12.3 Surgical Suite Fires, Code Blue & Emergency Transfer/Evacuation in the ASC

Surgical Suite Fires, Code Blue & Emergency Transfer/Evacuation in the ASC

Core Principle: Ambulatory surgery centers operate with lean clinical staffing and without immediate access to in-house critical care units, hospital code teams, or on-site fire departments. Managing catastrophic operating room emergencies—surgical suite fires, intraoperative cardiac arrests, and facility evacuations—demands absolute procedural clarity, strict preventive discipline, and seamless interdisciplinary coordination to safeguard anesthetized patients and perioperative personnel.

The Surgical Fire Triangle in Ambulatory Surgery

A surgical fire requires the simultaneous presence of three components: Fuel, an Ignition Source, and an Oxidizer. The operating room represents a uniquely hazardous environment where all three elements converge within centimeters of the patient's body.

1. Fuel Hazards & Skin Antisepsis Rules

• Alcohol-Based Skin Antiseptics: Chlorhexidine gluconate (CHG) with 70% isopropyl alcohol (IPA) or povidone-iodine with alcohol are the most volatile fuels in the surgical suite. Alcohol vapors ignite explosively at room temperature when exposed to an ignition spark.
• Mandatory Drying Times: Alcohol-based preps must dry for a minimum of 3 full minutes on hairless skin and up to 1 hour or longer in hairy or occluded areas before applying drapes. The circulating nurse must verify that the prep is completely dry to touch and that all vapors have fully dissipated.
• Prevention of Pooling: Alcohol preps must never be allowed to pool in the umbilicus, skin folds, under tourniquets, or soak into patient linens/drapes. If pooling occurs, wet linens must be removed and replaced prior to draping.
• Endotracheal Tubes (ETTs): Polyvinyl chloride (PVC) tubes ignite rapidly in oxygen-enriched atmospheres, creating a blowtorch effect that inflicts severe thermal and chemical burns to the tracheobronchial tree.

2. Ignition Sources & Device Safety

• Electrosurgical Units (ESU): The active electrode tip of an ESU pencil is the most frequent ignition source. Standard Safety Rule: The active electrode must be kept in a non-conductive, clean plastic holster whenever it is not in the surgeon's active hand. Never lay an active ESU pencil directly on surgical drapes, patient linens, or stand trays!
• Surgical Lasers: Lasers (CO2, Nd:YAG) ignite dry sponges, drapes, and standard ETTs instantly. Lasers must remain in STANDBY mode at all times until the surgeon is positioned and ready to fire. For airway laser surgery, use specialized laser-resistant metal/cuffed ETTs with cuffs inflated with sterile saline tinted with methylene blue (the blue saline quenches ignition and provides visual indication of cuff perforation).
• Fiberoptic Light Cables: High-intensity light sources emit intense radiant heat. A disconnected light cable resting on surgical drapes can ignite the fabric within 5 to 10 seconds. Always put light sources on STANDBY before disconnecting cables.

3. Oxidizers & Oxygen-Enriched Environments

• The 30% FiO₂ Threshold: An atmosphere containing greater than 21% oxygen is oxygen-enriched; concentrations exceeding 30% FiO₂ drastically accelerate flame spread and lower the ignition temperature of drapes and tissues.
• Head, Neck, and Face Surgery (Above the Xiphoid): Open delivery of 100% oxygen via nasal cannula or simple face mask under surgical drapes creates an explosive oxygen pocket beneath the drape tent. For monitored anesthesia care (MAC) procedures above the xiphoid, guidelines mandate blending oxygen with medical air to deliver <30% FiO₂, maintaining open drape configurations to prevent gas trapping, or using a closed circuit (cuffed ETT or LMA) if high FiO₂ is clinically necessary.

Preoperative Fire Risk Assessment & The Time-Out

AORN standards require the surgical team to perform a formal Fire Risk Assessment during the Universal Protocol Time-Out prior to every surgical incision. A validated 3-factor screening scoring system assigns 1 point for each present risk factor:

1. Surgical site above the xiphoid process (head, neck, face, upper chest)?
2. Open oxygen source being administered (nasal cannula, face mask, blow-by)?
3. Available ignition source present (electrosurgery, laser, electrocautery, light source)?

Immediate Fire Extinguishment Protocols

When a fire occurs in the operating room, immediate actions depend on the anatomical location: an Airway/Breathing Circuit Fire versus a Surgical Field/Patient Fire.

Protocol 1: Airway or Breathing Circuit Fire

An airway fire inside an endotracheal tube is an extreme surgical emergency requiring instantaneous, sequential actions:

┌────────────────────────────────────────────────────────────────────────┐
│                 AIRWAY FIRE IMMEDIATE ACTION PROTOCOL                  │
├────────────────────────────────────────────────────────────────────────┤
│ 1. DISCONNECT BREATHING CIRCUIT FROM ETT                               │
│    ↳ Instantly halts oxidizer (O2 and N2O) flow to the flames.         │
│                                                                        │
│ 2. EXTUBATE THE TRACHEA IMMEDIATELY                                    │
│    ↳ Removes the burning fuel source from the patient's airway.        │
│                                                                        │
│ 3. EXTINGUISH BURNING TUBE & TISSUE WITH STERILE WATER / SALINE        │
│    ↳ Douse burning tube on the field and flush remaining embers.       │
│                                                                        │
│ 4. VENTILATE BY MASK WITH ROOM AIR / AIR WASH                          │
│    ↳ Avoid 100% O2 initially to prevent reignition of smoldering tissue│
│                                                                        │
│ 5. RE-INTUBATE TRACHEA ONCE FIRE IS EXTINGUISHED                       │
│    ↳ Secure airway before acute glottic and laryngeal edema develops.  │
│                                                                        │
│ 6. PERFORM IMMEDIATE BRONCHOSCOPY                                      │
│    ↳ Inspect tracheobronchial tree for thermal injury and soot/char.   │
└────────────────────────────────────────────────────────────────────────┘

