 This study tested the hypothesis that perioperative esmolol administration resulted in decreased postoperative pain and improved hemodynamic balance in patients with rhinoplasty. The results showed that intraoperative esmolol infusion reduced postoperative pain, decreased the need for analgesics, and provided hemodynamic stability in the first three hours of post-rinoplasty surgery.
