2.6 Surgical Counts & Specimen Management

Why and When Counts Are Performed

Surgical counts exist to prevent a retained surgical item (RSI) — a sponge, sharp, or instrument left inside the patient, a "never event." The scrub (CST) and circulator count together, each item visually and audibly, one at a time, and the circulator records the result.

Counts are performed at minimum at these points:

Counts are done in a consistent order (e.g., from the surgical site outward to the Mayo stand, back table, then off-field/discarded items). Items are counted in the same sequence every time to avoid omissions.

What Is Counted and the Discrepancy Protocol

Three categories are counted: sponges, sharps, and instruments, plus miscellaneous items (vessel loops, umbilical tape, bovie tip cleaners).

• Sponges are counted by type and in standard package counts (e.g., Raytex/raytec in packs of 10, lap sponges in packs of 5). Radiopaque sponges have an x-ray-detectable strip. The package count is verified — a pack with the wrong number is bagged and removed from the field, not used.
• Sharps include scalpel blades, suture needles (counted individually, even multi-pack), hypodermic needles, and electrosurgical blade tips. Used needles go in a needle counter/sharps container.
• Instruments are counted against a standard count sheet.

Discrepancy (incorrect count) protocol:

1. Notify the surgeon immediately; the wound is not closed.
2. Search the field, drapes, floor, kick buckets, and trash.
3. The team repeats the count.
4. If still missing, an intraoperative X-ray is taken before closure to locate the radiopaque item.
5. The event is documented (including any retained item left intentionally with surgeon notation), and an incident report is filed per facility policy.

Counts are not waived for emergencies, but if a true life-threatening emergency prevents an initial count, the omission is documented and an x-ray is taken postoperatively.

Several practical habits prevent discrepancies in the first place. Sponges are never used to wipe instruments or cut into pieces, because a fragment cannot be reliably counted. Throat packs and laparotomy sponges placed inside a cavity are tracked deliberately, often clamped to a visible instrument or noted on the board so they are not forgotten. Needles are kept on the needle book and counted as they come off, and a broken instrument is reported so all pieces are accounted for. The CST also resists the temptation to remove anything from the room — sponges, sharps, and instruments stay until the final count is correct.

Specimen Management

A specimen is tissue, fluid, or a foreign body removed for examination. Mishandling can require re-operation, so the CST follows strict handling:

• Pass specimens off the field promptly to the circulator; do not let them dry out (keep on a moist sponge or in saline unless told otherwise).
• Identify each specimen aloud to the circulator using the exact source and any orientation (e.g., "right breast, lateral margin marked with a long stitch"). Never guess later from memory.
• The circulator labels the container (not just the lid) with the patient's name, identifiers, specimen source/site, and the surgeon's name, and completes the requisition.
• Match the preservative to the test: most go in formalin; a frozen section goes fresh (no formalin), and cultures go in appropriate media. Tissue for special studies (hormone receptors, flow cytometry) often must stay fresh.
• Chain of custody matters for forensic specimens (bullets, evidence) — handle with instruments, document, and hand off to the proper authority.

All medications and solutions on the field are labeled (name, strength, amount, expiration) the moment they are received, the same discipline that protects specimen accuracy.

Count Accountability, Documentation, and Adjuncts

Counts are a shared responsibility between the scrub (CST) and the circulator, but both must participate — one person counting alone is not acceptable, because the verification depends on two sets of eyes confirming the same number aloud. The CST keeps the field organized so counting is fast and reliable: sponges are separated and never cut, needles are kept on a needle book or magnetic pad, and used items are passed off the field in a controlled way rather than discarded loose.

Documentation of every count is mandatory. The circulator records the counts as correct or incorrect, the names of the personnel who counted, the time, the results reported to the surgeon, and any actions taken for a discrepancy (search, X-ray, and the outcome). A correct count is documented; an unresolved discrepancy and any intentionally retained item are documented in detail with the surgeon's notation.

Adjunct technologies support but do not replace the manual count:

Even with technology, the manual two-person count remains the standard, and a discrepancy is always resolved before the patient leaves the room. This rigor is why retained surgical items are classified as preventable "never events."
