| Introduction: Sleep disturbance is common in patients undergoing coronary artery bypass graft surgery and has been subject to concern for more than 30 years. New literature suggests the importance of sleep and rest to restore, protect and promote performance and wellbeing of these patients. Due to the important role nurses play to diagnose such disorders and to help patients get rid of these problems, this study was conducted to determine possible effective factors on sleep quality and quantity of patients after CABG.
Materials & methods: This longitudinal, descriptive and corelational study was conducted on 91 patients admitted to Imam Reza Hospital in Mashhad city during 2005-2006. Subjects were selected according to inclusion and exclusion criteria. Data were collected by interview in three stages:24 hours before surgery as well as 6 weeks and 10 weeks after surgery. Subjective sleep quality was measured in PSQI and sleep quantity was measured in sleep log. The first two interviews were done at the hospital clinic and the last by telephone. Data were analyzed in statistical software of SPSS using student T test, Pearson correlation coefficient and General Linear Model.
Findings: According to uni-variable analysis, variables such as age (p=0.03), aorta clamp time (p=0.003), mechanical ventilation time (p=0.01), hospitalization period (p=0.04), can be effective on sleep quantity of 10 weeks after surgery. Sleep disorder history (p=0.005), suffering from diabetes (p=0.02), using diuretic drugs before surgery (p=0.04), and using ACEI drugs after surgery (p=0.01), can also be effective on sleep quality of 10 weeks after surgery.
Conclusion: Sleep disorder history, using diuretic drugs before surgery and sleep quantity 6 weeks after surgery have been recognized as the most effective factors on sleep quality of 10 weeks after surgery. Quality of life 10 weeks after surgery has been the most effective factor on sleep quantity of 10 weeks after surgery. So, providing appropriate approaches to eliminate and minimize these modifiable factors seems necessary. |
