RESUMO
<p><b>OBJECTIVE</b>To evaluate current diagnosis and therapeutic effect and outcome of diffuse axonal injury (DAI) in 169 patients.</p><p><b>METHODS</b>The data of 169 DAI patients treated in the Second, Sixth, Eighth and Ninth Hospitals of Shenzhen and Shekou Hospital from January 2001 to January 2005 were collected. The imaging features, classification, GCS (Glasgow coma scale), treatment and outcome of the 169 patients were retrospectively analyzed.</p><p><b>RESULTS</b>The simpler the imaging features, the closer the focus of DAI to the periphery of hemisphere and the higher the GCS score, the better the prognoses of DAI patients will be.</p><p><b>CONCLUSIONS</b>The prognoses of DAI patients are closely related to the imaging features and classification, GCS and clinical treatment.</p>
RESUMO
<p><b>OBJECTIVE</b>To sum up the experience in treating very severe traumatic brain injuries.</p><p><b>METHODS</b>Retrospective analysis of 68 patients with very severe traumatic brain injuries treated in our hospital from 1997 to 2002 was done.</p><p><b>RESULTS</b>Forty-one (60%) patients died. In the 50 patients treated surgically 27 (40%) survived, 8 recovered well, 9 had moderate disability and 10 had severe deficits. The 18 patients treated non-operatively all died.</p><p><b>CONCLUSIONS</b>Much attention should be given to the observation of the changes of severe brain injuries with cranial base injury. Timely operative decompression, basic life support, keeping effective brain blood perfusion and effective oxygen supply, improving cerebral microcirculation and preventing or controlling complications are the main methods to raise the successful rate of treating very severe brain injuries and the life quality of the patients.</p>
