Purpose
The purpose of this study is to evaluate a noninvasive device to assess intracranial pressure wave form in children with hydrocephalus.
Methods
A prospective and non-experimental descriptive-analytic study was performed. Fifty-six patients were enrolled in this study. They were divided in four groups: group A, children with clinically compensated hydrocephalus; B, surgically treated hydrocephalus; C, patients with acute intracranial hypertension due to hydrocephalus; and D, children without neurological disease (control). Data were collected through the installation of an extracranial deformation sensor, coupled to the children’s scalp, which allowed registration of noninvasive intracranial pressure curves. Parameters obtained were analyzed: P2/P1 ratio, “classification P1 and P2 and P1 slope.
Results
P2/P1 index and “classification of P1 and P2” had a sensitivity of 80% and specificity of 100% for predicting intracranial hypertension. “P1 slope” presented no statistical difference.
Conclusion
This study showed a useful and noninvasive method for monitoring intracranial pressure, which was able to indicate the intracranial hypertension in children with hydrocephalus and, thus, should be further investigated for clinical applications.
