A Day in the OR

Learner promise

By the end of this module you should be able to name the main people in an operating room, follow a surgical case from pre-op to PACU, and know how to conduct yourself as a student.

Who this is for: students about to start time in the OR. Not for: instruction on performing any clinical task. Watch, ask, and follow your team.

Why this matters

The OR has its own geography, hierarchy, and rules. Students who understand the room before they walk in spend less energy feeling lost and more energy actually learning.

The room, in two zones

Before you worry about anyone's name, learn the room's geography. The operating table sits in the center. The anesthesia machine and workspace are at the head of the bed. The scrub tech's instrument table sits along one side, and the back table with extra sterile supplies at the foot. Everything draped in blue or green is sterile territory - everything else is where you can exist.

The OR roles map

• Surgeon - performs the operation; leads the surgical plan.
• Surgical assistant / resident - assists at the field.
• Anesthesiologist - manages the patient's physiology; usually at the head of the bed.
• CRNA / AA - delivers anesthesia care with the anesthesiologist.
• Circulating nurse - the "circulator" moves around the room (not scrubbed in), gets supplies, documents, and keeps the room running.
• Scrub tech / scrub nurse - sterile; manages instruments at the field.
• Perfusionist - runs the heart-lung bypass machine in cardiac cases (not in most cases).

The case timeline

1. Pre-op - patient interviewed, consented, IV placed, monitors applied.
2. Induction - anesthesia begins; the airway is secured. The room goes quiet and focused - stay engaged, pay attention, and be respectful of the people doing their jobs.
3. Positioning and prep - patient positioned, surgical site sterilely prepped and draped.
4. Maintenance - the operation proceeds; anesthesia keeps the patient stable. Your best learning time: questions are welcome all day, but this is when there is actually time to answer them.
5. Emergence - anesthesia is lightened and the patient wakes.
6. PACU - the patient recovers under nursing and anesthesia oversight.

Your first morning

• [ ] Arrive early; find the OR board and your room.
• [ ] Change into hospital scrubs, hat and mask where required.
• [ ] Introduce yourself by name and role.
• [ ] Ask the anesthesia team where to stand.
• [ ] Look for small ways to be useful - help move the patient, grab a warm blanket when someone asks.

One-page student etiquette checklist

• [ ] Introduce yourself to the team, including the circulating nurse and anesthesiologist.
• [ ] Ask the anesthesia team where to stand before you move.
• [ ] Never touch anything blue/green or draped - that is the sterile field.
• [ ] Keep your hands above your waist and away from the field once you are near it.
• [ ] Phone away and silenced.
• [ ] Do not lean on the patient, the bed, or equipment.
• [ ] During induction and emergence, stay engaged and give the team room to work.
• [ ] If you feel faint, step back and tell someone - do not be a hero.

Day-one pro tip

During induction, stand where you can see both the monitor and the airway. Same event, two views - you'll learn twice as fast.

Reflection prompt

What is one thing about the OR that felt less intimidating after learning the roles and timeline?

Faculty discussion prompt

Ask the circulating nurse: "What do students most often get wrong in their first week?"
