Active clinical trials for "Delirium"

The objective of this study is to test the effects of caffeine on neurocognitive and clinical recovery after major surgery. Specifically, this trial tests the primary hypothesis that caffeine will reduce the incidence of postoperative delirium.

Delirium, a form of acute brain dysfunction, occurs in up to 81% of patients receiving mechanical ventilation in the intensive care unit (ICU). Delirium occurring in the ICU is associated with increased functional dependency, cognitive impairment, longer length of hospital stay, and mortality. This study aim to develop a nursing-driven ICU delirium intervention to reduce incidence of delirium, increase the delirium-and coma-free days (DCFDs), and improve ICU patients' function, cognition, and mortality outcomes 3 months following their ICU admission. The "modified Hospital Elder life Program at the ICU (mHELP@ICU)" will be provided to ensure critically ill patients are cognitively engaged, physically active, and nutritionally well-fed. This three-year study is divided into two phases. The first phase aims to ensure the accuracy of delirium assessment using the Intensive Care Delirium Screening Checklist (ICDSC) by ICU nurses of three participating ICUs. The ICDSC records assessed by ICU nurses will be abstracted from medical records and compared with a gold standard ICDSC evaluation by a well-trained, independent assessor. Cohen's kappa will be reported to represent the consistency of the ICDSC assessment between delirium data from medical records and the independent assessor. When the Cohen's kappa is less than 0.8, a 3-month bedside teaching and real-time feedback education program will be implemented at three ICU units to improve the accuracy of ICDSC assessment by ICU nurses. The second phase will be a clinical trial using a stepped-wedge cluster randomized controlled trial design. Adult (18 years and older) critically ill patients receiving mechanical ventilation will be consecutively enrolled from three mix-medical ICUs at a studied medical center. Estimated 266 participants will be cluster-randomized into the intervention and control groups. Participants in the intervention group will receive a 14-day mHELP@ICU, provided by a trained mHELP nurse, while the participants who received the usual care will serve as controls. Effects of mHELP@ICU will be evaluated using the daily delirium and coma data (max 14 days, or until death or ICU discharge) retrieved from the medical records, along with the participants' mortality, cognitive, and functional outcomes, which a blinded outcome assessor will assess at 48 hours, 14 days, 30 days, and 90 days after ICU admission.

The aim of this study is to compare the effect of dexmedetomidine versus ketofol on the incidence of the emergence delirium in children undergoing congenital inguinal hernia repair.

To observe the effect of intraoperative dexmedetomidine on the incidence of postoperative delirium, postoperative analgesic drug requirements and pain scores in elderly patients undergoing robot-assisted pancreaticoduodenectomy.

Post-operative delirium happens when patients wake up from anesthesia. Patients experiencing post-operative delirium are very confused, not being able to think or function "normally". These patients are hard to take care of and they tend to have more dementia as they age compared to patients who don't experience post-operative delirium. Intranasal insulin has been shown to reverse confusion associated with Alzheimer's disease (humans) and AIDS (mice). Intranasal insulin has been safely administered to 1092 patients in 38 different studies. There were no cases of clinically low blood sugar and a few cases of mild nasal irritation that happened also with salt water when the subjects received multiple intranasal doses. No one has tried to reverse post-operative delirium with intranasal insulin. The delirium associated with Alzheimer's Disease and AIDS have very similar symptoms and what happens in the brain is very similar also. The investigators intent is to administer intranasal insulin to patients exhibiting post-operative delirium in order to reverse the symptoms because the investigators think that the three disease states are closely related and intranasal insulin has had some success in reversing the delirium in the other two disease states.

