I am curious how would a CRNA handle a case like this. Do CRNAs normally have higher threshold for canceling cases because they feel more obligated to listen to the surgeons? Would a CRNA agree to do MAC plus local anesthesia in this case? In a community private practice, how can a CRNA be expected to handle such a complicated case?
1. I would do this pt (very representative of the several thousand V.A. patients I've anesthetized) with a common-sense and gentle general anesthetic. No cookbook 2 ccs of X, 20 ccs of Y, 6 ccs of Z, but gently titrating everything to desired effect based on surgeon actions and estimated finishing time, constantly monitoring calculated MAP, and staying a step ahead of the surgeon at all times.
2. I always listen to surgeons. Part of OR etiquette is being a diplomat even when you wish to shout out loud something to the contrary. When they cross the obviously-ridiculous line, I politely say "sorry, wish I could, but I can't and here's why" -->> objective explanation given and 99.9% of the time accepted.
2a. If it's the pt's time to go, you can do the world's most perfect anesthetic and they'll still kick the bucket. On the other hand, if it's not yet their time, you can give the sorriest anesthetic ever and the pt will still sail through.
3. I wouldn't do this via MAC. Umm, no, sorry. Perhaps an LMA.
4. In private practice, a CRNA can be expected to handle this case as so eloquently said by Dr. Michael Bookallil, elder statesman on GASnet (run by Dr. Keith Ruskin at Yale): "GA,
if you know how." This case really isn't complicated. He's had his AAA and carotid stenosis repaired, and assuming his DM and other co-morbidities are under reasonable control and he can walk from the parking lot to the check-in desk without needing a wheelchair then why waste time and $$$$ for more work-up? You know what the IM consult will say:
a. avoid hypoxia
b. avoid hypotension
c. (my personal favorite) monitor BP interoperatively.
5. I trained at Charity Hospital in New Orleans. This case is a chip-shot compared to the pathology which sometimes came to those magnificient ORs.
