A 36-year-old male involved in a motorcycle collision arrives at the trauma bay with a Glasgow Coma Scale score of 8. To prevent secondary brain injury, which intervention is most appropriate?
Elevating the head of the bed to 30 degrees
Administering aggressive fluid resuscitation
Inserting an intracranial pressure monitor
Maintaining adequate oxygenation with SpO2 greater than 94%
Maintaining adequate oxygenation is crucial in the prevention of secondary brain injury. Hypoxia can exacerbate brain injury by increasing ischemia and causing further neuronal damage. Ensuring an oxygen saturation (SpO2) greater than 94% helps to ensure that the brain is receiving sufficient oxygen supply, thus mitigating the risk of secondary injury. Other options, such as aggressive fluid resuscitation or inserting an intracranial pressure monitor, while important, are not the immediate priority for preventing secondary brain injury in the pre-hospital or initial emergency setting. Elevating the head of the bed can help reduce intracranial pressure but is secondary to ensuring oxygenation.
