Smoke Inhalation with Dr. Lane
Selena L. Lane, DVM, DACVECC, University of Georgia
In this episode, host Alyssa Watson, DVM, talks with Selena Lane, DVM, DACVECC, about her recent Clinician’s Brief article, “Smoke Inhalation.” Dr. Lane explains what exactly causes the problems in these pets and how to assess them with a focus on respiratory injury and toxins like carbon monoxide or hydrogen cyanide. She also shares the best therapeutic approaches for these dynamic cases.
The 5 most common clinical consequences are: acute upper airway obstruction, bronchospasm, small airway occlusion, pulmonary infections, and respiratory failure.
Once inhaled, soot adheres to the mucosa in the trachea and begins to disrupt natural defense mechanisms causing the airway to become less effective at clearing out debris. It also allows bacteria and other irritants to bind to the mucosa.
The 2 most common toxic gasses seen in house fires are carbon monoxide and hydrogen cyanide. Carbon monoxide can bind up the hemoglobin making patients functionally anemic—though they are not actually anemic as they have the same number of red blood cells.
Airway damage can be delayed. Continue to monitor for at least 24 hours, ideally up to 72 depending on the patient.
Arterial blood gas measurement is a practical and reliable method of measuring hypoxemia. A pulse ox will be inaccurate.
Do not overdo it with fluids. Edema is already occurring.
Avoid NSAIDs or steroids in most smoke inhalation patients.
