Following serious injury resulting in airway blockage, the standard of care is to intubate, which involves inserting a flexible tube into the trachea to maintain airflow, followed by immediate surgical intervention (41% of injuries). Mechanical ventilation (65% of injuries), blood transfusion (28% of injuries) and tracheostomy (22% of injuries) are also common following trauma. Head injuries often coincide with craniofacial trauma, extradural hematoma (bleeding in between the skull and the dura mater), and subdural hematomas (bleeding between the dura mater and the brain).
