Cannulation of the subclavian vein

Insertion of Subclavian Catheter

The junction of the medial 1/3 and lateral 2/3 between clavicle and first rib with direction towards opposite shoulder is infiltrated with local anesthetic agent after preparing it with a cleansing agent.

The needle is inserted in to the punctured site and directed towards the suprasternal notch.

When blood is noticed in the needle coming freely into the syringe, syringe is removed and cannula is inserted in the subclavian vein.

The needle is subsequently withdrawn and cannula either locked or attached to IV drip. The cannula is anchored to the skin.

A dressing is then placed over the insertion site.
