We evaluated postural effects on intracranial pressure (ICP) and cerebral perfusion pressure [CPP: mean arterial pressure (MAP) - ICP] in neurosurgical patients undergoing 24-h ICP monitoring as part of their diagnostic workup. We identified nine patients (5 women, age 44 ± 20 yr; means ± SD), who were "as normal as possible," i.e., without indication for neurosurgical intervention (e.g., focal...

ICP on assessment and monitoring of acidification of rivers and lakes (ICP Waters) ICP on effects of air pollution on materials, including historic and cultural monuments (ICP Materials) ICP on effects of air pollution on natural vegetation and crops (ICP Vegetation) ICP on integrated monitoring of air pollution effects on ecosystems (ICP IM) ICP on modelling and mapping of critical levels and ...

BACKGROUND We recently reported that in an experimental setting the zero pressure level of solid intracranial pressure (ICP) sensors can be altered by electrostatics discharges. Changes in the zero pressure level would alter the ICP level (mean ICP); whether spontaneous changes in mean ICP happen in clinical settings is not known. This can be addressed by comparing the ICP parameters level and ...

introduction measuring magnetic induction phase shift (mips) changes as a function of cerebral hemorrhage volume has the potential for being a simple method for primary and non-contact detection of the occurrence and progress of cerebral hemorrhage. our previous mips study showed that the intracranial pressure (icp) was used as a contrast index and found the primary correlation between mips and...

In children with craniosynostosis, raised intracranial pressure (ICP) and upper airway obstruction (UAO) are both common features. However, potential interactions between UAO and ICP during sleep are poorly understood. The aim of the present study was to compare the levels of ICP during sleep between a group of patients with syndromic craniosynostosis (with facial involvement and consequent UAO...

Management of intracranial hypertension is a major cornerstone of neurocritical care. Apart from traumatic brain injury, there are no clear guidelines for intracranial pressure (ICP) monitoring. The insertion of ICP monitors is an invasive procedure with inherent risks and could be contraindicated in case of severe coagulopathy. The transcranial Doppler (TCD) pulsatility index (PI) has emerged ...

INTRODUCTION Increased ICP is common and might precipitate cerebral vasospasm (VSP)-induced ischemic events in aneurysmal SAH (ASAH).Our objective was to determine if there is an association between increased ICP and transcranial colour coded Doppler-angiographic VSP (TCCD-A VSP) in relation to delayed neurological deficit (DND) and poor outcome. METHODS A retrospective study was undertaken i...

OBJECTIVE This study evaluates the value of continuous dynamic monitoring of intracranial pressure (ICP) in patients with hypertensive intracerebral hemorrhage to predict early postoperative complications. PATIENTS AND METHODS Data from 80 patients treated in our hospital from February 2014 to February 2015 were analyzed. The patients all underwent decompressive craniectomies, and their ICP c...

BACKGROUND Studies in traumatic brain injury suggest that monitoring techniques such as brain tissue oxygen (P(BTO₂)) and cerebral microdialysis may complement conventional intracranial pressure (ICP) and cerebral perfusion pressure (CPP) measurements. OBJECTIVE In this study of poor-grade (Hunt and Hess grade IV and V) subarachnoid hemorrhage (SAH) patients, we examined the prevalence of bra...

OBJECT Intracranial pressure (ICP) monitoring is used extensively in clinical practice, and as such, the accuracy of registered ICP values is paramount. Clinical observations of nonphysiological changes in ICP have called into question the accuracy of registered ICP values. Subsequently, the authors have tried to determine if the ICP monitors from major manufacturers were affected by electrosta...
