Abstract
Oxygen
is frequently administered to patients with suspected stroke. However,
the role of oxygen therapy in ischemic stroke remains controversial in
light of the failure of three clinical trials of hyperbaric oxygen
therapy to show efficacy, and the fear of exacerbating oxygen free
radical injury. The previous trials had several shortcomings, perhaps
because they were designed on basis of anecdotal case reports and little
preclinical data. Most animal studies concerning oxygen therapy in
stroke have been conducted over the last 6 years. Emerging data suggests
that hyperbaric and even normobaric oxygen therapy can be effective if
used appropriately, and raises the tantalizing possibility that
hyperoxia can be used to extend the narrow therapeutic time window for
stroke thrombolysis. This article reviews the history, rationale,
mechanisms of action and adverse effects of hyperoxia, the key results
of previous hyperoxia studies, and the potential role of oxygen therapy
in contemporary stroke treatment.
