Before the Patient Goes to the OR

Cut to the Chase: General Surgery Survival Series — Post 16

The call came at 6:47 in the morning. A PGY-1 had done everything right the night before. Examined the patient, written a clean note, told the senior the plan. The case was on the board for 8 a.m.

By 7:30, anesthesia was asking whether anyone had checked the INR. The patient was on warfarin for a valve. The note mentioned it once, in the problem list, and never again.

The INR was 2.6. The case got bumped. The attending wasn’t furious. He was something worse. He was unsurprised.

The problem isn’t that trainees forget things. It’s that nobody’s told them what “before the OR” actually means.

Pre-op looks like documentation. Labs ordered, consent signed, NPO written. It’s actually a thinking task wearing documentation’s clothes.

Nobody’s checking that you filled the boxes. They’re checking that someone stood in front of this patient and thought it through.

You’re not scanning the chart for normal. You’re scanning for actionable. The creatinine that was 0.9 in clinic and is 1.9 today. The pressure of 172/98 nobody commented on. The baby aspirin she mentioned this morning that the team nodded past.

The case is won or lost before anyone scrubs. The hour in holding is where you find the landmine, not the OR.

So stop thinking about the operation and start thinking about the person on the table. The pre-op question isn’t “does she have the disease” — you know she does, that’s why she’s here. It’s whether she can survive the fix and recover from it.

A gallbladder is a gallbladder. A gallbladder in an 82-year-old on a blood thinner with an ejection fraction of 30% is a different operation entirely — and that difference got decided in clinic, not on the table.

The best read on whether she’ll tolerate it isn’t buried in a panel you ordered. It’s whether she can climb two flights of stairs without stopping. So ask her.

Then there’s the morning-of machinery, and your job is to assume none of it actually happened.

The consent, the marked site, the NPO status, the allergy band — every one of them got “confirmed” by someone who assumed someone else checked first. Be the someone who actually looked.

NPO after midnight isn’t hospital tradition. It’s airway math. A patient who ate breakfast at 5 for an 8 o’clock case isn’t a scheduling problem — she’s an aspiration risk the second she’s induced.

Anesthesia counts hours, not meals: roughly six after a meal, two after clear liquids.

“She just had a little toast” is the sentence that cancels the case.

Then there are the medications, where the quiet disasters live — and where a student who knows the list cold becomes the most useful person in the room.

Was the warfarin stopped on schedule, the DOAC timed to her kidneys, and did someone confirm it rather than assume it?

If a blood thinner shows up anywhere in the chart and there’s no plan written beside it — held, bridged, reversed — assume the plan doesn’t exist yet. The INR you ordered and never read cancels more cases than the one you forgot.

The pre-op antibiotic has to be in within sixty minutes of incision. Before the cut; after doesn’t count. If you’re the one watching that clock, you’re already more useful than you feel.

A medication list without “held, continued, modified” next to each item is a list. Not a pre-op note.

A patient can be cleared for surgery and not ready for surgery on the same morning. Cleared is a consultant’s opinion from weeks ago. Ready is whether anything has changed since then — and someone actually checked.

Here’s the instinct that separates you from the attending: yours is momentum. The case is on the board, so the case is happening. The attending is running the opposite question the whole time — what would make me stop?

Sometimes the right call is not to operate today. The trainee already asking that question is the one I stop worrying about.

Before every case, I do the same thing. I walk up to the patient in holding — not the chart, the patient — and I look.

Is she breathing harder than yesterday? Does she look more sick than she did on rounds? The chart tells me what was true at midnight. The patient tells me what’s true right now.

And usually the only person in scrubs who sat with her this morning, who knows what she’s actually afraid of, is the student who pre-rounded at 5 a.m.

That isn’t a small job. That’s the job.

So when the time-out starts, stop moving and listen. Name, procedure, side, allergies, antibiotics, blood. If something said out loud doesn’t match what you know to be true, say so — even if you’re the most junior person in the room. Especially then.

Wrong-site surgery is supposed to be impossible now, precisely because no one’s allowed to skip this. Newcomers catch the errors experienced people automate past.

Ready doesn’t mean the paperwork is done. It means nothing is about to go wrong that you could have caught while she could still tell you.

The Pre-Op Basics — before, and the morning of

When you're not sure what to order, start here. This isn't the whole workup — it's the floor for most operations, the part you default to before you tailor it to the patient in front of you. It splits by timing: what gets handled before the day of surgery, and what gets confirmed the morning of.

Before the day of surgery

• History and physical — current, and actually examined, not copied forward

• CBC — baseline hemoglobin and platelets, especially when blood loss is expected

• Basic or comprehensive metabolic panel — electrolytes, renal function, glucose

• Coagulation studies (PT/INR, PTT) — if they're anticoagulated, has liver disease, or a spinal is planned

• Type and screen — crossmatch when real blood loss is expected; it has a short shelf life, so mind the timing

• Pregnancy test — anyone who could be pregnant

• Hemoglobin A1c — in diabetics, to know what you're working with

• ECG — by age, cardiac risk, and procedure risk; not on everyone

• Chest imaging or PFTs — only when symptoms or the operation earn it

• Relevant imaging (CT, US) — obtained and available, not scrambled for the morning of

• Cardiac risk and functional capacity — plus any specialty clearance the patient actually needs

• Consent — the conversation had, the form signed, matching the planned operation

• Anticoagulation plan — when to hold, whether to bridge — decided in advance

• Medication and NPO instructions — given to the patient before they leave

The morning of surgery

• NPO status — confirmed with real times, not assumed

• Consent — signed, and still matching the operation planned

• Site mark — placed by the surgeon before she goes back

• Allergies — confirmed and banded

• Home meds — what was actually taken or held: anticoagulation held, insulin adjusted, beta-blocker continued, steroid stress dose if she needs one

• Morning glucose — in diabetics

• Antibiotic prophylaxis — ordered and timed to within sixty minutes of incision

• VTE prophylaxis — started as planned

• IV access — adequate for the case

• Anything that changed overnight — new labs, new vitals, new complaints

• The time-out — name, procedure, side, allergies, antibiotics, blood
