When at the Dentist earlier, I was asked if I wanted to numb gum for small filling. I said I would. After injection, I felt very agitated, my heart was beating very fast. I asked Dentist to wait a couple of minutes because of these feelings. She e explained that's because of the adrenaline that's in the local anaesthetic. Apparently, it comes in different strengths. I never knew this before. I explained I was on bete blockers for a fast heart beat already! So next time she will use anaesthetic without adrenaline. Did any of you know/ experienc this?
Adrenaline with a local anaesthetic in a patient on beta Blockers is not a problem.
Adrenaline is a vasoconstrictor (narrows blood vessels) and when given with a local anaesthetic, deters the anaesthetic from departing from the site of injection and hence prolongs the period of anaesthesia.
Patsy...fairly new.....perhaps 50 years old.;-)
As a medical student in the 1950's all local injections were given with adrenaline....for the reasons i have given.
Sqad, shouldn't you also be told "and you may feel your heart racing" if this is the case? It's a discombobulating feeling but nobody would worry if they'd been warned.
Sqad, it was the same with me as with Patsy, I only ever had it happen once despite my gums being a pincushion from how many injections I've had. I can't say I like them but they don't start my heart racing with fear.
It's not a matter of knowing the contents of the injection but of being prepared for possible side-effects. Is there any other likely explanation apart from adrenaline?
