When injecting lidocaine as a local anaesthetic, it's really rather important that you don't give too much, what with the whole making-the-nerves-stop-working aspects of its pharmacological profile.
When given locally it's a terrific anaesthetic, however if too much is allowed into the general circulation, everything gets a bit tingly, the brain goes a tad bezerk and heart decides to stop cooperating. In essence, don't give too much.
So how much to give?
Well on it's own, Lidocaine doses shouldn't exceed 3mg/kg however when given with adrenaline, to induce vasoconstriction and thus limit systemic spread, the dose can be increased to 7mg/kg.
How to remember this?
Syllables!

ReplyDeleteI definitely shouldn't put lidocaine on my manly digit either, right?
ReplyDeleteprobably best not, obviously depending on what you're going to be using it for
