Active clinical trials for "Delirium"

Methodology: Pilot randomized controlled trial with 1 intervention and 1 parallel standard care group to assess the feasibility and treatment effect of a multimodal integrative intervention for delirium prevention and associated detrimental effects. Duration: 2 years, two months. Study Center(s): Multi-center (2 sites) Aim: To assess feasibility and measures of effect of a multimodal intervention consisting of relaxation with guided imagery (RGI), and moderate pressure massage on physiological and psychological outcomes of critically ill patients. Objectives: a) assess clinical trial feasibility with pre-defined goals (enrollment, randomization, adherence, timing of intervention, workload), b) calculate estimates and variance of treatment effect across outcome measures, c) calculate confidence intervals (CI) of incidence proportions, means and standard deviation (SD) of outcome measures in study groups., d) explore underlying physiological mechanisms of efficacy Number of Subjects: 60 participants per arm. Total: 120 participants Diagnosis and Main Inclusion Criteria: Critical illness Inclusion criteria: a) Age over 18 years, b) ICDSC:0-3. Exclusion Criteria: Patients: a) with expected ICU LOS< 72 hours, b) with acute neurological illness/ trauma, persistent sedation or coma, c) with current history of severe mental health problems and dementia, as per history and psychiatrist assessment, c) with hearing impairment or conditions not permitting use of headphones, e) on neuro-muscular blockers, f) with substance/ alcohol withdrawal, g) enrolled in trials of sedatives, antipsychotics. Intervention: REPOSE intervention (a multimodal relaxation intervention) It includes: a) relaxation and guided imagery (RGI) (40 min, headphones), b) a brief moderate pressure massage session (massage: 15 min). RGI involves: a) guided relaxation, b) a structured guided imagery script and c) music for 15 min (Mozart piano sonata KV283, G major (2 3) II Andante). Duration of administration: Up to 5 days while participants still in the ICU. Reference therapy: Standard care plus placebo to maintain blinding. Statistical Methodology: Outcomes will be analyzed longitudinally over 5 days by logistic regression model based on generalized estimating equations (GEE) with AR(1) correlation structure. Confidence intervals will be presented with estimated effects. Primary analysis will be based on all available data utilizing data from all assessments.

Parallel group, prospective, randomized, controlled, single-blinded trial. The aim of our study is to test the hypothesis that volatile anesthesia would reduce the incidence of early postoperative delirium in patients undergoing cardiac surgery with CPB as compared to TIVA.

Bladder cancer is one of the most common genitourinary cancers. Transurethral resection of bladder tumor (TURBT) is the standard therapy for nonmuscle invasive bladder cancer. However, patients after TURBT are at risk for recurrence and progression. Benzodiazepines are proved to inhibit proliferation of multiple types of cancer cells in vitro. Delirium is an acute onset and transient cerebral dysfunction and is associated with worse outcomes. Previous studies indicated that benzodiazepines increase incidence of postoperative delirium. Remimazolam is a new benzodiazepine with rapid onset and ultra-short activity. The aims of this study are to explore the impact of remimazolam for general anesthesia on emergency delirium and recurrence-free survival in patients undergoing bladder cancer surgery.

Cardiac surgery is not trivial. It requires opening the thorax in certain indications: coronary artery bypass grafting, valve replacements or plasties, aortic dissection, etc. These different procedures, both pre- and post-op, generate anxiety in the patient, the effects of which can be harmful to the recovery process and general well-being. It can be increased by the resuscitation environment during the immediate postoperative management. This environment also favors the development of delirium. It is possible to improve this environment by using non-drug and inexpensive techniques. Indeed, making the stay in the ICU better while respecting the safety of the patient and the efficiency of the care, could reduce anxiety as well as the appearance of delirium. Studies have been carried out on the effectiveness of music in health care with a positive impact on anxiety and pain. The proposed study aims to evaluate the implementation of relaxation moments adapted to the resuscitation sector from the day after surgery. They target the senses available and accessible at that moment, such as hearing (relaxing music chosen by the patient will be played) and sight (a multi-effect light projector and a bubble column will be deployed). Environmental stressors will be minimized, while maintaining an optimal level of safety. The primary objective is to compare anxiety before and after the first session in cardiac surgery patients in the cardiothoracic and vascular surgery (CCTV) resuscitation unit between the group with the usual rest session and the group with the rest session combining soft music and light. The secondary objectives are based on an evaluation of anxiety over different time periods, patient comfort, occurrence of postoperative delirium, patient pain, average length of stay (LOS). This is a pilot, comparative, monocentric, randomized, interventional research with minimal risks and constraints in 2 parallel groups. 110 patients will be included over a period of 12 months In the experimental group, once a day, a relaxation session with the association of soft music and light will be proposed by adapting the environment of the patient's resuscitation room. The control group will have the usual rest session.

