It is usually placed by a catheter (tube).
[12] [23] [1] This is a one-step approach which does not require the removal of MNs and is convenient for long-term therapy. [12] [21] However, incomplete insertion and delay dissolution is observed with the use of dissolving MNs. [21] This polymer would allow the drug to be delivered into the skin and could be broken down once inside the body.
Arthroscopic surgery. Minimally invasive procedures were pioneered by interventional radiologists who had first introduced angioplasty and the catheter-delivered stent.Many other minimally invasive procedures have followed where images of all parts of the body can be obtained and used to direct interventional instruments by way of catheters (needles and fine tubes), so that many conditions ...
Doses which would require more than 2 mL to be injected at once are not administered subcutaneously. [11] Medications which may cause necrosis or otherwise be damaging or irritating to tissues should also not be administered subcutaneously. [12] An injection should not be given at a specific site if there is inflammation or skin damage in the area.
Specific types of long-term central lines are the Hickman catheters, which require clamps to make sure that the valve is closed, and Groshong catheters, which have a valve that opens as fluid is withdrawn or infused and remains closed when not in use. Hickman lines also have a "cuff" under the skin, to prevent bacterial migration.
