Assembling Devices into Trays

Study Notes

Devices are arranged from left to right in the order they will be used in a procedure.
Devices can also be arranged by size to prevent tangling.
A checklist should be used to ensure consistency and accuracy.
All contents of a surgical instrument tray must be checked and verified against the checklist.

Forceps should be placed on instrument pins to hold them together and reduce tangling.
Follow the manufacturer's instructions for devices that require special sterilization or disassembly.
Leave forceps with ratchets open, or close them on the first ratchet only, to ensure steam penetration.
Spread devices evenly over the tray surface to prevent condensate from flowing together.
Place plastic items evenly in the tray, avoiding collection in one area.
Use validated tip protectors and tray liners or silicone mats to protect delicate devices.

The type of packaging material and technique used depends on the items to be packaged and the sterilization process.
Packaging materials must provide an effective barrier to microbial penetration, protect devices from contamination, and allow aseptic delivery.
Common packaging materials include rigid containers, peel pouches, and sterilization wraps.
Sterilization wraps are the most commonly used method.

Sequential wrapping involves wrapping two layers of wrap material individually using a fold technique.
Simultaneous wrapping involves wrapping both layers together simultaneously.
Square fold and envelope fold techniques are used with sequential and simultaneous wrapping methods.

Rigid reusable containers are making a comeback due to improved technology and cost-effectiveness.
Peel-apart pouches are used to pack small lightweight single instruments.
The type of pouch used depends on the sterilization method being used.
Peel pouches can be made of medical-grade paper/plastic or spunbond polyolefin-plastic (Tyvek).
The choice of pouch material depends on the sterilization method used.
Pouches should be sealed carefully, and the identification of packed devices should be easy due to the transparent plastic film.
