Cause of death

Airway obstruction due to sublingual and submandibular cellulitis (Ludwig's angina) following right lower molar tooth extraction

AI-generated summary

A 27-year-old man died from airway obstruction due to Ludwig's angina (bilateral sublingual and submandibular cellulitis) following a tooth extraction. Critical failures included: delayed treatment with inadequate timely transfer to definitive surgical care; absence of medical records accompanying the patient during private vehicle transfer; lack of diagnosis recognition at the surgical hospital; no pre-operative discussion between anaesthetist and surgeon about the serious diagnosis; and premature extubation post-operatively. The anaesthetist stated he would have sought senior input and likely maintained intubation had he known the diagnosis. The coroner found the patient suffered from bilateral Ludwig's angina confirmed at autopsy, not merely a unilateral submandibular abscess. Key preventable errors included communication failures and failure to appreciate the severity and implications of this life-threatening condition.

Contributing factors

  • Delayed transfer from Queen Elizabeth Hospital to Royal Adelaide Hospital
  • Transfer by private vehicle instead of ambulance resulting in no medical records accompanying the patient
  • Failure to clearly communicate diagnosis of Ludwig's angina to the Royal Adelaide Hospital surgical and anaesthetic teams
  • No pre-operative consultation between anaesthetist and surgeon
  • Lack of awareness by anaesthetist of serious diagnosis at time of decision to extubate
  • Premature extubation post-operatively in a patient with bilateral Ludwig's angina
  • No discussion with surgeon about nature and severity of the condition before surgery
  • Inadequate post-operative monitoring and failure to escalate when respiratory distress noted
  • Delayed seeking of definitive dental treatment by patient over several months

Coroner's recommendations

  1. Queen Elizabeth Hospital should review processes and guidelines to ensure that in all cases of transfer, whether by ambulance or private vehicle, appropriate medical notes accompany the patient to the receiving hospital
  2. Minister for Health should remind the public of the importance of seeking timely treatment for signs of dental infection, as delayed treatment can allow infective processes to progress to life-threatening conditions such as Ludwig's angina
