Epidemiology and Outcome of Anaphylactic Shocks Admitted to Intensive Care Unit
Epidemiology and Outcome of Anaphylactic Shocks Admitted to Intensive Care Unit
Anaphylaxis is a severe life-threatening reaction following exposure to an antigen. Its
 incidence is progressively increasing in the general population over years, accompanied with
 an increased number of hospitalizations. Although rare, this condition is often associated
 with a significant morbidity and mortality. The mortality rate has been recently estimated at
 0.84 (95% CI, 0.79 to 0.88) per million per year in the French adult population. Age, chronic
 medication and cardiac or pulmonary comorbidities have been reported to increase the risk of
 a severe reaction. Obesity, age and cardiovascular comorbidities have been identified as risk
 factors for fatal anaphylaxis. However, the risk factors for death after ICU admission have
 not been elucidated yet.
