Lin X, Zhou Y, Zheng H, et al. - Given that the lack of knowledge about continuous femoral nerve block (CFNB) and patient-controlled analgesia (PCA) among total knee arthroplasty (TKA) patients and their families often leads to an inappropriate dose of medications and increased workload for ward nurses, researchers examined if preoperative CFNB education could improve postoperative analgesic efficacy and could reduce the PCA-related workload for ward nurses after TKA. They randomly divided 60 patients undergoing unilateral TKA into groups A and B (n = 30 each). A nurse-led preoperative visit the day before surgery focusing on PCA educational pamphlets for postoperative pain management was made among patients in group B and their families. Face-to-face PCA pump operation training was provided to patients and their families in both groups before returning to the ward. Patients in group B had significantly lower Visual Analogue Scale scores at both rest and during movement than those in group A on postoperative days 1 and 2. Outcomes support the potential of enhanced preoperative education for CFNB with PCA in providing patients with a better grasp of postoperative pain management, improving the postoperative analgesic effect after TKA, and reducing the PCA-related workload for ward nurses.
