- Registration Number
- NCT06557018
- Lead Sponsor
- Dezhou Hospital Qilu Hospital of Shandong University
- Brief Summary
The goal of this clinical trial is to learn if drug Bupivacaine liposomes works better than traditional peri-articular injection for Control of Pain in Total Knee Arthroplasty. It will also learn about the safety of drug Bupivacaine liposomes.
The main questions it aims to answer are:
Does Bupivacaine liposomes works better than traditional peri-articular injection for Control of Pain in Total Knee Arthroplasty.
Researchers will compare Bupivacaine liposomes to traditional peri-articular injection to see if drug Bupivacaine liposomes works better for Control of Pain in Total Knee Arthroplasty
Participants will:
Receive peri-articular injection in total Knee Arthroplasty. checkups and tests During hospitalization.
- Detailed Description
Total knee replacement (TKA) has made significant progress in the treatment of chronic intractable joint pain, and now the fastest effective way to treat serious knee diseases is to perform artificial knee replacement (TKA). Pain is an important factor affecting patients' satisfaction with TKA surgery, and it is also a key factor affecting patients' postoperative rehabilitation and reducing surgical complications.
Effective analgesia program can not only improve the postoperative satisfaction of patients, reduce the use of analgesic drugs, reduce postoperative adverse reactions, but also shorten the length of hospitalization and reduce hospitalization costs. Local Infiltration Analgesia (LIA) is a simple and effective analgesia technique that involves the infiltration of drugs into the wound during surgery. The duration of the analgesic effect can be prolonged by precisely placing the catheter at the surgical site for further local anesthesia after surgery. The most commonly used drugs for intra-articular and extra-articular injections are morphine, steroids, clonidine, epinephrine, ketorolac, ropivacaine, and bupivacaine.
Bupivacaine liposomes, as a new formulation of long-acting sustained-release bupivacaine, are of great significance for multimodal analgesia after TKA. At present, there are no studies on the application of bupivacaine liposomes and knee replacement in China. The purpose of this study was to observe the analgesic effect and effect on function of bupivacaine liposome used in local infiltration analgesia after total knee replacement, and to explore its analgesic effectiveness and safety, so as to provide some reference for the selection of analgesia for total knee replacement.
