Hydroxocobalamin Administration After Inhalation Injury Is Not Associated With Mesenteric Ischemia.
Hydroxocobalamin has been administered in the United States since 2006 by first responders and burn centers as a safe antidote for cyanide toxicity, a serious complication of smoke inhalation. There are no current contraindications to the use of this rescue measure. A recent retrospective French publication reported a potential correlation between hydroxcobalamin administration and acute mesenteric ischemia (AMI) in critically ill burn and inhalation injury patients. ⋯ Eighty-two percent of those with bronchoscopy had an inhalation grade of 2 or greater. None (0%) of the patients showed signs of mesenteric ischemia, tube feeding intolerance, pneumatosis/perforation on CT, or necrotic bowel on laparotomy. Aware of the study limitations, we conclude that hydroxocobalamin does not increase risk for AMI.
