Comparison of the Effects of Remifentanil and Dexmedetomidine Administered Under General Anesthesia in Rhinoplasty

Remifentanil is an opioid; it has sedative, analgesic, and sympatholytic properties.

"Studies show that dexmedetomidine is superior to currently commonly used remifentanil in terms of intraoperative blood pressure control and postoperative pain.~Dexmedetomidine, an alpha-2-adrenoceptor agonist, has sympatholytic, sedative, anesthetic, analgesic, and vasoconstrictor effects. It lowers blood pressure by decreasing plasma norepinephrine and epinephrine levels, thereby reducing intraoperative bleeding. Dexmedetomidine is defined as an analgesic that is now widely used to induce and maintain anesthesia and to control postoperative pain, and is defined as an analgesic that does not cause respiratory depression and neurocognitive impairment. Many studies have shown that the use of perioperative dexmedetomidine reduces the stress response to anesthetic induction and surgery and provides hemodynamic stability."
