Ultrasound as a non-invasive diagnostic tool in paediatric neurosurgery : relationship between the optic nerve sheath diameter (ONSD) and intracranial pressure (ICP)
Background: Assessment of intracranial pressure (ICP) is an essential aspect in the management of most neurosurgical conditions in children. While invasive ICP monitoring is considered the criterion standard, the need for a reliable, non-invasive, easy-to-use and accurate method to detect and …

Decompressive craniectomy in children with traumatic brain injury
… therapy failed in the treatment of raised intracranial pressure (ICP), two important concepts have emerged in the recent literature that appear to challenge that approach. In addition to the lack of evidence supporting benefit from current forms of treament, evidence from diverse studies …

Frequency domain model-based intracranial pressure estimation
Elevation of intracranial pressure (ICP), the pressure of the fluid surrounding the brain, can require urgent medical attention. Current methods for determining ICP are invasive, require neurosurgical expertise, and can lead to infection. ICP measurement is therefore limited to the sickest …

An embedded device for real-time noninvasive intracranial pressure estimation
Monitoring of intracranial pressure (ICP) is key in many neurological conditions for diagnosis and guiding therapy. Current monitoring methods are highly invasive, limiting their use to the most critically ill patients. Based on a previously developed approach to noninvasive ICP estimation from …

Impact of secondary insults on the outcome of paediatric traumatic brain injury : a retrospective cross sectional study at the Red Cross Children’s Hospital, Cape Town
… example, despite the known association between intracranial pressure (ICP) and poor outcome, there are few large paediatric series on the subject, definitions vary, functional outcome is often not assessed, and the best measures to assess ICP for statistical analysis are unknown. We aimed to …

The effect of induced normothermia on the outcomes of severe traumatic brain injury patients at Boston Medical Center
… those in the control group (p = 0.0001). Average intracranial pressure (ICP) and cerebral perfusion pressure (CPP) were not different between the two groups, although mean arterial pressure (MAP) was (p = 0.84; p = 0.08; p = 0.02, respectively). Mortality was lower in the case group by hospital …

Obesity, 11β-hydroxysteroid dehydrogenase and metabolic changes in the pathogenesis of idiopathic intracranial hypertension
Idiopathic intracranial hypertension (IIH) is a blinding condition amongst the young obese female population characterised by elevated intracranial pressure (ICP). The aetiology of IIH is not known and, as highlighted in the 2005 Cochrane review, an evidence base for treatment has not been …

A pseudo-Bayesian model-based approach for noninvasive intracranial pressure estimation
A noninvasive intracranial pressure (ICP) estimation method is proposed that incorporates model-based estimation within a probabilistic framework. A first-order subject-specific model of the cerebral vasculature relates arterial blood pressure with cerebral blood flow velocity. The model is solved …

Process of Care and Outcome of Critically Ill Patients with Traumatic Brain Injury
… First, I evaluated the association between intracranial pressure (ICP) monitoring use and mortality after severe TBI at the patient-level and at the hospital-level. ICP monitoring use was associated with lower mortality at the patient-level [adjusted odds ratio (OR) was 0.44; 95% confidence …

A spectral approach to noninvasive model-based estimation of intracranial pressure
Intracranial pressure (ICP) is the hydrostatic pressure of the cerebrospinal fluid. Ideally, ICP should be monitored in many neuropathological conditions, as elevated ICP is correlated with poor neurocognitive outcomes after injuries to the brain. Measuring ICP requires the surgical placement of a …

Mathematical Model for Hemodynamic and Intracranial Windkessel Mechanism
The understanding of intracranial system so that one can explain its related pathological condition such as hydrocephalus and traumatic brain injury (TBI) is still subtle. Especially, the cause of hydrocephalus which is known as the common birth defect is not well defined. Traditionally, …

Transorbital ultrasound measurement of the optic nerve sheath diameter (ONSD) as a screening tool for raised intracranial pressure in an acute care setting in children
… be challenging. Early and reliable diagnosis of intracranial pressure (ICP) in children following TBI is vital in optimizing outcome. Clinical findings of raised ICP can be non-specific and are often missed in minor injuries, leading to severe consequences. The use of a simple, quick, accurate, …

Investigating the effects of acute intracranial pressure and brain oxygenation on neuropsychological outcomes 12 months after severe pediatric traumatic brain injury
… between acute stage physiological changes in intracranial pressure (ICP) and brain tissue oxygenation (PbtO2) and neuropsychological outcomes one year after pTBI. Results of the study indicated that children who sustained TBI performed significantly poorer than healthy, matched controls on …

AUTOMATED MIDLINE SHIFT DETECTION ON BRAIN CT IMAGES FOR COMPUTER-AIDED CLINICAL DECISION SUPPORT
… medical decision making is to estimate the intracranial pressure (ICP). ICP monitoring is a standard procedure in the care of severe traumatic brain injury (TBI) patients. An automated ICP level prediction model based on machine learning method is proposed in this work. Multiple features, …

A spectral approach for noninvasive estimation of intracranial pressure
Intracranial pressure (ICP) is an important clinical indicator of neurological injury and is used in the diagnosis, treatment and monitoring of several neurological pathologies. Current measurement modalities of ICP are highly invasive, largely limiting the measurement to critically ill patients. …

The Effect of Oral Care on Intracranial Pressure in Critically Ill Adults
… is to prevent or minimize episodes of increased intracranial pressure (ICP). Elevations in ICP in response to nursing interventions have been acknowledged since the 1960’s when ICP monitoring was first introduced in the clinical setting. Until recently few studies have specifically examined the …

Automated Measurement of Midline Shift in Brain CT Images and its Application in Computer-Aided Medical Decision Making
… in pathological cases and use it to predict Intracranial Pressure (ICP). The midline shift measurement can be divided into three steps. First the ideal midline of the brain, i.e., the midline before injury, is found via a hierarchical search based on skull symmetry and tissue features. …

Effect of head elevation on intracranial blood flow velocity following acute ischemic stroke

A repeated measures quasi-experimental design was used to study the effect of 30, 15, and 0 degree HOB elevation on middle cerebral artery (MCA) mean flow velocity (MFV) in a convenience …

Multilayer network methodologies for brain data analysis and modelling
… data were collected from the observations of IntraCranial Pressure (ICP) and Heart Rate (HR). We first detected events of simultaneous increase of HR and ICP, which we called brain-heart crosstalks. Subsequently time series were translated into graphs, and network measures, during brain-heart …
