Key result
Preoperative respiratory rehabilitation improves postoperative FVC and FEV1 over control without affecting FEV1/FVC ratio.
Why the study?
CABG carries postoperative complications including declined pulmonary function, prompting investigation into whether preoperative respiratory rehabilitation improves postoperative pulmonary functioning.
Does preoperative respiratory rehabilitation improve postoperative pulmonary functioning in patients undergoing elective CABG?
Population
86 elective CABG patients aged 40-65 years with EF 45% or more
Comparison
Pre- and postoperative respiratory rehabilitation vs postoperative care alone
Design
Randomized clinical trial
Follow-up
4th postoperative day

Does preoperative respiratory rehabilitation improve postoperative pulmonary functioning in patients undergoing elective CABG?
p-value: p=<0.001
Preoperative respiratory rehabilitation significantly improves postoperative lung function (FVC and FEV1) in patients undergoing elective CABG.
Shaukat et al. (2024) conducted an RCT in Coronary artery bypass graft (CABG) (n=86). Preoperative respiratory rehabilitation vs. Standard postoperative care was evaluated on Postoperative pulmonary functioning (FVC, FEV1, and FEV1/FVC ratio) (p=<0.001). Preoperative respiratory rehabilitation significantly improved forced vital capacity (P<0.001) and FEV1 (P=0.006) by postoperative day 4 compared to control, but did not affect the FEV1/FVC ratio.
