delayed effects of novocaine?

Question

In the last week, I've had two dental procedures and received a total of 8 shots total of novocaine (5 yesterday). I had a sudden increased heart rate and a sense of flushing right after the last shot that lasted 10 seconds. That evening (5-10 hours later), I had horrible pains in my sternum and back and stomach felt some difficulty breathing and I threw up several hours later. I felt better after that but low energy all day today. Does novocaine do this?

Answer 1

The RN above wasn't far off.

I can tell you it was most likely Lidocaine that was used.

Her (?) assessment that that was "too much" is kinda unreliable. you had five shots yesterday. I strictly doubt the dentist injected you with five CARPULES (at 1.8 mL each) of anesthetic. probably a little to start...then finished the carp. then used another in another area and then a little of another to back those up. so while you might have been injected 5 times, the amount you got is impossible to know. well, it shoudl be in your recrod, so you could ask.....

the increase in HR and flushing is because the local anesth. (soem of them) use epinephrine to help keep them in the area they're injected. epinephrine works like adreneline. if the dentist injects it and it goes directly into an artery, that's why you get that reaction.

Tell your dentist ...s/he should be aspirating the syringe before injecting all the way...this will tell if they're in the artery or not and thus avoid the reaction you had. it shoudl be avoidable.

as for the oter reactions you had, that' was probably just the result of stress and anxiety from the other stuff.

let me know if any other questions!

Novocaine Side Effects

Answer 4

To further add to the above:
1. The most commonly used local anaesthetic (LA) in dentistry is lidocaine with adrenaline.
2. Adrenaline IS epinephrine.
3. There have been no reports of true allergic reactions to lidocaine in all the years and millions (billions?) of injections given. However, allergies have linked been to OTHER ingredients (sodium metabisulfite, methyl paraben - no longer used).
4. For a 70kg person the max legal dose of 2% lido with epi in 1.8 ml cartridge would be 11 full cartridges in a single sitting. There have been cases of patients receiving more without side-effects.
5. The half-life of lido is 1 1/2 - 2 hours, so by 8 hours there will only be about 5% left.
6. If an LA with adr was injected into a VEIN, then you will get a transitory increase in heartbeat which can be uncomfortable. ARTERIES are much harder to penetrate, and if unlucky enough to hi one, then you will often get a very sharp pain as it goes into spasm, and part of your face will blanch. Neither accident is harmful.
7. Some people are generally more sensitive to LA with adr. Plain LAs are available but will wear off faster and have a lower max dose.
8. Your delayed reaction is due to the stress. Sometimes people also have queasy stomachs from painkillers they've been taking, often on empty stomachs.

You could be having an adverse reaction to the anesthetic. It is not novocaine, incidentally, that went out in the 1960's. It's more likely benzocaine or procaine, etc. Some people are hypersensitive to the drug. Make sure you tell your dentist about your adverse response and ask that he use a different anesthetic on you. You could also space your treatments out further apart to limit your dosing. The quantity you received for one procedure seems rather large too.
It is rare, but some people have died from drug hypersensitivity reactions from local anesthetics, so make sure your dentist is aware of your symptoms and take appropriate action. Otherwise I would recommend changing dentists.

My daughter had several teeth pulled this morning. Everything was fine until three hours later we went for ice cream, in line my daughter fainted. She come too and several minutes later went into a seizure. Her eyes rolled back in her head and she was pure white and her lips were blue.. I thought she died right in front of me. We had called 911 immediately and was rushed to the hospital. The hospital feels it had nothing to do with the dentist and feel it was not a real seizure.I feel I need more answers than she was dehydrated and a drop in blood pressure. Anybody ever had any experience like this. Any information would be helpful because I am worried sick!

Local dental anaesthetics contain adrenaline as it helps control bleeding, well the adult ones anyway.
