OR Etiquette: What Every New Medical Device Rep Needs to Know

The operating room is not a showroom. It is a controlled clinical environment where a patient is under anesthesia, a surgical team is performing a procedure that carries real risk, and every person in the room exists to serve one purpose: safe, successful surgery. You are a guest in that room. Your continued access depends entirely on whether the surgical team considers you an asset or a liability.

Every year, new medical device reps walk into their first OR and make mistakes that damage their credibility, disrupt the surgical workflow, or — in the worst cases — compromise the sterile field and jeopardize patient safety. Some of these mistakes are recoverable. Some are not. A rep who contaminates a sterile tray, touches something they should not touch, or says something inappropriate within earshot of an anesthetized patient can lose OR privileges at that facility permanently. No second chance. No appeal.

This guide covers everything a new medical device rep needs to know about operating room etiquette — from what to wear and where to stand, to how to interact with surgeons, nurses, and techs during a live case. It is based on how ORs actually operate, not how they look in training videos.

Before You Enter the OR

Your OR experience begins long before you walk through the doors. Preparation is the difference between a rep who adds value and one who creates problems.

Facility Credentialing

Every hospital and surgical center requires vendor credentialing before you can access the OR. This typically involves:

• Registration with a credentialing service (RepTrax, Vendormate/GHX, or the facility’s internal system)
• Proof of current immunizations (Hepatitis B, Tdap, annual flu vaccine, COVID vaccination per facility policy)
• TB test results (within the past 12 months)
• Background check
• HIPAA training certification
• Bloodborne pathogen training
• Facility-specific orientation or training modules
• Proof of professional liability insurance

Do not show up at a facility for the first time expecting to walk into the OR that day. Credentialing takes days to weeks. Start the process well before your first scheduled case. If your credentials lapse — expired TB test, expired training module — you will be turned away at the door, and your surgeon will be waiting in the OR wondering where their rep is.

Case Preparation

Before every case, you should know:

• The procedure being performed and the surgeon’s planned approach
• The patient’s relevant anatomy (imaging, templating, sizing estimates)
• Which implants and instrumentation the surgeon will need, including backup sizes
• The instrument tray setup and assembly sequence
• Any special equipment or supplies required
• The facility’s specific protocols for your product category

Arriving at a case without knowing the surgical plan is like showing up to a client presentation without knowing what the client does. It signals that you are not serious about your role, and the surgical team will notice immediately. If you are new to medical device sales, build a pre-case checklist and use it every time until the preparation is automatic.

Arriving at the Facility

Arrive early. Not on time — early. For a 7:30 AM first case, you should be at the facility by 6:00-6:30 AM to check in, change into scrubs, verify that your trays and implants have arrived and been processed, and be available for the surgeon’s pre-case briefing. Rushing into the OR five minutes before incision is a sign that you do not respect the team’s time or the seriousness of what they are about to do.

Check in at the front desk or vendor check-in station. Sign the vendor log. Display your badge visibly at all times. Know where the locker room is, where to change, and where to store your personal belongings. Do not bring unnecessary items into the surgical suite.

Attire and PPE Requirements

OR attire is not optional, not flexible, and not subject to your personal preferences. Every facility has dress code policies for the surgical suite, and you follow them exactly.

Standard Requirements

• Scrubs. Facility-provided scrubs, changed into at the facility. Do not wear scrubs from home or from another facility. Some facilities allow vendor-provided scrubs in specific colors; most require you to use the facility’s scrub dispensers. Scrubs should fit properly — not too tight, not dragging on the floor.
• Surgical cap or bouffant. All hair must be covered. This includes facial hair — if you have a beard, you need a beard cover. Hair should not be visible below the cap.
• Mask. Required in the OR at all times once the sterile field is open. The mask must cover both your nose and mouth completely. If you wear glasses, learn to position the mask so it does not fog your lenses constantly. A mask worn below the nose is worse than no mask — it signals you do not take infection control seriously.
• Shoe covers or dedicated OR shoes. Facilities vary on this. Some require disposable shoe covers over your shoes. Some require dedicated OR shoes (clogs or closed-toe shoes) that do not leave the surgical suite. Know the policy before your first case.
• Eye protection. Required during cases with splash risk (which includes most orthopedic procedures involving power tools, irrigation, or open surgical sites). Safety glasses, goggles, or a face shield. Prescription glasses alone do not count — they lack side protection.
• Lead apron and thyroid shield. Required if fluoroscopy or X-ray will be used during the case. In orthopedics and spine, this is frequent. Lead is heavy and hot. Get used to it. Make sure the lead fits properly and does not restrict your movement. If you are covering cases regularly, consider investing in a lighter-weight lead apron — your back will thank you.

