Advances In The Treatment Of Neuropathic Pain With Hyperbaric Oxygen

Neuropathic pain (NPP) refers to the pain caused by primary or secondary injury or dysfunction of the peripheral or central nervous system, and usually requires multidisciplinary treatment. However, most pharmacological and non-pharmacological interventions can only temporarily and/or moderately improve pain-related symptoms, and they often produce unbearable adverse reactions or cause drug resistance. Hyperbaric oxygen (HBO2) therapy has been widely used in the clinical treatment of some diseases due to its advantages of safety, few side effects, no resistance, and non-invasiveness. In recent years, increasing numbers of basic and clinical studies have been conducted to investigate the efficacy and mechanism of HBO2 in the treatment of NPP, and great progress has been made in this field. In this paper, we briefly introduce the pathogenesis of NPP and therapeutic effects of HBO2 and summarize the mechanisms underlying the effects of HBO2 in treating NPP, which may provide reference for the clinical treatment of pain with HBO2.
