to aspirate or not while giving insulin and flu vaccines

Posted

I have been a nurse since 1974, and I went Thursday to get a flu vaccine at the health dept. and discovered the they did not aspirate when they gave the injection. When I questioned it they informed me, this was the new recommendation by cdc. They also said this applied when giving insulin. They told me the theory was , you did not receive all the vaccine when apirated. Now if cdc advises this, what happens if this vaccine is injected directly into a blood vessel.; and insulin what happens here. I know nursing is changing but I think this is risky.

I aspirate for all IM's, but not subcu's

Flu vaccines are given IM. I understand the subcu's. I just feel this is risky on IM injections.

I believe one of the major reason to aspirate is to ensure you are not into a major/minor vessle,thus making the injection an IV push injection...IVP insulin can be serious...the belly,back or the arms,flank are pretty safe for this reason,plus the insulin needle/syringe itself is basically too short to get into a vessel...I volunteered for a Meningitis scare years ago and gave hundreds in Im injections,all deltoid..and we all aspirated...my A and P is getting farther behind me,but some of us got pretty good back flow when we aspirated,so we tossed that needle and went to the other arm,and i if all was ok,aspirated again,and injected..

Here are some sources:

http://www.immunize.org/catg.d/p2021f.htm

"ACIP does not recommend aspiration when administering vaccines because no data exist to justify the need for this practice. Intramuscular injections are not given in areas where large vessels are present. Given the size of the needle and the angle at which you inject the vaccine, it is difficult to cannulate a vessel without rupturing it and even more difficult to actually deliver the vaccine intravenously. We are aware of no reports of a vaccine being administered intravenously and causing harm in the absence of aspiration. (10/05)"

From the CDC:

"Although certain vaccination specialists advocate aspiration

(i.e., the syringe plunger pulled back before injection),

no data exist to document the necessity for this procedure."

Hi, I am a nursing student and we are taught to aspirate when giving any IM injection, however we gave flu shots over at the health clinic and the instructions were not to aspirate. The reasoning was as stated above and also because the risk of going into a blood vessel when giving an IM into the deltoid is very minimal.

So, what's the harm of continuing to aspirate if that has been your practice? If they decide there's limited chance of an IV injection, fine, but aspirating causes no harm. I'd continue to do it.

I would rather someone aspirates when giving me an IM injection. This new changing data kinda scares me.

This is what I feel as well, but as a student I do what I am asked (as long as it is appropriate and within my scope) because I am working under another nurses license. Personally I would aspirate because it makes sense to do so and I like getting into the "habit" of doing things correctly because I am "new".

This sounds like a great topic for nursing research.

I do not aspirate when administering vaccines as per CDC recc., or SQ insulin.

That's interesting...I hit a vessel the other night with a SQ heparin shot in a belly. I pulled back and that sucker FILLED with blood - I got a nicer backflow that I usually get with an IV start, lol. I think I'm going to be aspirating my insulin injections despite the recommendation...I work with a nurse who got a backflow on an insulin shot in an arm about a year ago. Granted, the risk is small, and I doubt 2 units would be awful, but what about my out of control people who get 20? Or 30 of lantus? I don't think I'd want to give that IV. I think I'll have to check my policy...I've always aspirated. Hmmmmmm...

Interesting, they taught us to aspirate all except for heparin.:confused:

At my job all of us have heard and discussed the new CDC guidelines about not aspirating. All of the nurses so far have refused to stop aspirating. I have personally gotten blood back during aspiration (granted very rarely, but I was an injection nurse and did upwards of 50 to 100 injections a day at the time.) Not aspirating just doesn't feel like safe practice, no matter what the CDC is saying. By the way, please don't flame me, but at a conference I recently went to the CDC presenter stated that the new guidelines were released because of the worry that more and more MAs were giving injections and that the CDC is concerned about tissue damage from 'too forceful aspiration,' although I have never heard of or seen that before. He said that the risk of injection into a vessel was lower than the risk of tissue damage from aspiration. Now that is not my opinion, I work with MAs that could dance all over some nurses when giving injections. Just food for thought...they also said no more gluteal injections either, everything that went dorso-gluteal is now to go in the hip, ventral-gluteal.

I feel it's wrong not to aspirate. I wonder sometimes about B12 as it's red coloured anyway. Subq I have never aspirated for because this is how I was taught.

We were taught the same way. One of the nurses the other day in the nursery got a blood return giving vit. K. And I have heard some of the other nurses talking about getting blood return. I always aspirate. Would hate to give something IVP that wasn't meant to be no matter how small the risk.
