Those are some pretty arrogant words. Get off your high horse.
Extubation criteria in the OR is not the same as in the ICU.
In the ICU there is an acceptance that a certain number of patients will be re-intubated. If you don't end up re-intubating some you aren't being aggressive enough in your weaning strategy. That's acceptable, considering that the patient population as a whole is different: often unable to perform mental status examination, following commands, etc. You extubate based on meeting parameters (RSBI, NIF, labs, ventilating/oxygenating/protecting airway/etc...) and gestalt. You balance the risk of aggressive weaning strategy with the potential harm in keeping a patient intubated for a long period of time (progressive weakness, pneumonia, trach, etc). In the OR, we often have more than just these parameters. We often want the patient to be following commands, purposeful actions, sometimes doing math before we extubate. Sometimes if we're not happy we bring them to the PACU intubated to chill out a bit, let the anesthetic wear off further, and we reassess. We don't have the luxury of having the patient sit in the OR for hours until they are extubated. Having to re-intubate someone after coming out from the OR is not seen with the same degree of acceptance.
