AORN Period safety Equipment Focus questions and answers latest 2023The fire triangle ignition source, oxidizers, fuel Potential sources of fuel for surgical fires - patient and staff linens and drapes - prep solutions - skin degreasers/ tinctures/ aerosols - body tissues and patient hair -intestinal gases Basic fire safety guidelines the perioperative nurse should be aware of include: -take the patients medical records if possible -have an evacuation plan posted in the surgical suite, and review it frequently -surgical patients who are evacuated due to a fire have an increased risk of post operative infection -move patients horizontally. if you cant move horizontally because smoke or flames block your way, proceed vertically. work your way down to a lower level -Never leave your patients unattended -Hold routine fire drills or mock scenerios involving all members of the surgical team Methods to prevent an unsafe situation, mishap, or fire when using electrosurgical equipment include: -do not use an oxygen-enriched enviornment, such as the trachea or when oxygen is being "blown over" a patient -allow enough time for skin prep solutions that are flammable or contain alcohol to thoroughly dry -visually check the integrity and insulation of all cords and coagulation instuments before use -inspect the ESU before use -periodically clean the active electrode tip during use to prevent tissue from coating the tip volatile liquid liquid that evaporates quickly. Usually in the OR they are: -skin antiseptic agents -anesthetic gases -specimen fixatives -lubricants What is the best way to reduce the risk associated with ignition of prep solution vapor? allow the prep solution to completely dry and for the vapors to dissipate BEFORE draping Over pressurization of tourniquet cuff may cause: -pain at tourniquet site -muscle weakness -compression injuries to blood vessels, nerve, muscle or skin -extremity paralysis Potential complications from the use of the pneumatic tourniquet include: -nerve injury -paralysis -skin blisters -necrosis -swelling -chemical burns Bier block technique of intravenous regional anesthesia (IVRA) involved an IV injection of local anesthetic agent into the vein of a tourniquet-occulded extremity and then use of a dual bladder cuff inflation times for a tourniquet upper extremities: 1 hr lower extremities: 1 & 1/2 hr - 2 hrs isolated power lines prevents unintentional grounding of persons in contact with a live electrical cable or current. Faulty grounding can result in a burn, cardiac fibrillation, or chock to the patient or user. Immediate actions a perioperative nurse can take when there are line isolation issues - if a line isolation monitor alarm sounds = staff member should unplug the last piece of equipment in the room that was plugged in - if the alarm still continues to sound- the members should begin unplugging unnecessary equipment in the room until the alarm stops -An OR member should notify facility management staff that the isolation alarm had been activated -The piece of equipment in question (the one unplugged that made the alarm stop) should be sent to biomedical maintenance for evaluation and repair.
