A Comparison of Off-Pump and On-Pump Coronary Artery Bypass Graft Surgery in Terms of Perioperative Bleeding and Associated Complications ? A Prospective Analytical Study

The relative benefits and risks of performing coronary artery bypass grafting (CABG) with a beating heart technique (off-pump CABG), as compared with cardiopulmonary bypass (on-pump CABG), are not clearly established. Many studies have been carried out regarding its different aspects. We performed a prospective study among the patients who have undergone CABG in Nilratan sircar medical college and hospital, CTVS department in the time period of June, 2012 to March, 2015. Among them 172 patients have been operated for off-pump CABG and 31 patients have been operated under CPB.5 patients needed conversion from off-pump to on-pump during operation. The use of off-pump CABG resulted in reduced rates of allogenic blood transfusion and reoperation for perioperative bleeding. So off-pump CABG may be considered as superior to on-pump CABG in terms of perioperative bleeding and related complications.
