Efficacy of Fascia Iliaca Block Versus Intraoperative Nerve Infiltration During Anterior Hip Replacement Surgery
Completed · Not applicable
Conditions studied: Pain, Postoperative
In brief
Surgical trauma causes nerve sensitization leading to amplification and prolongation of postoperative pain. In experimental studies, pre-injury neural blockade using local anesthetics has been shown to reduce post-injury sensitization of the central nervous system, while similar techniques applied after the injury had less or no effect (FILOS). Investigators have therefore designed this study to examine the timing of FICB (pre-operatively versus intra-operatively) on postoperative pain in patients undergoing anterior hip replacement surgery.
