Understanding the Differences Between Peripheral and Central IV Cannulas: Insights from Suzhou Texnet

Intravenous (IV) cannulation is a fundamental procedure in medical practice, enabling the administration of fluids, medications, and nutritional support directly into the bloodstream. There are two primary types of IV cannulas: peripheral and central. While both serve the purpose of vascular access, they differ significantly in their placement, usage, risks, and clinical applications.

Placement and Anatomy
Peripheral IV Cannulas are inserted into small peripheral veins, typically located in the hands, forearms, or sometimes the feet. These veins are superficial and easier to access. The cannula tip resides in the peripheral vein itself, providing access to the peripheral circulation.

Central IV Cannulas (or central venous catheters) are inserted into larger, deeper veins near the heart. Common insertion sites include the internal jugular vein in the neck, the subclavian vein under the collarbone, or the femoral vein in the groin. The tip of a central cannula resides in a large central vein, usually the superior vena cava or the right atrium of the heart, allowing direct access to central circulation.

Size, Length, and Clinical Uses
Peripheral IV Cannulas are generally shorter and smaller in diameter, suitable for short-term therapies such as fluid replacement and medication administration. In contrast, central cannulas are longer and designed for long-term use or delivery of irritant medications like chemotherapy or vasopressors. Suzhou Texnet’s product range caters to both types, ensuring healthcare providers can access reliable, certified supplies tailored to diverse clinical needs.

Insertion Procedure and Risks
Peripheral cannulation is simpler and less invasive, often performed by trained nurses, while central venous cannulation is more complex, requiring specialized skills and ultrasound guidance. Central lines carry higher risks such as pneumothorax, thrombosis, and infection. Suzhou Texnet’s stringent quality control team ensures all products meet rigorous international standards to minimize these risks and support safe clinical outcomes.

Duration and Maintenance
Peripheral cannulas are recommended for short-term use (usually 3 to 4 days), whereas central lines may remain in place for weeks or months. Proper maintenance and timely replacement are critical to preventing complications. Suzhou Texnet’s commitment to quality and customer service helps healthcare institutions worldwide maintain safe and effective IV access.
