Hyperbaric oxygen (HBO) therapy is the medical use of oxygen at a level higher than atmospheric pressure for treating hypoxic disease (Hu et al., 2016). Secondary injuries, such as edema, neuronal necrosis, blood and spinal cord barrier disorders, have been shown to be strongly associated with a large number of inflammatory factors. HBO can effectively inhibit the generation of inflammatory factors, and promote repair and regeneration of neurons. Moreover, HBO can relieve hypoxia, protect the surrounding tissue, reduce the mitochondrial dysfunction in injury area, reduce bleeding area and reduce edema. HBO has been used to treat TSCI for a long time. Holbach et al. first found that HBO therapy improved postoperative dysfunction in TSCI patients. In recent years, a number of clinical studies have focused on HBO therapy for TSCI, and the patients recovered well. Atmospheric pressure is very low in the plateau, and oxygen content in plateau environment is less than that in plain area. Secondary apoptosis induced by ischemia and hypoxia after SCI is the main cause of spinal cord dysfunction. HBO therapy can increase the dissolved oxygen, which is helpful for the recovery of incomplete spinal nerve function. Therefore, HBO therapy has higher therapeutic value in plateau than in plain.
