Brief Summary
Dexmedetomidine, an alpha-2 adrenergic agonist, has been shown to provide several benefits during endotracheal intubation:
- 1.\_Reduced anxiety and stress\_: Dexmedetomidine's anxiolytic and sedative effects help reduce anxiety and stress associated with endotracheal intubation.
- 2.\_Improved intubating conditions\_: Dexmedetomidine can improve intubating conditions by reducing the incidence of coughing, bucking, and laryngospasm.
- 3.\_Decreased hemodynamic responses\_: Dexmedetomidine can attenuate the hemodynamic responses to intubation, including tachycardia, hypertension, and increased cardiac output.
- 4.\_Increased ease of intubation\_: Dexmedetomidine can facilitate smoother and easier intubation by reducing the need for additional anesthetics or muscle relaxants.
- 5.\_Decreased heart rate\_: Dexmedetomidine can cause a decrease in heart rate due to its effects on the sympathetic nervous system.
- 6.\_Decreased blood pressure\_: Dexmedetomidine can also cause a decrease in blood pressure due to its vasodilatory effects.
- 7.\_Increased sedation\_: Dexmedetomidine's sedative effects can help reduce anxiety and stress during intubation.
- 8.\_Reduced respiratory rate\_: Dexmedetomidine can cause a decrease in respiratory rate due to its effects on the respiratory centers in the brain.
- 9.\_Improved patient comfort\_: Dexmedetomidine's sedative and anxiolytic effects can improve patient comfort during intubation.
- 10.\_Reduced need for additional anesthetics\_: Dexmedetomidine can reduce the need for additional anesthetics or muscle relaxants during intubation.
- 11.\_Decreased risk of complications\_: Dexmedetomidine's effects on hemodynamic responses and respiratory rate can decrease the risk of complications during intubation.

Outcome Measures
Primary Outcomes (1)
Mean Arterial Pressure (MAP)
The primary outcome is to measure the change in Mean Arterial Pressure before endotracheal intubation and 5 minutes after intubation. An increase or decrease in MAP of 20 mmHg of patient's baseline MAP within 5 minutes of endotracheal intubation will be considered significant in our study. The focus is on whether Dexmedetomidine maintain MAP with 20mmhg of patient's baseline reading.
At 5 minutes after laryngoscopy and endotracheal intubation.

Study Arms (2)
Intervention group/Group D
EXPERIMENTALIntervention group: Group D patients will be administer 0.5 mcg/kg dexmedetomidine intravenously over 10 min preoperatively.
Control group/Group C
PLACEBO COMPARATORControl group: Group C patients will be administer the same volume of normal saline (also intravenously for 10 min)
Interventions
In this study, the intervention involve administrating 0.5 mcg/kg of Inj dexmedetomidine intravenously over 10 min to patients in intervention group/group D 2 minutes prior to Endotracheal intubation using laryngoscopy aiming to asses its efficacy in attenuating the pressor response to laryngoscopy.
The Placebo group / group C will be administer Normal Saline without any active medication over 10 min to patients, 2 minutes prior to Endotracheal intubation using laryngoscopy to compare its effect to those of Dexmedetomidine in attenuating the pressor response to laryngoscopy.
