[A case of anaphylactic shock by multiple causes].

We experienced anaphylactic shock after introduction of the general anesthesia twice in the same patient. After the first incidence of anaphylactic shock, we judged that the allergen was a latex. For the second time we planned the latex free environment, but the anaphylactic shock occurred again. As a result of the investigation, it turned out that the allergens were due to latex and sevoflurane. After the first incidence, it was necessary to retrieve the antigen from all the agents used. When we encounter the anaphylactic shock, it is necessary to examine all the medicines, and should have two or more suspectible medicines in mind.
