Raymond cho findings

Male·Hypoxic brain injury secondary to anaphylaxis caused by walnut ingestion

Raymond Cho, a secondary school student with a known walnut allergy, died of hypoxic brain injury following anaphylaxis at Royal Prince Alfred Hospital on 24 May 2011. He suffered anaphylaxis after ingesting walnuts, likely at school, resulting in brain damage and death. The coroner found the death preventable through better emergency response systems. Key systemic failures included inadequate access to auto-injectors for at-risk students, insufficient staff training in anaphylaxis recognition and treatment, and unclear instructions on auto-injector use. Recommendations focused on ensuring students carry their own medications, improving face-to-face staff training on anaphylaxis, enhancing action plans, and restricting nuts in schools.
