For all the talk about regurg/asp, in my experience I've only seen 4 patient types actually regurge /vomit dangerous volumes of poisonous gastric fluid or contents: Those on parenteral narcotics on the ward for any length of time, those on the ward in a debilitated state, those with an acute bowel obstruction, pediatric patients who lie or are poor historians (I exclude drunks, L and D and trauma as separate, non-elective categories). While I still observe conventional wisdom with regard to diabetics and the obese, Ive yet to see one regurge around an ETT during an elective, fasted case.

I doubt I'll ever change, as discretion is the better part of valor, but I surely do RSI's (let alone intubate) far more often than I need to.
