Active clinical trials for "Delirium"

Preoperative anxiety is associated with adverse consequences such as emergence delirium, and postoperative behavioral changes. According to previous studies, providing information of anesthetic procedures helps to lessen preoperative anxiety. However, verbal explanation alone provides the limited effect, and the tour program of the operating room prior to surgery may not be possible for a number of hospitals due to organizational and financial reasons. Therefore, the virtual reality (VR) tour of the operating room may be an innovative and novel method to give children information about the preoperative process and to alleviate the preoperative anxiety. In this study, we intend to evaluate the effects of the operating room virtual tour on preoperative anxiety as well as emergence delirium and postoperative behavioral changes, in pediatric patients.

The Study is a double-blinded, randomized, placebo-controlled trials. The Objective is to investigate the effect of single-high-dose glucocorticoid on surgical stress response and postoperative delirium among Elderly hip Fracture Patients undergoing surgery.

The purpose of this study is evaluate postoperative delirium after general anesthesia and regional anesthesia in elderly patients undergoing hip fracture surgery. Our research hypotheses are: (1) regional anesthesia may contribute to decrease the incidence of postoperative delirium. (2) Regional anesthesia may improve the outcome of elderly patient and reduce healthcare costs associated with postoperative delirium. (3) Postoperative delirium may result in poor long-term functional outcomes.

The purpose of this study is to investigate the effectiveness of a preventative low-dose of Haloperidol to prevent delirium in patients undergoing a esophagectomy, pneumonectomy or thoracotomy. Delirium is state of severe confusion and some symptoms include: Cannot think clearly Have trouble paying attention Have a hard time understanding what is going on around them May see or hear things that are not there. These things seem very real to them.

Many individuals experience an acute change in thinking and reasoning skills after surgery. This is called post-operative delirium (PD). PD symptoms typically start 1-3 days after surgery. Advanced age has been identified as a risk factor for PD. The purpose of this study is to determine if performing mental exercise, before surgery, will help reduce post-surgery memory and thinking problems. Assuming a 30% incidence of PD and proposed 50% reduction of PD in the intervention group (15% incidence), a total of 242 patients (1:1 ratio, 121 in each group) will achieve 80% power to detect 50% reduction using chi-square test at a 5% type I error rate. Assuming approximately 1/3 of consented patients either fail screening or do not complete the study after consent, we expect to consent 358 patients. At least 8 days before surgery, subjects complete a series of questionnaires to assess baseline cognition level (or thinking ability) and status of overall well-being. At the completion of the screening visit, qualifying subjects are randomized into two groups: Participants randomized into the Cognitive Exercise group are expected to complete tablet-based brain games provided by Lumosity. These subjects are given a handheld tablet for the duration of the preoperative period. Participants in this group are expected to complete a minimum of 10 hours within at least 8 days prior to surgery. Participants randomized into the Normal Activity group are encouraged to carry out their baseline daily activities, and do not have any study-related cognitive exercise expectations before surgery. These subjects still complete the same questionnaires and assessments as the Cognitive Exercise group throughout the study, however, are asked not to alter their normal daily routine of mental exertion (i.e. watching television, reading, puzzles, etc.) and are not permitted to subscribe to Lumosity while in the research study. On the day of surgery, a baseline delirium evaluation (CAM - Confusion Assessment Method) is taken before surgery. During surgery, research personnel monitor vital signs and medications given. After surgery, another CAM evaluation is taken in the post-operative recovery room. Throughout the subject's hospital stay, pain levels and medication usage are recorded. The CAM and MDAS (Memorial Delirium Assessment Scale) are used to identify and determine severity of PD. The evaluations are given twice daily, at at 7:30AM ± 1.5 hrs and 6:30PM ± 1.5 hrs, for 7 days or until hospital discharge (whichever comes first). The Postoperative Quality of Recovery Scale (PQRS) is used each post-operative day at 6:30PM ± 1.5 hrs until discharge, and completed over the phone on POD 7 if patient discharged. The PQRS is also administered over the phone on POD 30 and POD 90.

Postoperative delirium (POD) is a frequently occurring complication after cardiac surgery. Its occurrence is associated with worse outcomes of patients, including increased morbidity, prolonged hospital stay, increased medical cost, and higher mortality. It is also associated with long-term cognitive decline and decreased quality of life. However, until recently, pharmacological interventions that can effectively prevent its occurrence are still limited. The purpose of this study is to investigate whether perioperative dexmedetomidine use can decrease the incidence of postoperative delirium in patients undergoing cardiac surgery.

The overall goals for this study are: 1) to develop a predictive model to identify patients who are stable enough to forego vital sign checks overnight, 2) incorporate this predictive model into the hospital electronic health record so physicians can view its output and use it to guide their decision-making around ordering reduced vital sign checks for select patients.

Delirium is highly associated with adverse clinical outcomes of intensive care unit (ICU) patients, including increased cognitive impairment, duration of intubation, ICU length of stay, mortality, physical dependence, and health care costs. This randomised controlled study will firstly develop a family-supported sensory stimulation package based on the literature review as well as the findings of the cross-sectional survey and the in-depth interview. The intervention effects than will be evaluated using outcomes including delirium incidence, delirium duration, delirium severity, ICU patients' consciousness and cognitive function as well as family members' satisfaction and anxiety. This study is expected to provide evidence of the effectiveness of family-supported sensory stimulation on preventing delirium among ICU patients.

Flumazenil rapidly antagonizes benzodiazepines (BZDs); it may induce agitation, seizure, or delirium, especially when applied to patients who have taken BZDs for a long time. On the contrary, it may help patients regain consciousness in a stable and calm state by appropriately reversing the central nervous system depressant effects of BZDs. In this study, we aim to investigate the impact of flumazenil on the emergence delirium in patients anesthetized with remimazolam, the short-acting BZD drug.

The purpose of this randomized clinical trial is to determine whether risperidone alone, trazodone alone, or a combination of risperidone and trazodone is superior for the treatment of ICU acquired delirium. The hypothesis is that combination therapy is superior to either agent alone in treating ICU acquired delirium and sustaining delirium free time.