What Not to Wear

• No jewelry below the elbows (rings, watches, bracelets) — even if you are not scrubbed in
• No artificial nails or nail polish (infection control policy at most facilities)
• No cologne or perfume — the patient is in a confined space under anesthesia, and strong scents can cause nausea
• No personal clothing visible outside scrubs

Understanding the Sterile Field

The sterile field is the most critical concept in OR etiquette. Violating it is the fastest way to end your career in the operating room.

The sterile field is the area around the surgical site and the back table that has been sterilized and must remain free of contamination. It includes:

• The draped patient from the level of the surgical site
• The back table and Mayo stand where sterile instruments and implants are laid out
• The area between the back table and the surgical site
• Any sterile-gowned, sterile-gloved team member (surgeon, assistant, scrub tech)

Rules You Must Follow

If you are not scrubbed in, do not touch anything in the sterile field. This is not a suggestion. Do not reach over a sterile table. Do not hand anything directly to a scrubbed team member. Do not brush against a sterile gown. If the surgeon asks you for an implant, you open the outer packaging and present it to the scrub tech, who takes the inner sterile package onto the sterile field. You never cross that boundary yourself unless you are scrubbed.

Maintain distance. Stay at least 12 inches from any sterile surface or sterile-gowned person. In a crowded OR, this requires constant spatial awareness. If you need to move past the back table, go around — not between the table and the surgical field.

Face the sterile field when passing. If you must pass near a sterile area, face it. Never turn your back to a sterile surface you are passing close to, because you cannot see if you are about to brush against it.

If you contaminate something, say so immediately. If you accidentally touch a sterile drape, bump the back table, or drop something onto the sterile field, tell the scrub tech immediately. Do not hope nobody noticed. They noticed. Trying to hide a contamination breach is orders of magnitude worse than admitting one. The scrub tech can re-drape, re-sterilize, or replace the contaminated item. What they cannot do is fix a surgical site infection caused by a contamination that nobody reported.

Know the difference between sterile and non-sterile. As a non-scrubbed rep, you are non-sterile. The computer screen you are looking at, the C-arm you are standing near, the stool you are sitting on — all non-sterile. The imaginary line between you and the sterile field is absolute. If you are ever uncertain whether something is sterile, treat it as sterile and do not touch it.

Where to Stand, Where Not to Stand

Positioning in the OR is about more than etiquette. It is about safety, sight lines, and not being in the way.

The General Rule

Stay where you can see and hear the surgeon without impeding anyone’s movement or compromising the sterile field. This usually means:

• Near the foot of the bed or at the periphery of the room, positioned where you can see the surgical site (or the monitor if the case is arthroscopic/endoscopic)
• Close enough to the back table that you can communicate with the scrub tech and open implants when needed, but far enough that you are not a contamination risk
• Out of the path between the door and the surgical field
• Away from the anesthesia workstation — that is the anesthesiologist’s or CRNA’s space, and they need clear access to the patient’s airway and IV lines at all times

Positions to Avoid

• Between the back table and the surgical field. This is the scrub tech’s corridor. They are constantly passing instruments and implants between these two points. Standing in this path slows them down and creates contamination risk.
• Directly behind the surgeon. You block the circulating nurse’s access, you are in the way of anyone entering or exiting, and the surgeon cannot see you, which means they do not know you are there.
• Leaning against walls or equipment. It looks unprofessional and it means you are not paying attention. If you need to sit, ask if there is a stool available. Standing for 3-4 hours straight is part of the job.
• In front of the imaging monitors. If the surgeon or team is using fluoroscopy, navigation, or video monitors, do not stand where you block their view.

Every surgeon has preferences about where they want their rep positioned. Some want you right at their shoulder. Others want you at the back table. Ask early and respect the answer. If you are unsure on your first case with a new surgeon, ask the scrub tech or circulating nurse where the rep usually stands. They will tell you.

How to Interact with the Surgeon During a Case

The way you communicate with a surgeon during a live case is fundamentally different from how you communicate in a clinic, a lunch meeting, or a sales call. Different rules apply.

Speak When Spoken To — At First

When you are new to a surgeon’s OR, follow their lead on communication. Some surgeons want their rep actively engaged throughout the case, calling out implant sizes, suggesting adjustments, and providing technical input. Others want silence unless they ask a direct question. You will not know which type your surgeon is until you observe them in action. Default to quiet competence. Speak when you have critical information to share or when the surgeon asks. Do not fill silence with chatter.

Keep It Clinical

During the procedure, every word out of your mouth should be relevant to the case. No small talk during critical steps. No sales pitches mid-surgery. No anecdotes about other surgeons or other cases unless the surgeon specifically asks for a comparison. When the drapes are up, you are a clinical support resource, not a sales rep.

