Subject: [ferrethealth] gas anesthesia and recovery
To: ferrethealth@yahoogroups.com
I just wanted to offer this info about gas anesthesia-part of why it is used is because it is easier for the body to expel it-they simply breathe it out of their system once it is discontinued, so they recover more quickly from it than with a lot of injectibles, etc.
Many times when a patient has a hard time recovering from anesthesia, they are actually having a harder time getting rid of the effects of premedications (i.e. ketamine, valium, etc for dogs, as an example) than with the actual gas (isofluorane in most of the cases I deal with, among others), especially patients with compromised livers or kidneys, as these organs are what typically metabolize most injectible forms of anesthesia. So patients having a tough recovery are not usually having a hard time expelling the gas anesthetic itself, unless they perhaps have some compromised lung or respiratory function.
Again,_ most_ problems/deaths, etc associated with surgery are not actually related to gas anesthesia itself (see my earlier posts re: risks of hypothermia, hypoxia postop, etc.).
Best,
