Sterility

How to move in the operating room without contaminating the sterile field

Move safely by planning your route, controlling contact and making uncertainty visible before it spreads.

Early in my practice, I contaminated a sterile drape without realising it immediately. I was opening equipment with one goal: be quick. In my haste, my hands moved too far forward and touched the sterile inner surface.

The lesson was not simply “be more careful”. It was that speed without a clear map of surfaces and movement creates risk.

Decide the route before you move

Before carrying equipment, changing position or approaching a sterile table, look at the whole route:

  • Where is the sterile field?
  • Which areas can I see clearly?
  • Who may move at the same time?
  • Are cables, stands or trolleys narrowing the space?
  • Where will I stop and where will the item be received?

A second of planning prevents a last-moment correction close to the field.

Opening sterile supplies is a handover

Opening a pack is not merely removing wrapping. It is a controlled transfer from an unsterile exterior to a sterile recipient or field. Follow the product instructions and local method. Position yourself so the item can be presented without reaching over the field or allowing the wrapper to spring back.

If the opening does not proceed as expected, stop. Do not rescue an uncertain transfer with a faster movement.

Moving around sterile people

Sterile team members need to preserve the sterile areas of gowns and gloves while also maintaining awareness of tables and the draped patient. When space is limited, communicate before passing, turning or changing position.

Rules about how sterile personnel pass one another must follow local policy and training. Do not rely on a remembered shortcut from another workplace.

Control the urge to squeeze through

When the room is busy, the shortest route may look efficient. But passing through a narrow gap can bring clothing, equipment or an unseen surface close to the field.

Ask for space. Move a trolley through an agreed route. Wait for a colleague to finish a movement. A clear verbal warning is more professional than silently hoping there is enough room.

If contact may have occurred

Stop and state what you saw or felt. Identify the relevant surface and follow local policy. Do not let embarrassment turn a small, manageable event into an invisible chain of further contacts.

Try one exercise on your next shift: before every approach to the sterile field, pause for one second and name your route and destination internally. With repetition, deliberate movement becomes natural without becoming careless.
