Standard Operating Procedure: Operating Theatre (OT) Management

This Standard Operating Procedure (SOP) outlines the mandatory protocols for the management, preparation, and operation of the Operating Theatre (OT) suite. The primary objective is to maintain a sterile environment, ensure patient safety, minimize the risk of Surgical Site Infections (SSIs), and optimize surgical workflow efficiency. Adherence to these guidelines is non-negotiable for all clinical and support staff to ensure the highest standards of perioperative care.

1. Pre-Operative Preparation and Sterilization

• Environmental Control: Ensure the OT ventilation system is functional, maintaining positive pressure airflow and optimal temperature (18°C–22°C) and humidity (30%–60%).
• Surface Disinfection: Wipe down all horizontal surfaces, including tables, monitors, and light handles, with an approved hospital-grade disinfectant at least 30 minutes before the first case.
• Supply Verification: Confirm the availability of all required surgical instruments, implants, and consumables based on the preference card. Ensure all sterile packs are intact and within the expiration date.
• Equipment Check: Perform a "Pre-flight" check on anesthesia machines, suction apparatus, electrosurgical units (diathermy), and patient monitors.

2. Patient Reception and Verification

• Identification: Verify the patient’s identity using three identifiers: Full Name, Date of Birth, and Medical Record Number (MRN).
• Consent: Confirm that the informed consent form is signed, witnessed, and matches the surgical site and procedure.
• Safety Huddle: Conduct a "Pre-Procedure Briefing" with the surgeon, anesthesiologist, and nursing team to confirm the patient, procedure, and site.
• Site Marking: Ensure the surgical site is clearly marked by the operating surgeon while the patient is awake and aware.

3. Intra-Operative Protocol

• Surgical Scrub: All sterile team members must perform a rigorous 3–5 minute surgical scrub using an antiseptic agent, followed by donning sterile gowns and gloves.
• Sterile Field Maintenance: Maintain the integrity of the sterile field at all times. Any breach in sterility must be reported immediately, and the compromised item must be replaced.
• Time-Out: Immediately before the first incision, perform a formal "Time-Out." Every team member must stop to confirm the patient identity, procedure, site, and prophylactic antibiotic administration.
• Count Policy: Conduct standardized counts of all sponges, sharps, and instruments at the beginning of the case, before closure of a cavity, and at final skin closure.

4. Post-Operative and Turnover Protocol

• Patient Handover: Provide a structured SBAR (Situation, Background, Assessment, Recommendation) report to the PACU (Post-Anesthesia Care Unit) nursing staff.
• Specimen Handling: Ensure all surgical specimens are correctly labeled, documented, and sent to the pathology laboratory immediately.
• Room Turnover: Dispose of biohazardous waste according to medical waste management protocols. Strip the table of used linens and perform a terminal cleaning of the theatre to prepare for the next procedure.

Pro Tips & Pitfalls

• Pro Tip (The "Third Eye"): Always designate one circulating nurse to act as the "sterile conscience," whose sole job is to monitor for breaks in sterile technique that others might miss due to focus on the task.
• Pro Tip (Standardization): Use "Preference Cards" for every surgeon and procedure. Updating these cards quarterly reduces setup time by 20% and prevents "supply hunting" mid-surgery.
• Pitfall (The Silent Time-Out): A common failure is treating the "Time-Out" as a box-ticking exercise. If the team is distracted or quiet, the risk of wrong-site surgery increases exponentially. Ensure full eye contact and verbal confirmation from every team member.
• Pitfall (Equipment Fatigue): Never ignore an intermittent alarm on an anesthesia machine or monitor. Always investigate the root cause immediately; "false alarms" are often precursors to equipment failure.

Frequently Asked Questions (FAQ)

Q: What is the procedure if a sponge count is incorrect at the end of a surgery? A: Stop the closure immediately. The surgeon must conduct a thorough physical exploration of the surgical field, and the circulating nurse must search the entire room, including linen bags and trash. If the item is not found, an intra-operative X-ray must be performed before the patient leaves the OT.

Q: How often should the OT be deep-cleaned? A: While daily terminal cleaning is mandatory, a "Deep Clean" (including walls, ceilings, and ventilation ducts) should be performed according to the facility’s Infection Control schedule, typically every 30 days or following a contaminated (dirty) case.

Q: Who has the authority to stop a surgery if a safety breach occurs? A: Every member of the OT team, regardless of seniority, has the "Stop-Work Authority." If anyone identifies a safety hazard, they are empowered to pause the procedure immediately until the risk is mitigated.