Protocol 2: Surgical Field, Patient, or Drape Fire

1. Immediately remove burning drapes and towels from the patient onto the operating room floor. Do not pat flames down on the patient, as this drives heat into tissues.
2. Smother flames with wet towels or douse with sterile water/saline from the back table basins.
3. Halt medical gas flows: Shut off oxygen and nitrous oxide flows at the anesthesia machine flowmeters or room zone shut-off valves if the fire is uncontrolled.
4. Assess patient injury: Inspect skin and wound bed for thermal/chemical burns, initiate burn dressings, and evaluate vital signs.
5. Preserve evidence: Quarantine all implicated equipment, ESU pencils, lasers, drapes, and gas lines for root cause analysis (RCA), bioengineering inspection, and regulatory incident reporting.

Facility Fire Response: RACE & PASS

For fires that extend beyond the immediate surgical field, staff must execute facility-wide fire safety protocols:

• RACE:
  • R - Rescue / Remove: Remove patients and personnel from immediate danger.
  • A - Alarm: Pull the manual fire alarm pull station; announce emergency code (Code Red).
  • C - Confine / Contain: Close all doors to operating rooms and patient bays to isolate smoke and flames.
  • E - Extinguish / Evacuate: Use portable fire extinguishers or execute evacuation.
• PASS (Fire Extinguisher Operation):
  • P - Pull the safety locking pin.
  • A - Aim the nozzle at the base of the fire.
  • S - Squeeze the carrying handle/trigger levers.
  • S - Sweep nozzle side-to-side across the base of the flame.
• Extinguisher Types in the OR: Class A/B/C Carbon Dioxide (CO₂) or Water Mist extinguishers are preferred in operating suites. Dry chemical extinguishers discharge caustic monoammonium phosphate powders that corrode precision medical electronics and inflict severe chemical trauma to exposed patient tissues and open wounds.

Intraoperative Code Blue & Cardiac Arrest in the ASC

Cardiac arrest in a freestanding ASC requires immediate, disciplined execution of Advanced Cardiovascular Life Support (ACLS) by the perioperative team.

Immediate Resuscitation Priorities

1. Recognition & Chest Compressions: Confirm unresponsiveness and absence of carotid pulse (<10 seconds). Initiate high-quality chest compressions immediately: rate of 100 to 120 compressions/min, compression depth of 2 to 2.4 inches (5 to 6 cm), allowing complete chest recoil, and minimizing interruptions to <10 seconds. Place the backboard under the patient immediately.
2. Defibrillation within 2 Minutes: Attach AED or manual defibrillator pads without interrupting compressions. For shockable rhythms (Ventricular Fibrillation [VF] or Pulseless Ventricular Tachycardia [pVT]), deliver an immediate biphasic shock (120 to 200 Joules) and resume compressions instantly for 2 continuous minutes before re-checking rhythm.
3. Airway & Oxygenation: The anesthesia provider secures the airway with an endotracheal tube, ventilating with 100% oxygen at 10 breaths/min (one breath every 6 seconds) synchronous with continuous compressions.
4. Pharmacotherapy: Administer Epinephrine 1 mg IV/IO every 3 to 5 minutes. For shockable rhythms refractory to defibrillation, administer Amiodarone (300 mg IV initial bolus, followed by 150 mg second dose) or Lidocaine (1.0–1.5 mg/kg IV). (CRITICAL EXCEPTION: If arrest is suspected secondary to Local Anesthetic Systemic Toxicity [LAST], administer 20% lipid emulsion, reduce epinephrine to ≤1 mcg/kg, and strictly avoid lidocaine!).

Systematic Screening of Reversible Causes: The 5 H's and 5 T's

Emergency Transfer of Care & Facility Evacuation

Freestanding ASCs operate under federal CMS Conditions for Coverage (42 CFR §416.44), state licensing regulations, and accreditation standards (AAAHC, The Joint Commission) that require formal emergency transfer infrastructure.

Hospital Transfer Protocols

CMS requires an effective procedure for immediate transfer when a patient needs emergency hospital care, plus initial and periodic written notice of ASC operations and patient population to a local hospital. Current federal requirements do not make a written transfer agreement or universal physician admitting privileges the alternative prerequisites stated in older guidance. State, accreditation or facility requirements may add obligations.

Activate EMS early for a life-threatening condition, continue stabilization within capability, and send an organized clinical record. The handoff includes identifiers, procedure and anesthesia, event timeline, assessment, allergies, medications and fluids, airway status, vital-sign trends, laboratory or imaging results, devices, and interventions and response. Document the decision, notifications, departure, receiving destination and personnel accompanying the patient.

Facility Evacuation Priority & Pathways

When a structural fire, catastrophic utility failure, or active threat mandates facility evacuation, perioperative personnel must execute systematic evacuation protocols:
