AI-generated summary
Michael Nelson, 62, died at Westmead Hospital on 3 May 2014 with multiple comorbidities including early-onset dementia, Parkinson's disease, neck dystonia (torticollis), and undernourishment. He presented to ED with inability to eat or lift his head. During acute agitation management, he was mistakenly given 2.5mg midazolam intravenously instead of intramuscularly due to miscommunication between Dr C. and RN Louise Copeland. Although the dose was within recommended limits, Mr Nelson developed respiratory depression and initial respiratory arrest, though he resumed breathing after CPR was ceased. He died approximately 4 hours later. The coroner found the IV midazolam was unusual and unpredictable rather than the direct cause of death. Key clinical lessons: ensure unambiguous communication about medication routes, particularly with benzodiazepines in elderly/frail patients; be alert to respiratory depression risks with IV midazolam in vulnerable populations; maintain clear prescribing and verification protocols during chaotic ED situations.
