Abstract
Since 1982, 23 hydrocephalic children have been studied for compensatory mechanisms of the cerebrospinal fluid system. The authors describe the method and results of a computerized pressure-elastance resorption test (CPERT), a spinal steady-state infusion test, in hydrocephalic children. Computerized analysis of the P/V and AMP/P curve provides valuable data that precisely describe the degree of disturbances of CSF dynamics. The following parameters were quantitatively determined: outflow resistance, opening pressure, elastance, elastivity, reference pressure and optimum (break-point) pressure. It is concluded that the described test allows the differential diagnosis of chronic hydrocephalus in children. The value of optimum pressure (analysis of AMP-P relation) gives precise indications for surgery and the selection of a valve system with adequate opening pressure. In some cases, the CPER test can be used instead of continuous ICP monitoring.
