Cause of death

Hypoxic ischaemic brain injury complicating a cardiac arrest during anaesthetic induction for an elective inguinal hernia repair

AI-generated summary

A 46-year-old male underwent elective inguinal hernia repair at a private hospital. During anaesthetic induction, he experienced cardiac arrest. The endotracheal tube (ETT) was visualized passing through the vocal cords, but likely became dislodged, kinked, or obstructed. Early clinical signs were misattributed to anaphylaxis or bronchospasm rather than ETT malposition. The ETT position was not visually rechecked until late in the resuscitation, at which point it was found in the oesophagus. By then, severe hypoxic brain injury had occurred, leading to brain death. Key lessons: maintain high suspicion for airway malposition despite initial visualization; rely on capnography waveform as the most reliable confirmation; avoid anchoring bias on initial diagnostic impressions; visually recheck ETT position early in unexplained deterioration; ensure capnography is immediately available and its absence or abnormality triggers systematic verification.

Contributing factors

  • Endotracheal tube dislodgement, kinking, or early obstruction
  • Failure to visually recheck ETT position until late in resuscitation
  • Anchoring bias on diagnosis of anaphylaxis/bronchospasm
  • Absence of normal ETCO2 trace not acted upon
  • Reliance on auscultation and initial visualization rather than continuous capnography confirmation
  • Lack of effective pre-oxygenation prior to induction
  • High airway pressures misinterpreted as anaphylaxis rather than malposition
  • Delayed involvement of fourth anaesthetist who identified malposition

Coroner's recommendations

  1. The Australian and New Zealand College of Anaesthetists should establish guidelines emphasising the use of End Tidal Carbon Dioxide in Endotracheal Tube placement confirmation
