RÉSUMÉ
<p><b>OBJECTIVE</b>To evaluate the effects of hyperbaric oxygen (HBO) therapy on patients with postbrain injury neural status.</p><p><b>METHODS</b>Two to 4 courses of HBO therapy and/or medications were used to treat 320 patients who were randomly divided into two groups. Assessment was made with (99m)Tc-ethyl cysteinate dimer ( (99m)Tc-ECD) single photon emission computed tomography (SPECT) before and after treatment.</p><p><b>RESULTS</b>There was a significant difference between the HBO therapy group and the non-HBO therapy group. HBO therapy was superior to medication treatment alone in the recovery of clinical symptoms, control of epilepsy, and resolution of hydrocephalus (P<0.01).</p><p><b>CONCLUSIONS</b>HBO therapy has specific curative effects on patients with postbrain injury neural status, and (99m)Tc-ECD SPECT could play an important role in diagnosing postbrain injury neural status and monitoring the therapeutic effects of HBO.</p>
