Answer

Most patients with anaphylaxis may be treated successfully in the ED and then discharged. Treatment success operationally may be defined as complete resolution of symptoms followed by a short period of observation. The purpose of observation is to monitor for recurrence of symptoms (ie, biphasic anaphylaxis). An observation period of 10 hours appears sufficient for most reactions, but some investigators recommend 24 hours. [77]
