Surgical placement of temporary epicardial pacing wires (EPWs) onto the epicardial surface of the heart is standard practice during cardiac surgery. The purpose of this study was to determine the intensity and quality of pain and sensations experienced during the procedure of EPWs removal for coronary artery bypass graft (CABG) patients. A descriptive study, incorporating the McGill Pain Questionnaire-short form and visual analogue scales, was used with 100 CABG patients requiring EPW removal. The pain intensity was reported as mild (47%), while the main sensation experienced was pulling (70%). Age, gender, previous cardiac surgery and EPW removal experience, and use of analgesics did not influence the pain and sensations experienced. However, subjects who had EPWs removed on post-operative day five or earlier did present with higher MPQ-SF affective and combined scores. CABG patients can be prepared for EPW removal by providing information that the procedure is a mildly painful, pulling sensation.
在心脏手术期间，将临时心外膜起搏导线（EPW）手术放置在心脏的心外膜表面是标准操作。本研究的目的是确定冠状动脉旁路移植术（CABG）患者在拔除EPW过程中所经历的疼痛强度和性质以及感觉。一项描述性研究采用了麦吉尔疼痛问卷简表和视觉模拟量表，纳入了100例需要拔除EPW的CABG患者。报告的疼痛强度为轻度（47%），而主要经历的感觉是牵拉感（70%）。年龄、性别、既往心脏手术和拔除EPW的经验以及镇痛药的使用均不影响所经历的疼痛和感觉。然而，在术后第5天或更早拔除EPW的受试者确实表现出较高的麦吉尔疼痛问卷简表情感维度和综合得分。可以通过告知CABG患者该操作会带来轻度疼痛的牵拉感，让他们为拔除EPW做好准备。
