With recent developments in the field of analgesia, the question arises whether there is a role for placing local anesthetics, nonsteroidal anti-inflammatory drugs, or both into the breast implant pocket. The objective of this study was to test the effectiveness of locally administered intraoperative ketorolac and bupivacaine with epinephrine at reducing pain in the postoperative period. The study was a prospective, randomized, double-blind clinical trial. One hundred consecutive retropectoral breast augmentation patients were enrolled, and informed consent was obtained. A standard anesthetic protocol and surgical procedure were followed. Normal saline, ketorolac alone (30 mg), bupivacaine alone (150 mg), or ketorolac and bupivacaine (30 mg and 150 mg respectively) were placed into the implant pocket before implant insertion. All patients completed the study. The power of this study to detect a 20 percent difference with respect to the primary outcome was 0.90 and confidence intervals of 95 percent were used to determine significance. The primary outcome was pain as measured by the visual analogue pain scale. The secondary outcome was time spent in the recovery room. Intraoperative placement of ketorolac combined with bupivacaine reduced pain in the postoperative period. It did not appear that anesthesiologist, anesthesia time, surgeon, operating room time, difficulty of dissection, breast incision, or implant size had a significant effect on postoperative pain. There was a trend that the ketorolac and bupivacaine patients spent less time in the recovery room and used fewer analgesics postoperatively than the other patients. There were no hematomas requiring reoperation and no complications. Locally administered intraoperative ketorolac and bupivacaine with epinephrine significantly reduced pain in the postoperative period.
随着镇痛领域的最新进展,出现了一个问题,即在乳房植入物腔隙中放置局部麻醉药、非甾体抗炎药或两者是否有作用。本研究的目的是测试术中局部给予酮咯酸和布比卡因加肾上腺素在减轻术后疼痛方面的有效性。该研究是一项前瞻性、随机、双盲临床试验。连续纳入100例胸后入路隆乳患者,并获得知情同意。遵循标准的麻醉方案和手术程序。在植入假体前,将生理盐水、单独的酮咯酸(30毫克)、单独的布比卡因(150毫克)或酮咯酸和布比卡因(分别为30毫克和150毫克)放入假体腔隙。所有患者均完成了研究。本研究检测主要结局20%差异的效能为0.90,并使用95%的置信区间来确定显著性。主要结局是通过视觉模拟疼痛量表测量的疼痛。次要结局是在恢复室停留的时间。术中放置酮咯酸联合布比卡因可减轻术后疼痛。麻醉医生、麻醉时间、外科医生、手术室时间、解剖难度、乳房切口或假体大小似乎对术后疼痛没有显著影响。有一个趋势是,与其他患者相比,酮咯酸和布比卡因组的患者在恢复室停留的时间更短,术后使用的镇痛药更少。没有需要再次手术的血肿,也没有并发症。术中局部给予酮咯酸和布比卡因加肾上腺素可显著减轻术后疼痛。
