Effectiveness evaluation of hyperbaric oxygen in the treatment of neural function impairment casued by the postoperative cerebral edema in patients with meningiomas

Objective: To investigate the effects of hyperbaric oxygen(HBO) on the postoperative cerebral edema in patients with meningiomas. Methods: Fifty-four patients with meningiomas were divided into the observation group and control group(27 cases each group). All patients were treated with the conventional method after operation, and the observation group were additionally treated with HBO. The cerebral edema and neurologic function recovery between two groups were compared. Results: After treatment, the volume of cerebral edema and decreased degree of neurologic impairment score in observation group were obviously more than those in control group(P<0.01). The increased degree of Barthe I index in observation group was significantly higher than that in control group(P<0.01). The difference of the recurrence rate between two group was not statistically significant(P>0.05). Conclusions: The postoperative treatment of meningiomas with HBO can promote the fade away of cerebral edema, and improve the neurologic function.
