What Is A Back Table?

A back table is a sterile table used in the operating room to hold surgical instruments, supplies, and equipment for a procedure. It is set up before surgery and covered with a sterile drape. The back table holds items that may be needed during the case but are not kept directly on the Mayo stand. It helps the scrubbed team keep extra sterile supplies organized and ready.

How Is A Back Table Used?

The surgical team arranges instruments, sponges, sutures, basins, and procedure supplies on the sterile surface. Items are placed in a way that helps staff find them without breaking sterile technique. Frequently used tools may move to the Mayo stand, while backup or later-use items stay on the back table. The setup can vary by procedure, surgeon preference, and facility policy.

What Goes On A Back Table?

A back table can hold instrument sets, sterile bowls, dressings, sutures, implants, tubing, drapes, and selected device parts. Sharps and delicate instruments should be placed where they are visible and protected. Heavy trays should be positioned safely so the table stays stable. Items that fall below sterile field level or touch nonsterile surfaces should be handled according to facility policy.

Back Table Sterile Field Rules

The back table is part of the sterile field once it is draped and opened with sterile supplies. Only sterile team members should touch sterile items on the table. Staff should avoid reaching over nonsterile areas or turning away in a way that risks contamination. If sterility is in doubt, the item or field should be treated as contaminated based on policy.

Back Table Cleaning And Safety

After the procedure, reusable instruments go through the approved cleaning and sterilization process. The table surface, wheels, frame, and supports should be cleaned and checked for damage. Unstable wheels, loose parts, or a damaged surface can create safety problems in the operating room. A clear setup and count process also helps reduce retained item risk.

Frequently Asked Questions About Back Tables

Is A Back Table The Same As A Mayo Stand?

No. A back table holds extra sterile instruments and supplies, while a Mayo stand sits closer to the surgical field with frequently used tools. Both support the sterile setup.

Is The Back Table Sterile?

The table itself is not sterile until it is properly draped and set up with sterile supplies. Once prepared, the sterile surface must be protected from contamination.

Who Sets Up The Back Table?

A scrubbed team member, such as a surgical technologist or scrub nurse, commonly sets up and manages the back table. Facility policy and procedure type can affect exact roles.

What Happens If Something On The Back Table Is Contaminated?

The contaminated item should not be used. Staff follow facility policy, which can include removing the item, replacing supplies, or correcting the sterile field.
