What is the next step after confirming endotracheal intubation in the trauma protocol?

• A. Begin mechanical ventilation or continue assisted ventilation
• B. Pause for blood tests
• C. Administer diuretics
• D. Place patient in a left lateral decubitus position

Answer: (A)

After confirming endotracheal intubation, the priority is to ensure ventilation. Secure the airway and immediately connect to a ventilator or bag-valve device to deliver breaths with adequate oxygenation and ventilation. Starting or continuing assisted ventilation (often with high FiO2 initially) directly supports gas exchange in a patient who may be unable to breathe effectively on their own due to injury or consciousness level. The other actions don’t address this immediate need for oxygen delivery and CO2 removal: blood tests can wait until the airway/ventilation are stabilized; diuretics aren’t used to manage an acute airway situation; and moving the patient to a left lateral decubitus position doesn’t improve ventilation after intubation.
