global hypoxic cerebral injury following medical intervention for high velocity missile injury to the head

AI-generated summary

Daniel Cowan, aged 15, sustained a penetrating head injury from a homemade air gun while with friends. Despite appropriate emergency response and comprehensive multidisciplinary medical management at Royal Children's Hospital including neurosurgery, the injury was devastating. He initially survived with Glasgow Coma Scale 9, underwent intubation, surgery, and decompressive craniectomy. However, he developed staphylococcal meningitis, severe cerebral oedema with intracranial pressure exceeding 90mmHg despite aggressive intervention, and ultimately global hypoxic cerebral injury leading to death. The coroner found medical management was reasonable and appropriate. The death resulted from the severity of the primary ballistic injury rather than medical errors. Prevention centred on firearm safety education, proper storage, and regulatory compliance rather than clinical management improvements.