There are natural pauses in most surgeries — while waiting for imaging, during wound closure, between implant steps. Some surgeons relax during these moments and welcome casual conversation. Some do not. Read the room.

How to Provide Technical Input

If the surgeon asks for your input on sizing, implant selection, or technique, be direct and specific. “Based on the templating, a size 5 femoral component with a 9mm poly looks right, but the trial looks a little tight in flexion — you might consider the 10mm” is useful. “Whatever you think, doctor” is useless. You are in the room because you know the product. If the surgeon asks your opinion, give a real one.

If you see something that concerns you — a sizing issue, an instrumentation problem, a mismatch between what the surgeon requested and what is on the table — speak up. Do it respectfully, do it clearly, and do it once. “Dr. Smith, I want to make sure you know we have the size 4 and 6 stems available but the 5 was not in the tray today. I flagged it with the tech before we started.” The surgeon makes the final decision. Your job is to ensure they have accurate information.

Never Undermine the Surgeon

Do not criticize the surgeon’s technique, question their decisions in front of the team, or compare them unfavorably to other surgeons. If you believe there is a genuine patient safety issue, address it privately with the surgeon or, in extreme cases, through the facility’s chain of command. Publicly second-guessing a surgeon during their own case is a career-ending move.

Working with OR Nurses and Surgical Techs

New reps make a critical mistake when they focus all their attention on the surgeon and treat the nursing staff as background. The OR nurses and surgical techs are the people who determine whether you have a good experience or a miserable one in their room. They can make your job easier or they can make it nearly impossible, and they will base that decision on how you treat them.

The Scrub Tech Is Your Partner

The scrub tech manages the sterile field, handles your instruments and implants, and is your primary point of contact during the case. Build this relationship deliberately:

• Learn their name and use it
• Brief them on the tray layout and instrument sequence before the case starts
• Be patient when they are learning a new tray or system
• If they hand something to the surgeon and you see it is the wrong instrument, tell the scrub tech quietly so they can make the correction
• After the case, help with the tray count and reconciliation if the facility allows it

The Circulating Nurse Runs the Room

The circulating nurse (circulator) is the non-sterile member of the nursing team who manages the overall flow of the case. They open supplies, document the procedure, handle specimens, coordinate with anesthesia, and manage everything happening outside the sterile field. They are often the first person to notice if a rep is doing something wrong, and they have the authority to ask you to leave the room.

Respect the circulator’s authority. If they ask you to move, move. If they ask you to step out while they handle a patient issue, step out. If they tell you a facility policy you were not aware of, follow it without argument. You can clarify policies later with the OR director. In the moment, the circulator’s word is law.

General Principles

• Introduce yourself to the entire team before every case, even if you have been there before
• Do not sit while the team is standing and working
• Offer to help with non-clinical tasks if appropriate (holding a door, getting supplies from the sub-sterile room)
• Thank the team after every case
• Bring food or coffee for the OR staff occasionally — not as a bribe, but as a genuine gesture of appreciation for people who work incredibly hard

Phone Use and Documentation

Your phone is a necessary tool for case documentation, surgeon communication, and implant record-keeping. It is also a liability if used inappropriately.

Facility Policies Vary

Some facilities prohibit phone use in the OR entirely. Some allow it for clinical documentation only. Some have no explicit policy. Know the rules before you pull your phone out. When in doubt, ask the circulator or the charge nurse.

What Is Acceptable

• Photographing implant stickers and lot numbers for billing and documentation
• Referencing product information or surgical technique guides on your phone
• Texting the surgeon’s office to relay post-case information the surgeon requests
• Communicating with your warehouse about implant availability for the current case

What Is Not Acceptable

• Taking photos or videos of the surgical field, the patient, or the procedure (this is a HIPAA violation and potential grounds for immediate termination of your OR access)
• Scrolling social media, checking email, or browsing the internet during a case
• Taking personal calls in the OR
• Texting about non-case-related matters while surgery is in progress

If you need to take an urgent call during a case, step out of the OR, handle it in the hallway, and return. Do not conduct personal business in the room where a patient is having surgery. The perception alone — a vendor on their phone while a patient is on the table — is damaging.

Mistakes That End Your OR Access

Some errors in the OR are forgivable. These are not.

