A silastic venous catheter may beused by Radiology personnel to inject contrast media. True or False?

Answer 1

it MAY be used

True

such venous catheters come in various sizes such as the small cannula used for peripheral vein injection and the long catheters used for angiography ... classically to inject contrast material

(I must say that I don't like the term "contrast media" because I feel it is a little unclear in the context of an exam - strictly the medium is the environ in which the information is stored rather than a dye or other material used to provide contrast - they should use "contrast material" or "dye" or gadolinium or whatever you want to use but be more specific).

In the radiology setting mentioned by the above poster practices will vary from hospital to hospital. In many institutions the plastic cannula will be placed in the vein rather than using the needle for the injection of contrast.

Answer 2

Radiology when doing a test with contrast medium will insert a small needle into your hand which is connected to a small gauge catheter for the delivery of the medium. The cath itself is not inserted.

Answer 3

i say false because the silastic caths we use are very small bore and the high pressure injections performed in radiology may fracture the catheter
