Long story, semi short. 60 some yr old guy with a hx of cabg x 2 and chole admitted for syncopal episodes at an OSH. Patient was over there for a month runs into aki requiring dialysis and cvvh. Kidneys recover, liver fails - ercp x 2. Pt trached and finally sent to us for further management. Was sedated with Ativan up until 1 day before tx, trached and receiving tpn. Guy has intermittent runs of vtach, send full of labs. Troponin = 6.40, who knows if it was even checked at the OSH. They weren't checking his ammonia levels. Initially on norepinephrine at 10, sicu wants vaso and wean norepinephrine... I leave him w vaso on and Levo at 6. What is the pressor of choice for a troponin and guy requiring pressors for maps > 60???
