Standard Operating Procedure: Operating Theatre (OT) Readiness and Safety Checklist

This Standard Operating Procedure (SOP) outlines the mandatory protocol for preparing the Operating Theatre (OT) to ensure patient safety, minimize surgical site infections, and optimize team efficiency. Adherence to this checklist is non-negotiable for all clinical and support staff to maintain the highest standards of perioperative care and sterile processing.

1. Environmental and Equipment Readiness

• HVAC Systems: Verify the OT ventilation system is operational, with positive pressure maintained and HEPA filters checked for current certification.
• Surface Disinfection: Ensure all high-touch surfaces, anesthesia work surfaces, and instrument tables have been cleaned with hospital-grade disinfectant according to the terminal cleaning schedule.
• Anesthesia Machine Check: Execute a full pre-use checkout (FDA guidelines), including oxygen supply, circuit integrity, CO2 absorber status, and backup ventilation battery power.
• Lighting and Imaging: Test the main surgical lights and peripheral overhead lights for intensity and positioning. Verify the functionality of C-arm or imaging monitors.

2. Sterile Supplies and Instrumentation

• Tray Verification: Confirm the surgical instrument set matches the procedure booked. Inspect outer packaging for integrity, dryness, and indicator color change.
• Sterility Expiry: Check the expiration date on all peel-packed items, implants, and sterile solutions.
• Supplementary Supplies: Verify the availability of necessary sutures, drapes, cautery pads, and specialized disposables specific to the surgeon’s preference card.
• Emergency Equipment: Ensure the crash cart is sealed and current, and the difficult airway trolley is present and fully stocked.

3. Patient Safety and Verification (WHO Surgical Safety Checklist)

• Patient Identification: Verify patient identity, procedure, site, and consent against the surgical booking form.
• Site Marking: Confirm the surgical site is marked and visible if applicable.
• Allergy Check: Explicitly announce and verify all known drug or latex allergies with the anesthesia provider and circulating nurse.
• Equipment Readiness: Confirm all necessary implants or specific equipment are in the room before the patient is induced.

4. Final Safety "Time-Out"

• Pre-Incision Stop: Perform the mandatory "Time-Out" where all team members stop activity to confirm:
  • Patient Name and Procedure.
  • Prophylactic antibiotic administration (within 60 minutes).
  • Expected critical events (blood loss, specific instrumentation needs).
  • Sterility confirmation by the scrub nurse.

Pro Tips & Pitfalls

• Pro Tip: Maintain a "clean-as-you-go" policy. Do not allow excess waste to accumulate, as it hides potential hazards and increases the risk of contamination.
• Pitfall - The "Normalization of Deviance": Never bypass the "Time-Out" process because the team is "familiar" with the surgeon or the case. Every patient deserves the full safety protocol regardless of procedure complexity.
• Pro Tip: Use digital tracking for surgical count reconciliation to minimize human error during sponge and instrument counts.
• Pitfall - Inadequate Communication: Many errors occur during shift changes. Ensure a formal "handover" protocol is followed if staff rotation occurs mid-procedure.

Frequently Asked Questions (FAQ)

Q: What should be done if a sterile package is found with a tear but the internal indicator shows it is still sterile? A: Do not use the package. Any breach in the outer barrier classifies the item as non-sterile, regardless of the internal indicator status. Replace it immediately to maintain the aseptic field.

Q: Who is responsible for initiating the Surgical Time-Out? A: The circulating nurse or the surgeon typically initiates the Time-Out. However, it is the responsibility of every single person in the room to ensure it occurs before the incision is made.

Q: How frequently should the OT humidity and temperature be logged? A: Environmental parameters should be checked and logged at the start of every shift and again before the first case of the day. If the OT remains in constant use, logging should occur at least every four hours or as per facility policy.
