Summary
Background.Coronary artery bypass grafting surgery, performed using off-pump grafting (OPCAB) has been reported to be associated with a lower number complications and shorter hospital stays.
Methods. We have retrospectively compared the results of coronary artery bypass grafting surgery in two group of patients, operated on without or with cardiopulmonary bypass (CABG). The end-points were: duration of mechanical ventilation, perioperative bleeding, duration of ICU stay, duration of hospitalization, and the requirement for inotropic support.
Results. The duration of mechanical ventilation was similar in both groups. OPCAB patients received a lower number of bypass grafts (2.2±0.8 vs. 3.2±0.8 in the CABG group). The time spent in the ICU and the duration of hospital stay were shorter in the OPCAB group (1.4±1.5 vs. 1.7±2.2 and 8.4±4.3 vs. 9.2±4.8, respectively). 18% of patients in the CABG group required inotropic support, compared to 9% in the OPCAB group (p<0.001), and 43% of CABG patients required blood transfusion, vs. 23.6% in the OPCAB group (p<0.001)
Conclusion. The results indicate that off-pump bypass surgery may be associated with lower cardiovascular compromise in the early postoperative period, and shorter ICU and hospital stays.
