Near Infrared Spectrophotometry: Potential Role During Increased Intracranial Pressure
Miller et al1. noted that when the initial intracranial pressure was greater than 40 mm Hg in head injured patients with mass lesions, the eventual neurological outcome was poor. They further noted that in patients without mass lesions presenting initially with a normal intracranial pressure, a subsequent rise greater than 20 mm Hg was associated with increased morbidity. These observations illustrate that, at the present time, the widespread practice of monitoring intracranial pressure serves two functions, that of providing a prognostic index for future outcome, and a means of continuously monitoring the progress of a hospitalized patient, allowing rapid intervention at times of increasing intracranial pressure.
