Filter by:This is the first and only study conducted on the use of capnography in children diagnosed with DKA to evaluate the initial clinical grading of DKA, monitor clinical improvement, and predict complications such as brain edema.
To establish a predictive model and scoring system for predicting severe complications after thrombectomy. This scoring system can be used to identify high-risk patients after endovascular thrombectomy, guide the early use of adjunctive interventions, and provide reference for future clinical trials.
The goal of this observational study is to compare the differences in the features of cerebral multifrequency EIT(cMFEIT) images between healthy subjects and patients with brain diseases and to explore the possibility of applying multifrequency EIT to intracranial abnormality detection.16 healthy volunteers and 8 patients with brain diseases were recruited as experimental subjects, and the cerebral EIT data of 9 frequencies in the range of 21 kHz - 100 kHz of all subjects were acquired with an EH-300 MFEIT system.
This is a single-center, randomized, double-blind, placebo-controlled Phase I clinical study to evaluate the tolerability, safety, and pharmacokinetic characteristics of SIM1910-09 for injection after single/multiple dosing in healthy Chinese adult volunteers.
Rheoencephalography (REG) shows promise as a method for noninvasive neuromonitoring, because it reflects cerebrovascular reactivity. This protocol will study clinical and technical conditions required to use REG. Additionally, our goal is to study noninvasive peripheral bioimpedance pulse waveforms in order to substitute invasive SAP. A previous study demonstrated that REG can be used to detect spreading depolarization (SD), the early sign of brain metabolic disturbance. SD can be measured invasively with DC EEG amplifiers only. Our goal is to create an automatic notification function for REG monitoring indicating change of clinical conditions.
The study will examine the resting energy need (REE) in patients suffering from brain damage. For the measurement of REE will be used a metabolic computer (which with continuous recording of breath-to-breath volume (Vt), respiratory rate (RR) of ventilation per minute volume (MV) ), of inhaled and exhaled gases (O2 and CO2) has the ability to calculate the values of VO2, VCO2 and with the help of equations the values of REE and RQ.
Patients with chronic kidney disease (CKD) with criteria for renal replacement therapy (RRT) including uremic syndrome, have a stable state of hyperosmolarity due to urea despite not being an osmotically inactive ion. Also, these patients have alterations in urea transporters in the central nervous system (CNS) conferring a risk of neurological involvement due to an abrupt decrease in serum urea causing manifestations of the post-dialytic syndrome. Hemodialysis results in rapid removal of urea from the blood, much faster than the equilibrium rate between the brain and the bloodstream through the blood-brain barrier, resulting in an osmotic gradient that favors movement from water to the brain, causing cerebral edema, intracranial hypertension and dialysis-associated imbalance syndrome. Conventional hemodialysis (HD) uses diffusion and primarily decreases small solutes, while hemofiltration (HF) is based on convection that provides clearance mainly of medium-size molecules and small solutes with a slower rate of reduction.
The most common tool for diagnosis and follow up of cerebral edema in ICU is brain CT scan that necessitate patient transportation with risk of hemodynamic instability, and exposure to radiation. Transcranial Doppler (TCD) sonography allows true and rapid imaging of blood flow velocities of intracranial vessels. Transcranial Doppler sonography provides noninvasive evaluation of intracranial pressure by its characteristic wave patterns
Aim: The investigators aim to evaluate the effect of lumbar cerebrospinal fluid (CSF) drainage on neurologic outcome in post-cardiac arrest (CA) patients treated with target temperature management (TTM). Methods: This is a prospective single-center study conducted from May 2020 to November 2021 on patients who have been treated with TTM following CA. The propensity score matching is proceeded between the lumbar CSF drainage and non-lumbar CSF drainage groups. The good outcome group is defined as a Glasgow-Pittsburgh cerebral performance categories (CPC) scale 1 or 2, and the poor outcome group as a CPC between 3 and 5. Lumbar CSF drainage is initiated when intracranial pressure (ICP) exceeded 15 mmHg in the absence of noxious stimuli at the rate of 10~20 ml/h via a lumbar drainage catheter until ICP is less than 15 mmHg. The magnetic resonance imaging (MRI) is obtained between 72-96 h after return of spontaneous circulation (ROSC) to evaluate the effect of lumbar CSF drainage on attenuation of brain swelling through quantitative analysis of apparent diffusion coefficient (ADC). Multivariate logistic regression and Kaplan-Meier models are built to identify the effect of CSF drainage on the neurologic outcome improvement.
Literature reports the development of brain oedema following the use of certain drugs. Therefore, this study aims to present a comprehensive disproportionality analysis of brain oedema cases reported to the Food and Drug Administration Adverse Event Reporting System (FAERS).
