Two patients experienced airway obstruction from supraglottic swelling. Causes included a brown spider bite (loxoscelism) and consuming buffalo fish, possibly due to scrombroid or anaphylactic reactions.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Otolaryngology

Background:

  • Airway obstruction is a critical condition requiring prompt diagnosis.
  • Supraglottic swelling can lead to severe respiratory distress.

Observation:

  • Case 1: A patient developed supraglottic swelling and airway obstruction following a brown spider bite on the ear, consistent with loxoscelism.
  • Case 2: Another patient presented with airway obstruction due to supraglottic swelling after consuming buffalo fish, suspected to be scrombroid poisoning or anaphylaxis.

Findings:

  • Brown spider bites can induce severe local and systemic reactions, including airway compromise.
  • Ingestion of certain fish species can trigger histamine-mediated (scrombroid) or IgE-mediated (anaphylactic) reactions causing supraglottic edema.

Implications:

  • Highlights the diverse and potentially life-threatening causes of supraglottic swelling.
  • Emphasizes the importance of considering environmental and dietary exposures in the differential diagnosis of airway obstruction.
  • Underscores the need for rapid assessment and management of patients with acute upper airway compromise.
