7.3 Environmental Controls, Emergencies, and Cultural Competence

Environmental Controls, Emergencies, and Cultural Competence

The CSFA content outline section II.A (Administrative and Personnel, 6 items) includes environmental controls, resuscitation, All Hazards emergency protocols, safety hazard recognition, and culturally and socially competent strategies. These are distinct from the legal/ethical (7.1) and team communication (7.2) topics and require dedicated knowledge.

Operating Room Environmental Controls

The physical environment of the operating room is regulated by the AIA (American Institute of Architects) Facility Guidelines Institute (FGI) and ASHRAE Standard 170.

Air Quality.

• Total air exchanges: minimum 20 per hour in the operating room.
• Fresh (outdoor) air: minimum 4 of the 20 exchanges.
• Air pressure: positive relative to surrounding corridors (prevents influx of contaminated air).
• Airflow: laminar (unidirectional) for orthopedic and transplant rooms; mixed-flow for general surgery.
• Humidity: 30-60% (low humidity increases electrostatic discharge risk; high humidity promotes bacterial growth).
• Temperature: 68-73°F (20-23°C) for staff comfort and patient safety (hypothermia prevention requires active warming, not raising room temperature).

Monitoring. The CSFA must be able to identify when the room environmental indicators (displayed on the OR control panel) fall outside parameters and report to the facility engineer. Air pressure loss during a case requires immediate notification of the surgeon and infection prevention.

Resuscitation in the OR

Intraoperative cardiac arrest may be caused by:

• Massive blood loss (hemorrhagic shock).
• Malignant hyperthermia (in susceptible patients exposed to succinylcholine or volatile anesthetics).
• Local anesthetic systemic toxicity (LAST).
• Anaphylaxis (latex, contrast, antibiotics, neuromuscular blockers).
• Pulmonary embolism (fat, air, or clot).
• Vagal response (e.g., traction on viscera).

The CSFA's Role in a Code.

• Stop the surgical stimulus if possible.
• Provide exposure for chest compressions (if surgical field allows).
• Prepare the defibrillator pads and ensure gel is applied.
• Have epinephrine, atropine, and the MH kit (dantrolene 2.5 mg/kg initial dose) ready.
• Document the time of arrest, time of first compression, time of defibrillation, and medications given.
• Activate the massive transfusion protocol for hemorrhage-related arrest.
• Switch to a crash cart if needed.

AHA BLS/ACLS Algorithm. The CSFA should maintain current BLS certification. The algorithm for the surgical patient includes:

1. Confirm no pulse (carotid, femoral).
2. Begin high-quality CPR (100-120 compressions/min, 2 inches depth, full recoil).
3. Defibrillate as soon as possible for shockable rhythms (VF, pulseless VT).
4. Administer epinephrine 1 mg every 3-5 minutes.
5. Consider reversible causes (H's and T's): Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hypo-/Hyperkalemia, Hypothermia, Tension pneumothorax, Tamponade, Toxins, Thrombosis (PE or MI).

All Hazards Emergency Protocols

All Hazards is a framework for emergency preparedness that covers multiple scenarios with a common response structure.

OR Fire (Surgical Fire Triangle).

• Heat (ignition) source: electrosurgery, laser, fiberoptic light cord.
• Fuel: drapes, gowns, gauze, alcohol prep, hair, GI tract gas (methane).
• Oxidizer: room air, supplemental O2, N2O.

Fire prevention requires removing one element. For head and neck cases with supplemental oxygen, use a cuffed endotracheal tube, tent the drapes to avoid O2 pooling, and do not use alcohol-based prep near the airway.

If a Fire Occurs:

1. Stop the flow of airway gases (turn off O2 and N2O).
2. Remove the burning drapes.
3. Extinguish with saline.
4. Assess the patient's airway and breathing.
5. Rescue the patient, then alarm, then extinguish if possible.

