Description of intervention(s) / exposure
Comparision of standard intramuscular adrenaline (0.01 mg/kg to a maximum of 0.5 mg - repeated once at 5-10 minutes as required) vs. intravenous infusion (1:100,000) titrated to effect (starting at 0.5 mls/kg/hr or 1.0 mls/kg/hr if hypotensive) in the initial management of patients with ananphylaxis

Outcomes
Primary outcome [1] 262323 0
The primary clinical endpoint will be resolution of main clinical features (defined by absence of the feature or improvement by at least 2 points on the ordinal severity scale) at 15 minutes.
Timepoint [1] 262323 0
15 minutes
Secondary outcome [1] 273542 0
The two groups will be compared for adverse effects such as myocardial ischaemia, myocardial infarction, hypertension and intracerebral haemorrhage. This will assessed via direct questioning, clinical assessment and continuous monitoring of ECG and Blood pressure
Timepoint [1] 273542 0
15 and 60 minutes

Summary
Brief summary
Anaphylaxis is a severe potentially life-threatening allergic reaction. The accepted management is intramuscular adrenaline. With intravenous adrenaline being a last resort therapy. The investigators believe that intravenous adrenaline given slowly as a dilute infusion is a better therapy, with more rapid onset (especially in patients with low blood pressure) with a similar side-effect profile to intramuscular adrenaline. This study is part of a wider PhD assessing this hypothesis and also the pharmacological behaviour of adrenaline.
