Hyperbaric oxygen therapy for acute ischaemic stroke.

Abstract

Background Most cases of stroke are caused by impairment of blood flow to the brain (ischaemia), which results in a reduction in available oxygen and subsequent cell death. It has been postulated that hyperbaric oxygen therapy (HBOT) may reduce the volume of brain that will die by greatly increasing available oxygen, and it may further improve outcomes by reducing brain swelling. Some centres are using HBOT routinely to treat people with stroke. This is an update of a Cochrane Review first published in 2005.Objectives To assess the effectiveness and safety of adjunctive HBOT in the treatment of people with acute ischaemic stroke.Search methods We searched the Cochrane Stroke Group Trials Reg..
