Comparative study between different pulmonary rehabilitation programs in patients undergoing coronary artery bypass graft

Background: Coronary artery bypass graft (CABG) is still associated with frequent development of postoperative pulmonary complications, which are particularly concerning given its link to increased patient morbidity and mortality and resource utilization. Aim of the work: The aim of this study was to compare between the effects of different rehabilitation programs post coronary artery bypass graft. Subjects and Methodology: Forty-five patients of both sexes (22 women and 23 men) who underwent coronary artery bypass graft were enrolled in that study for five days while inpatient period. Their ages ranged from 45-55 years. They were assigned into three groups with equal numbers (control group, Buteyko breathing technique group and incentive spirometer group). Arterial blood gases (PaO2, PH, Hco3 and PaCO2) were measured for the three groups at the beginning of the study (1st day postoperative) and after the end of training (5thday postoperative). Results: There was significant improvement in arterial blood gases including an increase in PaO2 and PH, while there was significant decrease in PaCO2 and Hco3,(P<0.05) for three groups. Significant difference was noted between three groups postoperatively, in favor of incentive spirometer group. Conclusion: Both Buteyko breathing technique and incentive spirometer induce significant improvement in arterial blood gases after Coronary Artery Bypass Graft surgery, in favor of incentive spirometer.
