Effects of Segmental Breathing Exercise in Patients Awaiting Coronary Artery Bypass Graft Surgery (CABG)

Not Applicable

Completed

• Conditions: Complications Due to Coronary Artery Bypass Graft

• Registration Number: NCT05585138
• Lead Sponsor: Riphah International University

Brief Summary

To determine the effects of preoperative segmental breathing exercise on postoperative pulmonary complications in patients awaiting coronary artery bypass graft surgery (CABG).

This study will be a randomized controlled trial. This study will be conducted in cardiac surgery department at Faisalabad institute of cardiology. sample size will be 44including both male and female. Non- probability purposive sampling technique will be used.

Modified healthy heart questionnaire will be used as a screening tool. Baseline, postoperatively before discharge at week 5 assessment will be done by 6-minute walk test. Subjects in group A (interventional group) will be treated using segmental breathing exercises combined with Conventional Treatment (deep breathing exercise ) and the group B (control group) will be treated with only conventional treatment. Group-A (interventional group) will receive segmental breathing exercises for one month 5 days a week and 2 sessions per day for 15 minutes for each patient. conventional treatment will be for one month 5 days a week 10 to 15 repetitions of deep breathing exercise 2times a day. Dyspnea will be checked baselineand at week5 by modified Borg scale.Sputum cup was used for expectoration of sputum . Quality of life will be checked baseline and at week 5by SF-12 Questionnaire. Outcome variables will be 6MWT, dyspnea, quality of life, oxygen saturation, heart rate, blood pressure and expectoration of sputum. Data will be analyzed on SPSS-25.

Primary Outcome Measures

Name	Time	Method
Change in 6 minute walk test	baseline and week 5	The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.It measures the walking distance of subjects within a fixed time to quantify the functional capacity of the subjects, which refers to the total distance the subjects walked within 6 minutes.
Change in Modified Borg Dyspnea Scale	baseline and week 5	The Modified Borg Dyspnea Scale (MBS) is a 0 to 10 rated numerical score used to measure dyspnea as reported by the patient during submaximal exercise and is routinely administered during six-minute walk testing (6MWT). It starts at number 0 where your breathing is causing you no difficulty at all and progresses through to number 10 where your breathing difficulty is maximal.
Change in short form-12 Health related quality of life questionnaire	baseline and week 5	It is a self-reported outcome measure assessing the impact of health on an individual's everyday life. The SF-12v2 is a health-related quality-of-life questionnaire consisting of twelve questions that measure eight health domains to assess physical and mental health. Physical health-related domains include General Health (GH), Physical Functioning (PF), Role Physical (RP), and Body Pain (BP). short form-12 questionnaire will be used to measure quality of life in CABG patients. Scores range from 0 to 100, with higher scores indicating better physical and mental health functioning.
