Treatment for Battery Fire Inhalation

Initial Management

Assess for signs of airway obstruction including voice modification, stridor, and laryngeal dyspnea, and monitor oxygen saturation, providing supplemental oxygen as needed, according to the American Society of Anesthesiologists 1
Monitor oxygen saturation and provide supplemental oxygen as needed, following the guidelines of the American Society of Anesthesiologists 2
Look for signs of smoke inhalation: soot on face, dysphonia, dyspnea, wheezing, and/or blackish sputum, as recommended by the American Society of Anesthesiologists 3

Perform immediate intubation if the patient shows severe hypoxia or hypercapnia, altered mental status/coma, or signs of airway obstruction, as advised by the American Society of Anesthesiologists 1
Perform immediate intubation if the patient shows severe respiratory distress, severe hypoxia or hypercapnia, as recommended by the American Society of Anesthesiologists 2
For patients without immediate indications for intubation, closely monitor and regularly reassess the airway status as edema may develop progressively, according to the American Society of Anesthesiologists 1

If airway fire occurred, remove any burning materials from the airway, pour saline or water into the patient's airway to extinguish residual embers and cool tissues, and consider bronchoscopy to assess injury and remove debris, as recommended by the American Society of Anesthesiologists (ASA) 4
If airway fire occurred, pour saline or water into the patient's airway to extinguish residual embers and cool tissues, following the guidelines of the American Society of Anesthesiologists (ASA) 5
For external burns, remove all burning and flammable materials from the patient, extinguish all burning materials with saline, water, or smothering, as advised by the American Society of Anesthesiologists (ASA) 4

Perform bronchoscopy at a burn center to assess the severity of inhalation injury, as recommended by the American Society of Anesthesiologists 2
Monitor for delayed complications, including progressive airway edema, as advised by the American Society of Anesthesiologists 1

Consider hydroxocobalamin only if there is high suspicion of cyanide poisoning or elevated lactate levels, as recommended by the American Society of Anesthesiologists 3

Transfer to a burn center for definitive management, as advised by the American Society of Anesthesiologists 2

Delaying intubation when signs of airway compromise are present, as warned by the American Society of Anesthesiologists 1
Performing bronchoscopy in the field which may delay transfer to a burn center, as cautioned by the American Society of Anesthesiologists 2

Patients presenting with signs of inhalation injury, such as soot around the mouth and singed nasal hairs, indicate exposure to superheated gases and particulate matter, and warrant immediate diagnostic evaluation, according to the British Journal of Anaesthesia 6, 7
The presence of these clinical signs, although lacking sensitivity as predictors for intubation requirement, necessitate direct visualization of the airway to grade the severity of thermal injury and determine the extent of mucosal damage 7

After bronchoscopy, patients require close monitoring in a high-dependency area with regular reassessment for progressive airway edema 7
Patients should be positioned head-up and maintained nil-by-mouth if managed conservatively, with supplemental oxygen as needed and continuous oxygen saturation monitoring 7
Immediate intubation is necessary if signs of airway obstruction develop, such as dyspnea, desaturation, or stridor 7
Underestimating the risk of progressive airway edema, which can develop hours after initial presentation, is a common pitfall to avoid 7
