Comparative StudySomatosensory evoked potentials for prediction of outcome in acute severe brain injury.
The purpose of this study was to evaluate prospectively short-latency somatosensory evoked potentials (SEPs) as a predictor of outcome in acute, severe brain injury, and to compare this with the predictive power of the motor component of the Glasgow Coma Scale score and computed tomographic scan. Outcome was measured with the Glasgow Outcome Scale at a minimum of 6 months after injury. We studied 109 patients (aged 0.1 to 16.8 years) with SEPs within 4 days of the onset of coma. ⋯ Of the 59 patients with unfavorable outcome, 76% could be identified with SEPs compared with 36% with examination of motor function. We suggest that SEPs be performed in children with acute severe brain injury because they add an important tool to the physician's prognostic armamentarium. We conclude that in the absence of the above mentioned identifiable clinical situations, absent SEPs predict 100% unfavorable outcome, and this finding may warrant consideration of withdrawal of treatment in children with brain injuries.

Posttraumatic agitation is perhaps the most dramatic behavioral consequence of severe traumatic brain injury. The mechanism for this behavior remains to be determined. ⋯ Concurrent neurologic or medical decline during the recovery from an acute traumatic brain injury may precipitate delirium, which has many clinical features that overlap with posttraumatic agitation. Hence, the differential diagnosis of posttraumatic agitation includes all medical and neurologic etiologies for transient declines in consciousness and cognition.

The Glasgow Coma Scale is probably the most common grading scale in neurotraumatology all over the world. Its validity concerning severity and prognosis of the injury has been established in the Anglo-American literature. Data derived from the German rescue system, however is different from the Anglo-American in some respects. ⋯ Especially for the best Glasgow Coma Score during the day after the injury, GCS 4 had a poorer collective long-term prognosis than GCS 3. Therefore, German data from head injury studies based on the Glasgow Coma Scoring are difficult to compare to those cited in the Anglo-American literature. Any statistical analysis of a so called "ranking scale" which does not satisfy its own claims under special conditions is difficult.

CT and clinical criteria for conservative treatment of supratentorial traumatic intracerebral haematomas.
In search of guidelines for the management of traumatic intracerebral haematomas (TICHs) with slight mass effects on computed tomography (CT) scans, the author reviewed the records of 29 patients who did not undergo surgery and 11 patients who did. It is found that patients with a TICH volume of less than 15 ml, a midline shift of less than 5 mm, an open perimesencephalic cistern on CT scans, a Glasgow Coma Scale (GCS) score of 12 or more, and an absence of lateralizing signs may be treated conservatively and expected to make a good recovery. On the other hand, with zero mortality and satisfactory outcomes, the patients under-going early surgery tended to have a TICH volume of more than 15 ml, a midline shift of more than 5 mm, an obliterated perimesencephalic cistern on CT scans, a GCS score of less than 12, and the presence of lateralizing signs. However, the position of such features as the criteria of early operation for a TICH is weakened by the retrospective nature of this study because some surgical patients, free of lateralizing signs in particular, might have managed to do well without craniotomy.
