ObjectiveTo assess the effect of perioperative glucose-insulin-potassium (GIK) infusions on the prognosis in patients undergoing coronary artery bypass grafting.MethodsElectronic databases including Cochrane library (Issue 3, 2011), Pubmed, EMbase, Highwire, CBM and CNKI were searched. A meta-analysis of all randomized controlled trials (RCTs) comparing GIK with control in coronary artery bypass grafting was performed. Study selection and meta-analysis were conducted which according to the Cochrane Handbook for systematic reviews. Date were extracted from these trials by 3 reviewers independently and analyzed by RevMan5.0 software.ResultsA total of 9 RCTs including 1029 patients were assessed in this study. GIK infusion was associated with significantly fewer perioperative myocardial infarctions (RR = 0.59, 95%CI: 0.38 - 0.91, P = 0.02), less inotropic support requirement (RR = 0.44, 95%CI: 0.35 - 0.56, P < 0.01), and increase the incidence of postoperative atrial fibrillation (RR = 1.23, 95%CI: 1.05 - 1.43, P = 0.009).ConclusionsGIK significantly reduces myocardial injury and improves cardiac function in patients undergoing coronary artery bypass grafting, but also increases the incidence of postoperative atrial fibrillation.
