INTRODUCTION Many brain processes that cause death are mediated by intracranial hypertension (ICH). The natural course of this condition inevitably leads to brain death. The objective of this study is to carry out a systematic review of cerebral pathophysiology and intracranial pressure (ICP) monitoring. DEVELOPMENT Studying, monitoring, and recording ICP waves provide data about the presence...

BACKGROUND During an endoscopic neurosurgical procedure a sudden increase in intracranial pressure may occur at any time. We present a prospective study of haemodynamic changes during such procedures. METHODS Physiological data were recorded during the whole operative procedure in 17 consecutive patients who underwent an endoscopic neurosurgical procedure under general anaesthesia. Monitoring...

Background Continuous electroencephalography (CEEG) monitoring is used for detection of convulsive and nonconvulsive seizures and assessing the degree of encephalopathy in critically ill patients. A commonly seen encephalopathic pattern on CEEG is generalized periodic discharges with triphasic wave (TW) morphology. The underlying role and prognostic significance of TW in relationship to intracr...

in this article, dynamics of the cerebrospinal fluid (csf) was studied, using computational fluid dynamics. using mri images of two special cases, a 2-dimensional model of the ventricular system was made. csf velocity and pressure distribution in ventricular system have high importance since the flow pattern of this liquid has an important effect on intracranial pressure, i.e., icp, which has a...

This review paper describes innovative methods and technology for non-invasive human brain physiological monitoring based on measuring the acoustic properties of the brain parenchyma. The clinical investigation of new technology shows the similarity between the invasively recorded intracranial pressure (ICP) and non-invasively recorded intracranial blood volume (IBV) pulse waves, slow waves and...

Intracranial pressure (ICP) is highly predictive of outcome in traumatic brain injured (TBI) patients with the proportion of hourly ICP greater than 20mmHg being a significant independent determinant of outcome [1-4]. The objective of such monitoring is to maintain adequate cerebral perfusion and oxygenation so as to avoid secondary insult to the traumatically injured brain. Furthermore, prophy...

BACKGROUND It has been suggested that a moving correlation index between mean arterial blood pressure and intracranial pressure, called PRx, can be used to monitor and quantify cerebral vasomotor reactivity in patients with head injury. OBJECTIVES To validate this index and study its relation with cerebral blood flow velocity and cerebral autoregulation; and to identify variables associated w...
