ABSTRACT

Objective: The aim of this study was to analyze postoperative characteristics risk factors that associated with prolonged invasive mechanical ventilation and hence intensive care unit and hospital stay after off pump coronary artery bypass grafting. Methods: A Prospective, cross sectional, observational study was conducted on 140 patients aged more than 18 years at a tertiary level hospital in India. Results: Bleeding, redo surgery & prolonged duration of inotrope use were found to be strong predictors of prolonged medical stay and care with p values 0.03, 0.048, 0.0001 respectively. Conclusions: Strategies to delineate the patients at risk and to modify these risk factors by prophylactic measures should probably lead to a lower incidence of prolonged mechanical ventilation in patients undergoing isolated off pump CABG surgery.
