[Penetrating craniocerebral injury]. / Die penetrierende Schädel-Hirn-Verletzung.

Through a ten-year period, treatment was applied to 145 patients for open craniocerebral injuries in the calottal region. Mortality amounted to 35 per cent and postoperative infections to 16 per cent. Early or, in cases of intracranial invasive growths, immediate surgery with purpose-oriented osteoplastic trepanation is the optional method.

[Lactate concentration in the ventricular fluid and blood plasma following severe craniocerebral trauma]. / Laktatkonzentration im Ventrikelliquor und Blutplasma nach schwerem Schädel-Hirn-Trauma.

Cerebral ischemia/hypoxia is of central importance in the sequence of pathogenetic processes after severe head injuries. Investigations in 72 patients showed that after severe head injury the changes of lactate concentration in blood plasma do not allow any statement with respect to cerebral ischaemia/hypoxia. However in ventricular liquor the amount and duration of increase in lactate concentration is significantly different in nonsurvivors in comparison to survivors. In lethal courses after 3rd day after head injury the increase of lactate concentration in ventricular liquor points to secondary cerebral ischemia/hypoxia.
