Cause of death
Anaphylactic reaction to anaesthetic drug (suxamethonium), with underlying coronary atherosclerosis as a contributing condition
AI-generated summary
A 28-year-old woman died during routine dental extraction under general anaesthesia at a regional hospital. Despite competent initial airway management, she developed severe respiratory distress immediately after induction, subsequently progressing to cardiovascular collapse and death. Expert analysis concluded anaphylaxis to suxamethonium was the primary cause, with underlying coronary atherosclerosis contributing. Although the anaesthetist (a foreign-trained doctor) made numerous substandard clinical decisions—including delayed recognition of anaphylaxis, inadequate vasopressor administration, failure to call for senior assistance promptly, and poor fluid management—the coroner found no evidence of criminal negligence. However, critical deficiencies in the overseas recruitment, credentialing, and orientation processes were identified. Recommendations focused on establishing specialist investigation units for medical deaths and ensuring rigorous assessment of overseas-trained practitioners in remote settings.

Coroner's recommendations
- That the Chief Health Officer with the assistance of the State Coroner develop a policy and process for the independent and expert investigation of all deaths that are not reasonably expected to be an outcome of a health care procedure. Such reports should be made available to the coroner and the family as soon as possible.
- That the Medical Board of Queensland consider and determine the allegations made against Dr M. (11 allegations of professional misconduct, of which only one was the subject of this inquest) and investigated by Drs Johnson and Farlow. Its findings should be published in a form that makes them readily accessible to those who might want to be informed of Dr M.'s past performance.
- That Queensland Health and the Queensland Police Service amend their policies and procedures governing the immediate response to deaths in a medical setting to require urgent blood sampling when adverse reaction to anaesthetics or drugs may be involved, specifically to enable testing for mast cell tryptase levels within 4 hours of death.
