BackgroundThe aim of this systematic review was to assess the benefits and harms of supplemental oxygen (HBOT/NBOT) for treating and preventing migraine and cluster headaches.Material And MethodsAll randomized trials comparing the effect of supplemental oxygen on migraine or cluster headache with those that exclude supplemental oxygen were included in this review. The systematic search included all relevant sources according to the paradigms of the Cochrane Collaboration. Data were analyzed with RevMan 4.2.ResultsNine trials involving 201 participants satisfied the inclusion criteria. HBOT was effective in relieving an acute migraine and seemed to be sufficient in the treatment of an acute cluster attack. NBOT was effective in terminating acute cluster headache compared to sham treatment, but not in comparison to sublingual ergotamine. There was no evidence for any prophylactic effects. Serious adverse effects were not noted in the trials investigated.ConclusionsThere is some evidence that HBOT is effective for termination of acute migraine. NBOT was similarly effective in cluster headache, however with sparse data. Because of costs and poor availability HBOT cannot be regarded as a routine therapy. Further indications in the case of treatment failure using standard therapy need to be defined based on data of future clinical trials.
