AbstractBackground: A variety of spinal surgery procedures are performed on patients with different cardiac, vascular, and respiratory comorbidities. Postoperative pain management is a major determinant of hemodynamic and respiratory status in these patients and promotes clinical results, prevents complications, saves health services, and improves the quality of life of patients. Objectives: We compared the effects of dexmedetomidine and remifentanil on pain control after spinal surgery. Methods: Sixty patients aged 18 - 65 years undergoing spinal surgery were randomized into the two groups of dexmedetomidine and remifentanil. The dexmedetomidine group (group D, n = 30) received dexmedetomidine infusion (0.6 mcg/kg/h), and the remifentanil group (group R, n = 30) received remifentanil infusion (0.1 mcg/kg/min) from induction of anesthesia until extubation. Propofol (1.5 mg/kg) and fentanyl (2mcg/kg) were used to initiate anesthesia, and propofol (100 - 150 mcg/kg/min) was infused to maintain anesthesia. Postoperative pain, hemodynamic parameters, and recovery characteristics were evaluated after surgery. Results: The mean pain intensity in the dexmedetomidine group was significantly lower than in the remifentanil group (2.98 ± 1.29 vs. 3.80 ± 1.1; P < 0.001). Hemodynamic changes in the dexmedetomidine group (MAP: 92.60 ± 5.56, HR: 73.07 ± 7) were less, and their condition was significantly more stable than in the remifentanil group (MAP: 93.85 ± 4.78, HR: 79.15 ± 7.03; P < 0.05). The mean arterial oxygen saturation (O2 sat) in the dexmedetomidine group was significantly higher and more stable than in the remifentanil group (98.87 ± 0.51 vs. 97.92 ± 0.46; P < 0.05). The incidence of nausea and vomiting was significantly lower in the dexmedetomidine group compared to the remifentanil group (P < 0.05). The administration of analgesics in the post-anesthetic care unit (PACU) was significantly higher in the remifentanil group than the dexmedetomidine group (P = 0.016). Conclusions: Anesthetic maintenance with either dexmedetomidine or remifentanil infusion until extubation provided more smooth and hemodynamically stable conditions, without complications. However, dexmedetomidine provides better analgesia, causes a more stable hemodynamic state, and reduces postoperative nausea-vomiting, shivering, and the need for analgesics.en
