When should dressing sponges be opened to the sterile field?

Dressing sponges should be opened to the sterile field after the final closing count to maintain sterility and prevent contamination. This practice is essential because it ensures that all items present in the sterile field, including sponges, are accounted for before any item is added that could interfere with that count.

Opening dressing sponges after the final count helps to prevent any confusion or potential loss of a sponge inside the surgical site, which is a critical concern during surgery. Additionally, it allows the surgical team to confirm that the area is clear and that proper protocols for maintaining a sterile environment have been followed up to that point.

Timing the introduction of dressing sponges after the final closing count also ensures that the sponges can be placed into the sterile field without affecting the tally of sponges used during the procedure, which is crucial for patient safety and prevents the risk of retained foreign objects.
