what about a quinton cath? where does it end up? and a generic central line?
occasionally, a peripheral iv is started in an artery instead of a vein (by mistake, of course). when that happens, especially on a critical patient, why can't we give medication through it before discontinuing it?
medications can't be given into an arterial line because they (meds) can cause the artery to spasm. major tissue damage can occur. (this is especially true of the pulmonary artery. never give meds through the pulmonary artery port of a pa catheter).
i once saw a patient who had a line inadvertently started in the radial artery. demerol was given. patient lost his hand.
edited to answer the other part of the question:
any kind of central line should have its distal tip in one of three locations: the svc, inverior vena cava (ivc), or right atrium of the heart. if the tip stops short of there (say, the brachiocephalic vein [also called the "inominate vein"]), it is not technically
a central line.
(ra as a location is a little controversial except for hd catheters. it is generally an accepted location for hd cathters.)
so in general, central lines that start in the upper body (ij, subclavian), end in the svc or right atrium. central lines that start in the lower part of the body (fem lines) end in the ivc.
i did a whole inservice on this stuff. if anyone wants to look at it, and has power point, send me a pm and i'll send it to you.
