Background: Dexmedetomidine, an α2-adrenergic agonist, has been reported to modulate inflammatory responses and neuroendocrine stress in surgical settings. This meta-analysis evaluated its effects on serum biochemical markers of inflammation and stress in patients undergoing gastric cancer surgery.
Methods: Literature was retrieved from PubMed, CNKI, Wanfang, and VIP databases. Studies comparing dexmedetomidine anesthesia with conventional regimens in gastric cancer surgery were included. RevMan 5.2 was used for meta-analysis. Outcome indicators included interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), cortisol, epinephrine, adrenocorticotropic hormone (ACTH), heart rate (HR), mean arterial pressure (MAP), and adverse events.
Results: Fifteen studies were analyzed. Compared with controls, dexmedetomidine significantly reduced serum levels of IL-6, TNF-α, cortisol, epinephrine, and ACTH (all P < 0.00001). It also decreased HR, MAP, visual analog scale (VAS) scores, and incidence of adverse reactions.
Conclusion: Dexmedetomidine anesthesia effectively reduces biochemical markers of inflammation and stress in gastric cancer surgery, suggesting its beneficial role in modulating perioperative biochemical responses.
