Q: How CT chest can help to establish prognosis in patients subjected to smoke inhalation?
Answer: The standard of care in smoke inhalation patients is to obtain only the chest X-ray (CXR). The presence and frequency of lung parenchymal opacities guide a clinician to the level of prognosis.
Performing CT of the chest is not (yet) a standard of care in patients subjected to smoke inhalation. If obtained, the airway wall thickness to total bronchial diameter (T/D) ratio is a good parameter to establish a prognosis, especially regarding days on the ventilator.
