The purposes of this study were to investigate the relationship of postoperative anxiety and pain following coronary artery bypass graft (CABG) surgery, and to determine the effects of level of anxiety, demographic, and other factors on the level of postoperative pain. Pain intensity, sensory pain, and affective pain were measured along with anxiety on postoperative day 2 and day 3 by the McGill Pain Questionnaire Subscales (PPI, PRIS, and PRIA) and State Anxiety Inventory Scale, respectively. A direct relationship of anxiety with pain was found over time with the highest relationship on postoperative day 2 (r = 0.235-0.492, P < 0.001). A significant interaction between time and level of anxiety on affective pain was specific to postoperative day 2 (P < 0.01). Significant differences by level of anxiety and time were reported. Factors of age, gender, marital status, number of previous surgeries, and operation time had no effect on the level of postoperative pain.
本研究的目的是调查冠状动脉旁路移植术（CABG）后焦虑与疼痛之间的关系，并确定焦虑水平、人口统计学因素及其他因素对术后疼痛程度的影响。分别在术后第2天和第3天，通过麦吉尔疼痛问卷分量表（PPI、PRIS和PRIA）和状态焦虑量表测量疼痛强度、感觉性疼痛和情感性疼痛以及焦虑程度。随着时间推移，发现焦虑与疼痛之间存在直接关系，术后第2天两者关系最为密切（r = 0.235 - 0.492，P < 0.001）。情感性疼痛方面，时间与焦虑水平之间存在显著交互作用，这一作用在术后第2天具有特异性（P < 0.01）。报告了焦虑水平和时间方面的显著差异。年龄、性别、婚姻状况、既往手术次数和手术时间等因素对术后疼痛程度没有影响。
