Objective  To evaluate the clinical efficacy of dexmedetomidine in perioperative management of on-pump cardiac surgery. Methods  Randomized controlled trials (RCTs) were identified through a systematic literature search of PubMed, EBSCO, Web of Science, Cochrane Library, CBM, CNKI, Wanfang Database (up to December 2016). RevMan 5.3 software was used for meta-analysis. Results  Sixteen studies with 1 432 patients were included. Dexmedetomidine significantly decreased the risk of postoperative delirium (RR=0.28, 95% CI 0.18 to 0.44, P<0.000 01) and postoperative atrial fibrillation (RR=0.65, 95% CI 0.44 to 0.98, P=0.04) compared with the controls. The duration of intubation (RR=–1.96, 95% CI –2.07 to –1.86, P<0.000 01), length of ICU stay (RR=–0.49, 95% CI –0.74, –0.24, P=0.000 1) and hospital stay (RR=–1.24, 95% CI –2.26 to –0.22, P=0.02) in the dexmedetomidine group were significantly shorter than those of the control group. In addition, dexmedetomidine was shown to improve the score of the the Montreal Cognitive Assessment (RR=0.88, 95% CI 0.42 to 1.35, P=0.000 2) compared to the control group. Conclusion  Dexmedetomidine can reduce the complications after cardiac surgery, which is safe and effective. However, more studies with good methodologic quality and large samples are still needed to make further assessment.
