Key result
Deep-breathing exercises significantly prevented the postoperative decline in sleep quality and duration compared to standard care in patients undergoing coronary artery bypass graft surgery.
Why the study?
Disordered sleep occurs frequently after coronary artery bypass graft surgery and contributes to increased morbidity, mortality, and resource utilization.
Does deep breathing exercises improve postoperative sleep duration and quality in patients undergoing coronary artery bypass graft (CABG)?

Deep-breathing exercises merit routine incorporation into CABG postoperative protocols; extends RCT evidence for nonpharmacologic sleep preservation in cardiac surgery.
Ghorbani et al. (2019) conducted an RCT in Coronary Artery Bypass Graft (CABG) (n=64). Deep-breathing exercises vs. No deep breathing exercises training was evaluated on Postoperative sleep quality score at day 7 (p=<0.001). Deep-breathing exercises significantly prevented the postoperative decline in sleep quality and duration compared to standard care in patients undergoing coronary artery bypass graft surgery.
