[Test-provoked correlations between regional intracranial blood volume and intracranial pressure in infants during continuous simultaneous recording].

In a clinical study carried out in five infants with severe affections, provocation tests of different qualities were employed during the simultaneous recording of the intracranial blood volume (rICBV) and the intracranial pressure (ICP). The systematic use of a hydrostatic pressure test permits, among other things, to provide the theoretical basis for a statement of the volume/pressure response of the cerebrospinal fluid. Simultaneous measurements of rICBV and ICP enable a differenciated appraisal of the individually different critical points above which one must speak of a pathological ICP increase, with special importance being attached to the reactive hyperaemia and its prevention.
