Intraoperative Infiltration of Liposomal Bupivacaine vs Bupivacaine Hydrochloride for Pain Management in Primary Total Hip Arthroplasty: A Prospective Randomized Trial.
Pain management after total hip arthroplasty is well studied. Nevertheless, there is no consensus regarding the "cocktail" to use in periarticular infiltration (PAI). Liposomal bupivacaine (LB) is a slow release local anesthetic that can be infiltrated during surgery. In this study, we compared LB to bupivacaine hydrochloride (HCL).
