Sleep disturbances post coronary artery bypass surgery.
TL;DR: Sleep disturbances during the first month post CABG were reported to be the result of incisional pain, difficulty finding a comfortable position and nocturia, and although less frequent over time, these problems persisted for six months.
Abstract: The purpose of this study was to describe the nature and frequency of sleep pattern disturbances in patients post coronary artery bypass (CABG) surgery. An exploratory design using telephone interviews at one week, one month, three months and six months was used to describe the incidence and nature of sleep disturbances post CABG surgery. Forty-nine patients completed all four measurement times. More than half of the patients reported sleep disturbances at each measurement time. Sleep disturbances during the first month post CABG were reported to be the result of incisional pain, difficulty finding a comfortable position and nocturia. Although less frequent over time, these problems persisted for six months. The authors propose nursing interventions to improve sleep post CABG surgery. Implications for continuing research are discussed.

TL;DR: The purposes of this chapter are to review the literature on dimensions of quality of life and sleep and the relationships between sleep andquality of life among cardiac surgical patients and to propose implications for future research.
Abstract: Cardiac surgical procedures, especially coronary artery bypass surgery used to treat coronary artery disease (CAD), is most frequently utilized in the USA, but utilization of this procedure is increasing in countries that have not in the past used such high-technology health care interventions. Most people experience improvements in multiple dimensions of quality of life, especially those associated with mobility and physical activity. Sleep disturbance is common pre-operatively and extends through the recovery period, but appears to improve over the long term and may contribute to various dimensions of quality of life. The purposes of this chapter are to review the literature on dimensions of quality of life and sleep and the relationships between sleep and quality of life among cardiac surgical patients and to propose implications for future research.

TL;DR: Although there were no age-related differences in the ESS and SF-6D utility values between the two groups, there was a negative correlation between these values in all patients at 5 months after cardiac surgery, which suggested that sleepiness is associated with decreased utility scores in patients at5 months after heart surgery.
Abstract: Background Daytime sleepiness can be assessed by the Epworth Sleepiness Scale (ESS), which is widely used in the field of sleep medicine as a subjective measure of a patient’s sleepiness. Also, health utility assessed by the mean Short-Form Six-Dimension (SF-6D) score, one of several preference-based utility measures, is an important measure in health care. We aimed to examine age-related differences in daytime sleepiness and health utility and their relationship in patients 5 months after cardiac surgery. Methods; This cross-sectional study assessed 51 consecutive cardiac surgery patients who were divided into a middle-aged (<65 years, n = 29) and older-age group (≥65 years, n = 22). The mean ESS and SF-6D utility scores were measured at 5 months after cardiac surgery and compared. In addition, the relationship between ESS and SF-6D utility scores were assessed. Results; There were no significant differences between the middle-aged and older-aged groups in either the mean ESS (5.14 ± 2.96 vs. 4.05 ± 3.23, p = 0.22) or SF-6D utility (0.72 ± 0.14 vs. 0.71 ± 0.10, p = 0.76) scores. However, there was a negative correlation between both values in all of the patients after cardiac surgery (r = −0.41, p = 0.003). Conclusions; Although there were no age-related differences in the ESS and SF-6D utility values between the two groups, there was a negative correlation between these values in all patients at 5 months after cardiac surgery. This suggested that sleepiness is associated with decreased utility scores in patients at 5 months after cardiac surgery.

TL;DR: In this paper, the efficacy of zolpidem for improving post-operative sleep quality among patients with infective endocarditis (IE) and to identify the potential risk factors for impaired sleep quality at 6 months after surgery were investigated.
Abstract: The objective of this study was to investigate the efficacy of zolpidem for improving post-operative sleep quality among patients with infective endocarditis (IE) and to identify the potential risk factors for impaired sleep quality at 6 months after surgery. Patients with IE who underwent surgical treatment were divided into two groups according to zolpidem usage. The Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used to evaluate patients’ sleep quality and daytime sleepiness at baseline, which was the second day after transferal, and at 6 months after surgery. Logistic regression was used to identify potential risk factors. There were 32 patients in the zolpidem group and 42 in the control group. The PSQI and ESS scores at 6 months after surgery were significantly lower than those at baseline in both groups (P = 0.04). Additionally, 9 patients (28%) in the zolpidem group and 22 patients (52%) in the control group suffered poor sleep quality. Multivariate analysis identified age (odds ratio [OR] = 1.26, 95% confidence interval [CI]: 1.12–1.42), baseline PSQI score (OR = 2.66, 95%CI: 1.55–4.65), and no zolpidem usage (OR = 45.48, 95%CI: 3.01–691.23) as independent factors for poor sleep quality. Poor sleep quality after IE surgery was prevalent among patients even 6 months after IE surgery. Age, baseline PSQI score and no zolpidem usage were independently associated with poor sleep quality. Therefore, zolpidem has the potential to be an effective part of a treatment arsenal for poor sleep quality after surgical treatment for IE.
TL;DR: In this article , the authors investigate the sleep quality of patients after valve replacement surgery due to infective endocarditis and identify risk factors for disturbed sleep post hospitalisation, using subjective scale measures, the Pittsburgh sleep quality index (PSQI) and the Epworth sleepiness scale.
Abstract: The current study aimed to investigate the sleep quality of patients after valve replacement surgery due to infective endocarditis and identify risk factors for disturbed sleep post hospitalisation.Eighty patients were assessed postoperatively using subjective scale measures, the Pittsburgh sleep quality index (PSQI) and the Epworth sleepiness scale, and an objective measure, actigraphy. Scale measures were assessed approximately 2 weeks and 6 months after surgery. Actigraphy monitoring was performed for 2 consecutive weeks during hospitalisation. Logistic regression was used to identify risk factors for disturbed sleep.The study population (n = 80) had an average age of 42.8 ± 14.2 years, and 67.5% were male. The median sleep efficiency was 85.3% in week 1 and 86.8% in week 2. The frequency of awakenings was significantly higher in week 1 (20.0 times vs. 19.3 times, p = 0.017). The scale measures showed significant improvement in sleep by 6 months after surgery compared to that during hospitalisation. Multivariable logistic regression analysis suggested that the possible risk factors for disturbed sleep 6 months after surgery included age (OR = 1.479, 95%CI 1.140-1.920) and a few parameters of early postoperative disturbed sleep quality (PSQI: OR = 2.921, 95%CI 1.431-5.963; sleep efficiency: OR = 0.402, 95%CI 0.206-0.783; and average duration of awakenings: OR = 0.006, 95%CI 0.000-0.827).Disturbed sleep quality was witnessed in postoperative patients during hospitalisation and up to 6 months after surgery. Over time, the patients' sleep quality improved significantly. Age and a few early postoperative sleep quality variables were risk factors for disturbed sleep 6 months after surgery.
