title: Prolonged cardiovascular collapse due to unrecognized latex anaphylaxis.
abstract: We present a case of a prolonged anaphylactic reaction that occurred in temporal relationship to the administration of cefazolin. Subsequent allergy testing was positive for latex and negative for cefazolin-both unexpected results. Our case illustrates that medications administered before the onset of anaphylaxis should not be assumed to be the causative allergen and that a latex allergy should be considered in the differential diagnosis. Because the etiology of an anaphylactic reaction cannot be immediately determined, patients experiencing intraoperative cardiovascular collapse should be treated in a latex-free environment.
  
  
  CONCLUSIONS
  We describe a patient who experienced latex-induced intraoperative anaphylaxis. The event coincided with antibiotic administration, which prompted us to erroneously assume that the causative allergen was medication related. Allergy to latex must always be considered as a potential culprit of perioperative cardiovascular collapse.
