It is unclear whether the NIAID/FAAN criteria or Brighton case
definition are valid for immediately diagnosing anaphylaxis due to the
very low certainty of evidence.
Adrenaline is the cornerstone of first-line emergency management of
anaphylaxis but, due to ethical constraints, little robust research has
assessed its effectiveness . Newer models of adrenaline autoinjectors
may slightly increase the proportion of people correctly using the
devices and reduce time to administration.
Face-to-face training for laypeople may slightly improve anaphylaxis
knowledge and competence in using autoinjectors.
Adrenaline prophylaxis prior to snake bite anti-venom may reduce
anaphylaxis but the impact of prophylactic corticosteroids and
antihistamines is uncertain.
There was insufficient evidence about the impact of other anaphylaxis
management strategies.
