Can you give blood and antibiotics both at the same time through a triple lumen cath?

Yes, you can via different ports. However, I wouldn't give the first dose of a new antibiotic at the same time as blood as you would have difficulties determining the source of any potential reactions.

I'm also a nursing student, but this is what they taught us in our central line lab.

I agree.

I agree also. Good point about monitoring for a reaction.

Blood moves through the body rather quickly, the heart pumps 60 to 100 beats per minute, over a gallon a minute. So use those lumens, that's what they are there for.

It is done all the time. I agree about starting a new med or first dose of an antibiotic when starting the blood because if there is a reaction you won't know if it's the blood or the med that is causing it and would have to at least temporarily stop both.

ditto

Agree about giving new med and blood at the same time; otherwise, yes-you can give antibiotics and blood at the same time through a triple lumen.

That is why they are placed!

If there is going to be a blood transfusion reaction, it will most likely be within the first 15 minutes of the transfusion. Given that information, you could always wait 30 min to an hour after starting the blood before you give the abx. If it is a new abx and the patient has never had it before, then I might wait a little longer, unless your hospital has a policy against it. Check that out. If not, then just use your nursing judgement. You also want to make sure you're not giving the person too much fluids at once and putting them into fluid overload.... That most likely wouldn't happen because the patient is already anemic anyway. But you have to consider everything.

You can give blood and AB through different lumens of the central line at the same time. However a CVC is not the most appropriate way of delivering blood because its long and skinny. Not sure I agree to wait regarding new AB with the first dose because the reaction is likely to be the subsequent dose as the patient will need to be sensitised. Unless of course they have had the same class of drugs and developed a sensitivity. It will be all muddled up anyway.

My rule is always to give AB on time because of the need to ensure an appropriate blood level to ensure organisms are killed off. So I guess I would need to understand the context for individual patients and make sure it fitted them.

A CVC's lumen isn't any smaller than a peripheral IVs and is in many cases wider. For instance, the distal ports are 16 gauge at my hospital. It is long, of course, but there's nothing contraindicating usage of a CVC for blood administration.

Regarding allergy formation, you'd go slow with the first dose precisely because they'd be sensitized to it in the past. Even if were a new antigen, there wouldn't be much of a problem with the second dose as your body doesn't turn around and make antibodies that fast. Now, third or later doses, sure, which is why we must always be vigilant.
