Standard Operating Procedure: Operating Theater (OT) Management

The Operating Theater (OT) is a high-stakes environment where precision, sterility, and communication are paramount to patient safety. This Standard Operating Procedure (SOP) outlines the mandatory workflows for preparing, conducting, and concluding surgical procedures. By strictly adhering to these protocols, the surgical team minimizes the risk of Surgical Site Infections (SSIs), ensures equipment readiness, and maintains a seamless transition between cases. This document serves as the governing standard for all clinical and support staff within the OT suite.

1. Pre-Operative Preparation & Safety Checks

• Sterilization Verification: Ensure all autoclaved instrument trays are inspected for integrity, proper indicator strips, and expiration dates.
• Environmental Control: Confirm OT temperature is set between 18°C–22°C and humidity between 30%–60%. Ensure Positive Pressure Ventilation is functional.
• Equipment Calibration: Verify the functionality of anesthesia machines, monitors, electrocautery units, and suction apparatus.
• Patient Verification: Conduct a formal "Time-Out" verification including patient identification, surgical site marking, and consent form review prior to anesthesia induction.
• Surgical Scrub: All personnel must perform a surgical scrub for 3–5 minutes using approved antiseptic agents before donning sterile gowns and gloves.

2. Intra-Operative Conduct & Sterile Field Maintenance

• Sterile Field Integrity: Ensure only sterile-draped items are placed on the instrument table. If a sterile barrier is breached, the item must be replaced immediately.
• Traffic Control: Minimize personnel movement within the OT to reduce air turbulence and microbial contamination.
• Continuous Monitoring: Anesthesia staff must maintain continuous hemodynamic monitoring, while the circulating nurse tracks medication administration and sponge/instrument counts.
• Safety "Time-Out": Perform a final brief before the initial incision, confirming the procedure, site, and patient identity with the entire surgical team.
• Specimen Handling: Label all tissue samples immediately after removal, documenting the type and site of origin in the presence of the surgeon and the circulating nurse.

3. Post-Operative Cleanup & Decontamination

• Instrument Reconciliation: Perform the final count of all sponges, needles, and instruments to ensure nothing remains in the operative site.
• Waste Disposal: Dispose of all biohazardous materials, sharps, and linen in designated, color-coded bins according to hospital infectious waste policies.
• Equipment Cleaning: Wipe down all surfaces (OT table, monitors, lights) with hospital-grade disinfectant between cases.
• Patient Transfer: Ensure the patient is hemodynamically stable before transferring to the PACU (Post-Anesthesia Care Unit) with a complete handover report.
• Room Turnover: Document the procedure completion time and prepare the room for the next case by replenishing consumables and sterile supplies.

Pro Tips & Pitfalls

• Pro Tip: Use a "Whiteboard Huddle" at the start of the day to discuss the specific needs for each case (e.g., special implants or positioning equipment) to prevent mid-surgery delays.
• Pro Tip: Maintain a "Clean vs. Dirty" workflow. Never allow the sterile table to be touched by anyone who hasn't scrubbed, regardless of urgency.
• Pitfall (Communication Failure): The most common cause of surgical error is a lack of communication. Never assume the team knows the surgeon’s next move; verbalize intentions clearly.
• Pitfall (Rushed Counts): Never perform the "Instrument Count" while distracted. If the count is incorrect, surgery must pause until the item is located or an intra-operative X-ray is performed.

FAQ

Q: What should be done if the sterile field is accidentally compromised? A: Immediately alert the surgical team. Do not attempt to "fix" the area. Any item touched by non-sterile personnel or dropped below table level must be discarded, and the affected area must be re-draped or re-scrubbed by the surgeon.

Q: How often should the OT environment be deep-cleaned? A: Beyond the standard between-case cleaning, the OT should undergo a terminal clean every 24 hours. This involves a comprehensive disinfection of all surfaces, lights, air vents, and floors.

Q: What is the mandatory protocol for a "Wrong Site" suspicion? A: Stop the procedure immediately. Cease all surgical activity and verify the surgical consent and site marking with the patient’s records and the surgeon. Do not proceed until a formal incident report is filed and the surgical team confirms the correct site.
