Effect of Perioperative Dexmedetomidine on Chronic Post-Surgical Pain

Dexmedetomidine Hydrochloride Nasal Spray Dexmedetomidine is a selective alpha-2 adrenergic agonist primarily used for its sedative, anxiolytic, and analgesic effects. It works by inhibiting the release of norepinephrine in the central nervous system, leading to sedation, decreased anxiety, and reduced pain sensitivity. When used intranasally, it can offer an effective, non-invasive method for sedating patients and improving sleep quality, particularly in perioperative settings.

The saline solution will be used as a placebo, and the same device will be employed for intranasal administration.
