    The study analyzed 774 patients undergoing ultrasound-guided peripheral nerve blocks for blast-related limb injuries.

  • 2

    The overall block failure rate was found to be 27.8% in patients with blast injuries.

  • 3

    Anatomical distortion was present in 64% of cases, significantly impacting block success.

  • 4

    Independent predictors of block failure included vascular reconstruction, large hematoma, and fracture displacement.

  • 5

    The study emphasizes the need to recognize trauma-specific anatomical predictors to optimize regional anesthesia strategies.
