Experience with Althesin in the management of persistently raised ICP following severe head injury.

Of 243 patients who underwent intracranial pressure (ICP) monitoring after severe head injury, 42 (17%) were found to have severe persistently raised ICP, in spite of hyperventilation, mannitol, and surgical decompression. Althesin was infused to reduce ICP in these patients. This agent was shown to be effective and safe in reducing ICP, and a significant improvement in cerebral perfusion pressure was demonstrated. In this respect, Althesin may be more effective than barbiturates. However, no improvement in patient outcome was demonstrated in this series.
