What Are Common Sources Of Heat In The Operating Room?

What type of fire extinguisher is used in the operating room?

The typical water-mist fire extinguisher is rated for Class A and Class C fires; both of which are possible in an operating room.

But what about Class B fires.

Most operating rooms are known to have flammable liquids, and a Class B fire extinguisher would be required..

What is the most common location for a patient fire in the operating room?

2 Surgical fires involved electrosurgical equipment 68% of the time. The most common sites of fires were the head, face, neck, and upper chest. Supplemental oxygen was also present in most cases.

Where do most surgical fires occur?

Surgical fires most often occur in surgeries performed on the head, neck, and chest, because the electrosurgical equipment, or the ignition source, comes within a close proximity of the oxygen being given to the patient. Injuries from these fires often occur on the head, face, and chest.

How do patients keep warm during surgery?

What is forced-air warming? Forced-air warming is typically delivered via a special blanket or a gown that’s placed on or under the patient throughout the surgical process.

How can surgical fires be prevented?

Recommendations to Reduce Surgical Fires:A fire risk assessment at the beginning of each surgical procedure. … Encourage communication among surgical team members. … Safe use and administration of oxidizers. … Safe use of any devices that may serve as an ignition source. … Safe use of surgical suite items that may serve as a fuel source.More items…•

Why are fire blankets not used in the OR?

Of importance, fire blankets should not be used in the operating room since they can concentrate both heat and oxygen on the patient, potentially worsening the fire. Use of a fire extinguisher is exceedingly rare, but all operating suites are required to maintain them for use.

Why does oxygen cause fire?

Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.

How common are surgical fires?

Surgical fires are fires that occur in, on or around a patient undergoing a medical or surgical procedure. Surgical fires are rare but serious events. The ECRI Institute estimates that approximately 550 to 600 surgical fires occur each year.

Why is it so cold in the operating room?

The reason it’s so cold is due to the surgical lights in the room. They provide a lot of heat over the surgical table. Because the surgeon is in a mask, gloves, hat and gown and may be performing a surgical procedure that takes several hours, they need to make sure they are not over heated.

Do they add oxygen to operating rooms?

Air pressure is higher in surgery room, to prevent bacterias to enter the room, with higher pressure come more oxygen, but still the same part as outside (about 21%). There is no such thing as oxygen enrichment, and it would be very dangerous, anaesthesia gases are very flammable, and surgeons like to make sparks…

Can your heart catch on fire during surgery?

“While there are only a few documented cases of chest cavity fires — three involving thoracic surgery and three involving coronary bypass grafting — all have involved the presence of dry surgical packs, electrocautery, increased inspired oxygen concentrations, and patients with COPD or pre-existing lung disease,” …

Is nitrous oxide flammable anesthesia?

However, the administration of nitrous oxide and its subsequent diffusion into the intestinal lumen can create a flammable premixed fuel/oxygen mixture. The chance of such an explosion/fire is reduced if nitrous oxide is avoided.
