I am resident, CA-2, so limited experience.
Five pedi hearts and 30 adult hearts are in my belt.
In pedi hearts, the lines are more difficult. They have better neuro status and no carotid disease so the chance of post-operative stroke is less.
Overall, they are both very cookie cutter...Sleep then lines then pump then inotropic support then ICU.
One thing is very funny. The congenital heart guys like to come off on Dopamine for support. The dopamine is at low, should not do anything doses..like 3-5 mcg.kg.min. However, when you turn it off, the CO goes to SH**. Maybe the textbooks are right about everything.
They also like nitroprusside for decreasing afterload. This boggles my mind. I really like Nicardipene. They both work, but the nicardipene seems to be safer and easier to use.
At my institution, the adult guys like epi for inotropy.