Background and Clinical Need: Delirium is common at the end of life and is challenging to control. There is a clinical need to study the benefits of commonly used drugs like Haloperidol and Olanzapine in the management of hyperactive delirium in advanced cancer or end-stage organ disease patients in a scientifically robust manner. Aims/Hypotheses: The investigators aim to study the effectiveness of Haloperidol compared with Olanzapine in the management of hyperactive delirium in advanced cancer or end-stage organ disease patients receiving palliative care. The investigators hypothesise that Olanzapine is as effective as Haloperidol in the control of hyperactive delirium. Methods: The investigators will conduct a pragmatic, multi-centre, (hospital, inpatient hospice, community hospital) open-label randomised-controlled trial comparing the use of Haloperidol versus Olanzapine in advanced cancer or end-stage organ disease patients with hyperactive delirium. The primary outcome is the change in Richmond Agitation and Sedation Scale (RASS) scores among patients in each treatment group at 8 hours post-drug administration. The secondary outcome is the control of hyperactive delirium at 24, 48 and 72 hours using either Haloperidol or Olanzapine. The mean doses of Haloperidol and Olanzapine used as well as the volume of rescue Midazolam required as well as side-effects of the study medications, survival after enrolment into study will also be studied. Significance to palliative care The results of this study will advance the knowledge of delirium management worldwide with regards to the efficacy of Haloperidol and Olanzapine in managing hyperactive delirium in patients with advanced cancer or end-stage organ disease. Haloperidol is used traditionally in palliative care for managing delirium. However, as a conventional anti-psychotic, it does cause extra-pyramidal side-effects. Olanzapine, a newer atypical anti-psychotic with a more favourable side-effect profile is being used increasingly in the control of delirium. These 2 commonly used drugs have never been compared head to head in a randomised-controlled, multi-centre study.

As patients with terminal illness enter the dying phase, they may experience symptoms of restlessness, agitation, or cognitive disturbance, known as terminal delirium. In community care, pharmacological therapies are utilized to manage the syndrome, the most commonly used being neuroleptics haloperidol and olanzapine. However, there is currently a dearth of studies on the efficacy and safety between haloperidol and olanzapine in the community palliative care setting; existing studies involve non-terminal patients in the hospital suffering from acute delirium. To fill this gap, an open-label randomized clinical trial is proposed to compare the effects of haloperidol and olanzapine in the management of terminal delirium in home hospice patients who are imminently dying. Key outcome measures are the reduction of delirium symptoms and the reduction of agitation. Secondary outcome is comparing the adverse effect burden on patients.

Delirium is a neurobehavioural syndrome that frequently develops in the postoperative and/or ICU setting. The incidence of elderly patients who develop delirium during hospital stay ranges from 11-82%. Delirium was first described more than half a century ago in the cardiac surgery population, where it was already discovered as a state that might be accompanied by serious complications such as prolonged ICU and hospital stay, reduced quality of life and increased mortality. Furthermore, the duration of delirium is associated with worse long-term cognitive function in the general ICU population. This long-term experience with delirium suggests a high socioeconomic liability and has been a focus of many studies. The aforementioned consequences of delirium are observed in all of three subtypes: hypoactive, hyperactive, and mixed. Pharmacological treatment options for hypoactive delirium are lacking. Since patients in hypoactive delirium suffer from disturbed circadian rhythm, the investigators suggest that the administration of melatonin as a promising possibility in these patients to shorten delirium duration and to lower its severity. Previous investigations confirmed loss of melatonin rhythm in patients that had developed delirium thus reasoning the study hypothesis. In this randomized study, the investigators aim to test the hypothesis that the reinstitution of a normal circadian rhythm by the administration of melatonin compared to placebo after diagnosis of hypoactive delirium, decreases the duration of delirium and reduces the transmission to a form of agitated delirium. The administration might have to be repeated several times to achieve resolution of delirium.

Delirium is a frequent and serious problem in hospitalized patients; it is associated with multiple hospital-acquired complications. There is evidence that the incidence of deliri-um may be minimized by multimodal interventions (pain management, shortening the duration of mechanical ventilation, light sedation, avoiding benzodiazepines, routine delirium monitoring, and early mobilization). Even though a clear association between sleep and delirium has not been established, many studies suggest that sleep disturban-ces may be a key risk factor for the development of delirium. Therefore, sleep promoti-on is becoming an integral part of clinical care. The project support the hypothesis that non-pharmacological preventive interventions promoting sleep (sleep protocol) positive-ly influence the quality of sleep and reduce the incidence of delirium in hospitalized patients. This will be verified by qualitative and quantitative research methods, with the quantitative study being divided into three prospective cross-sectional studies and one interventional study. Data will be obtained from 3240 hospitalized patients by combi-ning subjective methods (questionnaire surveys) and objective measurements (acti-graphy). The project outcomes will allow better understanding of the relationship betwe-en sleep and delirium. A set of non-pharmacological preventive interventions promoting sleep will be developed, with a subsidiary aim to potentially reduce the incidence of delirium in hospitalized patients.

Early mobilization is recommended because it is effective in improving symptoms for patients after cardiac surgery. However, the optimal timing of mobilization for postoperative patients is not unclear. How early is early? As early mobilization in the ICU is safe and may reduce healthcare costs, the goal was to assess the effect of early mobilization in the ICU on the incidence and duration of delirium.
