Primary ObjectiveTo describe the long-term disorders of consciousness in patients with dysautonomia and hypertonia treated with intrathecal baclofen therapy (IBT).Methods And ProceduresForty-three patients with severe traumatic brain injuries who were previously implanted with an intrathecal baclofen pump were included to be evaluated in the long-term with the Coma Recovery Scale-Revised. The Barthel Index, the Glasgow Outcome Scale, the Ashworth scale, the scores of hypertonic attacks, of sweating episodes and of voluntary motor responses were used to describe functional abilities and residual impairments. A retrospective analysis highlighted patients' characteristics at admission, before surgery and their complications.Main Outcomes And ResultsAfter a mean follow-up of 10 years, nine of 43 (20.9%) patients had died, 13/43 (30.2%) patients were severely disabled or in an unresponsive wakefulness syndrome and 21/43 (48.8%) patients had good recovery of consciousness. The latter patients tended to receive IBT later, suggesting a later development of uncontrolled symptoms of dysautonomia and hypertonia. They needed lower doses of baclofen, suggesting that they had less severe symptoms. Their dysautonomia, limb hypertonia and voluntary motor responses improved significantly compared to patients with poor outcome.ConclusionsRecovery of good long-term consciousness is possible. A low level of consciousness recovery and the early development of severe and persistent symptoms of dysautonomia associated with hypertonia could be linked to poor long-term outcome.