Postoperative delirium (POD) is one of the most frequent complications after surgery in elderly patients, affecting between 20 and 40% of patients older than 60 after major surgery. This complication has huge consequences for the patients, families and society: increase of morbidity and mortality, prolonged length of stay, cognitive and functional decline leading to loss of autonomy, and important additional healthcare costs. Among numerous risk factors identified, perioperative inflammatory stress is a key element in delirium genesis: surgical trauma releases danger signals in systemic circulation, activating immune cells and leading to neuroinflammation. Melatonin is a neurohormone regulating circadian rhythm. But it also exhibits antioxidant and free radical scavenger properties, and regulates energy metabolism and immune function. It has already demonstrated a neuroprotective potential in various animal models. Its use against delirium is promising: it decreases delirium incidence in elderly patients hospitalized in medical ward, and several studies are now recruiting in ICU. The hypothesis of the trial is that in a high-risk population, perioperative melatonin can reduce the incidence of POD. The main objective is to evaluate the effect of perioperative melatonin administration on postoperative delirium incidence in the first 10 days after surgery, in elderly patients (over 70 years old) being hospitalized and scheduled for acute surgery of fractured lower limb (from femoral head to tibial plateau). This is a prospective, national multicentric (24 centers), phase III, superiority, comparative randomized (1:1) double-blinded clinical trial with two parallel arms: Experimental group: melatonin 4mg per os every night, starting the evening before surgery (or 2 hours before emergency surgery) and until day 5 after surgery. Control group: placebo of this drug with the same schedule, during the same period of time. The patients are aged 70 or older, hospitalized and scheduled for surgery of a severe fracture of a lower limb (from femoral head to tibial plateau).

This study aims to compare the effect of dexmedetomidine infusion and oral melatonin on preventing delirium in intensive care unit (ICU) patients.

The aim of this study is to compare the effect of perioperative administration of pregabalin versus dexmedetomidine on the prevalence and lasting duration of delirium in elderly patients after cardiac surgery.

Rationale: Delirium is a type of acute encephalopathy that is triggered by an underlying somatic disorder. Patients experience disturbances in attention, alertness and other cognitive functions. In patients with delirium, a characteristic electroencephalography (EEG) pattern is seen, known as polymorphic delta activity. The MDR certified medical device "Deltascan" can detect this EEG pattern. Traditional clinical delirium screening instruments are known to have limited sensitivity, in particular for detecting hypoactive delirium. We hypothesize that adding EEG based encephalopathy detection to clinical observation scales increases the sensitivity and results in earlier detection of delirium and subsyndromal delirium, resulting in improved clinical outcomes of critically ill patients, such as delirium duration, ICU length of stay or survival. Objective: This randomized controlled trial aims to study the effect of implementation of EEG based encephalopathy detection (DeltaScan, Prolira, Utrecht, The Netherlands, hereafter: DeltaScan) on relevant clinical endpoints (ICU length of stay, sedative requirements and delirium related complications, among others) in a mixed medical and surgical intensive care unit population. Study design: a randomized controlled trial Study population: adult patients (>18 years) admitted to the ICU for unplanned care with a minimal anticipated ICU length of stay of 48h. Intervention: either usual care, where the patients' medical team obtains regular delirium screening, versus usual care plus twice daily DeltaScan measurements. During the daily medical rounds, the DeltaScan results will be presented to the patients' medical team together with decision support, consisting of DeltaScan trend interpretation and protocol-based suggestions for evaluation of underlying delirium cause. Main study parameters/endpoints: primary endpoint will be ICU length of stay. Secondary endpoints are encephalopathy/delirium occurrence, ICU encephalopathy/delirium free days, ventilator free days, organ support free days, sedative, opioid and antipsychotic drug requirement, delirium related complication occurrence, frequency and duration of physical restraints application, ICU mortality, ICU readmission, hospital length of stay, hospital mortality and 90-day mortality. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: In this study, it is not expected that randomization to the intervention group adds risk for patients. This is a study of a diagnostic intervention with additional encephalopathy/delirium observations consisting of a short (90 seconds) EEG measurement, which does not harm the patient. Clinicians will receive protocol-based decision support alongside the diagnostic observation. No additional medical treatments will be conducted as part of the study protocol.

Are psychosocial nursing interventions applied to a patient with cardiac surgery effective in preventing delirium? Are psychosocial nursing interventions applied to a patient with cardiac surgery effective on sleep quality? Are psychosocial nursing interventions applied to a patient with cardiac surgery effective on the level of anxiety?
