Cause of death
retroperitoneal haemorrhage due to anticoagulation following right cerebrovascular infarct following intra-arterial cannulation of the right carotid artery
AI-generated summary
A 66-year-old woman died from retroperitoneal haemorrhage following anticoagulation for stroke caused by intra-arterial central venous catheter placement. The catheter was mistakenly inserted into the right carotid artery instead of the jugular vein. Critical failures included: non-recognition of arterial blood on blood gas analysis (5.02am, 17 June), radiologist's failure to identify malposition on chest X-ray, eight-day delay before catheter removal, and delayed recognition of haemorrhagic shock. When haemoglobin dropped from 138 to 71 g/L, staff dismissed this as 'dilutional' despite anticoagulation therapy, failing to consider retroperitoneal haemorrhage. The MET team lacked appropriate consultant input and delayed diagnosis. A four-hour gap occurred between diagnosis of haemorrhagic shock and ICU review. The coroner found the death almost certainly preventable, highlighting serious deficiencies in MET team consultation and supervision.

- failure to recognise haemorrhagic shock
- misinterpretation of haemoglobin drop as dilutional rather than bleeding
- inadequate MET team consultation and expertise
- four-hour delay between diagnosis of haemorrhagic shock and ICU review
- anticoagulation therapy contributing to retroperitoneal bleeding
Coroner's recommendations
- Royal Hobart Hospital should initiate a review of the MET team with focus upon consultancy input and supervision
