Hi:

What is the most potent topical anesthetic?

Hi:

I've heard that extreme pain causes neurogenic shock by overexciting the parasympathetic nervous system. This causes the heart rate to slow too much leading to a dangerous drop in blood pressure and, hence, shock -- maybe even death.

Does severe pain cause this type of shock?


Thanks,

Hi:

Burn victims must undergo a painful debridement of their wounds in order to prevent infection. Normally, they are given morphine and other non-anesthetic pain-killers. Sadly, this does not work. They still yell in pain during the operation, which is why they have to be housed seperately from other patients.

Why aren't the burn patients given anesthesia [local or general] prior to the operation? Is there a safety issue with anesthetics?


Thanks,

Green
