Standard Operating Procedure: Operating Theater (OT) Management

This Standard Operating Procedure (SOP) outlines the standardized clinical and administrative workflow for the Operating Theater (OT) to ensure patient safety, minimize infection risks, and optimize procedural efficiency. By adhering to these protocols, the surgical team ensures a sterile environment, consistent equipment availability, and seamless transitions between surgical cases. Compliance with these procedures is mandatory for all clinical staff, including surgeons, anesthesiologists, nursing staff, and technicians.

Phase 1: Pre-Operative Preparation

• Case Verification: Confirm the patient’s identity, surgical site, and procedure against the consent form and surgical schedule.
• Environmental Check: Ensure the OT temperature (typically 18°C–22°C) and humidity are within the specified range for sterile integrity.
• Equipment Audit: Verify all specialized surgical instruments, implants, and laparoscopic towers are functional and calibrated.
• Sterility Validation: Inspect all sterile packs and instrument trays for chemical indicator changes and integrity of the sterile barrier (no tears or moisture).
• Anesthesia Setup: Confirm the anesthesia machine is pre-checked, airway equipment is ready, and emergency medications/defibrillator are functional.

Phase 2: Intra-Operative Conduct

• Surgical Scrub: Perform the prescribed 3-to-5-minute surgical scrub using medical-grade antiseptic, ensuring proper hand-to-elbow technique.
• Gowning and Gloving: Execute closed-gloving techniques within the sterile field, ensuring assistants remain within the designated sterile zone.
• Time-Out Procedure: Perform the mandatory WHO Surgical Safety Checklist "Time-Out" immediately before skin incision, involving all team members to confirm patient identity, site, and procedure.
• Counting Protocol: Conduct the initial sponge, needle, and instrument count before the incision, and perform subsequent counts prior to fascial/cavity closure.
• Field Maintenance: Maintain a constant sterile field; monitor and replace any contaminated drapes or instruments immediately.

Phase 3: Post-Operative Transition

• Final Count: Ensure the final instrument and sponge count is reconciled by the scrub nurse and circulator before final skin closure.
• Specimen Handling: Label all tissue specimens correctly, ensuring they are logged in the registry and handed over to the laboratory with the appropriate request forms.
• Patient Handoff: Complete a structured verbal handoff to the PACU (Post-Anesthesia Care Unit) nurse, detailing intra-operative complications, fluid balance, and medication administered.
• Room Turnover: Direct the disposal of biohazardous waste, clean and disinfect all surfaces per hospital infection control protocols, and prepare the room for the subsequent case.

Pro Tips & Pitfalls

• Pro Tip: The "Two-Voice" Rule. When performing the surgical count, ensure two people count aloud simultaneously to prevent cognitive errors during high-stress procedures.
• Pitfall: Equipment Dependency. Never rely solely on electronic monitoring; always perform a physical assessment of the patient’s clinical status (pulse, respiration, color) as the primary indicator.
• Pro Tip: Proactive Supply Management. Keep a "crash cart" of frequently requested items (sutures, dressings, catheters) stored in the OT to minimize personnel entering and leaving the room during surgery.
• Pitfall: Communication Silos. Avoid "siloing" information. If a potential infection risk or instrument malfunction is spotted, communicate it immediately regardless of rank or hierarchy.

Frequently Asked Questions (FAQ)

Q: What is the procedure if a surgical sponge count is incorrect? A: Immediately inform the surgeon. The team must pause the surgery, conduct a visual inspection of the sterile field, and perform a secondary manual search. If still missing, an intra-operative X-ray must be performed before the patient leaves the operating room.

Q: How often should the air filtration system be monitored? A: Air pressure gradients should be monitored continuously via the pressure gauge outside the OT door. HEPA filter integrity must be validated through scheduled facility maintenance every 6 months.

Q: Can a non-scrubbed staff member touch the sterile field? A: Absolutely not. Only sterile-gowned and gloved personnel may touch the sterile field. Any breach in sterility requires the affected item or area to be discarded or re-sterilized immediately.
