Do preoperative breathing exercises improve Six-Minute Walk Distance at 1 month postoperatively in patients undergoing elective coronary artery bypass graft surgery?
This study protocol describes a planned randomized trial to assess if preoperative breathing exercises improve 6-minute walk distance and reduce pulmonary complications after CABG.
This RCT will clarify whether preoperative breathing exercises improve early functional recovery after CABG; extends sparse RCT data on prehabilitation.
Purpose: To study the effects of breathing exercises on preventing pulmonary complications in patients undergoing coronary artery bypass graft surgery. Methods: Observing whether preoperative breathing exercises can reduce the incidence of postoperative pulmonary complications in patients undergoing coronary artery bypass graft surgery; observing whether these exercises can improve postoperative arterial oxygen pressure, oxygen saturation, and the distance walked in a six-minute walk test after surgery; as well as reduce hospital stay duration, lower treatment costs, and improve the quality of life as measured by the Short Form-36 Health Survey (SF-36). Design: The study population includes patients undergoing coronary artery bypass graft surgery under general anesthesia; the research center is Capital Medical University Xuanwu Hospital; the sample size is 120. Preoperative standardized breathing exercises are utilized, and the incidence of postoperative pulmonary complications, postoperative arterial blood gases, oxygen saturation, six-minute walk test distances, and comparisons of hospital stay durations and costs will be observed.

Li et al. (2025) conducted an RCT in Coronary artery bypass graft surgery (n=120). Preoperative breathing exercises vs. Budesonide and ipratropium bromide aerosol inhalation alone was evaluated on Six-Minute Walk Distance (6MWD) at 1 month postoperatively. Preoperative breathing exercises will be evaluated to determine their effect on the Six-Minute Walk Distance at 1 month postoperatively in 120 patients undergoing coronary artery bypass graft surgery.
