Noting the last meal in trauma protocol primarily aids in surgical planning. This information is crucial, particularly if the patient requires emergency surgery. If a patient has eaten recently, there is an increased risk of aspiration during anesthesia or surgery, especially if general anesthesia is used. Knowing the timeframe of the last meal allows the surgical team to assess the risk and decide on appropriate management strategies, such as whether to delay surgery if the patient is at high risk for aspiration or to take additional precautions.

In contrast, while the other options also pertain to patient assessment in trauma cases, they do not specifically relate to the last meal. For instance, identifying substance use may involve different histories or toxicology screens, assessing airway trauma usually requires direct evaluation of the airway and signs of obstruction, and imaging decisions depend on clinical findings and mechanisms of injury rather than the patient's last intake of food. Thus, the last meal's timing plays a critical role in the immediate surgical considerations for trauma patients.
