When treating a patient with a suspected closed head injury, what should be monitored closely?

When treating a patient with a suspected closed head injury, it is critical to monitor the level of consciousness and signs of increasing intracranial pressure. A closed head injury can lead to swelling or bleeding within the skull, which can increase pressure around the brain. This elevated intracranial pressure can compromise brain function and awareness.

Monitoring the level of consciousness allows the EMT to assess the patient's neurological status, as any changes can indicate worsening of the condition. For instance, decreased responsiveness or altered mental status could signal increasing intracranial pressure or other complications requiring immediate intervention.

Signs of increasing intracranial pressure may include pupil changes, abnormal motor responses, headache, nausea, vomiting, or altered vital signs. These indicators provide essential information about the patient's evolving condition and help guide further treatment decisions.

In contrast, while body temperature, skin color, heart rate, blood pressure, respiratory rate, and depth are all important vital signs to monitor, they do not directly assess the specific risks associated with a closed head injury as effectively as level of consciousness and signs of increased intracranial pressure. These aspects are vital in the early recognition and management of life-threatening complications in head trauma patients.
