why can't you infuse glucose into a peripheral arterial line?
i should know this, i know. i've tried to google it and can't figure it out. does it mess up the bp reading?
well, i don't do babies......but i do
know iv therapy.
assuming that babies are the same as adults in this respect (and i don't know why they wouldn't be):
it is very dangerous to administer any
medication through an arterial line.
arteries have a thick layer of muscle, and are prone to spasms.
foreign substances, such as medications, tend to cause those arteries to spasm. this can lead to an infarct (tissue death) to the distal tissues.
there are some
medications that are safe (or relativly safe) to infuse into an artery. dilute heparin is one of them. some forms of chemo are also administered intra-arterially (ia), though there may be a risk-benefit trade off here. contrast and ntg are also given ia in the cath lab, though in this case, and spasm would most likely be noticed by the cardiologist.
so anyway, it is a safety issue. i know of patients that died due to meds infused via the pulmonary artery port of a pulmonary artery catheter (swan line) due to a pulmonary artery spasm that infarcted a lung.
