Brief Summary:
The purpose of this study is to investigate the relationship among regional transcranial oxygen saturation (rSO2), brain tissue oxygen pressure (PbtO2) and cerebral perfusion pressure (CPP) in patients with severe traumatic brain injury (TBI).

Condition or disease Intervention/treatment
Brain Injuries Device: transcranial oxygen saturation measurement (INVOS Somanetics 5100C)

Detailed Description:
Experience with rsO2 assessed by near infrared spectroscopy (NIRS) in patients with severe TBI is lacking. Reports about the usefulness of rSO2 are contradictory as regards its technical reliability and clinical value. Continuous time-domain analysis comparing rSO2, PbtO2 and CPP has never been carried out and the correlation among these variables remains largely unknown. A significant association between rSO2 and these clinically important variables would suggest that cerebral oximetry provides relevant data signifying that rSO2 might be a useful tool assessing cerebral oxygenation in selected patients with TBI.

Study Type : Observational
Estimated Enrollment : 20 participants
Observational Model: Case-Crossover
Time Perspective: Cross-Sectional
Official Title: Validation of Non- Invasive Regional Transcranial Oxygen Saturation (rSO2) by Comparison With Invasive Brain Tissue Oxygenation (PbtO 2) Measurement in Patients With Severe Traumatic Brain Injury
Study Start Date : July 2008
