Pain after total knee arthroplasty is severe and impacts functional recovery.
We performed a retrospective study, comparing conventional patient control analgesia (PCA) modalities versus continuous femoral nerve blockade (CFNB) for 1582 post-TKA (total knee arthroplasty) patients.
Using our electronic acute pain service (APS) database, we reviewed the data of 579 patients who had received CFNBs compared with 1003 patients with intravenous PCA over 4 years.
Our results show that the incidence of a severe pain episode was higher in the PCA compared with the CFNB group. Lower pain scores were observed in the CFNB group compared with the PCA group from postoperative day (POD) 1 to 3, primarily due to lower rest pain scores in the CFNB group.
Our study shows that there is improvement in pain scores, at rest and on movement, as well as a reduction in incidence of severe pain, in patients who receive CFNB versus those who receive intravenous PCA.
全膝关节置换术后疼痛剧烈，影响功能恢复。
我们进行了一项回顾性研究，比较1582例全膝关节置换术（TKA）后患者采用传统患者自控镇痛（PCA）模式与持续股神经阻滞（CFNB）的效果。
利用我们的电子急性疼痛服务（APS）数据库，回顾了4年间579例接受CFNB患者的数据，并与1003例接受静脉PCA患者的数据进行比较。
我们的结果显示，PCA组严重疼痛发作的发生率高于CFNB组。与PCA组相比，CFNB组在术后第1天至第3天的疼痛评分更低，主要原因是CFNB组的静息疼痛评分更低。
我们的研究表明，与接受静脉PCA的患者相比，接受CFNB的患者在静息和活动时的疼痛评分均有所改善，严重疼痛的发生率也有所降低。
