Abstract

Intrafascicular injection represents one of the most serious complications in regional anaesthesia, potentially resulting in irreversible neurological injury. Despite the advances in ultrasound-guided techniques, inadvertent intraneural and intrafascicular injections still occur. This review synthesizes the current understanding of nerve microanatomy, mechanisms of nerve injury, and the diagnostic and preventive strategies aimed at avoiding this catastrophic event. It highlights the role of ultrasound technology, echogenic needle innovations, injection pressure monitoring, neurostimulation, and emerging applications of artificial intelligence in enhancing procedural safety. The integration of these multimodal safety tools can significantly reduce operator dependency and improve real-time feedback during nerve block procedures. With continued technological refinement, structured training, and incorporation of AI-assisted imaging and robotics, the risk of intrafascicular injection can be minimized, thereby improving patient safety and outcomes in regional anaesthesia.
Keywords: Intrafascicular injection, Regional anaesthesia safety, Ultrasound guidance, Echogenic needles, Pressure monitoring, Artificial intelligence.
