Persistent vegetative state (PVS) in patients with hyperbaric oxygen therapy and SPECT observed (40 cases)

r check s Dun ship no significant improvement in regional cerebral ischemia . 3 Discussion of hyperbaric oxygen therapy on PVS patients is a safe and effective rehabilitation measures , has important clinical significance. HBO can improve the cerebral microcirculation . Increase in cerebral blood oxygen content , increased oxygen tension, reduce blood cell adhesion to endothelial cells , blood cells themselves to improve the rheological , reduce aggregation, eliminate and reduce thrombosis, promote cerebral ischemia , hypoxia improved function in energy metabolism Recovery , ATP generation increased. At the same time suck pure oxygen under high pressure ,[link widoczny dla zalogowanych], can make the vertebral artery blood flow increased significantly help to improve brain stem oxygen partial pressure , improve the status of ischemia and hypoxia and the brain stem ascending reticular activating system activation . Conducive to the recovery of brainstem function , accelerate the awakening. The patients confirmed by clinical analysis and checking ,[link widoczny dla zalogowanych], PVS patients in the conventional treatment based on treatment with HBO can significantly improve the prognosis ,[link widoczny dla zalogowanych], HBO treatment is started earlier ,[link widoczny dla zalogowanych], PVS shorter duration , the better the effect . HBO treatment improved the patient's level of consciousness and neurological function is to present one of the effective treatment of PVS . 40 cases of PVS patients admitted to hospital routine SPECT scan showed reduced rCBF in varying degrees to reveal the condition of PVS patients is closely related with the cerebral blood flow abnormalities . Hyperbaric oxygen treatment group after two courses of routine clinical symptoms SPECF review found that significant improvement in recovery and 20 cases of PVS patients whose rcBF also showed significant improvement , but no significant improvement in clinical symptoms of PVS patients and no improvement in their rcBF no obvious Improvement; reveal the changes in rCBF and improvement of clinical symptoms is closely related to rhyme , SPECT results and clinical match ,[link widoczny dla zalogowanych], SPECr objective assessment of cerebral perfusion imaging is an important therapeutic tool for HBO .
