An overnight surgical consult gets settled at the bedside, not on the phone. A surgeon with twenty years of night call on what to ask the Emergency Medicine physician, how to examine a patient in a hallway with dignity, why you check both groins on every obstructed patient, and how to write a note that still holds up at six in the morning.

You read all twenty-six charts at home last night. At six the attending will ask what happened overnight, and most of your answer will be decisions your intern made about patients you know only on paper.

An intern asked me once how long you're supposed to listen. A full minute was the easy half of her question. The other half was how long she was allowed to stay in the room.

An intern stopped me in a stairwell in November and asked how long a person stays this tired. Being tired doesn’t take what you know. It takes the walk back down the hall to somebody you already decided about, and you won’t feel it go.

Report what happened, and stop. Everything else is a forecast, and forecasts are not yours yet. What to say when an operation goes wrong.

You have a thought that is sixty percent built, and by the time you are sure enough to say it out loud, somebody else has already said it. An attending on why the window where your observation is worth something is the window where you are still unsure, and how to say "I'm not sure yet" in a shape the team can actually use: name what bothers you, what you would do next, and what would change your mind.

A liter of fluid will raise almost anyone's blood pressure for a while, which is exactly the problem with it. An attending's walkthrough of postoperative hypotension: how to tell a real number from a cuff artifact, what perfusion looks like under your hand, why the bolus is a test rather than a gesture, and what a transient responder is telling you.

A senior told me the ICU is just the floor with more numbers. He was half right. They are the same numbers, but up here somebody is paying for every one of them.
