High-volume infiltration analgesia in bilateral hip arthroplasty

چکیده
BACKGROUND AND PURPOSE High-volume infiltration analgesia may be effective in postoperative pain management after hip arthroplasty but methodological problems prevent exact interpretation of previous studies. METHODS In a randomized, double-blind placebo-controlled trial in 12 patients undergoing bilateral total hip arthroplasty (THA) in a fast-track setting, saline or high-volume (170 mL) ropivacaine (0.2%) with epinephrine (1:100,000) was administered to the wound intraoperatively along with supplementary postoperative injections via an intraarticular epidural catheter. Oral analgesia was instituted preoperatively with a multimodal regimen (gabapentin, celecoxib, and acetaminophen). Pain was assessed repeatedly for 48 hours postoperatively, at rest and with 45° hip flexion. RESULTS Pain scores were low and similar between ropivacaine and saline administration. Median hospital stay was 4 (range 2-7) days. Interpretation Intraoperative high-volume infiltration with 0.2% ropivacaine with repeated intraarticular injections postoperatively may not give a clinically relevant analgesic effect in THA when combined with a multimodal oral analgesic regimen with gabapentin, celecoxib, and acetaminophen.

Ropivacaine plasma levels following local infiltration analgesia for primary total hip arthroplasty.
We measured total and free plasma concentrations of ropivacaine following high-volume, high-dose local infiltration analgesia in 19 patients aged 65 years or over undergoing unilateral total hip arthroplasty. The patients received 180 ml ropivacaine 0.2% (360 mg), which was injected into the deep and peri-capsular tissues, the gluteal muscles and fascia lata, and the subcutaneous tissues and sk...

BACKGROUND AND OBJECTIVES High-volume local infiltration analgesia (LIA) is widely applied as part of a multimodal pain management strategy in total hip arthroplasty (THA). However, methodological problems hinder the exact interpretation of previous trials, and the evidence for LIA in THA remains to be clarified. Therefore, we evaluated whether intraoperative high-volume LIA, in addition to a m...
متن کاملLocal Infiltration Analgesia for Postoperative Pain Control following Total Hip Arthroplasty: A Systematic Review
Local infiltration analgesia (LIA) is an analgesic technique that has gained popularity since it was first brought to widespread attention by Kerr and Kohan in 2008. The technique involves the infiltration of a large volume dilute solution of a long-acting local anesthetic agent, often with adjuvants (e.g., epinephrine, ketorolac, an opioid), throughout the wound at the time of surgery. The ana...

BACKGROUND We studied the efficacy of local infiltration analgesia in surgical wounds with 0.2% ropivacaine (50 mL), ketorolac (15 mg), and adrenaline (0.5 mg) compared with that of local infiltration analgesia combined with continuous infusion of 0.2% ropivacaine as a method of pain control after total hip arthroplasty. We hypothesized that as a component of multimodal analgesia, local infiltr...
