Clinical Trial Summary

To study the effectiveness of ACB and iPACK block with liposomal bupivacaine for postoperative analgesia in patients undergoing knee arthroplasty


Clinical Trial Description

The pain after knee arthroplasty limits the patient's activities and postoperative recovery, and currently there are mainly three analgesic methods: intravenous analgesia, epidural analgesia and nerve block analgesia. There is a lack of studies on whether liposomal bupivacaine, if used for ACB and iPACK block, can achieve benefits in knee arthroplasty pain management by prolonging sensory nerve block without affecting muscle strength, improving patient prognosis, and shortening hospitalization days. In this study, in order to better evaluate the effect of liposomal bupivacaine for ACB and iPACK biock on the prognosis of patients undergoing knee arthroplasty, not only the NRS and AUC of patients in each group will be observed, but also the postoperative QoR-15 Quality of Recovery Rating Scale, postoperative nausea, vomiting and other complications, and the number of hospitalization days will be also included as observation indicators. The completion of this study can provide a clinical basis for the selection of analgesic regimens for knee arthroplasty, and also provide strong evidence-based medical support for the relevant medical decision making of government departments. ;
