Hypoxic encephalopathy secondary to cardiac arrest due to cardiomegaly
AI-generated summary
Robert John Viner, a 58-year-old man with long-standing schizoaffective disorder, was detained under the Mental Health Act on 28 July 2006 following erratic behaviour and aggression towards family and his GP. He was admitted to Flinders Medical Centre's Emergency Department at 5pm. He received Olanzapine 5mg at 5:10pm and Clonazepam 1mg at 7:50pm and again at 12:58am. He suffered a cardiac arrest at approximately 5:25am on 29 July 2006. Post-mortem examination revealed cardiomegaly as the underlying cause. He was resuscitated but suffered severe hypoxic encephalopathy and was extubated on 30 July 2006, dying at 6:40pm. The coroner found his treatment appropriate with no suspicious circumstances. The underlying cardiac pathology (cardiomegaly) appears to have been undetected pre-arrest; cardiovascular assessment on admission may have identified this risk.
