Active clinical trials for "Emergence Delirium"

Postoperative delirium (POD) is a common postoperative complication that can occur in patients of any age. POD brings great burden to patients and their families, as the following cognitive decline may persist for months to years to impede patients returning to previous life quality and employment. The PREDICt study aims to characterize the incidence and profiles of POD in ICU, and to find out risk factors, especially any are modifiable, and any have value for developing prediction model. Our final aim is to comprehensively and deeply explore the etiology of POD to guide prevention of delirium among postoperative patients.

Introduction: Postoperative delirium (POD), an acute, transient, fluctuating disturbance in attention, cognition, and level of consciousness, is a common (15-53%) postoperative complication, and it is associated with longer hospital stays, worse functional outcomes, higher healthcare costs, and increased mortality. However, at the current time, effective prevention and treatment are not only hampered by lack of knowledge about the neuropathogenesis of POD but also by a lack of biomarkers that could predict individual risk and assess diagnosis and severity of POD. Recent studies have focused on inflammatory markers (IL-1, IL-6, IL-8, IL-10, CRP), Alzheimer's disease-related factors (Tau, Aβ40/42), and nerve injury factors (S100β, NSE), but failed to establishing causality between these markers and POD. Furthermore, these results were contradictory. Previous study of the investigators found that the dysregulation of preoperative microRNA (miR)-146a and miR-181c in cerebrospinal fluid (CSF) and serum was associated with the development and severity of POD. Therefore, the investigators hypothesized these neurimmiRs and other neuro-epigenetics biomarkers might participate in the neuropathogenesis of POD. Purpose: Aims to search for neuro-epigenetics biomarkers to predict and diagnose POD.

The project "QV-Delirium" is based on the decision of the Federal Joint Committee (G-BA) from 2017. The aim is to improve inpatient care for older patients who are undergoing inpatient surgery and thus to specifically reduce the postoperative risk of delirium. This is achieved through the implementation of evidence-based and consensus-based measures to prevent postoperative delirium in a comprehensive structured concept in routine care. The transparent documentation in an electronic patient file enables the relationships between the symptoms to be depicted in accordance with the clinical circumstances and the genesis of the postoperative delirium to be recorded and treated at an early stage.The independent Institute for Quality Assurance and Transparency in Health Care (IQTIG) receives the elements predefined (e.g. incidence of delirium) by IQTIG with which the quality is measured. The content of the additional elements from the routine data (see primary and secondary outcome measures) is merged internally and with BARMER and other health insurance data for a joint evaluation. Subproject 1: Preoperative evaluation of systolic and diastolic heart function in patients of the QV delirium cohort: In this process, this subproject relates to the evaluation of patients during the premedication visit. During the visit, an evaluation of the heart function using TTE should also take place in order to be able to evaluate later whether there is a association between the preoperative cardiac function examined and the development of postoperative delirium. The parameters to be collected are for the systolic heart function (LVEF, TAPSE, rest LV-SV and SVI, LVCO, LVCI LV / RV index, as well as for the diastolic dysfunction according to current recommendations (Nagueh SF et al., 2016) : MV DecT, MV E / A ratio, E'lat, E'sept, E ', E / E', IVRT-LV, S ', A', LAVI, tricuspid valve flow in tricuspid valve insufficiency: TR V max. Subproject 2 starts in April 2022: Anonymous quantitative employee (nurses and doctors) survey on the content of the quality contract with regard to employee satisfaction, feasibility, effectiveness, efficiency (cost-benefit balance), acceptance, needs, quality of the introduction, quality of the implementation.

The main objective is to assess the 6-month prognosis of patients who presented with extreme agitation in the emergency room. The primary endpoint is the 6-month mortality of agitated patients.

This international, multicentre prospective cohort study will assess whether perioperative duration and magnitude of mean arterial pressure (MAP) outside of an individual's cerebral autoregulation (CA) limits using near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) are associated with adverse neurological events. It is to investigate whether patients with a higher burden of cerebral haemodynamic insults have an increased incidence or poorer neurological outcomes. Associations between neurologic outcomes, neurobiomarkers and genetic tests will be explored.

Delirium is an acute brain lesion characterized by abnormalities of consciousness, attention, cognition and sensation. Many brain diseases such as stroke, traumatic brain injury and intracranial hypertension can lead to cardiac insufficiency, arrhythmia and heart failure. The incidence of postoperative delirium in patients undergoing cardiac surgery is high. Postoperative delirium is a manifestation of brain function injury. The effect of postoperative delirium on postoperative cardiac function in patients undergoing cardiac surgery is worthy of further discussion.

Aim of this trial is to define if Post-Operative Cognitive Dysfunction, detected analyzing changes between pre-operative and post-operative Neurocognitive Test, relate to concentration of effector's site concentration of propofol and remifentanil TCI and to the common intraoperative neuromonitoring values.

This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.

Emergence delirium is a significant problem, particularly in children. However the incidence, preventative strategies, and management of emergence delirium remain unclear. Multichannel electroencephalogram is a recognized tool for identifying neurophysiologic states during anesthesia, sleep, and arousal. The aim of the current study is to evaluate the mechanisms and predictors of emergence delirium in children under 16 years scheduled for elective surgery using electroencephalogram. The "Pediatric Anesthesia Emergence Delirium Scores (PAED Score)" (Sikich et al. 2004) is used to screen for the occurrence of emergence delirium in the post anesthesia care unit.

The goal of this randomized, double blinded study is to examine in children whether postoperative agitation can be reduced. The main question it aims to answer is Will optimized, monitor guided analgesic treatment and dexmedetomidine reduce postoperative agitation Participants will receive a standard anaesthesia regimen and on top of that, a titrable remifentanil infusion guided via Mdoloris Anastasia nociception index (ANI) monitor will be added. Additionally, the patients will receive either bolus placebo or bolus dexmedetomidine. The postoperative agitation measured via the Richmond agitation and sedation scale (RASS) score, will be compared. Secondary outcome measures including carbon dioxide trends will be made.
