Patients undergoing total knee arthroplasty (TKA) often experience a difficult recovery due to severe postoperative pain. Using a multimodal pain management protocol, a blinded, randomized, placebo-controlled study was designed to evaluate the efficacy of patient-selected music on reducing perceived pain. Thirty patients undergoing primary unilateral TKA were enrolled and randomized into the music group (15 patients) or the control group (15 patients). Postoperative pain scores, assessed with the visual analog scale, indicated the music group experienced less pain at 3 and 24 hours postoperatively than did the nonmusic group (at 3 hours: 1.47+/-1.39 versus 3.87+/-3.44, P=.01; at 24 hours: 2.41+/-1.67 versus 4.03+/-2.89, P=.04). Intraoperative music provides an inexpensive nonpharmacological option to further reduce postoperative pain.
接受全膝关节置换术（TKA）的患者常因术后剧痛而恢复困难。采用多模式疼痛管理方案，设计了一项双盲、随机、安慰剂对照研究，以评估患者自选音乐对减轻疼痛感知的疗效。30例接受初次单侧TKA的患者入组并随机分为音乐组（15例患者）和对照组（15例患者）。用视觉模拟量表评估的术后疼痛评分显示，音乐组术后3小时和24小时的疼痛程度低于非音乐组（3小时时：1.47±1.39对3.87±3.44，P = 0.01；24小时时：2.41±1.67对4.03±2.89，P = 0.04）。术中音乐提供了一种廉价的非药物选择，可进一步减轻术后疼痛。
