The aim of this study was to assess, in two experiments, the safety and efficacy of the PFC emulsion Oxycyte as an oxygen therapeutic for TBI to test the hypothesis that early administration of this oxygen-carrying fluid post-TBI would improve brain tissue oxygenation (Pbt O2 ). ⋯ Although Oxycyte did not cause cerebral vasoconstriction, its use at the dose tested while breathing 100% O2 did not improve Pbt O2 following TBI. However, Oxycyte treatment while breathing a lower enriched oxygen concentration may improve Pbt O2 after TBI.
