We know that surgeons perform surgery. But who else is part of the process? In our What Do They Do? series, we explore some of the lesser-known but vital team members who help make your surgical care possible. Today, we're learning about the OR nurse.
When you're having surgery, you may not remember much about what happens in the operating room—but there's someone there the entire time making sure you're safe, cared for, and protected. That person is your OR nurse.
So, what exactly does an OR Nurse do?
A Patient's Advocate in the OR
Operating Room nurses—also known as perioperative nurses—are specially trained to care for patients before, during, and after surgery. They work alongside surgeons, anesthesiologists, and surgical techs to make sure each procedure goes as smoothly and safely as possible.
They are your advocates when you can't speak for yourself.
Your Safety Starts Before Surgery
Before your surgery even begins, your OR nurse is already at work. They review your medical history, make sure the correct equipment is in place, and double-check that everything is ready for your specific procedure. They verify your name, procedure, and surgical site—part of a process called the surgical safety checklist.
They also help answer any last-minute questions, calm nerves, and make sure you're as comfortable as possible before going under anesthesia.
A Critical Role During the Procedure
Once surgery starts, your OR nurse plays one of two main roles:
- Circulating Nurse – This nurse stays outside the sterile field and manages the entire room. They monitor everything happening, respond to any needs that come up, and make sure supplies and equipment are available and working properly.
- Scrub Nurse – This nurse works directly in the sterile field, handing instruments to the surgeon and anticipating the team's needs during the procedure.
In both roles, OR nurses are focused on one thing: keeping you safe. That means monitoring for signs of complications, helping to maintain a sterile environment, and advocating for you every moment you're in the OR.
Post-Op and Beyond
After the procedure, your OR nurse helps ensure a smooth handoff to the recovery team, sharing important information about your surgery and any concerns to watch for. Even though you may never fully meet them, OR nurses play a vital role in how you come through surgery.
Focused, Skilled, and Compassionate
Operating Room nurses are highly skilled professionals who must stay calm, alert, and focused—often for long and intense procedures. But they also bring something else to the OR: compassion. They know surgery can be scary, and they work hard to make sure patients feel seen, respected, and protected.
They often help with:
- Preparing the operating room and equipment
- Verifying patient identity and procedure details
- Assisting during surgery as a circulating or scrub nurse
- Monitoring for safety issues or complications
- Communicating with surgical team members
- Ensuring a smooth transition to recovery
When You Might Meet an OR Nurse
You may meet your OR nurse briefly before surgery, or you may only know them through the care they provide while you're under anesthesia. Either way, they are essential to every surgical team—and to your safety and healing. They're the quiet hands guiding you through surgery, every step of the way.
