RESUMO
<p><b>OBJECTIVE</b>To study the curative effect of wilsonii injecta on severe head injury (SHI).</p><p><b>METHODS</b>A total of 120 patients with SHI were divided randomly into 2 groups, the patients treated with conventional methods as Group A (n=60) and the patients treated with wilsonii injecta as Group B (n=60). The changes of neural function indexes were evaluated with Glasgow Coma Scale (GCS) before treatment and with Glasgow Outcome Scale (GOS) after treatment, simultaneously, the parameters of hemorrheological indexes (HI), brain electrical activity map (BEAM) and transcranial Doppler sonography (TCD) were observed before and after treatment.</p><p><b>RESULTS</b>In Group B, the clinical GCS, the HI, the BEAM and the prognosis GOS were improved much more than those in Group A. And the TCD parameters in Group B decreased, which had significant difference compared with that in Group A (P<0.01).</p><p><b>CONCLUSIONS</b>Wilsonii injecta can rapidly improve the injured p ersons' conscious states, the abnormal BEAM and the surviving quality. It suggests that the improvement of the HI is related to the relief of the vasospasm of the arterial blood vessels in the brain, which may be one of the important mechanisms of wilsonii injecta in improving the prognosis.</p>
