XXV. Head Trauma  (Don Marion  Rusner Origin and
     Evaluation of Plateau Wavews  J. Neurosurg 60: 312-
     324  1984)

       A. Don't treat hypertension without thinking about
          ICP.  The brain may need that pressure for
          perfusion in the face of an elevated ICP.

       B. Goals in the management of head injured
          patients

            1. Identification and treatment of
               concommitant injuries.

                 a. Head injured patients may have trauma
                    to other areas of the body that can
                    impact on ICP. These include tension
                    pneumothorax and pericardial
                    tamponade. If the combination of high
                    airway pressures and brain swelling
                    exists, think of pneumothorax and
                    mainstem intubation. In one case of a
                    head injured patient with unknown
                    tension pneumo, airway pressure rose
                    to 50-60 and CVP to 18-20. Blood was
                    present in the ET tube. 

                 b. ET tubes placed in the field by
                    paramedics or by ER personnel may not
                    be in the correct location. Verify
                    correct positioning by auscultation
                    and/or direct larngoscopy upon patient
                    arrival. If a rush roller patient
                    appears blue upon arrival in the OR,
                    think esophageal instubation. 

                 c. Cervical Spine fractures, basilar
                    skull fractures, avoid N2O

                 d. Prevention of Secondary brain injury
                    by maintaining cerebral oxygenation
                    and perfusion.

                 e. Patient's with a Glascow coma scale of
                    less than 7 may be routinely
                    intubated. If you intubate with sux,
                    you must follow with vec to prevent
                    bucking.

                 f. Treatment of ICP

       C. If you pick up an intubated patient at the ICU
          for transport to the OR, deepen the paralysis
          and give judicious amounts of fentanyl.
