Coroner's Finding: SMITH Norman Ebanezer John

54y · Male·Respiratory failure due to aspiration pneumonia and acute autonomic and sensory neuropathy complicating hyponatraemia

Norman Ebanezer John Smith, aged 54, a long-term psychiatric patient under guardianship, died of respiratory failure due to aspiration pneumonia and acute neuropathy complicating severe hyponatraemia (sodium 109). He presented with seizure on 30 March 2010, requiring ICU admission. Despite treatment with hypertonic saline and antibiotics, he deteriorated with pulmonary oedema and progressive neurological decline. The coroner found his treatment generally appropriate but noted two concerns: poorly controlled diabetes at Glenside Hospital (unrelated to his death) and critical failure to recognize his detained status, resulting in delayed reporting to the coroner as required by law. Clinical lesson: maintain awareness of hyponatraemia's severe neurological consequences and ensure medication review for SIADH risk in patients on antipsychotics.
