Pain control after total knee replacement (TKR) is pivotal in postoperative rehabilitation. Usage of epidural analgesia or parenteral opioids can cause undesirable side effects hampering early recovery and rehabilitation. These side effects can be avoided by infiltration of an analgesic cocktail locally. Our study was performed to evaluate the benefits of a particular cocktail combination in patients undergoing TKR with respect to pain and knee motion recovery.
One hundred consecutive patients who underwent simultaneous bilateral TKR were enrolled and received an intraoperative periarticular cocktail injection in the right knee (intervention) and normal saline in the left knee (control). Postoperative pain was recorded using the visual analog scale for each knee, and the time taken to achieve 90° of knee flexion was noted for each side.
The cocktail injected knee had significantly less pain when compared with the control knee during the first 48 hours and significantly shorter period to achieve 90° of knee flexion.
The use of intraoperative periarticular cocktail injection significantly reduces early postoperative pain and provides better early knee motion.
全膝关节置换术(TKR)后的疼痛控制在术后康复中至关重要。硬膜外镇痛或胃肠外使用阿片类药物会产生不良副作用,阻碍早期恢复和康复。通过局部注射镇痛合剂可避免这些副作用。我们开展这项研究以评估一种特定合剂组合对接受TKR的患者在疼痛和膝关节活动恢复方面的益处。
连续纳入100例接受同期双侧TKR的患者,右侧膝关节接受术中关节周围合剂注射(干预组),左侧膝关节注射生理盐水(对照组)。使用视觉模拟量表记录每个膝关节的术后疼痛情况,并记录每侧达到膝关节90°屈曲所需的时间。
在前48小时内,注射合剂的膝关节与对照膝关节相比疼痛明显减轻,达到膝关节90°屈曲的时间明显缩短。
术中关节周围注射合剂可显著减轻术后早期疼痛,并能使膝关节早期活动情况更佳。
