title: Recent advances in incorporation of local analgesics in postsurgical pain pathways.
abstract: Total knee and hip replacement surgeries are highly invasive, and a significant level of postoperative pain is commonplace in patients undergoing these procedures. It is now known that postoperative pain can affect hospital stay, patient satisfaction, postsurgical rehabilitation, and a range of other clinical and administrative outcomes. The need for a multimodal approach to the control of postoperative pain, using combinations of agents that have synergistic effects, is now widely accepted. There has been increasing interest in local periarticular and intra-articular injections, which can result in significantly less pain in the postanesthesiology care unit (PACU), significantly less use of rescue opioids in the PACU, significantly less confusion, significantly less blood loss, and a significantly lower bleeding index. EXPAREL® (bupivacaine liposome injectable suspension) is an extended-release anesthetic that is approved by the US Food and Drug Administration for single-dose injection into the surgical site to produce postsurgical analgesia. Several phase 2 and phase 3 studies across a range of surgical procedures have demonstrated that the inclusion of EXPAREL® in the multimodal regimen can significantly reduce both pain scores (including cumulative pain scores at 24 hours) and opioid consumption, as well as resulting in delayed time to the first use of opioids and more opioid-free patients at 72 hours. Multimodal regimens that include EXPAREL® may have important benefits in total joint arthroplasty.
