We can speak in generalities and anecdotes all day long. I have seen cardiac anesthesia make some very questionable decisions for instance i have seen them push phenylephrine in someone with bad cold and wet decompensated heart failure who just came back. We spent the rest of the day trying to keep this guy alive. This year I have seen anesthesia kill 2 of our AI patients with precedex alone. Cardiac anesthesia consults us (cardiology) all the time fo management of complex cardiac patients (in "their" cardiac surgery ICU).
What can I say? Giving precedex to an AI patient (optimally kept at a high HR and low MAP) is risky, because it can induce an atropine-resistant bradycardia. It's rare, but it can happen. Same thing about a decompensated CHF: one doesn't want to increase afterload on that guy with phenylephrine. Let's not speak about what it does to a possible pulmonary hypertension.
In both cases, what matters the most is not what they gave, but how much and how fast. Slowly titrating that precedex, and even the phenylephrine, with an A-line in place, allows for turnaround space if things start going south. Also, many times people are very sensitive to certain drugs, so even that is not enough. Had I been there, I would have asked them why they chose that specific drug and dose.
By the way, where I trained, the interventional cardiology stuff, like most off-floor anesthesia, was reserved for weaker anesthesiologists (except for pedi), for two reasons: 1. it is considered mostly straightforward, beyond induction and emergence; 2. there is a cardiologist there who knows how to fix a cardiac emergency better. The really good anesthesiologists did not spend much time off-floor, so we are probably talking about different levels of professionals.
Of course there are exceptions to all rules but, as a rule, I tend to trust our badasses more in an emergent situation, because you only see the 2-3-5 bad outcomes, but I see the many times when they avoid them. When a patient survives a surgery, especially a sick one, it's usually not because everything went so smoothly that nothing needed to be done, but because the anesthesiologist worked hard behind the curtains to adjust for every little change, to prevent crashes. No offense, but the average doctor, even the average surgeon, has no idea what it takes to take some patients through general anesthesia and real surgery. It's friggin' induced coma. Some of the really sick patients are so fragile they can be killed just with a vial of propofol.
I doubt that the cardiac surgery ICU people will call you in an emergency to save one of their patients. Of course they will consult you for the non-emergent management of their patients; any good intensivist would. A good doc actually knows where her knowledge ends, so it's much more shameful
not to ask for help.
You can pound your chest all day about how good anesthesia is about taking care of a crashing patient but it is more of a skill to prevent a patient from crashing than bringing them back from their crash.
I read not 2-3, but many more than 20-30 absolutely dumb preop assessments/year, coming from cardiologists who must have zero idea about what happens in the OR and what the real surgical/anesthetic risk is for a certain procedure, or that certain procedures have an unacceptable chance of turning into general anesthesia.
And if we are generalizing anyway, I still have to meet an interventional cardiologist who induces respect by not being cocky and know-it-all.
