A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein . A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.
Patient specific risk factors for the development of catheter-related bloodstream infections include placing or maintaining a central catheter in those who are immunocompromised, neutropenic, malnourished, have severe burns, have a body mass index greater than 40 (obesity) or if a person has a prolonged hospital stay before catheter insertion.

Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.Similar to the Hickman line, the tip of the catheter is in the superior vena cava, and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body.

Peel-off sheath was then inserted over the guidewire. Blood is aspirated from the catheter to confirm the position. Then, the free-end of the port catheter is inserted through the peel-off sheath. After the tip of the port catheter is confirmed at the aortocaval junction, the peel-off sheath is taken-off by peeling away with two hands.
A small needle is inserted into a blood vessel, then exchanged for a catheter over a wire. The catheter is directed at the vessel to be studied, and contrast is directly injected to evaluate the lumen under video X-ray. This is an older technique than modern CT angiography or MR angiography, but provides unique advantages. With a catheter in ...
No study has definitively demonstrated improved outcome in critically ill patients managed with PA catheters. [4] [5] Given that the PA catheter is a monitoring tool and not a therapy in and of itself this is not entirely surprising. Justification for its continued use rests on a large body of clinical experience, disadvantages of other cardiac ...
