| Abstrakt: | The definition of a surgical fire is one that occurs in, on, or around a patient undergoing a surgical procedure. Urologists, as with all surgeons, utilize and bring the components of the fire triangle into proximity, increasing the risk of a surgical fire. Three main components of the fire triangle are required for a surgical fire to take place: fuel source, oxidizer, and an ignition source.[1] The first component is a fuel source. Common fuel sources include degreasers, prepping agents, drapes, towels, sponges, dressings, tapes, gowns, hoods, masks, ointments, benzoin, aerosols, alcohol, mattress, pillows, blankets, ECG electrodes, hoses, tissue, GI gases.[2] The second component is an oxidizer. Common oxidizers are room air, oxygen, nitrous oxide.[2] Lastly, the third necessary component is an ignition source. Common ignition sources include a light source, laser, electrocautery, sparks from high-speed drills and burrs, defibrillators, glowing embers of charred tissue, flexible endoscopes, tourniquet cuffs.[2] Sources of each of these three components are often present close to the patient in the medical setting or operative suite. A further risk factor for surgical fires is a high oxidizer level or elevated oxygen concentration greater than the normal atmospheric oxygen level of 21%. This risk is particularly high during head and neck, oral pharyngeal, and rectal surgeries, where higher oxygen levels or methane gas may be present.[3] Oxidizer levels cause a decrease in the ignition point temperature of fuels. Curiously enough, inhaled halogenated anesthetics are similar to halogenated fire extinguishing agents and are considered non-flammable and may actually be protective of endotracheal tube fires.[4] Nonetheless, the Emergency Care Research Institute (ECRI) has ranked surgical fires in their top ten technological hospital hazards to patients.[2] (Copyright © 2022, StatPearls Publishing LLC.) |
