After a tracheostomy procedure, which item should remain sterile on the back table until the patient leaves the room?

In the context of a tracheostomy procedure, the tracheostomy hook and spreader should remain sterile on the back table until the patient leaves the room. This is primarily because these instruments are used to maintain an adequate surgical field and support the tracheostomy while minimizing contamination risks during the procedure.

Maintaining sterility of the hook and spreader is crucial because they are not only involved in the initial placement but may also be used for stabilization during the immediate postoperative period. If they become contaminated, it could lead to infection or complications.

Other items, like the tracheostomy obturator and inner cannula, play specific roles that may involve direct contact with the stoma or the airway. Once the placement is secure, their sterility may be less critical compared to the instruments used to assist in opening the airway initially. The endotracheal tube is often removed as it is used for ventilation during surgery and may not be necessary after the tracheostomy is secured. Hence, the total need for various items can differ based on the step of the procedure and the need for sterile conditions.
