Is a fast heartbeat common after using an anesthetic spray?

Question

Hello doctor,

It was over two weeks ago that I had my endoscopy. I was not sedated, but they gave me a local anesthetic spray. However, after my endoscopy, I feel like my heart is beating faster than normal. I also feel like my nerves or muscles are twitching or throbbing. I went to a doctor, who said I do not have toxicity, but I got so curious if I actually have toxicity. So is it? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

Local anesthesia toxicity can happen if the spray is used at high concentrations. Usually, they will have 10 percent Lignocaine spray. They can spray a maximum of 300 mg of the drug. But for your procedure, they definitely would have used less, so do not worry.

The other symptoms you had are because of your anxiety, stress because you are not sedated and you are just given local anesthesia. If toxicity happens, first, you will have fits (seizures, numbness over the lips and around the mouth).

I hope that you get your answer.

Please let me know if you need any help.

Thank you.
