NCT ID: NCT06368648 Not yet recruiting - Stroke Clinical Trials

CoMind Early Feasibility Study

CoMind EFS
Start date: June 2024
Phase:
Study type: Observational

The purpose of this research, which has been determined as non-significant risk by the central IRB overseeing the study, is to obtain information to help further develop a machine (a medical device) to measure the pressure around the brain from the outside (this pressure is called intracranial pressure or ICP). Monitoring and managing ICP is an important part of care for patients with conditions such as Traumatic Brain Injury (TBI). However, the current way of measuring ICP requires surgery to drill a hole into the skull, and therefore can introduce additional risks such as infections and pain. Recent research has shown it may be possible to measure ICP without needing surgery. This technology is in development, but large amounts of data is required to build these new devices. Through collecting a large database of information from patients who have both the routine surgical device and the research device applied to their head, the research team will work to develop and test an effective and potentially safer way of monitoring patient ICP.

NCT ID: NCT06101537 Recruiting - Clinical trials for Subarachnoid Hemorrhage

Correlation Patterns of Brain Temperature-Pressure in Acute Brain Injury

MERCURY
Start date: February 15, 2024
Phase:

The goal of this prospective, multicenter, observational, cohort trail is to explore the pattern of brain temperature-brain pressure association in acute brain injury and to clarify its predictive value for prognosis and neurological function 30 days after acute brain injury.

NCT ID: NCT06027567 Recruiting - Obesity Clinical Trials

The Effect of an Anti-obesity Drug, Semaglutide, as Treatment in New-onset Idiopathic Intracranial Hypertension (IIH) Compared to Standard Weight Management (Dietician) With Regards to Change in Weight and Intracranial Pressure

IIH:DUAL
Start date: September 2, 2022
Phase: Phase 4
Study type: Interventional

50 patients with verified new-onset Idiopathic Intracranial Hypertension are randomly allocated to standard weight management (dietician counselling) or trial intervention consisting of subcutaneous injections with Semaglutide for 10 months combined, in the initial 8 weeks following diagnosis, with a Very Low Calorie-Diet (max 800 kcal/day)

NCT ID: NCT05501613 Completed - Critically Ill Clinical Trials

Early Multimodal Neuromonitoring For Spontaneous Intracerebral Hemorrhage (ICH)

Start date: January 2015
Phase:
Study type: Observational

The investigators intend to assess the predictive value of early (first 48 hours) multimodal neuromonitoring parameters concerning late survival in critically ill intracerebral hemorrhage (ICH) patients.

NCT ID: NCT05068128 Active, not recruiting - Dementia Clinical Trials

Combined Flow and Pressure Study of Craniospinal Dynamic

REVERT
Start date: September 1, 2021
Phase:
Study type: Observational

Normal pressure hydrocephalus (NPH) can cause a type of dementia. However, this type of dementia is the only one that is reversible. To treat this dementia it is necessary to evacuate the accumulation of CSF from the brain to another body cavity using a device called a shunt. But the implantation of this shunt is only effective when the cause of the pathology is an alteration of the normal circulation of the CSF. To diagnose these patients, morphological MRI and lumbar puncture are standard approaches used but remain perfectible in diagnostic terms. The main objective is to build a new model of the interaction of intracranial pressures and fluids in order to obtain a new parameter allowing to obtain information on the cerebral biomechanics.

NCT ID: NCT04910087 Recruiting - Propofol Clinical Trials

The Effect of Anesthesia Management on Optic Nerve Sheath Diameter in the Ercp Procedures

Start date: June 1, 2021
Phase: N/A
Study type: Interventional

Aim: To compare the effect of procedural anesthesia management with ketofol and propofol on the sonographic optic nerve sheath diameter in the endoscopic retrograde cholangiopancreatography (ERCP) procedures.

