Dexmedetomidine vs. Remifentanil Undergoing Cataract Surgery in Geriatrics

Dexmedetomidine is an α2-adrenergic receptor agonist used for its sympatholytic effect, providing sedation, analgesia, and cardiovascular stabilization in the perioperative period. Remifentanil is a µ opioid agonist with a rapid onset and short duration of action, which is degraded by plasma esterase in tissues. Investigators aimed to compare the effects of dexmedetomidine and remifentanil infusions on sedation quality, side effects, and surgeon's satisfaction in geriatric outpatients who underwent cataract surgery.
