therefore essential to ensure patient safety and optimize outcomes during surgery.

Esmolol, a cardio-selective beta-blocker with a short half-life, has been widely studied for its ability to attenuate the pressor response and maintain hemodynamic stability. Conversely, Ivabradine, a selective inhibitor of the "If" current in the sinoatrial node, offers a unique mechanism of reducing heart rate without affecting myocardial contractility or blood pressure. Unlike beta-blockers, Ivabradine is suitable for use in patients with contraindications to beta-blockers, such as those with bronchial asthma, diabetes, or normotensive conditions.

While studies have established the individual efficacy of Esmolol and Ivabradine in blunting the cardiovascular stress response to intubation, no direct comparative study has been conducted to evaluate their relative effectiveness. This randomized controlled trial aims to bridge this gap by comparing oral Ivabradine and intravenous Esmolol in attenuating hemodynamic responses to laryngoscopy and intubation in ASA Grade I patients undergoing elective surgeries. The findings will provide evidence-based insights into optimal pharmacological interventions to minimize perioperative cardiovascular risks and refine anesthetic protocols.

 RELEVANCE OF RESEARCH PROPOSAL TO PUBLIC HEALTH:

1. Understanding the comparative effectiveness of pharmacological interventions will directly contributes to enhancing patient safety during endotracheal intubation.

2. Identifying the most effective agent for blunting the pressor response ensures the delivery of high-quality care to patients, reduce the risk of cardiovascular complications associated with this procedure.

3. Anesthetic protocols play a pivotal role in ensuring positive perioperative outcomes. This research has the potential to influence and optimize anesthesia protocols. 

4. By providing evidence-based insights into the comparative efficacy of esmolol and Ivabradine, the study will contribute to refining anesthesia practices, promoting standardization, and improving the overall quality of care.
