This study examined the self-reported sleep patterns of adult patients undergoing coronary artery bypass graft (CABG) surgery and the relationship between their perceived illness-related stress and sleep disturbances. Twenty-four patients completed data at all three collection points: preadmission, and the third and sixth postoperative mornings. Patients responded to the Verran/Snyder-Halpern Sleep Scale and the Carr and Powers Stressor Scale for patients having CABG. By use of a within-subject, one-factor, repeated measures analysis of variance, statistically significant differences were found in each of the three sleep dimensions measured over time (disturbance, effectiveness, and supplementation). With the Pearson correlation, the hypothesis that sleep disturbances in patients having open-heart surgery are related to psychologic stress associated with illness was not supported. Additional analyses indicated that hospital and illness-related stress, duration of cardiopulmonary bypass, anesthesia time, and sleep medication were related to patients' sleep disturbance, effectiveness, or supplementation in different ways and at different times during the study periods.
本研究调查了接受冠状动脉搭桥术（CABG）的成年患者自我报告的睡眠模式，以及他们感知到的疾病相关压力与睡眠障碍之间的关系。24名患者在所有三个收集点完成了数据收集：入院前、术后第三天早晨和术后第六天早晨。患者对Verran/Snyder-Halpern睡眠量表以及针对接受CABG手术患者的Carr和Powers应激源量表进行了回答。通过使用受试者内单因素重复测量方差分析，发现在随时间测量的三个睡眠维度（干扰、有效性和补充）中的每一个维度上都存在统计学上的显著差异。通过Pearson相关性分析，心脏直视手术患者的睡眠障碍与疾病相关心理压力有关这一假设未得到支持。进一步分析表明，在研究期间，医院和疾病相关压力、体外循环持续时间、麻醉时间和睡眠药物以不同方式、在不同时间与患者的睡眠干扰、有效性或补充相关。
