Pre-operative Respiratory Rehabilitation in Coronary Artery Bypass Graft Patients

Not Applicable

Completed

• Conditions: Respiratory Rehabilitation
• Interventions: Other: Respiratory rehabilitation and out of bed mobilization; Other: conventional treatment

• Registration Number: NCT05736770
• Lead Sponsor: Riphah International University

Brief Summary

To compare the effects of conventional preoperative respiratory rehabilitation and specific preoperative respiratory rehabilitation program on pulmonary functions in coronary artery bypass graft patients.

Detailed Description

After cardiac surgeries many postoperative changes occur that lead to pulmonary complication such as respiratory changes, functional capacity of lungs and gaseous changes that leads to hypoxemia and ischemic injury of lungs. CABG, although a successful procedure, post operative pulmonary complications still pursue a big challenge to the health and fitness of the patients. Although post operative complications have been managed in in-patient setup post CABG, there are pre-operative measures on the rise to prevent the complications to occur after CABG.

This study will contribute in describing the rate of improvement in pulmonary functions with rehabilitation program including preoperative out of bed mobilization, active cycle breathing techniques, forced expiratory technique and volume-based incentive spirometry as compared to the conventional treatment of flow-based incentive spirometry and chest percussion in prevention of post operative pulmonary complications occurring after CABG leading to delayed recovery of patients.

Arm && Interventions

Group	Intervention	Description
Respiratory rehabilitation and out of bed mobilization group	Respiratory rehabilitation and out of bed mobilization	The Respiratory rehabilitation and out of bed mobilization group will perform 4 exercises.
Conventional exercise program group	conventional treatment	The conventional exercises program will perform conventional exercises

Primary Outcome Measures

Name	Time	Method
Ratio of Forced expiratory volume in 1 second and Forced Vital Capacity (FEV1/FVC)	4th postoperative day of coronary artery bypass graft (CABG)	FEV1/FVC: The FEV1/FVC Ratio (FEV1%) parameter is calculated by dividing the measured FEV1 value by the measured FVC value. In healthy adults of the same gender, height, and age, the normal Predicted percentage should be between 70% and 85.
Forced expiratory volume in one second (FEV1)	4th postoperative day of coronary artery bypass graft (CABG)	The Forced Expiratory Volume in 1 Second parameter measures the volume of air that was exhaled into the mouthpiece in the first second after a full inhalation. The normal test values range between 80% and 120% of the average (predicted) values.
Forced Vital Capacity (FVC)	4th postoperative day of coronary artery bypass graft (CABG)	Forced Vital Capacity measures the total volume of air that you were able to blow forcefully into the mouthpiece following a full inhalation

Secondary Outcome Measures

Name	Time	Method
Borg scale	4th postoperative day of coronary artery bypass graft (CABG)	The Borg Rating of Perceived Exertion (RPE) scale is a tool for measuring an individual's effort and exertion, breathlessness and fatigue during physical work. Patients are asked to tell the whole feeling of exertion including leg pain and shortness of breath and it is marked on a number from 6-20, where 6 indicates "no exertion at all" and 20 indicates "maximal exertion".
6-minute walk test (6MWT)	4th postoperative day of coronary artery bypass graft (CABG)	six minutes walk test (6MWT) is test used to measure functional exercise capacity of patients with cardiovascular and/or pulmonary disease. In this test, patient performs walk for 6 minutes while time being counted on stopwatch. The patient can take rest between the walk, but the timer keeps on running and the rest period is counted. At the end of the test, patient's level of exertion is noted, and the distance measured is recorded. The 6MWT distance values for a healthy person are 400-700m.
