CICM SAQ 2013.1 Q11


You are asked to review a 64-year-old male who has been brought to the Emergency Department having been burned in a house fire. He is drowsy and confused with a persistent cough and unable to give a coherent history. His heart rate is 120 beats/minute, blood pressure is 88/52 mmHg, respiratory rate is 28 breaths/min and oxygen saturation is 94% on high flow oxygen via a reservoir mask.

  • a) List the initial priorities in this patient’s management.
  • b) What features on history and examination would suggest a significant airway injury?
  • c) List the differential diagnoses for his altered mental state.


Answer and interpretation

a) List the initial priorities in this patient’s management.

  • Resuscitation including primary and secondary survey
  • Assessment and management of potential airway burn (including early intubation, not cutting ETT, avoiding nasal tube)
  • Obtain large bore IV access and administration of fluid bolus (20 ml/kg) for probable hypovolaemic shock (mention groins are usually spared in burns and are a good site for clean skin vascath access
  • Look for signs of traumatic injury and assess extent of body surface area and depth of burn
  • Risk of hypothermia
  • Seek collateral history for past medical history, medication history and history of acute events

b) What features on history and examination would suggest a significant airway injury?

  • Burns occurring in a closed space
  • Cough, stridor, hoarseness of voice
  • Burns to face, lips, mouth, pharynx or nasal mucosa
  • Soot in sputum, nose or mouth
  • Hypoxaemia or dyspnea
  • Carboxyhaemoglobin levels >2%
  • Acute confusional state or depressed conscious level

c) List the differential diagnoses for his altered mental state.

  • Traumatic brain injury
  • CO / Cyanide poisoning
  • Alcohol intoxication / drug overdose
  • Other pathology eg CVA, intracranial haemorrhage, seizure-related, hypoglycaemia
