Does lidocaine (numbing) cream interfere near blood draw results or IV?
The child has a medical condition and has to come into the hospital once a year or so. She has a lidocaine prescription for insulin pump site change, to make them less painful.
If she have to come in to the ER, is there anything wrong with putting rather where they'd be likely to draw blood from, or insert an IV? It's not necessary logically, but it'd spare her the pain. She's 6.
Citing a source/experience would be helpful. Or, if you're giving an educated guess, that's okay too, simply say so.
Answers:
I don't see any harm in placing the lidocaine cream around 5-10 min before the the IV start or blood draw. That would give the cream some time to absorb. The nurse or phlebotomist will alcohol the nouns where they would like to stick 1st to decrease infection likelihood. Source(s): I am a nurse
EMLA cream will numb the skin, but you have to put it on for a good 45 minutes ahead of time, with an occlusive dressing (like Tegaderm). It also make the skin a little thick and doughy, which can make it harder to start the iv or draw blood.
Other than that, it's without a flaw acceptable. Source(s): I'm an anesthesiologist. Sometimes we use this for IV starts.
Hi Mozz. My guess (barely educated within this matter, I am only a CNA and can just speak from personal experience) would be that at hand is nothing wrong with that, as it is being used as it be intended- to prevent/minimize pain in a small area. My apprehension is that the cream would be contraindicated if the area needing numbing was significant, or a more effective anesthetic is needed. Last summer my son opened up the back of his commander on our entertainment center and the lidocaine cream was applied 45 minutes before they used surgical staples to close the laceration. It worked wonderfully. I would check with the hospital though, for ours routinely give a lidocaine shot before inserting an IV, but not for blood draws. Of course, if you had applied the cream you could just deny the anesthetic if an IV is needed. I googled use of the cream for those procedures and every cite I read in relation to children indicated its use before starting an IV being effective contained by minimizing pain (the child will feel pressure) and actually helping the procedure to travel faster. I did not come across information stating it would interfere with either the application of the procedures or the results of blood draws. Take care :).
No, using lidocaine cream does not interfere with any routine laboratory test, nor does it upset the giving of iv drugs or fluids. I see no reason against using it surrounded by this context. Source(s): 20 years intensive care medicine
Back when I was in medical university, there was a clinic for children with HIV and they'd routinely come surrounded by with a prescription numbing cream (lidocaine w/ prilocaine) topical anesthetic cream covering the site where blood would be drawn for routine IV blood draws so I can tell you from first mitt experience that this was a common practice for those young children who be terribly scared or uncomfortable beside blood draws.
Although I can't give you a citation off hand that it's okay to do, I can a moment ago assure you from my clinical experience back when I was a medical student in the 90s that it be perfectly fine to use such a cream (Emla) for just such children and it never interfered with IV blood draws (there's no point for it to).
