Cauterize – Fire to heal wounds? 😮

Question

In a scene from The Blacklist, one of the characters uses a lighter on a wound to “cauterize” it. It looks painful but works. What exactly is it and is it actually done in medical scenarios?

Answer 1

Cauterising doesn’t heal wounds it just burns it so it stops bleeding, in general it’s a bad idea since you are actually creating more injuries but in some edge scenarios it’s neccesary so you don’t die from blood loss
