Filter by:This study aims to investigate the inner mechanism during different dehydration therapies such as mannitol injection and hypertonic saline. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to monitor the physiological changes noninvasively including oxyhemoglobin ([HbO2]), deoxy-hemoglobin ([Hb]), the derived change in blood volume ([tHb]) and water concentration on the forehead of brain edema patients.
The purpose of this study is to evaluate the change of the optic nerve sheath diameter after deflation of pneumatic tourniquet.
The aim of this study is to investigate any direct correlation between increased intrathoracic pressure, intraabdominal pressure and intracranial pressure, following a controlled elevation in intraabdominal pressure and intrathoracic pressure (PEEP). The second end-point is to investigate any correlation between elevated intracranial pressure and vasopressin release, urine output and urine and serum osmolality by measuring their values at different time-points.
Since decades, neurosurgeons and neurooncologists assumed that the mass effect of brain tumors with peritumoral edema or intratumoral hemorrhage might lead to increased ICP. Therefore, decisions on surgical procedures and medical treatments were made based on clinical and radiological findings suggesting increased ICP. But in fact, no measurement has ever confirmed increased ICP in brain tumor patients. From an ethical point of view, it is not justifiable to implant an intraparenchymal ICP probe within an invasive surgical procedure in a brain tumor patient unless the patient is comatose or present with rapid impairment of the level of consciousness. Therefore, with the new medical device for non-invasive ICP measurement presented in this study protocol, we will be able to measure absolute ICP values in patients with brain tumors.
The study is a prospective, multi-center, non-randomized, open label observational study. The objective of this study is to compare the accuracy of the EyeBOX to a clinical diagnosis of abnormal ICP as determined by an external ventriculostomy drain (EVD) or ventriculostomy catheter.
Severe Trauma Brain Injury (TBIs) is a public health problem and monitoring of Intracranial Pressure (ICP) is a determinant key of it prognosis. Within the noninvasive methods to estimate the ICP, the measurement of intraocular pressure has been proposed because of its biological plausibility (proximity of the eye to the encephalic contend). Objective. Correlate intraocular pressure with ICP in children with TBIs and obtain their utility values.
The purpose of this study is to evaluate the vision and posterior segment of eyes in children and young adults less than 22 years of age with risk, suspicion, or past medical history significant for elevated intracranial pressure (ICP). Patients will have visual acuity and color vision tested. Assessment of the posterior segment will involve using a non-invasive (non-contact) imaging technique (i.e. a portable fundus camera in clinic and hospital settings).
Primary objective of this study is to assess the accuracy and precision of intracranial pressure (ICP) measurement in patients after traumatic brain injury and subarachnoid hemorrhage when using simultaneous, non-invasive measurement compared to standard, invasive, measurement. Secondary objective: is to assess the correlation of intracranial pressure (ICP) measurement in patients after traumatic brain injury and subarachnoid hemorrhage between simultaneous, non-invasive measurement and standard, invasive,measurement
This is a single centre, observational study with a medical device which has Conformité Européenne (CE) marking. The aim of the study is to demonstrate that patients with malignant middle cerebral artery infarction (M-MCA) show an increased intra-cranial pressure (ICP) compared to neurological patients without M-MCA infarction or other space-occupying indications.
This study investigates the relationship between optic nerve sheath diameter and increased intracranial pressure and its effect on neurologic outcome in post-cardiopulmonary arrest patients.
