At UCI Beckman laser Institute researchers want to use cerebral non-invasive oximetry instrument call Diffuse Optical Spectroscopy Imaging (DOSI)to assess cerebrovascular reactivity in human brain and has great temporal resolution, with details information about the brain oxygenation saturation and hemoglobin concentration.

Condition Intervention
Hypoxia-Ischemia, Brain
Device: Cerebral Oximetry Diffuse optical spectroscopy imaging

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: Assessing Cerebrovascular Reactivity Based on Cerebral Oximetry

Further study details as provided by University of California, Irvine:

Primary Outcome Measures:
  • Optical Imaging assess of Brain blood flow during surgical procedure [ Time Frame: 6 hours ] [ Designated as safety issue: No ]
    The brain will be monitored use DOSI during surgery

Enrollment: 78
Study Start Date: December 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Cerebral Oximetry Diffuse optical spectroscopy imaging
    cerebral non-invasive oximetry instrument, assess cerebrovascular reactivity in surgical patients
    Other Name: DOSI, developed at UCI,Beckman Laser Institute,
Detailed Description:

This study does not involve medical intervention. DOSI is noninvasive and only involves data collection after the placement of a probe on the subject's forehead during surgery.

Subject who scheduled for elective surgery under general anesthesia at UCIMC will be recruited.
