Why use epinephrine with lidocaine

Common Questions and Answers about Why use epinephrine with lidocaine

epipen

I have to go have a tooth filled tomorrow and I'm somewhat apprehensive about the anesthetic. I know most often the ones they use contain epinephrine because it's a vasoconstricter and causes the anesthesia to work longer. I know you can request the anesthetic without the epi but then it wears off quickly (like when they are drilling on your tooth). I asked my cardiologist and he said if I didn't get a big dose of the epi, if it was mixed, with the beta blockers I should be ok.
I had to get stitches last night, and was given 5-6 shots of epinephrine and lidocane. I told the intake nurse I was taking synthroid (which I presume implies thyroid problems). I felt a little "unusual" afterward (pounding heart, feeling calm and detached..), and was googling the side effects of the shot.. an article said this: "Additionally, epinephrine and lidocaine usually aren’t used in patients with thyroid disease, or disease of the kidneys or liver.
It probably isn't the lidocaine, it's the epinephrine that is in the lidocaine. You can ask your dentist to use an anesthetic without epinephrine, I have had tons of dental work and always ask for that. Dentist doesn't mind at all and I've never had any problems. It doesn't last as long but if you start to feel anything while they are working the dentist will just give you more. I have done fine with it.
The amount is so small that I have never heard of it causing tachycardia, although this is theoretically possible. Lidocaine and epinephrine is used in the suturing of millions of wounds every year with no cardiac events. My guess is that that is a coincidence here. The temporary fast heart rate in the absence of chest pain, pressure or other symptoms should have no long-lasting effects whatsoever. An EKG will verify that because tissue death is reflected in an abnormal ST segment.
the actual anesthetic (which ends in -caine, e. g. lidocaine) and epinephrine. All standard local anaesthetics contain the preservative sodium bisulfite or metabisulfite. The preservative is necessary to keep the epinephrine fresh (epi quickly deteriorates and becomes useless otherwise). The standard local anesthetic cartridges (called lidocaine in the U.S. and lignocaine in the U.K.) have epi added". http://www.dentalfearcentral.org/allergy_novacaine.
You can have your dentist use an anesthetic that does not contain epinephrine to rule out any possibility of these complications. For example, carbocaine 3% without epi. I use it every day on heart patients. It is perfectly safe if you are not allergic to it. The most common anesthetic, lidocaine, typically has a very small amount of epi in it to help the anesthetic last longer and to help minimize bleeding.
I had a tooth pulled, they used epinephrine. I was in afib with low rate for 8 days. Then afib every 2-3 day. I was given Rythmol as PIP. I gradually have had less afib, but, each one has 100 for rate...I called dr. and asked him what to do....he said I needed ablation and bp monitors were not accurate. I got a new dr. and new dr. did not say anything about the lowered rate. I go to new EP next week. I will ask him.
A-fib can be managed with medication if ablation is not an option or is not successful. I'm not sure why they would require you to retire on disability. I have friends with a-fib that are still working. One is in his 70's, still working part time. As for tachy bursts, I've had them all my life, given birth to 3 kids and raised them (talk about stress) and worked with wildlife for 21 years now. Does my heart kick up into tachy? Yeah but I wait it out if I have to. Don't give up just yet.
Also, not saying you do, but illegal drug use can be major problem for people with normal hearts, rhythm wise, but with someone with a known arrhythmia, engaging in illegal drug use is asking for major problems. Also, when I go to the dentist, since I have an arrhythmia, I always ask that they use a local anesthetic (like Novocain) without Epinephrine, which is related to adrenaline. Epinephrine helps to sustain the anesthetic, but can cause heart rhythm problems.
the actual anesthetic e. g. lidocaine and epinephrine. Most people who have a genuine allergic reaction to local anesthetics are not allergic to the actual anesthetic agent. It is much more common (though still rare) to be allergic to preservatives in the local anesthetic solution. So, an allergy specialist may be able to help identify the allergen and desensitize you. Hope this helped and do keep us posted.
I remember becoming so ill with the same symptoms as a youngster and young adult until I was able to insist that the dentist use non-epinephrine anesthetic ( lidocaine) . I didn't know what was wrong with me, but knew something in the "shot" at the dentist's made me sick. OF course, I had other "spells" but my reaction to epinephrine was clearly important.
) I'm glad I initially used the incorrect term of 'Novacaine' in my search, because after reading all of this and going back out of curiosity and searching again, substituting the word 'Lidocaine' for 'Novacaine', this page didn't come up! (The links I did get with 'Lidocaine' were much more technical and generally did not include web discussions.) So thanks for the correction of terminology; it's good to know two anesthesia words for related searches.
Artificial sweeteners? Exposure to organic solvents? Chronic cutaneous exposure to solutions containing lidocaine and epinephrine? Which of the following can be triggers and should be avoided?
The dentist said they would use no epinephrine. Will that help? I am very nervous about having this done while pregnant - I also have exercise induced PVC's. Any advice you can give will be appreciated. I love this forum!!!! Thanks, Karen.
In preparation for the sentinel node procedure, I had the radioactive tracer injected in 4 shots around my nipple, while in nuclear medicine. The radiologist said that he would be drawing up lidocaine with each injection but there might be a slight feeling of pain. It was painless and all I felt was a little pressure. I am a scientist and I guess I mentally put on that hat while they were taking the pictures to see if the tracer had found my sentinel node.
Ask them next time to use only lidocaine without the epinephrine. Thermography is again being studied, but currently is not useful. I certainly wouldn't trust anyone offering thermography except in a research setting. One of the (many) big problems with thermography is that it creates problems that it cannot solve.
One word of caution though, for any of the procedures, is to make sure the doctor doesn't use any anesthetic that contains epinephrine first. Even the smallest amount of that stuff can set me off for days and alot of the stuff they inject comes mixed with Lidocaine or they inject some before the actual product. I opted for the surfuce numbing gel (it's like Orajel) beforehand and did fine. I don't know if you've tried it, but I also love and recommend micro-dermabrasion.
Its just that auto immune does cause problems with local and deep anesthesia, its more to do with the epinephrine..... Will you let us know how she is later. Thinking so much about you all. Big hugs.
Now, 3 months before the dx of MS, it reappeared in the form of severe dysplasia and I had a leep proceedure, I had an extremely bad reaction to the lidocaine/epinephrine during that proceedure, blood pressure went sky high, rigid shaking of arms, head and tongue and face went numb, also on hte right side.
I believe the RN here quotes 50-75% of Birad 4 biopsies are benign, but my surgeon told me about 75% are benign. For a stereotactic biopsy they use mammogram (or some use a similar proceedure with ultrasound) to find the area to biopsy. They make a 1/4 inch incision for the needle which I understand can point different directions to take numerous samples. Very, very thin slices of tissue are removed using a vacuum type suction.
