Cause of death

hypoxic ischaemic brain injury complicating acute asthma

AI-generated summary

A 57-year-old man with asthma and hay fever died from hypoxic ischaemic brain injury following an acute asthma exacerbation during Melbourne's November 2016 thunderstorm asthma event. The deceased was outdoors during the thunderstorm, became acutely breathless around 6:15pm, and his family called for an ambulance at 6:20pm. While family-administered CPR continued for ~23 minutes before paramedic arrival, the short timeframe from symptom onset to respiratory arrest (estimated 15 minutes) made survival unlikely. Post-mortem testing revealed extreme sensitisation to ryegrass pollen. Key clinical lessons include the need for better asthma management, preventer medication use, allergy testing, asthma action plans, and remaining indoors during high-risk TA warnings. The case illustrates system-level challenges during mass-casualty events and opportunities for improved community health literacy regarding hay fever-asthma links.

Contributing factors

  • thunderstorm asthma event
  • severe allergic sensitisation to ryegrass pollen
  • hay fever with seasonal asthma exacerbations
  • sub-optimal preventer medication use
  • lack of asthma management plan
  • exposure to environmental trigger during thunderstorm
  • rapid onset of severe bronchospasm (estimated 15 minutes to respiratory arrest)

Coroner's recommendations

  1. Continue further research into meteorological, biological and aerobiological factors contributing to thunderstorm asthma events to improve forecasting accuracy
  2. Further verification and development of the thunderstorm asthma forecasting system
  3. Continue public awareness campaigns by DHHS regarding thunderstorm asthma, asthma action plans, and hay fever-asthma links
  4. Encourage hay fever sufferers to undergo allergy testing to better understand susceptibility and inform management
  5. Develop specific management plans for those at risk in anticipation of seasonal exacerbations or thunderstorm asthma
  6. When thunderstorm asthma warnings are issued, advise at-risk individuals to remain indoors with windows and doors closed, turn off evaporative cooling systems, and consider altered travel times
  7. Continue work on providing more specific and accurate information to emergency services callers regarding estimated ambulance arrival times
