When I trained I was taught that OPCAGB was only for the healthy hearts like Sevo said. When I got to PP I was surprised to see that we chose the most sickly of hearts for OP as well. Actually, the only time we went on pump was for valves and the occasion crumpling pt that isn't tolerating the OP procedure which was pretty rare. Things got much less hemodynamically challenging when the cardiac stabilizer changed from the suction type to the type without suction ( don't know the actual name of it).
My approach was Aline, Swan, lg IV. Start a Lido drip and give some Mg. Syringe cowboy the rest. Usually used neo throughout the case as needed from a syringe. Occasionally needed NTG bumps but if that occurred I usually just started a drip as it would most likely be needed. Probably went to ICU on a dobutamine drip 80% of the time. Dobutamine was usually weaned off over the next 6-12 hrs. Pt extubated within 6 hrs but a few would be extubated in the OR.
In my opinion, these are much more fun that the pump cases. On a good day, we would do 3 in a room before 5pm. At least one would be sick as ****.
