Brief Summary:
The aim of this study is to determine whether we can predict the intracranial pressure using near infra-red spectroscopy

Condition or disease
Intracranial Hypertension

Detailed Description:

The management of intracranial hypertension requires the presence of an intracranial pressure monitor. We are investigating whether the waveforms obtained from a near infrared spectroscopy device can predict what the intracranial pressure is non-invasively.

  • Patients with intracranial hypertension who are intubated and ventilated in the ICU will be recruited
  • we will record there intracranial pressure and systemic arterial pressure
  • recordings from the near infrared device will be recorded and analysed off-line
  • we will correlate the waveform tracings from near infrared spectroscopy and the arterial tracing

Study Type : Observational
Estimated Enrollment : 59 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Use of Near Infrared Spectroscopy (NIRS) to Estimate Intracranial Pressure (ICP)
Study Start Date : June 2014
Estimated Primary Completion Date : June 2017
Estimated Study Completion Date : June 2017

Group/Cohort
Intracranial hypertension
Patients with raised intracranial pressure



Primary Outcome Measures :
  1. Intracranial elastance [ Time Frame: Participants will be followed while an arterial line and intracranial pressure monitor is present duing the ICU admission. This is expected to be an average of 5 days. ]
    Intracranial elastance (δP/δV)will be measured by dividing the pulse pressure of an invasive arterial blood pressure by the amplitude of high frequency oscillations in the near infrared (NIR) absorbance waveforms.
