What should be continuously monitored in a patient with head injury?

In the context of a patient with a head injury, continuously monitoring the level of consciousness is crucial because it provides vital information about the patient's neurological status. Changes in consciousness can indicate evolving conditions such as increased intracranial pressure, potential brain herniation, or worsening neurological function. The Glascow Coma Scale is often employed to assess a patient's level of consciousness, allowing healthcare providers to track any changes over time that may necessitate urgent interventions.

While monitoring vital signs such as pulse rate, blood pressure, and respiratory rate is important, they do not offer the same direct insight into the brain's condition as level of consciousness. For instance, a patient may maintain stable vital signs despite significant neurological deterioration. Therefore, closely observing the level of consciousness allows for timely responses to potentially life-threatening changes in a head-injured patient’s condition.
