Article Synopsis
  • Anaphylaxis is a serious and potentially fatal allergic reaction; this study aimed to explore its frequency and the characteristics of biphasic reactions, which can occur in some patients after initial anaphylaxis.
  • The research analyzed data from 264,689 pediatric patients between 2010 and 2017, finding that 353 were hospitalized for anaphylaxis, with 6 of those cases (1.7%) exhibiting biphasic reactions.
  • The study highlighted the need for careful monitoring after anaphylaxis, as biphasic reactions occurred frequently, with a median onset time of around 5.9 hours after the initial reaction.
