Investigation of sleep and affecting factors in coronary artery bypass graft surgery

Abstract

Objective: The aim of this study was to evaluate the sleep perceptions and factors influencing sleep during the early postoperative period in patients who underwent coronary artery bypass graft (CABG) surgery. Materials and Methods: This descriptive study included 92 volunteer patients who underwent CABG surgery between September 1, 2019, and February 1, 2020. Data were collected using the 2nd, 3rd, 4th Richards-Campbell sleep questionnaire (RCSQ) and a postoperative sleep-affecting factors form. The study was reported using the STROBE checklist. Statistical significance was set at p<0.05. Results: The mean age of the participating patients was 60.72±8.95, with 68.5% aged ≤65 years, 73.9% male, and 85.9% having a body mass index ≥25 kg/m2. The RCSQ total sleep perception scores of the patients were evaluated as 15.88±12.50 on the second day, 24.76±7.50 on the third day, and 32.35±7.56 on the fourth day after the postoperative period. When comparing the mean RCSQ scores with the descriptive characteristics of the patients, no statistically significant difference was found (p>0.05). During the postoperative period, patients reported that factors such as pain, frequent medical interventions, fear of sudden deterioration of their condition, fear of death, and being away from home in an unfamiliar environment had a significant impact on their sleep. Conclusion: The mean RCSQ scores of patients who underwent CABG surgery were found to be very poor on the second and third days postoperatively and worsened on the fourth day.
