Infraclavicular brachial plexus block for the management of inadvertent intraarterial drug administration after arterial insertion of a venous cannula during ultrasound-guided venous cannulation.

This case report documents the inadvertent placement of an arterial cannula despite using realtime ultrasound to insert a peripheral venous cannula in a child with difficult venous access. The resultant limb ischemia was treated with an infraclavicular ultrasound-guided brachial plexus block as sympatholytic treatment.
