An automatic alert will be sent at 6 months to review the case notes; log in and record if allergen testing is positive for any components of the regional anaesthesia technique usedDid the patient develop life threatening anaphylaxis with: 1. Unexpected severe hypotension AND/OR 2. Severe bronchospasm AND/OR Swelling with actual or potential airway compromise OR 4. Cardiac arrest?(Required) Yes No Was the anaphylaxis confirmed to be secondary to: 1. Local anaesthetic in RA technique OR 2. Another drug administered during central neuraxial or peripheral nerve block OR 3. Skin preparation solutions for RA performance?(Required) Yes No Was anaphylaxis confirmed by allergen testing to be secondary to any drug used for sedation or general anaesthesia in a patient (who had a concurrent central neuraxial or peripheral nerve block)?(Required) Yes No Unsure Was the anaphylaxis agreed by the local multidisciplinary team to be secondary to another cause unrelated to the peripheral nerve block?(Required) Yes No Unsure Sorry, this case is not eligible to report.

Yes No Already intubated Was blood taken for mast cell tryptase? Yes No Please provide mast cell resultsWas the patient referred to an allergy clinic? Yes No TimelinePlease prepare a timeline detailing each drug, fluid, blood product and sterilisation agent administered in the 120 minutes prior to anaphylaxis developing. Please use the first direct procedural contact by the anaesthetist or PAA as TIME ZERO (e.g. either induction of general anaesthesia or commencement of a regional anaesthetic technique) and label this as such. Please consider and include where appropriate all the following agents (doses are not required). Skin cleansing agent for block All local anaesthetics and additives used for regional anaesthetic or surgical local infiltration Pre-medication Induction agent Opioids Other multimodal analgesics Muscle relaxant Anti-emetic Volatile agent Antimicrobial Reversal agent IV colloid Blood products Dye Skin cleansing agent for surgical procedure Please finish by documenting the time of the anaphylaxis in relation to time zero ListTime (start 00:00)EventProduct administeredRoute given Add Remove
