Venous catheterization is a common medical procedure that provides direct access to a vein for medications, fluids, blood draws, or hemodynamic monitoring. It is essential for patients needing long-term intravenous therapy, critical care, or complex medical treatments. Timely and properly performed catheterization improves treatment effectiveness and patient comfort.
Why Venous Access Matters?
Reliable venous access is crucial for delivering life-saving medications, intravenous fluids, chemotherapy, or nutrition. Improper access can lead to complications such as infections, thrombosis, or vein injury. Expert catheter placement ensures safety, accuracy, and long-term vein preservation.
What is Venous Catheterization?
Venous catheterization involves inserting a thin, flexible tube (catheter) into a vein to facilitate treatment. Types of venous catheters include peripheral IVs, central venous catheters (CVCs), peripherally inserted central catheters (PICCs), and tunneled or implanted ports.
Types of Venous Catheters
- Peripheral IV Catheter: Short-term access for medications and fluids.
- Central Venous Catheter (CVC): Long-term access for medications, blood draws, or dialysis.
- Peripherally Inserted Central Catheter (PICC): Extended therapy through a peripheral vein with central access.
- Implanted Port: Surgically placed under the skin for intermittent long-term therapy.

- Preparation: Skin sterilization and local anesthesia are applied.
- Insertion: Catheter placed using sterile technique, with imaging for central lines or PICCs.
- Securing & Dressing: Catheter secured with sterile dressing to prevent movement and infection.
- Monitoring: Check for correct placement, blood flow, and signs of complications.
Management and Aftercare
