Abstract
Objectives.To evaluate the changes of vegetative parameters and behavioural assessment in comatous patients after severe brain injury during the Multimodal-Early-Onset-Stimulation (MEOS) in early rehabilitation.
Material and Methods.We studied 16 predominantly male (3: 1) patients, age mean 43.6 (16–77) years. Mean coma duration was 22.2 (8–41) days, therapy duration (MEOS) 9.8 (1–30) days. The initial GCS was 6.6 (3–9), KRS 5.3 (0–15). Including criteria for therapy: Severe head trauma, coma for at least 48 hours (GCS < 8), vegetative stability, normal intracranial pressure, abandon of mechanical ventilation, sedation and severe infections. MEOS was finished in achieving GCS > 9, follow-up investigations were made after 2 years.
Results.We identified significant changes in two vegetative parameters (heart/respiratory frequencies), even in deep coma (GCS 3–4). Most significant changes were caused by tactile and acoustic stimulation. Standardized behavioural assessment turned out to be particularly advisable in cases of medium coma (GCS 5–7). Stimulation of tactile and acoustic senses resulted mainly in mimical, head and eye movements. Follow-up was possible in 14 patients: One remained in a vegetative state (GOS 2), two exhibited severe neurologic/neuropsychologic deficits, depending on care (GOS 3), six substained major functional deficits (GOS 4), at though they were able to perform the tasks of daily life on their own, three patients reached GOS 5. Two returned to their former jobs.
Discussion and Conclusion.The present results indicate that stimulation therapy should be based on a close observation of patterns of behaviour, and, at least in deep coma stages, involve the registration of vegetative parameters. It may be sensitive to identify parameters predicting a favourable or unfavourable outcome. Preliminary data seem to support the hypothesis that the absence of any response to external stimuli is indicative of an unfavourable outcome.
