lidocaine and action potential

Threshold is point at which you generate an action potential...below it there is no response and anything above it produces a response. The response is "all-or-none", that is an action potential is what is generated. If I remember my physiology and understand your question... a delay in reaching threshold will increase the time in-between the action potentials generated thereby reducing their frequency. Hope this make sense.

what really is cardiac action potential and how does it work with potassium to lower the heart rate?

Yes you may be right about that. And I think this question may describe an unusual situation or application of the concepts. It is one thing to answer the question wrong on the exam; another to have to make a hard decision in real life without supportive, expert guidance. I wonder which it is here. According to wiki, a person in hemodynamically unstable VT should be cardioverted before receiving amiodarone.

left pointer finger, at work i stuck a cedar sliver under the nail past the start point of the nail. I attempted to pull it out and it broke off. only 1/4 inch came out so a good 1/2 inch is still in there i can see it thru the nail. I attempted to cut and split the nail with razor blade but once i got part way thru nail it hurt bad. my co-worker gave me a new 10ml bottle of lidocaine, he uses it to give himself stitches.

I feel you got relief as per the basic mechanism of these medicines. The action of steroids is that it is anti-inflammatory in nature and relieves pain to its action. The action of lidocaine is that it is a local anesthetic hence it prolongs the action of any drug when administered together. Keep me informed if you have any queries. Bye.

One is Lidocaine 2 % Gel, Marccain, Kenalog and Heprin. The second is 1% Injectable Lidocaine, Sodium Bicarbonate and they add your Elmiron. I've had both extensively and found them to be a tremendous help. You'll need to see a doctor in The Urology Group. Some of the doctors are better with IC than others, read their bios on their website and look for one the mentions female urology not prostrate surgery. Here's the URL to their website http://www.theurologygroup.cc/index.asp.

s the geek in me, wondering if there is a connection between injection and/or body fighting off potential infection.

last year before the holidays (about 3 monhts ago) I recieved unprotected oral sex and protected sex with a CSW, I didnt have any syntomps so I didnt test. Recently I felt very guilty and decided to take a urine test for Gonorrhea and Clamidya, this was negative but I read on your posts about Gonorrhea clearing up at the mens system in about 6 weeks, my questions are, 1)Is it possible for me to have aqcuired gonorrhea and not develop any syntomps and have infected my wife?

ve already described it in previous posts, and other users said that there a was a little risk. 3 months passed and two red spots appeared on my leg. I've read some hiv+ people's description of first manifestations, and I have the same thing: red spots on my extremities. Plus I have some kind of little round formations appeared just near the foundation of my tongue; i can not see them, but i feel them when I touch them by my tongue.

My dentist gives me my shot and see another patient, by the time he got back to me I was fully numb. and the numbness last for 8 - 12 hours. I am highly allergic to lidocaine it puts me into anaphylactic shock, I have an epipen but sa that I don't have to use that I just make sure everyone is doing their job and I always wear my medic alert bracelet.

The doctor prescribed Prednisone, Valtrex, and Lidocaine they all help but none are stopping the evening pain making it very hard to sleep.

How can we stop itching? I had a yeast infection and now my boyfriend has it to bc of me...

These findings might include a markedly prolonged action potential Also, there may be a greater amplitude in the action potential. This procedure may be painful for some people and less so for others. The muscles tested may be sore for days after the test. ************************************************* Te Evoked Potentials have nothing at all to do with the muscles, for general discussion. At the bottom I will describe a MOTOR evoked potential that is sometimes performed.

i got a handjob from a busy and dirty hooker. i wore a condom on the penis but there was a cut on back side of the penis. did i get hiv? please answer asap i am freaking out. im terribly scared!! please note that the 'cut' on back side of my penis is has not been bleeding,i can see the skin beneath the cut,its like an inner layering. please tell me if its sufficient for hiv virus to flow in my bloodstream.i can send u a snapshot if u want.

So I have really bad vaginismus to the point where intercourse can only be done with a lot of lidocaine and with the help of dilators. I am 15 weeks pregnant and concerned about delivery. Will my vaginismus prevent me from vaginal delivery? Is anyone else dealing with or has dealt with this??

Previious Dx Bursitis R) shoulder.My doctor has ordered R) shoulder U/S and X-ray. Query disease or Occupational wear and tear? Thankyou for any suggestions.

I take it at night before bed (at least two hours after dinner) as it seems to help with getting up in the morning. I recently started taking melatonin and I am now having hot flashes. I had these initially when I first started taking thyroid (I think it had more to do with my metabolism and heat regulation actually working or trying to work right). I was wondering if melatonin needs to be taken one hour or four hours after my thyroid pill.

The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses. When the polar opposites cathode (negative electrons) and anode (positive electrons) reach a specific level there will be repolarization by transfering electrons from anode to the cathode.

ve had quite a few stellate ganglion blocks and have had some success. They thought the lidocaine infusion might help the other pain I deal with and kill two (or more) birds at the same time so to speak. KittKat23-78, Sorry the infusion didn't help you!! I hadn't heard about having several a few days apart; I'll have to ask about it. Mine is (at least one) being paid for by worker's comp. I'm hopeful but also trying to keep things realistic and in perspective.

Hey. I went to my PCP yesterday and he gave me a LIDODERM, a lidocaine patch, to try and help with the pain in my neck -he thinks if that calms down so will the migraines.. theyve been everyday constantly for well over a month and a half, and no meds help.. nor do therapeutic methods i have here at home.. Has anyone here used it before? And did it help? I tried to use it last night but it wouldnt stick to my neck.

Has anyone ever been prescribed this for genital outbreaks or PHN? My doctor did for PHN. I just tried it for the first time it hurt to apply and doesn't feel the most pleasant now. Has anyone ever used this and what was your experience?

I did something with someone 9 days ago that I had just met and now I am worried about my potential risks. After much kissing I put my finger in his anus while he masturbated-and to the best of my knowledge there were no cuts or nicks on my finger. What is my potential risk for being infected with HIV if he was positive? Also, if there were cuts/nicks I could not see would that increase my risk. Thanks for your time.

They reduced but are still present. I tried on the other bra and managed to wear it for a few hours. My entire cup area was burning. Now I read about all the issues with VC. My bras are not from VC. Rather from a local small canadian town merchant. Thus she won't take them back. The frustration is you spend good money, and you don't know what to expect. It has the potential to harm these small town merchants.

As I am not a doctor, I can't tell you. The viral meningitis is not related to HIV and is coincidental. It's "potential" herpes, you don't even know if you have it! I can't comment about herpes, I don't know much about it. Sorry :( When a condom fails, it fails catastrophically! (Just check posts by Lizzie Lou and Joggen, they know their stuff!) You would have known if it failed. You are not at risk for HIV.

But since I had such severe heart reaction to just a shot of lidocaine at dentist in the past, the cardiologist said I am lucky I didnt go into cardiac arrest at that time and if they put lidocaine in me again he said my heart may suddenly fail (sudden cardiac arrest) and it may not be able to recover next time. And the warnings on lidocaine (even for people w/out heart problems) are such things as: rare but possible arrhythmias and cardiac arrest.

I am a 25 year old female and I had a seizure while having dental work done about 3 weeks ago. I had been given lidocaine and nitrous oxide. Following the appointment, I went to a neurologist and had a CT scan and an MRI done. Both showed no brain abnormalities. I had eclampsia 4 years ago and had seizures which resulted in the early delivery of my child. Aside from my seizures 4 years ago, I had no previous history of seizure disorder.
