Dr Cantor? ? on local anesthesia.

[Guest guest]

Dr Cantor, Thanks for the explanation of what is in lidocaine.

My mother cannot have the normal lidocaine with epinephrine because

it puts her into anaphalactic (sp?) shock. Her old dentist had said

that it was the epinephrine she was apparently allergic to, but her

new dentist told her that that could not be because epinephrine is a

natural component of the body. He told her that her allergy was due

to the preservative used in the solution. She can have lidocaine

without the epinephrine without a problem.

She has the exact same reaction to even slight amounts of heparin on

the tip of an IV. Do you know if Heparin uses the same preservative

as Novocaine?

I have had local anesthesia dozens of times and never once had a

problem with it until my dentist injected it directly into a vein

that was right next to a nerve he was aiming for. I had the same

reaction my mother had. When I met with the anesthesiologist that

was to do handle my anesthesia for major surgery, I told him about

that scary reaction I had to the local anesthesia. He said that that

was a normal reaction to having epinephrine fed directly to the

heart (via the vein). Does that sound plausible?

I don't know if sulfites are used in heparin. Perhaps your pharmacist can look

this up. As far as your reaction to local anesthetic goes, the

anesthesiologist's explanation seems " plausible " to me, but to get more

authoritative information I would see an allergist.
