Choosing a surgical instrument cart and case cart for OR-CSSD transport

Dirty and clean transport: why two flows

Used instruments and sterile sets must never share a cart. The dirty flow needs a closed, easily washable case cart with a lid or doors, so that blood, tissue and aerosols are contained on the way from the theatre to the decontamination room. The clean flow needs a cart or rack that protects sterile packs and containers from dust, splashes and handling damage.

Many hospitals keep dirty and clean carts visibly different, by colour, labelling or design, and wash the dirty ones in a cart washer after every shift. Decide this at the planning stage, because it drives how many carts you need and how much floor area the CSSD requires for cart parking and washing.

Closed case carts versus an open surgical instrument cart

Closed case carts have solid walls and a lockable door, which makes them suitable for both soiled transport and for sterile storage on the move. Open trolleys with wire shelves ventilate well and are easy to load, but they offer little protection and are better kept inside the CSSD for assembly or loading the steriliser.

• Closed case cart: best for dirty returns and for sterile delivery along public corridors.
• Open wire trolley: assembly area, steriliser loading and unloading, cooling rack.
• Wall-less shelf rack: sterile store, as long as the room meets storage conditions.

Matching racks to trays and containers

Check the footprint of your trays before you check the cart. Rigid containers come in set sizes; for example, REDA sterilization containers are listed with full-size, three-quarter and half-size bases of 580, 465 and 285 × 280 mm. An instrument tray rack or instrument tray stand must carry the largest container you use with a margin for handles, and extra-large containers need a rack designed for them.

Large trays and tall containers call for adjustable shelf heights or guide rails, so stacks do not tilt on thresholds. Ask for the safe working load per shelf and per cart, and calculate the weight of a loaded full-size container, since heavy sets are a common cause of strained backs and dropped trays.

Specification checklist for hospital buyers

Compare carts on construction first. Stainless steel is the usual choice for washable surfaces; look at welds, edges and door seals, which should be free of crevices where soil can hide. Check castor size and braking, since carts cross lifts and door thresholds, and whether the handles allow two-hand steering without hitting door frames.

Then review compatibility with your processes: does the cart fit your lift, the doors of the cart washer and the sterile store aisles? Can the shelf configuration be changed later? Request cleaning instructions and a spare parts list so that castors and seals can be replaced without replacing the cart.

Cost, quantity and procurement notes

A cssd trolley price depends on material, closed or open design, locking, shelf adjustability and castor quality, so quote requests should state the tray sizes, daily set volume and corridor route. A useful rule is to size the fleet to peak turnover plus a spare, not to the average day. Fewer carts than flows creates queueing and the temptation to mix clean and dirty.

Also ask whether the supplier can support installation planning, delivery and after-sales parts. If you are fitting out a new department, review CSSD design and layout and the CSSD equipment list together so trolleys are specified with washers, sterilisers and storage.
