Clinical Trial Summary

The purpose of this project is to determine during moderate rise of intracranial pressure (ICP) in awake patient, the change in autonomic function and its influence on cerebral and systemic haemodynamics.


Description:

From preliminary data, we know that changes in ICP influences both systemic and cerebral haemodynamics, introducing the concept of intracranial baroreflex We have to i) confirm the presence of this intracranial baroreflex, ii) analyze the changes in autonomic function during moderate rise in intracranial pressure (ICP) in human, and iii) correlate the changes in cerebral and systemic haemodynamics with autonomic function.

Intervention

Other:
Infusion
Infusion studies are performed in daily clinical routine to measure cerebrospinal fluid resistance outflow. During this test ICP is slowly and securely raised. Investigators plan to analyze what are the consequences of this ICP rise in terms of autonomic system and hemodynamics.
