Cause of death

cardiac dysrhythmia/arrest in a 20 year old Down's Syndrome female following abdominal surgery on a background of underlying ventricular septal defect

AI-generated summary

A 20-year-old woman with Down syndrome and Eisenmenger syndrome (cyanotic heart disease with ventricular septal defect) was admitted with abdominal obstruction. After appropriate diagnostic workup, laparotomy was performed for small bowel obstruction caused by a swallowed examination glove. She died postoperatively from cardiac dysrhythmia. Critical lapses included: anaesthesia delivered by registrar without senior consultant present despite extreme anaesthetic risk; failure to provide intensive monitoring (ECG, continuous oximetry) post-operatively despite preoperative oxygen saturation of 48% and known severe cardiac disease; absence of specialist cardiac input despite availability; and placement on general ward rather than ICU. Measures that might have prevented death included low ventilation pressures, inhaled nitric oxide to reduce pulmonary pressures, high-dependency/ICU admission with continuous monitoring, and consultant anaesthetist supervision.

Contributing factors

  • severe cyanotic heart disease with Eisenmenger syndrome and ventricular septal defect
  • extremely low preoperative oxygen saturation (48%)
  • inadequate anaesthetic risk assessment
  • absence of consultant anaesthetist supervision during anaesthesia
  • lack of continuous cardiac monitoring post-operatively
  • lack of continuous oxygen saturation monitoring post-operatively
  • placement on general ward rather than intensive care unit despite critical cardiac condition
  • no ECG monitoring post-operatively
  • absence of specialist cardiac input prior to surgery
  • no use of nitric oxide to reduce pulmonary pressures
  • high ventilation pressures during anaesthesia
  • postoperative fever with elevated temperature (39.6 degrees) not promptly investigated
  • inconsistent oxygen saturation monitoring and recording by nursing staff

Coroner's recommendations

  1. Flinders Medical Centre institute a stipulation that no patient with Eisenmenger's Syndrome be anaesthetised except by a Consultant Anaesthetist.
  2. Flinders Medical Centre investigate the use of nitric oxide as an ancillary anaesthetic agent in the treatment of such patients.
  3. Flinders Medical Centre manage such patients post operatively in the Intensive Care Unit until the Director of ICU certifies that the patient may be moved to the general ward.
  4. Flinders Medical Centre require members of its pathology department to certify in their post mortem reports that they have read all relevant hospital notes relating to deceased patients and they have an appreciation of the deceased's underlying medical conditions.
