Review[Continuous monitoring of brain electrical activity as a guide to treatment of acute brain lesion].
Cortical activity of the brain can be monitored continuously by simple, cheap and non-invasive methods. Nevertheless routine monitoring in Neuro ICUs seldom includes traditional or processed EEG. Our clinical experience with the Cerebral Function Monitor (CFM) indicates that a reliable guide to treatment of acute cerebral lesion can be obtained in different clinical situations and steps of management.

The camino ventricular bolt system has been used to monitor intracranial pressure in patients after severe head injury. The correlation between the ventricular pressure measured with the Camino device and an external transducer showed that the Camino accurately measured intracranial pressure over a wide range, but that it read an average of 1.15 mm Hg higher than that obtained by the external transducer. The technique has the advantage over a remote transducer because it is sited within the ventricle. This may be of value in wave-form analysis.

Comparative Study99mTc-HMPAO SPECT of the brain in mild to moderate traumatic brain injury patients: compared with CT--a prospective study.
Single photon emission computed tomography (SPECT) with Technetium-99m hexamethyl propylenamine oxime (Tc-99m-HMPAO) was used in 20 patients with mild to moderate traumatic brain injury (TBI) to evaluate the effects of brain trauma on regional cerebral blood flow (rCBF). SPECT scan was compared with CT scan in 16 patients. SPECT showed intraparenchymal differences in rCBF more often than lesions diagnosed with CT scans (87.5% vs. 37.5%). ⋯ All these patients with fractures had normal brain on CT scans. Conversely, extra-axial lesions and fractures evident on CT did not visualize on SPECT, but SPECT demonstrated associated changes in rCBF. Although there is still lack of clinical and pathological correlation, SPECT appears to be a promising method for a more sensitive evaluation of axial lesions in patients with mild to moderate TBI.

Review
[Management of the patient with craniocerebral injuries at the accident site and clinic admission].
Between January 1991 and December 1992, there were 686 rescue operations involving patients with craniocerebral trauma in the catchment area of Ulm. There were 376 patients who had to be graded as seriously injured according to the NACA classification. In 178 cases there was a severe craniocerebral trauma, and 131 of these patients were admitted to the traumatology department of the University of Ulm. ⋯ Diagnostic procedures and immediate treatment must initially be directed at securing vital functions. Treatment of life-threatening haemorrhage has priority over neurosurgical diagnosis and therapy. The urgent indications for neurosurgical intervention are: space-occupying intracranial bleeding, open craniocerebral traumas, and space-occupying depressed fractures.

The mortality rate after traumatic brain injury in children ranges between 2.5% and 21%. Standardized diagnostic procedures and therapeutic strategies for the management of traumatic brain damage are presented in this article. Children with traumatic cerebral lesions have a better clinical outcome than head-injured adults. Optimized medical management and intensive rehabilitation may help to reduce the frequency of mental retardation and physical disability following such injuries in children.
