Review of Indications for Endotracheal Intubation in Burn Patients with Suspected Inhalational Injury

Inhalation injury is a major contributor to mortality following burn injury. Despite recognised clinical criteria to guide the intubation of burn patients, concerns remain regarding overutilisation of intubation. Complications can arise as a result of intubation, including ventilator-associated pneumonia (VAP). This study reviews the indications for intubation against the internationally accepted criteria (American Burns Association (ABA) and Denver criteria) for burn patients treated at the Royal Adelaide Hospital (RAH) burns unit between 2017 and 2020. Burn patients who were intubated on arrival to the RAH or in a pre-hospital setting were identified using the BRANZ database. Indications for intubation were compared to the ABA and Denver criteria. A total of 61 patients were identified with a mean total body surface area of 17.8%. A total of 95% of patients met one of the ABA and Denver criteria. The most common ABA and Denver criteria for intubation was deep facial burns or singed facial hair, respectively. Most adult patients with burns admitted to the RAH are intubated per published criteria. Early nasoendoscopy/bronchoscopy may be useful in determining patients who can be safely extubated within 48 h.
