HICKMAN LINE Meaning and
Definition
-
A Hickman line, also known as a central venous catheter, is a device used to gain access to the central bloodstream for intravenous therapies, medications, or fluid administration. It is a long, flexible tube made of either silicone or polyurethane, equipped with multiple lumens to allow simultaneous administration of different medications or fluids.
A Hickman line is typically inserted in a surgical procedure under local anesthesia, where one end is placed in a large vein near the heart, such as the subclavian vein or jugular vein, while the other end remains external for easy access. The external part of the line has a cuff or a cap that helps secure it in place and prevent bloodstream infections.
The Hickman line is often used when patients require long-term intravenous therapies that cannot be effectively administered through regular peripheral veins. This may include chemotherapy, long-term antibiotic treatment, parenteral nutrition, or regular blood transfusions. The line allows healthcare professionals to deliver these treatments safely and efficiently while minimizing discomfort for the patient.
Maintenance of a Hickman line involves regular flushing with saline or heparin to prevent blockages and reduce infection risks. The line should be handled with strict aseptic technique to ensure its integrity and minimize the risk of introducing pathogens into the bloodstream.
Overall, a Hickman line is a crucial medical device that provides reliable central venous access for patients requiring long-term intravenous therapy, contributing to their improved health outcomes and quality of life.

Etymology of HICKMAN LINE
The word "Hickman line" is named after its inventor, Dr. Robert Hickman. Dr. Hickman was an American physician who developed this type of central venous catheter in the 1970s. The device was designed to provide long-term access to the veins for medical treatments such as chemotherapy, blood transfusion, or parenteral nutrition. As a tribute to Dr. Hickman's contributions, this central venous catheter became widely known as the "Hickman line", retaining his name as its identifier.
