A Hickman line is an
intravenous catheter most often used for the administration of
chemotherapy or other medications, as well as for the withdrawal of blood for analysis. Some types of Hickman lines are used mainly for the purpose of
apheresis or
dialysis. Hickman lines may remain in place for extended periods and are used when long-term intravenous access is needed.
