High-volume infiltration analgesia in bilateral hip arthroplasty: A randomized, double-blind placebo-controlled trial
Acta Orthop. 2011 Aug;82(4):423-6. Epub 2011 Jul 1312 patients undergoing bilateral total hip arthroplasty (THA) were randomized to receive a high-volume infiltration of analgesia, administered intraoperatively to one hip, and a placebo saline solution to the other hip. Patients also received a pre-operative oral multimodal analgesic regimen. The primary outcome was postoperative pain. Results indicated that the high-volume analgesic intervention may not produce a clinically relevant analgesic effect post-operatively in patients undergoing bilateral THA compared to the saline group. These results indicate that a pre-operative oral multimodal analgesic regimen may provide sufficient pain relief for THA.
