Purpose of an Organized Setup
A consistent, organized back table and Mayo stand setup allows the scrub person to locate instruments instantly without looking away from the field, supports accurate counts, and reduces the risk of instrument damage or contamination. Most facilities and specialties follow a standardized layout so any scrub person can step into a room and find items quickly.
Back Table Organization Principles
- Group instruments by type and function: clamps together, scissors together, retractors together, etc.
- Arrange items in the order they will typically be used during the procedure, when practical.
- Keep ring-handled instruments organized on a stringer or instrument rack, sorted by size and type.
- Basins, medicine cups, and solutions are placed in a consistent, labeled location to prevent mix-ups (especially between look-alike solutions).
- Sharps (needles, blades) are kept in a designated neutral zone or sharps container area for hands-free passing.
Typical Back Table Layout Zones
| Zone | Typical Contents |
|---|---|
| Linen/drape zone | Folded towels, gowns, additional drapes not yet used |
| Basin zone | Prep and irrigation basins, solutions clearly labeled |
| Instrument zone | Main tray instruments organized by category |
| Suture/sharps zone | Suture packets, needle counter, blades |
| Sponge zone | Counted sponge packages, kept separate from used/soiled sponges |
| Supply zone | Extra gloves, dressings, specimen containers, miscellaneous disposables |
Mayo Stand Setup
The Mayo stand holds the instruments used most frequently during the current step of the procedure - it is the scrub person's immediate working surface, positioned over the patient's lower body or as directed by the surgeon.
- Cover the Mayo stand with a sterile Mayo stand cover before placing any instruments on it.
- Common setup order (left to right or by facility convention): scalpel, tissue forceps, dissecting scissors, hemostats, needle holder with suture loaded, and the primary retractor in use.
- Only instruments needed for the immediate next steps belong on the Mayo stand - it should not become a second back table.
- Return instruments to their designated spot after use so the layout stays predictable throughout the case.
Sponge and Sharps Safety on Setup
- Sponges are opened in standard counted packages and never mixed with an already-open package.
- A designated hands-free "neutral zone" (such as a magnetic pad or basin) is used for passing sharps to reduce the risk of a sharps injury during transfer.
- Loaded needle holders are passed with the point directed away from the surgeon and scrub person, following the neutral zone technique whenever possible.
Key Exam Points
- An organized, standardized setup improves efficiency and supports patient safety by reducing the chance of instrument loss, damage, or count discrepancy.
- The scrub person maintains constant awareness of every item on the sterile field, including the back table and Mayo stand, throughout the procedure.
- Solutions on the back table must always be labeled immediately when poured, including the name and strength, to prevent medication errors.
- Heavier or bulkier instruments generally stay on the back table, while frequently used items for the current step move to the Mayo stand.
