although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...

OBJECTIVE To assess the impact of intracranial pressure monitoring on the short-term outcomes of traumatic brain injury patients. METHODS Retrospective observational study including 299 consecutive patients admitted due to traumatic brain injury from January 2011 through July 2012 at a Level 1 trauma center in São Paulo, Brazil. Patients were categorized in two groups according to the measure...

conclusions although, the exact cause of pseudotumor cerebri in most individuals is unknown, but we should remind tuberculosis specially in endemic area for this infection. case presentation here, we presented a 14-year-old girl who referred to our hospital for fever, headache, vomiting and diplopia which has not respond to antibiotic therapy for acute meningitis. finally, with more evaluations...

OBJECTIVE Intracranial pressure monitoring is standard of care after severe traumatic brain injury. Episodes of increased intracranial pressure are secondary injuries associated with poor outcome. We developed a model to predict increased intracranial pressure episodes 30 mins in advance, by using the dynamic characteristics of continuous intracranial pressure and mean arterial pressure monitor...

OBJECTIVES To examine changes in cerebrovascular pressure transmission derived from arterial blood pressure (ABP) and intracranial pressure (ICP) recordings by autoregressive moving average modeling technique. METHODS Digitized ICP and ABP recordings were obtained from patients with brain injury. Two groups were defined: Group A with 4 patients who demonstrated plateau waves, and Group B with...

A fundamental requirement in the practice of medicine is having good instrumentation for the measurement of biological functions. In recent years, many new implantable sensors have been developed, capable to collect the data that is directly related to some health matter, [1]. Examples of such devices include pressure, temperature, and flow rate transducers. Subcutaneously implanted electronic ...

Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection. We tested how a proposed surrogate parameter for pulsatile intracranial pressure, the phase-contrast magnetic resonance imaging derived pulse pressure gradient, compared wit...

in recent years, the usefulness of intracranial pressure (icp) monitoring has been questioned in several reports for traumatic brain injury (tbi) management. therefore the needs of multidisciplinary groups of discussion of neurosurgeons and neurointensivists to update practical applications of icp in severe adult tbi has been advocated in many parts of the world. a consensus conference was held...
