Head injury (epidural haematoma with cerebral coning following craniotomy)

AI-generated summary

Dwayne Michael Jones, aged 9, had Trisomy 10, a rare congenital chromosomal disorder causing severe developmental delay and neurological abnormalities. On 11 April 2000, he fell from a computer desk and struck his head. His GP, Dr A., diagnosed concussion and sent him home. When Dwayne vomited—abnormal for him—his mother took him to Kalgoorlie Regional Hospital, where resident intern Dr P. also diagnosed concussion. The following morning, Dr W. arranged a CT scan, but it could not be completed without sedation. Dr A. delayed the scan until 13 April, stating Dwayne appeared stable. When the CT scan was finally performed, it revealed a massive epidural haematoma. Emergency surgery was attempted but Dwayne died from cerebral coning. The coroner found the critical failure was delayed CT imaging. Early neurological imaging on 11 April would likely have changed the outcome. The case highlights the challenge of assessing deeply disabled children and the importance of using diagnostic imaging when clinical assessment is difficult, particularly in regional settings with limited specialist support.

Contributing factors

  • Delayed CT imaging—CT scan not performed until 13 April 2000, two days after injury
  • Failure to recognise the significance of vomiting and neurological signs in a child with profound baseline neurological disability
  • Lack of established neurological baseline for the patient
  • Unavailability of anaesthetic services on afternoon of 12 April 2000
  • Diagnostic uncertainty in assessing a child with severe congenital abnormalities
  • Dr A.'s reliance on clinical judgment without neurological imaging in a complex case
  • Limited serial neurological observations due to difficulty assessing the patient
  • Lack of supervision and support for junior resident intern (Dr P.) in regional hospital

Coroner's recommendations

  1. GPs who are consistent carers for profoundly neurologically disabled children should establish serial (annual) neurological baselines for their patients to enable assessment in cases of future trauma
  2. GPs, especially those in regional areas, should consider CT scans as primary diagnostic tools for head injury where there is any difficulty establishing a satisfactory management plan
  3. Where there is a delay in providing a CT scan, the doctor ordering the scan or the ongoing carer must personally reassess the patient to determine any deterioration or improvement and formulate appropriate management accordingly
  4. Recognition of the need for lowered threshold for diagnostic imaging (CT scans) when clinical assessment is difficult, particularly in cases of profound disability
  5. Continued support and improvement of specialist resources in regional centres, including part-time specialist coverage and supervision of junior medical staff
