Liposomal Bupivacaine vs Perineural Adjuvants in Adductor Canal and iPACK Blocks in Patients Undergoing Primary Total Knee Arthroplasty
Wake Forest University Health Sciences
Summary
The purpose of this research study is to compare two different combinations of anesthetic medications to see which works the best in providing the longest lasting pain relief for total knee arthroplasty surgery. The drugs being used are liposomal bupivacaine compared to a combination of bupivacaine, clonidine, epinephrine, buprenorphine, and dexamethasone. Pain scores will be collected at different intervals during study participation.
Description
This double-blinded prospective randomized control trial will evaluate analgesia following total knee arthroplasty for patients who receive an adductor canal block and infiltration between the popliteal artery and condyles of the knee (iPACK) block utilizing bupivacaine with the adjuvants clonidine, epinephrine, buprenorphine and dexamethasone (BPV-CEBD), as compared to patients who receive liposomal bupivacaine (LB) for both blocks. All patients will receive a spinal anesthetic with ropivacaine (17.5 mg) and fentanyl (10 mcg), and an adductor canal and iPACK block for analgesia. Patients ran…
