soft tissue injuries and fractures
of the bones of the face and neck are common and vary in severity
in face and neck injuries, your priorities are to:
prevent further injury to the cervical spine; manage the airway and ventilation of the patient, and control bleeding
may be caused by heavy bleeding into the airway, swelling in and around the structures of the airway located in the face and neck, and injuries tot he central nervous system that interfere with normal respiration
airway compromise
use direct pressure with a dry, sterile dressing.
to control heavy bleeding from soft-tissue injuries to the face
use a moist, sterile dressing–
if brain tissue is exposed
maintain a high index of suspicion for patients with unequal pupils, this may indicate
an injury to the brain
air embolism