Chemical Spill. Common hazardous chemicals in the OR include glutaraldehyde (Cidex), high-level disinfectants, and formaldehyde. The CSFA must know the location of the spill kit, use the SDS (Safety Data Sheet) for the chemical, and wear appropriate PPE (nitrile gloves, face shield, gown).

Radiation Exposure. Fluoroscopy is the most common source of radiation in the OR. ALARA (As Low As Reasonably Achievable) principles apply:

• Wear a lead apron (0.25-0.5 mm lead equivalent) and thyroid shield.
• Stand as far as possible from the C-arm (inverse square law: doubling distance reduces exposure 4-fold).
• Use the collimation and last-image-hold features.
• Wear a dosimeter badge under the lead apron.

Power Failure. The OR must have backup generators that activate within 10 seconds. The CSFA must know the location of battery-powered lights and the manual override for the OR table.

Mass Casualty / Disaster. The CSFA must know the facility's incident command structure and where the CSFA is assigned in the disaster plan. Most surgical technologists and first assistants are deployed to the OR for emergent trauma cases.

Active Shooter (Run, Hide, Fight). The CSFA must follow the facility's protocol. For the OR specifically, the patient cannot easily run; hiding in a locked OR and defending the patient are common protocols.

Safety and Environmental Hazards

Laser Safety.

• Wavelength-specific eyewear for all personnel in the room.
• Laser-safe endotracheal tube (foil-wrapped or specifically manufactured).
• Water-based rather than alcohol-based prep.
• Wet towels around the surgical site to absorb stray beam energy.
• Warning sign on the OR door with the laser type and required eyewear.
• Laser activation announced verbally ("Laser on") before each use.

Surgical Plume. Electrosurgery and laser generate a plume of vaporized tissue that contains particulate matter and potentially viable cells. The CSFA must ensure the smoke evacuator or in-line filter is used. Long-term exposure to surgical plume has been associated with respiratory symptoms and possible carcinogenic risk.

Tourniquet Safety. Tourniquet time is limited to 2 hours for the lower extremity and 1.5 hours for the upper extremity. Pressure is typically 250-300 mmHg for the leg and 200-250 mmHg for the arm. The CSFA must document the tourniquet time and pressure, and release the tourniquet before the 2-hour limit.

Culturally and Socially Competent Care

The CSFA cares for patients of diverse cultural, religious, and social backgrounds. Cultural competence is the ability to provide care that respects the patient's values, beliefs, and practices.

Religious and Cultural Practices.

• Jehovah's Witness: Refusal of whole blood, packed RBCs, platelets, and plasma. The CSFA must be prepared for bloodless surgery (cell saver, acute normovolemic hemodilution, antifibrinolytics like tranexamic acid).
• Muslim patients: Modesty is a priority; same-gender caregivers when possible; the surgical site should be exposed only as needed and re-draped immediately.
• Orthodox Jewish patients: Sabbath observance (surgery is permitted only if life-threatening on the Sabbath); a rabbi may be consulted for non-emergent decisions.
• Hindu patients: May refuse bovine-derived products; the CSFA must verify the source of biological mesh or suture material.

Language and Communication.

• Use a trained medical interpreter for consent and care communication, not a family member (family members may filter, summarize, or alter information).
• Confirm the patient's understanding with teach-back: ask the patient to repeat the consent information in their own words.
• Document the interpreter's name and ID on the consent form.

Socially Competent Strategies.

• Address the patient by their preferred name and pronoun.
• Recognize the role of family and community in decision-making in many cultures.
• Avoid assumptions based on appearance; ask the patient directly about their preferences and concerns.
• Acknowledge implicit bias and its potential effect on care.

Cultural Competence Checklist for the CSFA

Surgical Trap: A patient who appears to speak English may not have adequate health literacy to give informed consent for a complex procedure. The CSFA must always use a trained interpreter for consent in patients whose primary language is not English, even if the patient appears to converse in English, because medical-legal consent requires the patient to understand the risks, benefits, and alternatives in their primary language.
