AbstractJugular bulb oximetry provides the first bedside available information on cerebral oxygen utilization. An extensive analysis was made of all initial jugular bulb oximetry data obtained in 150 patients within the first 12 h after severe traumatic brain injury. These data revealed initial abnormal jugular bulb saturation values in 57 patients (= 38% of study population), with a predominance of jugular bulb desaturation (observed in 45 patients). This confirms earlier reports that revealed a high incidence of disturbed and inadequate cerebral perfusion in the first hours after brain injury. Jugular bulb desaturation was especially related to systemic causes (such as a lowered cerebral perfusion pressure observed in 29 patients, and a lowered arterial carbon dioxide tension in 24 patients). These findings could have important implications for the emergency management of severely head-injured patients, as outcome might possibly be improved by better attention to all systemic factors that might reduce cerebral perfusion in the early hours after traumatic insult.
