Active clinical trials for "Delirium"

Emergence delirium/emergence agitation (ED/EA) is a behavioral phenomenon of unclear etiology consisting of short lived behavioral changes that can be both traumatic to families and pose a safety risk to patients and staff. ED is characterized by a variety of presentations, including crying, excitation and agitation, that occur during the early stage of recovery from general anesthesia, generally in the first 30 minutes. Emergence delirium occurs in children of all ages following an anesthetic with halogenated agents (e.g. sevoflurane/isoflurane) with or without having undergone a surgical procedure (e.g. MRI patients). Presently, the treatment for ED is to revert the patient back to a hypnotic state mainly with sedatives so that they may "reset" themselves postulating that by re-inducing a hypnotic state, the brain has time to resolve this issue. The hypothesis of this study is that during ED, there is failure of organized EEG activity, especially alpha wave activity and that by enhancing alpha activity, the incidence of ED may be reduced without the need for additional pharmaceuticals which may be costly, delay recovery and are not without adverse effects specifically cardiopulmonary depression through the use of blue monochromatic light.

Objective: To evaluate the effect of care bundle on prevention of delirium among elderly patients with hip fractures. Methods: A prospective randomized case control study was performed for 80 patients (≥65 years) with hip fractures treated surgically according to their ages and the type of fractures from March 1th of 2017 to June 30th of 2017．There were 11 males and 69 females, with the age of (79.3±7.84) years. Confusion assessment method (CAM) was applied to diagnose delirium after surgery, the subjects were randomized divided into experimental group (n=43) and control group (n=37). The parameters next were recorded and analyzed, including age, gender, type of fractures, type of internal instrument, amount of bleeding, time between injured to surgery, time length of operation, type of operation, VAS, incidence of delirium, perioperative complications and adverse events.

Will the use of prophylactic Haloperidol for patients undergoing open heart surgery reduce the incidence, duration, and severity of post cardiotomy delirium?

The investigators propose a multicenter, randomized, double-blinded, placebo-controlled trial to study the effect of additive low-dose haloperidol prophylaxis on top of exciting care in a general population of older patients (age 70 years and over) acutely admitted to the hospital through the emergency department (ED) for general medicine and surgical specialties, and who are at-risk for developing in-hospital delirium on admission according to the VMS delirium risk questions (one or more positive answers out of three questions). The investigators hypothesize that this intervention will reduce the incidence of in-hospital delirium as well as duration and severity of delirium.

The aim of this study is to determine the effects of a low dosage of prophylactic haloperidol in patients with a high risk to develop delirium, defined by an expected ICU length of stay of >1 day. The investigators hypothesized that haloperidol prophylaxis in patients with a high risk for delirium reduces 28-day mortality, delirium and delirium related outcome. Two different dosages of haloperidol are used in this study to compare with placebo. A dosage of 1mg, or 2mg or placebo three times a day in a double-blinded fashion resulting in a three-armed multicentre randomized double-blinded placebo-controlled trial. To relate the potential beneficial effects of haloperidol to the a priori risk to develop delirium, the PREDELIRIC-model (delirium prediction model for ICU patients) will be used. This will enable the investigators to determine the preventive efficacy of haloperidol in patient groups based on their risk to develop delirium.

This research is being done to see what effects sedative drugs during surgery have on peoples' thinking processes after they wake up.

Postoperative delirium is an acute mental syndrome that is caused by diffuse cerebral dysfunction resulting from the action of predisposing and precipitating factors acting together. It is associated with an increase in mortality and postoperative morbidity and prolongs the period of hospitalization of the patient Videolaparoscopic surgery has been increasingly used as a therapeutic and diagnostic method. In order to have a good visualization of the anatomical structures on which it will act, it is necessary to introduce gas into the cavity, a mandatory component known as pneumoperitoneum. This technique gives special characteristics for the conduction of anesthesia, since the positive intra-abdominal pressure results in changes in the patient's physiology. Some types of laparoscopic surgery require the position of Trendelenburg for better visualization of the operative field. Among the changes related to this position are the increase in cardiac output and intracranial pressure. In order to optimize the anesthetic procedure, anesthetic blocks have been increasingly used, especially the spinal. The association of general anesthesia with spinal anesthesia, followed by its contraindications is advantageous, because lower doses of anesthetic agents are necessary for the maintenance of general anesthesia. This association results in an earlier awakening, a reduction of nausea / vomiting, postoperative pain, length of hospital stay, cost effectiveness and greater patient satisfaction. As a disadvantage, by associating general anesthesia with spinal anesthesia, patients become susceptible to the adverse events of spinal anesthesia. Among these, the most common are headache, hypotension, nausea and vomiting, pruritus, urinary retention and tremor. Performing spinal anesthesia with opioids alone, without the use of local anesthetic is also possible, with morphine being the most used. The benefit of this variation of technique is analgesia for a period of 12 to 24 hours, without the cardiovascular consequences resulting from the action of the local anesthetic. JUSTIFICATION: There are no studies in the literature evaluating The objective of this study is to analyze if the anesthetic techniques employed, general anesthesia or general anesthesia associated with subarachnoid block, for videolaparoscopic oncologic surgeries, in Trendelenburg position, differ in relation to the incidence of delirium in the postoperative period.

This research study will evaluate the effectiveness and estimate the feasibility of administering an investigational drug called 'CN-105' (the study drug), to prevent postoperative cognitive decline, delirium (serious confusion) and underlying brain inflammatory and brain activity changes in adults 60 years and older undergoing surgery.

The prospective, randomized controlled experimental trial investigates the effectiveness of delirium preventive care protocol for hip fracture patients.

This study is a double-blind clinical trial, in pediatric patients aged 1-12 years with physical status ASA (American Society of Anesthesiology) 1 and 2 who underwent eye surgery under general anesthesia using Sevoflurane inhalation agents, in investigator institution during February-May 2019.. There were 64 children obtained by consecutive sampling, who underwent eye surgery in investigator institution during February-May 2019. The subjects then grouped into dexmedetomidine group and midazolam group. Effectiveness was assessed from Emergence Delirium (ED) events, recovery time, and post-premedication desaturation events. Data analysis using Chi Square test and Mann-Whitney test.
