[Anaphylactic accidents. Etiologic and clinical study of 143 cases outside the hospital setting]

From 01/01/1981 to 31/12/1986 inclusive, the S.A.M.U. of Lyon investigated 143 anaphylactic accidents in an extra-hospital environment. The allergological study has shown that 36.3% of the patients are already the victims of a similar incident (in 9.8% of cases, with the same product). The main causative products are the analgesics and non-steroid anti-inflammatory compounds, hymenoptera venoms and antibiotics. In about 1 in 4 cases the enquiry gave negative results. In 1 case in 2 there was a cardiovascular collapse; however it was not possible to establish the relationship between the severity of the clinical picture and the different classes of products. There were no deaths. In comparison with preceding studies there were no developments in the place occupied by the causative products.
