Brief Summary:
Brain damage as a result of decreased oxygen to the brain is found in 80% of patients that die with severe head injuries. Laboratory studies in animals and clinical trials have shown that increasing oxygen in the brain results in better brain oxygen consumption, less cell death, and better functional outcome. This study will test the hypothesis that Oxycyte is an effective way to increase brain oxygen levels in severe head injury.

Condition or disease Intervention/treatment Phase
Traumatic Brain Injury Drug: perfluorocarbon emulsion (Oxycyte) infusion Phase 2

Detailed Description:

Decreased brain oxygen in severe brain injuries appears to be implicated in poor functional outcome and death. Animal and clinical studies have shown that increasing brain oxygen in such patients improves functional outcome, and Oxycyte has been shown to be an effective means of delivering oxygen to tissues, including the brain. This study is an eight patient proof of concept study to test the effects of oxygen delivery with Oxycyte in patients with a severe traumatic head injury with a Glasgow Coma Scale (GCS) score of 3 to 9.

Subjects diagnosed with a severe head injury (GCS 3-9) who receive a brain oxygen monitor and microdialysis catheter, will undergo baseline monitoring for 4 hours. In the first 4 subjects the Fi02 on the ventilator will be increased to 50% for a 4 hour stabilization period and this will be followed by a single intravenous infusion of 3ml/kg of Oxycyte. The Fi02 will remain at 50% for 24 hours.

In the second 4 subjects the Fi02 on the ventilator will be increased to 100% for a 4 hour stabilization period and this will be followed by a single intravenous infusion of 3ml/kg of Oxycyte. The Fi02 will remain at 100% for 24 hours.

Subjects will be enrolled, treated, and then monitored by LICOX 02 monitor before and after infusion of PFC, and then for at least 48 hours following the discontinuation of Oxycyte.
