What must be done prior to the first use of a nontunneled percutaneous central catheter?

Confirming placement by X-ray is essential prior to the first use of a nontunneled percutaneous central catheter because it ensures that the catheter tip is situated correctly within the central venous system. Proper placement is crucial to prevent complications such as puncturing the pleura or incorrect placement into a smaller vein, which can lead to improper medication delivery or even more serious complications like pneumothorax or embolism. An X-ray provides a visual confirmation that the catheter is in the ideal position for administering IV fluids, medications, or drawing blood. Prior verification of placement establishes safety and efficacy in the use of the catheter, making it a critical step before any therapeutic interventions can occur.
