BP 53/35 on 3.5 dopamine. He's back to requiring his binky, so I spend a lot of time holding it for him.

The nice Resident that I forget the name of says they found that he had low cortisol levels after the surgery (apparently you normally create it in response to stress [like surgery], and it's common for cardiac patients to not do so) and that probably explains his low BP, so they're supplementing him with cortisone. They hope to step him down off of it once they've extubated him and he's no longer on dopamine. She might be talking about the same thing you heard about steroids. Not sure. They're still hoping to extubate today. . probably this afternoon.
