This document provides information on inserting tunneled dialysis catheters. It discusses the preferred insertion sites being the right internal jugular vein. Potential acute complications during insertion include arterial puncture, pneumothorax, hemothorax, and air embolism. Subacute complications after insertion include suboptimal flow due to malposition, kinking, clots or fibrin sheath formation. Tunnel tract infection is also discussed as a complication requiring antibiotic treatment and catheter removal. The document provides guidance on preventing and managing these potential complications.
