Abstract:

Introduction: In general, after coronary artery bypass operation, 39% to 69% of patients experience insomnia, poor sleep quality, and lack of sleep continuity (frequent awakening, difficult sleep, restless sleep, and early morning awakening). The aim of this study was to investigate the sleep quality of patients on the preoperative 1st day, postoperative 3rd day, postoperative 7th day, and postoperative 30th day of a coronary artery bypass operation. Patients and Methods: Ninety-nine patients who underwent elective coronary bypass operation in our clinic between January 2017 and January 2018 were included in this study. The patients were assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire on the preoperative 1st day, postoperative 3rd day, postoperative 7th day, and postoperative 30th day. Results: The mean age of total patients was 61.5 ± 11.4 years (range: 35-80); 67 were male and 22 were female. According to the results of the PSQI survey conducted on patients, there is a statistically significant increase in sleep quality on the postoperative 3rd day in comparison with the results of the preoperative 1st day evaluation. According to the postoperative 3rd day evaluation, there is a statistically significant decrease in sleep quality compared with the postoperative 7th and 30th days. Also, the PSQI scores of the postoperative period have a statistically significant correlation with age (p= 0.002, p= 0.004, p= 0.009). Conclusion: Although sleep disturbance has a significant impact on the physical and emotional adaptation and recovery after coronary artery bypass operation, the number of studies conducted on this subject is quite low.
