ABSTRACT

Back ground: We aimed to identify incidence, risk factors and outcome of post operative bleeding after off pump coronary artery bypass grafting. Many previous studies involved cardiac surgeries with cardio pulmonary bypass. We concentrated on isolated off pump elective CABG and its post operative bleeding incidence, risk factors and other adverse events due to the bleeding, because beating heart coronary bypass is popular and commonly used now days. Methods: A Prospective, cross sectional, observational study conducted on 140 patients aged more than 18years at tertiary level super-speciality hospital in Bangalore. Results: Post operative bleeding associated with high incidence of blood transfusion, redo surgery, higher duration of ICU stay and mortality (p=0.003). Predictors old age, DM, CKD, anemia, hypoalbuminemia, higher ASA and NYHA class, high EuroSCORE, poor ejection fraction were found to be strongest predictors of post operative bleeding with statistical significance and hence poor outcome. Conclusion: Severe post operative bleeding in off pump CABG leads to more blood transfusion and redo surgery causing significant morbidity and mortality. Currently, prediction and identification of risk factors which associated with it helps better planning of patient management and reduction in morbidity and mortality.
