Effect of CABG on Respiratory Muscle Strength and PEFR Values: A Pilot Study

Coronary artery bypass grafting remains the foremost choice of surgery in patients with coronary artery diseases despite several other advanced surgical procedures. After surgery, there are several complications, such as pain, reduced cough reflex and reduction in QOL. Aim: The study aims to record some more post - operative complications such as changes in functional capacity, respiratory muscle strength and compromised endurance. Settings and Design: It is a pilot observational study. The study is undertaken in the Cardiac care unit in a tertiary care teaching hospital. Methods and Material: Individuals between age group 45 - 65 were included in the study without any surgical complication and presence of any comorbidities. An analysis was conducted on 9 patients who underwent CABG. Statistical analysis: Results are analysed using Instastats Graph pad version 3. Results: The mean of preop - MIP values is 74.33 and the post MIP value is 67.45 showing 9.25% reduction. The mean value of preop - MEP is 77, and the post - op MEP mean value is 71.55, showing 8.5% reduction. Similarly, 12.13% reduction seen in PEFR value post - operatively. Conclusion: There is a significant reduction in MIP, MEP and PEFR values in CABG patients.
