298 Saudi Journal of Anesthesia / Volume 17 / Issue 2 / April-June 2023 Dear Sir, Peripheral venous cannulation (PVC) is a routine procedure in the perioperative setting, intensive care unit, and emergency departments. Large‐bore intravenous cannulas (16G, 18G) and peripherally inserted central lines (PICC) are most commonly inserted in the cephalic vein, basilic vein, or the great saphenous vein. However, these veins share intimate anatomical proximity with peripheral nerves and often show anatomical variations.[1] Peripheral nerve injury (PNI) is a reported complication of venous cannulation, frequently at the cubital fossa and other forearm locations, such as anatomical snuff box, wrist, and lower one‐third.[1,2] Surprisingly, PNIs following PVCs are less often reported in the literature than the actual incidences.[2] These injuries amount to considerable morbidity and bring forth long‐term impairment.[3] However, to date, no precise preventive strategy for their occurrence has been documented in the literature. The point‐of‐care ultrasonography (POCUS) has become an endorsed standard for central venous cannulation as it improves the success rate and minimizes the associated complications. POCUS can be a safety tool for preventing PNI during PVC/PICC, at high‐risk anatomical locations.
