Comparison of On-pump and Off-pump Coronary Artery Bypass Grafting for Patients with High-Risk Coronary Artery Disease / 中国微创外科杂志

ABSTRACT

0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.
