Why does a Groschong catheter not require heparin?

Why does a Groschong catheter not require heparin?

• A. It has a shorter length
• B. It is used only temporarily
• C. There is a three-way pressure activated valve at the distal tip
• D. It is designed for less frequent use

Answer: (C)

A Groschong catheter incorporates a three-way pressure-activated valve at the distal tip that significantly reduces the need for heparinization. This mechanism allows for the prevention of blood reflux and the formation of clots in the catheter lumen without the routine use of anticoagulants like heparin. The valve system keeps the catheter's lumen free of blood while maintaining its patency, enabling secure access without the complications associated with anticoagulant use. Therefore, the unique design of the Groschong catheter directly contributes to its ability to function effectively without the need for heparin, ensuring safe and efficient vascular access for patients.
