Comparison of insulin infusion protocols targeting 110-140 mg/dL in patients after cardiac surgery

Continuous intravenous insulin infusion (CII) following coronary artery bypass graft (CABG) surgery reduces postoperative complications and hospitalization duration. Because of limited data evaluating outcomes of CII with revised glycemic targets (110-140 mg/dL) in cardiac surgery, this study compared efficacy and safety of two different CII protocols having revised targets. This is a retrospective study comparing two different protocols between August 2009 and March 2010. Protocol 1 consists of four algorithms, and Protocol 2 is a table to adjust CII. Blood glucose (BG) and CII rates were recorded for 48 h postoperatively or CII discontinuation. Efficacy was defined by the percentage of BG values in the target range, and safety was defined by the percentage of BG values
