They were divided into two groups according to the random number table method. Sixty-one cases of the control group were treated with electrical stimulation of the right median nerve，and the observation group sixty-one patients were treated with right median nerve electrical stimulation combined with hyperbaric oxygen therapy. After 6 courses of treatment，the therapeutic effects of the two groups were compared. Results The observation group’s rCBV（3.56±0.67）mL/100 g，rCBF（43.57±5.22）mL/100 g，Vm（55.42±5.42）cm/s，Vp（68.42±4.51）m/s and 6 courses after treatment in the observation group brainstem blood perfusion（8.88±1.44）mL/（min·100 g），thalamic blood perfusion（12.56±1.82）mL/（min·100 g），cortical area blood perfusion（13.58±2.37）mL/（min·100 g）im⁃ proved better than In the control group（P<0.05），the disease improvement rates of 1 course，3 courses，and 6 courses after treatment were 50.82%，73.77%，and 95.08%，which were higher than those of the control group（P<0.05）. At the same time，the GCS scores and MMSE scores of the observation group were higher than those of the control group for 3 courses and 6 courses after treatment（P<0.05）. Conclusion Applying right median nerve electrical stimulation combined with hyperbaric oxygen therapy to patients with craniocerebral trauma can increase cerebral blood flow and improve cognitive function. 【Key words】 Craniocerebral trauma；Median nerve electrical stimulation；Hyperbaric oxygen；Awakening；Cognitive function；Cerebral blood flow
