BACKGROUND: The aim of this study was to investigate the clinical characteristics of anaphylactic shock and the factors associated with anaphylactic shock in @entity2021 . METHODS: Data were retrospectively collected from @entity1 with @entity2021 for 10 years. Study subjects were searched with @entity66 codes including anaphyla-, adverse, @entity113 , @entity566 , insect bite, @entity5157 , and @entity56 to prevent omission. All the 294 study subjects were divided into shock and nonshock groups. RESULTS: The mean age of the subjects was 43 years old, and males comprised 162 @entity1 (55%). There were 119 @entity1 (41%) in the shock group and 175 @entity1 in the nonshock group. Age was older in the shock group than in the nonshock group; however, there was no difference in sex between 2 groups. Frequent causes of @entity2021 were drugs in the shock group and food in the nonshock group. Nonsteroidal anti-inflammatory drugs and radiocontrast media were the most common cause of drug-induced @entity2021 in the nonshock group and shock group, respectively. @entity65 were the most frequent symptoms in the shock group. Factors associated with the shock in cases with @entity2021 were old age, @entity341 ( @entity341 ) arrival by emergency medical services use, radiocontrast material, symptoms with @entity848 , @entity1163 , and @entity1296 . CONCLUSION: Elderly anaphylactic @entity1 with symptoms of @entity848 , @entity1163 , and @entity1296 were at increased risk for the development of shock. Physicians in the @entity341 have to be alert to the possibility of progression to shock in @entity1 with @entity2021 , and early recognition of anaphylactic shock is critical for adequate treatment.
