Local Infiltration Anesthesia Vs Femoral Nerve Block for TKA: A Meta-Analysis .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Analgesic efficacy of local infiltration anaesthesia versus femoral nerve block in alleviating postoperative wound pain following total knee arthroplasty: A systematic review and meta-analysis.
Br J Anaesth . 2016 May;116(5):597-609.Eight randomized controlled trials including a total of 454 patients undergoing total knee arthroplasty were included in this systematic review and meta-analysis comparing local infiltration anaesthesia (LIA) versus femoral nerve block (FNB). Pooled outcomes of interest included pain scores at rest and during movement, opioid consumption, and patient satisfaction. The results indicated no significant difference in resting and movement-related pain scores between LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The main findings suggest that while both LIA and FNB are effective for pain control, LIA offers the added benefit of reducing opioid use, making it a preferable choice for postoperative analgesia in knee replacement surgeries.
