Jugular venous oxygen saturation consistently demonstrates cerebrovascular responsiveness to CO2. The direction and magnitude of changes in cerebral oxyhemoglobin, measured by near-infrared spectroscopy, were similar to those changes in jugular venous oxygen saturation in most of our cases. Interpretation of a negligible change in oxyhemoglobin in one patient, despite an obvious increase in jugular venous oxygen saturation, requires further study comparing near-infrared spectroscopy with standard techniques.

The titration method of mild hypothermia to control intracranial hypertension in severely head-injured patients is clinically feasible. However, the method failed to reduce the incidence of infectious and hematological complications.
