Effectiveness of Ancillary Cardio-respiratory Therapeutic Regimen on Post Operative Pulmonary Dysfunction and Quality of Life after CABG surgery – A Pilot Study

Coronary artery bypass graft(CABG) is a major surgical procedure. Approximately 7 million open heart surgeries are performed worldwide annually, and 30% of patients experience major post-operative complications. currently, in India, CABG accounts for more than 60% of all cardiac surgeries performed in India. Generally, after CABG, elevated lactate, and decreased central venous oxygenation promote tissue perfusion, and post-operative pain adversely affects coughing and deep breathing resulting in pulmonary complications, including retention of pulmonary secretion and atelectasis. pneumonia, pleural effusion, respiratory failure, and even death. Combined Non-invasive ventilation therapy, and respiratory and physical exercises have significantly improved the acute phase I of cardio-pulmonary rehabilitation programs and physical functional capacity after CABG. However, critical research gaps persist in preventing the in-patients ’ tissue perfusion and operative pulmonary complications associated with pain, physical functional capacity, and quality of life.

Hypothesis - To emphasize a well-defined ancillary cardio-respiratory therapeutic regimen to increase central venous oxygenation and to reduce post-operative CABG pain in resting and coughing conditions to improve pulmonary functions, physical functional capacity, and quality of life after CABG.
