HICKMAN CATHETER Meaning and
Definition
-
A Hickman catheter is a medical device used for long-term access to the bloodstream. It is a type of central venous catheter that is surgically inserted into a large vein, usually the jugular vein in the neck or the subclavian vein under the collarbone. The catheter is then tunneled under the skin to an exit site on the chest or abdomen.
The main purpose of a Hickman catheter is to provide a reliable and accessible way for healthcare professionals to administer medications, fluids, or blood products directly into the patient's bloodstream. It is particularly beneficial for individuals who require frequent or long-term intravenous therapy, such as those undergoing chemotherapy, requiring long-term antibiotic treatment, or in need of regular blood transfusions.
The catheter consists of two lumens, or tubes, which allow for separate infusion and withdrawal of fluids. One lumen is used for administration of medications and fluids, while the other allows for blood withdrawal or monitoring. This design eliminates the need for frequent needle sticks, enhancing patient comfort and limiting the chance of complications.
The Hickman catheter is typically made of silicone and is implanted under sterile conditions. It is securely sutured in place to prevent accidental dislodgement. Regular cleaning and dressing changes are necessary to prevent infection.
Overall, a Hickman catheter is a medical device that provides a safe and effective means for healthcare professionals to access the central venous system, allowing for the delivery of various treatments and therapies in patients requiring long-term intravenous access.