• Contaminating the sterile field and not reporting it. If you break sterile and try to hide it, you have demonstrated that you value your comfort over patient safety. There is no coming back from this if it is discovered.
• Photographing the patient or the procedure. HIPAA violation. Potential legal liability for you, the surgeon, and the facility. Immediate and permanent loss of access.
• Arguing with the surgeon during a case. Disagreements about implant selection or technique are handled calmly, professionally, and privately. Raising your voice or arguing in the OR is unacceptable.
• Showing up unprepared with missing implants or instruments. If the surgeon planned a case based on the products you committed to providing, and those products are not there, the case may be delayed or canceled. A patient was prepped for surgery and did not get it because you failed at logistics. Once is a serious mistake. Twice, and you will be replaced.
• Inappropriate conversation. The patient may be under anesthesia, but the room is not a locker room. Inappropriate jokes, offensive language, or unprofessional commentary about patients, staff, or other surgeons will be reported and will result in consequences.
• Being visibly distracted or disinterested. Leaning against the wall, yawning, checking your phone repeatedly, or looking bored during a case signals contempt for the work being done. The surgeon and the team notice. They will find a rep who cares.

Building Trust Over Time

OR trust is earned incrementally and lost instantly. Here is how it builds over time.

Your first few cases with a new surgeon or at a new facility are an audition. The team is evaluating whether you know your products, respect the sterile field, communicate appropriately, and add value to the case. Pass this audition and you earn the right to come back. Fail it and you may not get another chance.

Over time, trust deepens through consistency. The surgeon learns that you always have the right products, you always know the case plan, you always show up early, and you always have useful technical input when asked. The scrub tech learns that your trays are always complete, your instruments work, and you brief them thoroughly before every case. The circulator learns that you follow their rules, respect their authority, and do not create problems.

This trust is your most valuable professional asset. It is what separates a new rep from a veteran. It is what keeps surgeons loyal to you even when a competitor offers a lower price. It is what gets you invited to complex cases where the surgeon needs a rep they can count on. And it is built one case at a time, over months and years, by showing up and doing the work right.

For reps exploring what a medical device sales rep actually does, the OR is where the job gets real. Everything else — the sales calls, the territory management, the business development — exists to earn the right to stand in that room and support a surgical team. If you are considering this career path, explore the distribution opportunities available and understand that OR excellence is the foundation of everything that follows.

Frequently Asked Questions

What happens if I accidentally break the sterile field during a case?

Stop what you are doing and immediately tell the scrub tech or circulating nurse what happened. Be specific: “I brushed the corner of the back table drape with my arm.” The team will assess the situation and determine whether re-draping, re-sterilizing instruments, or replacing a contaminated item is necessary. Honest, immediate reporting is expected and respected. The team deals with sterile breaks routinely — from any member of the surgical team, not just reps. What they will not tolerate is a rep who hides a contamination. Report it, let the team handle it, learn from it, and do not repeat it. Your credibility goes up, not down, when you self-report honestly.

How should I handle a surgeon who is rude or demeaning in the OR?

Unfortunately, surgical culture still includes surgeons who are verbally aggressive, demeaning, or unprofessional toward reps and staff. In the moment, stay calm and professional. Do not match their tone or escalate the situation. If the behavior is directed at you personally and is persistent, address it privately with the surgeon after the case. If it continues, you have the right to decline to cover that surgeon’s cases — your distributor or agency should support that decision. No commission check is worth repeated abuse. If the behavior crosses into harassment or discrimination, document it and report it to the facility’s compliance department. Hospitals take these reports more seriously than they used to, and most have policies that apply to surgeon behavior toward vendors.

Can I scrub into a case as a medical device rep?

In most facilities, device reps do not scrub in (gown and glove to work within the sterile field). Your role is typically non-sterile: supporting from outside the sterile field, opening implants, communicating with the scrub tech, and providing technical guidance verbally. Some facilities allow reps to scrub in for specific circumstances — complex cases requiring hands-on instrumentation assistance, product training cases with a surgeon learning a new system, or revision surgeries where the rep’s technical knowledge of the implant system is critical. If scrubbing in is needed, it requires facility approval, and you must follow the same scrub protocol as the surgical team: full surgical hand scrub, sterile gown and gloves, and adherence to all sterile field rules as a scrubbed team member.

What credentials do I need before I can enter the operating room as a device rep?

Every facility sets its own credentialing requirements, but the standard baseline includes: registration with a vendor credentialing service (RepTrax, Vendormate/GHX, or facility-specific systems), up-to-date immunizations (Hepatitis B, Tdap, annual influenza), tuberculosis testing within the past 12 months, a background check, HIPAA training certification, bloodborne pathogen training, professional liability insurance, and completion of the facility’s vendor orientation program. Some facilities require additional certifications specific to the department or specialty. Processing time varies from a few days to several weeks. Start the credentialing process as soon as you know you will be covering cases at a new facility — do not wait until the day before your first case.
