Abstract:
Objective To study the impact of the off-pump coronary artery bypass compared to the on-pump coronary artery bypass technique on the rate of acute kidney injury.Methods A retrospective analysis of 824 patients accepted coronary artery bypass surgery in FuWai Hospital Surgical ICU from March 2011 to January 2013.Patients were divided into two groups according to the surgical approach,597 patients in on-pump group and 227 patients in off-pump group.Then compared the difference of acute kidney injury incidence in the two groups.Results 92 patients in the on-pump group occurred AKI,the incidence of AKI was 15.4％.32 patients in the off-pump group occurred AKI,the incidence of AKI was 14.1％.Two groups of patients had no statistical difference in the incidence of AKI,x2 =0.222,P =0.638.Based on the preoperative baseline creatinine clearance levels.We defined normal creatinine clearance (SCR ≥ 60 ml/min),mild renal insufficiency (45 ml/min ＜ SCR ＜60 ml/min),moderate renal dysfunction group(31 ml/min ＜ SCR ＜45 ml/min).Decline with the preoperative creatinine clearance rate,the AKI incidence was elevated significantly,P ＜0.05.Patients with moderate renal insufficiency,offpump patients had lower incidence of AKI than those in on-pump group,P ＜ 0.05.The incidence of renal replacement in the two group patients had no statistical differences.Conclusion The incidence of AKI after coronary artery bypass surgery had no statistical differences with or without pump.In the patients with preoperative moderate renal insufficiency,off-pump can reduce the incidence of AKI,but could not change the kidney the incidence of renal replacement treatment.
