Active clinical trials for "Delirium"

Investigators will evaluate the efficacy of postoperative oral suvorexant treatment on nighttime wakefulness after persistent sleep onset (WASO) among adult cardiac surgical patients recovering in the cardiac intensive care unit (ICU). The study include patients ≥ 60 years old undergoing coronary artery bypass graft surgery (CABG), with or without valve surgery (aortic or mitral). Patients will receive either oral suvorexant or placebo for 7 nights starting the night after extubation. The primary hypothesis is that suvorexant compared with placebo decreases WASO, as measured by a specialized electroencephalogram (EEG), the SedLine monitor, during the first night in the cardiac ICU. Investigators will also assess total sleep time (TST), time to sleep onset (TSO), and postoperative delirium and delirium-free days.

The aim of this study is to determine the effect of pregabalin versus dexmedetomidine on the treatment and lasting duration of delirium in fast tracking elderly patients after Coronary Artery Bypass Grafting.

The present clinical trial compares the effect of two general anesthesia (GA) modalities, the one with volatile anesthetic sevoflurane (endotracheal-intubated) and the other integrating total intravenous anesthesia (TIVA) with propofol (non-intubated), on post-procedural delirium and cognitive dysfunction after endovascular thrombectomy (EVT) in the participants with acute ischemic stroke. To assess the outcome of both modalities, the sedation depth of GA will be regulated with processed electroencephalogram monitor to reduce the incidence of postoperative delirium and the peri-procedural blood pressure will be controlled according to the guideline.Based on that, the investigators try to find a better general anesthetic modality for acute ischemic stroke participants undergoing EVT.

Delirium is an important cause of morbimortality in older adults admitted to hospital. Multicomponent interventions targeting delirium risk factors, including physical exercise and mobilization, have been shown to reduce delirium incidence in 30-40% in acute care setting but little is known about its role in the evolution of delirium, once established. This study is a randomized clinical trial conducted in the Acute Geriatric Unit of a tertiary public hospital in Navarra, Spain. Hospitalized delirious patients who meet the inclusion criteria will be randomly assigned to the intervention or control group. The intervention will consist of a multicomponent exercise training programme, which will be composed of supervised progressive resistance and strength exercise training during 4 consecutive days. The objective is to assess the effectiveness of this intervention in reducing the following primary outcomes: duration and severity of delirium, functional status, and length of stay. This study will contribute to determine the usefulness of physical exercise in the management of delirium. It will be the first study to evaluate the impact of a multicomponent intervention based on physical exercise in the evolution of delirium.

Arthroscopic knee surgery is a minimally invasive operation. Postoperative pain usually occurs, especially within 24 hours after surgery, the incidence of pain can be more than 76%. Pain will affect the patient's emotions and life, cause adverse effects, and even lead to postoperative delirium. This study aimed to investigate the clinical effect of ultrasound-guided high fascia iliaca compartment block(H-FICB) in patients undergoing knee arthroscopy and to compare it with the normal method which is femoral nerve block combined with a sciatic nerve block to choose the better way. A double-blind, randomized controlled trial was conducted with 44 patients, aged 18-65 years, ASA I-III, who were scheduled to undergo arthroscopic knee surgery in our hospital were selected, the patients were divided into Group A and Group B by random number table method, with 22 patients in each group. Group A was subjected to the H-FICB under ultrasound guidance before general anesthesia, given 0.375% ropivacaine 30 ml. Group B received ultrasound-guided femoral nerve block combined with sciatic nerve block before general anesthesia, given 0.375% ropivacaine 30 ml. The mini-mental State Examination was used to assess all the patients' primary cognitive status one day before surgery. The initial acting time and the degrees of sensory block and motor block were recorded after the nerve block was completed. Perioperative variables were recorded to be compared. The investigators used the visual analog scale to assess patients' pain degree with postoperative, recorded the occurrence of adverse events such as postoperative nausea and vomiting(PONV), delayed emergence from anesthesia, and respiratory depression. The confusion assessment method was used to assess whether patients experienced delirium.

The goal of this multi-centre phase I/II open-label, single-arm study is to determine the feasibility, optimal dose, and preliminary efficacy of dexmedetomidine to manage agitated delirium among patients near the end of life followed by a palliative care provider in a non-monitored setting. Fifty patients will receive dexmedetomidine (0.2 mcg/kg/hour, titrated up to 0.7 mcg/kg/hour) subcutaneously. Feasibility (recruitment rate, cost), safety (rate of adverse events), dosing, and preliminary efficacy (agitation, delirium severity) will be measured.

The purpose of this study is to determine the feasibility of conducting a randomized controlled trial (RCT) with melatonin for treatment of delirium in critically ill adult patients. From a feasibility perspective, the investigators believe that the proposed design will achieve the minimum enrollment rate necessary to conduct a future RCT on a larger scale.

The purpose of this study is to assess feasibility and potential effectiveness of two different music interventions for managing delirium symptoms in acute geriatric patients.

To observe the effect of intraoperative dexmedetomidine on the incidence of postoperative delirium, postoperative analgesic drug requirements and pain scores in elderly patients undergoing major abdominal surgery.

To determine if daytime bright light will promote circadian alignment and shorten or prevent delirium.