NCT ID: NCT04861402 Recruiting - Clinical trials for Intracranial Pressure

Non-Invasive Intracranial Pressure in COVID-19 Individuals

Start date: April 30, 2020
Phase:
Study type: Observational

The use of non-invasive intracranial pressure monitoring, including intracranial pressure pulse morphology in patients with COVID-19, could calculate possible components associated with the presence of neurological symptoms in these patients, in addition to being a tool with the potential to monitor the repercussion of MV at cerebral compliance patient patients. In addition, it is likely that patients with COVID-19 also have cerebral embolization more frequently than healthy patients, which is justified by transcranial doppler ultrasound assessment. The aim of the study is to monitor this brain pressure using a non-invasive method of monitoring, with a helmet-like system in place, for 1 hour for 7 consecutive days. There will be no associated invasive procedure of any kind. Monitoring will be done by the criteria themselves, no place where the patient and the mandatory volunteer. Another objective is to capture signs of microembolisms (small strokes that have not yet manifested) by performing a doppler ultrasound on the head with a helmet also for 1 hour, in a single evaluation. The study population will include inpatients with COVID-19 infection. The control group will be in patients who do not have Covid-19. The control group will consist of people with similar characteristics and who have not recovered. Patients who meet the inclusion criteria incorporated into the monitoring with a non-invasive intracranial pressure device for 1 hour during hospitalization (Brain4Care® device approved by ANVISA), being monitored for up to seven days, in addition to monitoring for 1 hour with a transcranial doppler ultrasound helmet DWL® in a single assessment. There will be no invasive procedures or other equipment used without due knowledge by Organs competent bodies. It does not collect collection or retention of any biological material.

NCT ID: NCT04849221 Completed - Clinical trials for Intracranial Pressure

Wideband Tympanometry for Monitoring Intracranial Pressure in Adult Patients in Intensive Care, Operated on for an Intracranial Lesion After Traumatic Brain Injury, or With Intracranial Hemorrhage

TYMPIC
Start date: March 4, 2021
Phase:
Study type: Observational

Intracranial pressure is usually measured by invasive methods requiring an intracranial sensor. There is no non-invasive monitoring method recognized as a gold standard. Tympanometry would make it feasible to evaluate intracranial pressure through sensitive and specific changes in the energy absorbance of the middle ear. It could represent a non-invasive method of monitoring intracranial pressure. This is a prospective monocentric longitudinal study. All adult patients in intensive care for head trauma, intracranial hypertension, or after cranial surgery and requiring invasive monitoring of ICP will be included after their non-opposition has been collected. In a group of 10 controls, multifrequency tympanometry will be performed in the standing position, in the 0° supine position and in the Tredelenburg position at -17°.

NCT ID: NCT04288076 Withdrawn - Clinical trials for Mechanical Ventilation

The Brain and Lung Interaction (BALI) Study

Start date: September 2020
Phase: N/A
Study type: Interventional

The purpose of this study is to understand the relationship between intracranial pressure and airway pressures during mechanical ventilation. This study is a single-center, prospective cohort study to be conducted at Beth Israel Deaconess Medical Center. The investigators will recruit patients with severe brain injury (GCS 8 or less) who receive intracranial pressure monitoring and mechanical ventilation as part of their routine medical care. The primary endpoint is the change in intracranial pressure as a function of positive end-expiratory pressure. There is only one study encounter with safety monitoring for up to 24 hours after. No additional follow up is required.

NCT ID: NCT03938402 Terminated - Clinical trials for Intraocular Pressure

Intraocular Pressure and Optic Nerve Sheath Diameter Changes at Different PEEP Levels

Start date: July 1, 2019
Phase: N/A
Study type: Interventional

Positive end-expiratory pressure (PEEP) is sometimes used during perioperative period, as it has favourable effects on lung mechanics. Unfortunately, it has some negative effects on the patients, like increased intraabdominal, intrathoracic, intracranial and intraocular pressures. In this study the investigators aimed to investigate the effects of different PEEP levels on the patients' intraocular and intracranial pressures. Intraocular pressure will be measured by ocular tonometry, and intracranial pressure will be estimated by optic nerve sheath diameter measurement. The measurements will be performed in the operating room in the patients undergoing laparotomic surgery.
