Abstract

Introduction: Disordered sleep occurs frequently in patients who have undergone coronary bypass graft surgery, and it contributes to increased morbidity, mortality, and resource utilization. The present study aimed to determine the effects of deep-breathing exercises on postoperative sleep duration and quality in patients undergoing coronary artery bypass graft.Methods: This study was a clinical trial. The study sample included 64 patients who were coronary artery bypass graft hospitalized from January 2015 to April 2015 in Qazvin Booali-Sina hospital. The patients were selected by convenient sampling and then the participants were randomly allocated to the intervention and control groups. The baseline and postoperative (day 7) sleep duration and quality metrics were measured. The St Mary's Hospital Sleep Questionnaire was used to evaluate sleep quality in two groups.Results: Baseline night sleep duration was 5.72 (1.63) hours in the control group and 5.58 (1.07) hours in the intervention group. The initial findings showed that the mean of sleep quality score of patients in the intervention and control groups were 19.72 (2.68) and 18.22 (3.81) respectively. These measurements did not decline postoperatively in the intervention group while night sleep duration and quality declined in the control group. Deep breathing exercise program had a significant effect on sleep quality score in the intervention group compared to the control group.Conclusion: The results indicated that deep breathing exercises prevent decline in sleep quality postoperatively. It seems to be a safe method with no side effects for these patients. Furthermore, it is a simple method to implement and does not impose a high cost.

Highlights

Sleep disorders are the most common health problem for coronary artery bypass graft (CABG) patients
Chien et al, supported the hypothesis that the cognitive behavioral intervention combined with a breathing relaxation exercise could improve sleep quality and heart rate variability in patients with major depression[16] deep breathing exercises have an obvious impact on preventing further postoperative pulmonary problems in cardiac surgery,[17,18] few investigations have focused on the association between deep breathing exercise and sleep quality,[19] with almost no studies investigating the influence of deep breathing exercises on sleep duration and quality among patients undergoing coronary artery bypass graft during hospitalization
Patients undergoing CABG surgery often complain about sleep disturbances and short sleep duration; poor sleep is a major physical distress after surgery.[24] our study focused on the effect of deep breathing exercise on the sleep duration and quality in patients undergoing CABG

Summary

Introduction

Sleep disorders are the most common health problem for coronary artery bypass graft (CABG) patients This disorder has been explored for more than 30 years[1] and is known to have a great impact on the emergence of disabilities and death, as well as, longer hospitalization period and the ensuing costs.[2] Inadequate sleep weakens the immunity system and leads to the decrease in the performance of hypothalamus, pituitary and adrenal glands days after operation,[3] which enhance the risk of developing impaired Glucose tolerance, higher blood pressure, and the probability of the cardiovascular diseases.[4,5] The decline of physical performance, a decrease in the concentration and learning abilities are among the other side effects of having insufficient sleep.[3] Sleep disorders are the most important issues of health care.
