Abstract

Objective:To evaluate the Effectiveness of Pre-operative Respiratory Muscle Training versus Conventional Treatment for Improving post-operative pulmonary health after Coronary Artery Bypass Graft Surgery (CABG).Methods:A Prospective Randomized clinical trial was performed on sixty patients who underwent elective CABG at Faisalabad Institute of Cardiology. At the time of admission all patients were subjected to 6-minutes’ walk test (6MWT) as baseline. The subjects were then divided into two groups. The Group-I was subjected to respiratory muscle training whereas the Group-2 received the routine preoperative care. The 6-minute walk test (6MWT) was then repeated a day before surgery (pre-operative) and before discharge (post-operatively). Duration of post-operative mechanical ventilation, oxygen therapy and hospital stay were also noted as outcome measures of this study.Results:The pre-operative and post-operative readings showed that the patients in the interventional group performed better than the control group in their 6MWT with P-value of less than 0.05. Similarly the interventional group had shorter duration of mechanical ventilation, dependence on oxygen therapy and postoperative hospital stay as compared with the control group showing P-values below 0.05.Conclusion:The results showed that respiratory muscle training results in improved postoperative functional capacity and reduces of hospital stay.

Highlights

The available literature supports that one of the major cause of post-operative pulmonary problems which increases the duration of mechanical ventilation and oxygen therapy was poor preoperative pulmonary health
There is need to find if any improvement of pre-operative pulmonary health in patients selected for Coronary Artery Bypass Grafting has impact on outcome of surgery

Summary

Introduction

The available literature supports that one of the major cause of post-operative pulmonary problems which increases the duration of mechanical ventilation and oxygen therapy was poor preoperative pulmonary health. There is need to find if any improvement of pre-operative pulmonary health in patients selected for Coronary Artery Bypass Grafting has impact on outcome of surgery. The purpose of this study was to evaluate the effectiveness of preoperative inspiratory muscle training in patients undergoing Coronary Artery Bypass Grafting and assess their pulmonary status after surgery.
