Head Injury Guidelines and Assessment: Glasgow Coma Scale
The Glasgow Coma Scale was developed to provide a simple way for health care practitioners of different skill levels and training to quickly assess a patient's mental status and depth of coma based upon observations of eye opening, speech, and movement. Patients in the deepest level of coma:
Those in lighter comas may offer some response, to the point they may even seem awake, yet meet the criteria of coma because they do not respond to their environment.
Glasgow Coma Scale
A person who is awake has a Glasgow Coma Scale of 15, while a person who is dead would have a score of 3. The abnormal motor responses of flexion and extension describe arm and leg movement when a painful stimulus is applied.
Trauma patients are often "touched" by many health care practitioners; from first responders, EMTs, emergency physicians, surgeons and neurosurgeons. Not only is it important to assess the depth of coma but also to know if the patient is improving or deteriorating. The Glasgow Coma Scale allows that analysis to occur.
The scale is used as part of the initial evaluation of a patient, but does not assist in making the diagnosis as to the cause of coma. Since it "scores" the level of coma, the GCS can be used as a standard method for any health care practitioner to assess change in patient status.
