PLAINSBORO, N.J., April 25, 2006 (PRIMEZONE) -- Integra LifeSciences Holdings Corporation (Nasdaq:IART) today announced that the Department of Neurosurgery and Surgery, University of Pennsylvania will present the results of seven clinical studies on the application of the LICOX® Brain Tissue Oxygen Monitoring System to the management of brain injured patients, including those with severe traumatic brain injury or subarachnoid hemorrhage at the 2006 American Association of Neurological Surgeons (AANS) Annual Meeting in San Francisco, CA, this week.

The key findings of these studies include the following:

• 
  
  
  
  Conventional strategies of ICP and CPP management may result in significant reductions in cerebral oxygenation despite what would otherwise be considered adequate intracranial pressure and cerebral perfusion.





• Occult cerebral hypoxia occurs in TBI patients who receive neurocritical care despite traditional practices to maintain CPP. Medical interventions other than those to treat ICP and CPP can improve BtO2. These interventions increase the number of possible therapies for severe TBI in the intensive care unit.





• Occult cerebral hypoxia occurs in SAH patients who receive conventional neurocritical care. Interventions to augment CPP and FiO2 can help to maintain cerebral oxygenation in poor grade SAH patients.





• SAH patients require a higher CPP than TBI patients to maintain cerebral oxygenation. Guidelines developed for TBI may not be applicable for SAH.





• CPP values do not always ensure adequate cerebral oxygenation after SAH.





• Poor outcome in older patients after SAH may be associated with a greater daily duration of brain hypoxia. In addition, older patients appear to respond less to pressor treatments to augment BtO2 than young patients.





• Fluid therapy to increase CVP does not ensure cerebral oxygenation in all patients during the first 25 hours after SAH..

"Since we started using the LICOX® Brain Tissue Oxygen Monitoring System in 2002 we have found it to be a useful addition to existing neuromonitoring methods. In addition to our experience in TBI, we now have added considerable experience in SAH patients, where LICOX® seems to be a useful tool too," said Peter D. LeRoux M.D., FACS, Associate Professor and Vice Chairman, Department of Neurosurgery, University of Pennsylvania.
