Epinephrine is a first-line drug for anaphylaxis, but a poor prognosis can occur if not administered properly. This study compared the clinical features of patients with anaphylaxis in the emergency department (ED) according to epinephrine administration.
This was a retrospective cross-sectional study using ED-based data retrieved from a tertiary university hospital. Patients diagnosed with anaphylaxis between 2018 and 2020 were enrolled in this study. The patients with anaphylaxis were classified according to epinephrine administration, and the clinical features were compared. The adjusted odds ratios (AORs) with a 95% confidence interval (CI) were calculated for the main factors associated with epinephrine use.
Among 205 eligible patients with anaphylaxis, 157 (76.6%) were treated with epinephrine. The main contributing factors influencing epinephrine use were patients with cardiovascular symptoms (AOR=2.97; 95% CI, 1.26-7.01) and patients transferred from other hospitals (AOR=0.37; 95% CI, 0.16-0.85).
The major factors influencing epinephrine use in the ED when patients with anaphylaxis presented with cardiovascular symptoms were identified. It is essential to prevent potentially fatal consequences in patients with anaphylaxis through appropriate epinephrine administration.
