Abstract 【Objective】 To explore the effects of dexmedetomidine (Dex) combined with butorphanol on postoperative analgesia and oxidative stress response in patients undergoing esophagectomy.【Methods】 A total of 102 patients undergoing esophagectomy were randomly divided into a control group and an observation group, with 51 patients in each group. The control group received postoperative analgesia with butorphanol and sufentanil, while the observation group received butorphanol combined with Dex. Awakening time, hemodynamic parameters [heart rate (HR), mean arterial pressure (MAP)], stress response markers [adrenaline (Adr), cortisol (Cor)], pain levels, and adverse reactions were compared between the two groups.【Results】The awakening time and postoperative recovery room stay in the observation group were shorter than those in the control group (P<0.05). In both groups, HR and MAP at 6 minutes after anesthesia (T1) and 2 minutes after surgery (T2) were higher than those before anesthesia (T0) (P<0.05), while HR and MAP at T2 were lower than those at T1 (P<0.05). HR and MAP at T1 and T2 were significantly lower in the observation group compared to the control group (P<0.05). Adr and Cor levels at 24 hours and 36 hours postoperatively were higher than preoperative levels in both groups (P<0.05), with levels at 36 hours showing lower than those at 24 hours (P<0.05). The observation group had significantly lower Adr and Cor levels at 24 hours and 36 hours postoperatively compared to the control group (P<0.05). Visual Analog Scale (VAS) scores at 3, 9, 24, and 36 hours postoperatively were higher than preoperative levels in both groups (P<0.05), showing an initial increase followed by a decrease. The VAS scores of the observation group at each time period after surgery were lower than those of the control group (P<0.05). There was no statistically significant difference in the overall incidence of adverse reactions between the two groups (P>0.05).【Conclusion】 Dex combined with butorphanol in esophagectomy stabilizes postoperative hemodynamic parameters, accelerates patient recovery, suppresses perioperative stress response, reduces postoperative pain, and demonstrates good safety.
