The aim of this meta-analysis is to examine the effects of dexmedetomidine on serum inflammatory markers when administered perioperatively. We searched multiple electronic databases for relevant research papers, and carried out meta-analyses of weighted mean differences and interpreted in the light of statistical heterogeneity (I-2). Fifteen RCTs recruiting 641 patients were included. Dexmedetomidine treatment significantly decreased interleukin-6 (IL-6), IL-8 and tumor necrosis factor-alpha (TNF-alpha) levels with mean differences [95% CI] in the changes from baseline between dexmedetomidine treated and controls of -25.14 [-35.29, -15.00]; P < 0.00001 (for IL-6), -5.69 [-10.77, -0.60]; P < 0.04 (for IL-8), and -20.30 [-30.93, -9.67]; P < 0.0002 (for TNF-alpha) immediately after surgery; and -41.55 [-57.41, -25.70]; P < 0.00001 (IL-6), -6.46 [-10.83, -2.08]; P < 0.005 (IL-8), and -14.67 [-22.61, -6.73]; P < 0.0003 (TNF-alpha) on postoperative day 1 (random effects). IL-10 levels were found to increase significantly a day after surgery (8.33 [3.31, 13.36]; P = 0.001). Subgroup analyses did not reveal significant differences. In conclusion, perioperative adjunctive use of dexmedetomidine substantially decreases serum IL-6, IL-8 and TNF-alpha levels.
