Cardiac Surgery
Cerebral oximetry can improve the quality and
decrease the cost of coronary artery bypass surgery.
Randomized interventional study evaluating
the effect of maintaining adequate cerebral oxygenation on complications,
length of stay and outcome. Control patients are blinded to the
monitor and intervention patients are managed based on cerebral
oximetry values.
Use of cerebral oximetry to manage cardiac
surgery patients post-operatively.
Pilot evaluation of usefulness of cerebral
oximetry in the ICU after cardiac surgery.
Cerebral oximetry and transcranial Doppler
identification of periods of high embolic delivery during cardiac
surgery.
Cerebral oximetry and the effects of
slow rewarming on neuropsychological outcomes after cardiac surgery.
Partially supported by the National Heart Foundation
of Australia.
Comparison of outcomes following randomization
to on- or off-pump cardiac surgery.

Pediatric Cardiac
Surgery
The effects of hematocrit management
using cerebral oximetry on long term developmental outcomes.
Study involves managing patient's hematocrit
to different levels during pediatric cardiac surgery and evaluating
long term neurological and developmental outcomes.
The use of cerebral oximetry to manage
regional antegrade low flow perfusion in patients during the Norwood
procedure.
top
Neurosurgical ICU
Transcranial oxygen saturation monitoring
in severe traumatic brain injury multicenter trial.
Examining correlation between cerebral oximeter
and routine monitors such as intracranial pressure in head injury,
two centers recruited.
Methods of predicting delayed cerebral
ischemia in subarachnoid hemorrhage.
NIH grant study.
An evaluation of cerebral oximetry to
detect intracranial vasospasm.
Can cerebral oximetry provide information
on increased intracranial pressure after traumatic brain injury?
top
Tissue Oximetry
NIRS guided resuscitation of hemorrhagic
shock.
Definition of transfusion triggers by
the measurement of tissue oxygenation.
Measurement of spinal cord oxygenation
during sequential intercostals and lumbar artery clamping in the
porcine model.
top
Sleep Studies
Cerebral oxygenation during chronic obstructive
pulmonary disease, two centers.
top
Emergency/Trauma/First
Response
Evaluation of cerebral oximetry as a
monitor for first response personnel, four centers.
Is cerebral oximetry useful during medivac
air transport of emergency patients?
top
General Surgery
Use of cerebral oximetry during total
knee arthroplasty with and without complete tourniquet occlusion.
Can cerebral oximetry improve the quality
and decrease the cost of major general surgery in the elderly?
Randomized interventional study evaluating
the effect of maintaining adequate cerebral oxygenation on cognitive
decline, complications, length of stay and outcome. Control patients
are blinded to the monitor and intervention patients are managed
based on cerebral oximetry values. Four centers enrolled.

Other
Can cerebral oximetry measure spinal cord oxygenation?
A cadaveric study.
The measurement of changes in autoregulation
in patients with Alzheimer's disease.
Changes in cerebral oxygenation in sickle
cell patients during crisis and after transfusion, two centers.
Can cerebral oximetry provide qualitative estimates
of changes in cerebral blood flow?
NIH grant study.
Cerebral oximetry responses during exercise
in congestive heart failure patients.
Can cerebral oximetry identify vasovagal syncope?
