Active clinical trials for "Emergence Delirium"

It has been shown in previous studies that burst suppression has an effect on the development of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). With the development of technology, EEG-based anesthesia management is getting more and more attention. In particular, methods that reduce anesthetic drug consumption are expected to prevent POD and POCD by reducing burst suppression. There are studies that show that epidural analgesia applications reduce general anesthesia drug consumption in patients receiving general anesthesia. In this study, investigators want to investigate the effect of epidural analgesia combined with general anesthesia on burst suppression. POD and POCD development in these patients will be examined as secondary objectives.

Various pharmacological interventions in peri-operative period have been used in literature to prevent ED which include use of propofol, fentanyl, ketamine, clonidine, midazolam and dexmedetomidine etc (5). Dexmedetomidine is a potent highly selective alpha-2 agonist. Its effect on the receptors in brain results in sedation resembling non-REM sleep with minimal respiratory depression (6). It has been used as continuous infusion or as fixed dose in the range between 0.15 mcg/kg to 2 mcg/kg to prevent ED in children (7, 8, 9). Higher doses result in better prevention of ED at the expense of more hemodynamic disturbances and longer PACU stay (9) while lower doses were not as effective (7). The aim of this study was to investigate the role of fixed dose of 0.2 mcg/kg dexmedetomidine in prevention of emergence delirium in pediatric patients undergoing general anesthesia.

Postoperative delirium (POD) is a common and distressing complication after thoracic surgery. S-ketamine has neuroprotective properties as a dissociative anesthetic. Emerging literature has indicated that S-ketamine can reduce cognitive impairment in depressed patients. However, the role of S-ketamine in preventing postoperative delirium is still unknown. Therefore, this study aims to evaluate the effect of intraoperatively prophylactic S-ketamine compared to dexmedetomidine on the incidence of postoperative delirium in elderly patients undergoing non-cardiac thoracic surgery.

Emergence agitation is a clinical condition in which the child experiences a variety of behavioural disturbances including crying, thrashing, and disorientation during early awakening from anaesthesia. Emergence agitation is a common challenge in children with a reported incidence of approximately 25% ranging from 10 to 80 %. Clonidine is often used off-label in paediatric anaesthesia e.g. sedation in the intensive care unit, prevention of withdrawal symptoms after long-term sedation, as premedication before induction of anaesthesia or as treatment/prevention of emergence agitation. The study is designed as a randomised, placebo-controlled clinical trial evaluating efficacy and safety of a single dose of intraoperative clonidine in children 3-12 months, including pharmacokinetics.

Postoperative delirium is common and associated with significant adverse outcomes. Its etiology is unknown, and little is known about associated risk factors. The investigatorea aim to test whether providing emotional and orientation support can reduce the risk of postoperative delirium in elderly patients undergoing elective non-cardiac surgery. Specifically, the investigators will test whether allowing such patients to keep their hearing and visual aids and be escorted into the operating room by a family member until anesthesia induction reduces the incidence of postoperative delirium. Delirium will be actively screened as part of our institution's clinical practice starting at PACU admission and for a minimum of 2 postoperative days. The investigators will use a multiple cross-over design to enroll all eligible patients and alternate between the intervention and our common practice (removing sensorial aids in the preoperative area and not allowing patients' escort beyond that point) every 2 weeks for up to 2 years.

The purpose of the study is to assess the impact of personalized music on emergence agitation (EA), as measured by Pediatric Anesthesia Emergence Delirium scores in pediatric patients recovering from elective procedures under general anesthesia. Personalized music may help to decrease EA in children undergoing elective surgeries under general anesthesia by decreasing perioperative anxiety and minimizing perceived pain. The study has the potential to improve perioperative care by improving safety, decreasing the need for postoperative pharmacologic and nursing interventions, thereby shortening the time of recovery and improving caregiver satisfaction. Participants participating in this study will be randomly assigned to receive personalized music plus standard of care, or standard of care alone. Those assigned to the music group will receive music in the preoperative holding area as well as in the post-operative care unit.

This is a prospective, randomized, single blinded, controlled clinical trial designed to compare the clinical effects of sedation with dexmedetomidine versus propofol in patients undergoing cardiac surgery.

Anaesthesia-related complications and mortality have been significantly reduced in the last years.(1) Nevertheless, anaesthesia-related side effects, such as post-operative delirium and sleep disturbances should not be underestimated. These side effects are economically challenging because they may lead to prolonged hospital stay and change in lifestyle condition. (2) After general anesthesia' sleep disturbances frequently occur. They are featured by insomnia' hyperinsomnia' narcolepsy' and changed sleep structure. (3.4) There are a lot of risk factors associated with post-operative sleep disturbance such as patient age, preoperative comorbidity, severity of surgical trauma, postoperative pain, postoperative complications and presence of pre-operative fatigue and depression. (5) Insomnia is one of the most prevalent health problems during pre-operative period and after post-operative recovery. It can lead to increase incidence of post-operative complications such as delayed recovery , anxiety and delirium (6). Post-operative delirium is also one of the most common complications following anaesthesia with frequency estimates ranging from 10 to 50%. It is defined as delirium occurring 24 to 72 hours after surgery. (7) There are multiple risk factors for developing postoperative delirium including pre-existing dementia, old age, medical co-morbidities, and psycopathological symptoms. The recognition and treatment of Post-operative delirium is critically important because postoperative delirium is associated with poor outcomes including functional decline, dementia, cognitive impairment, increased hospital length of stay , increased mortality ( 11% increasing in the risk of death at 3 months and up to a 17% increased risk of death at 1 year. (8) Animal studies have found that Magnesium can regulate melatonin production which is a hormone that guide body sleep wake cycle (9) . Magnesium is an essential cofactor for many enzymatic reactions' especially those that are involved in energy metabolism and neurotransmitter synthesis. It is a cofactor involved in more than 300 enzyme systems' regulates diverse biochemical reactions in the body (10.11) . Magnesium supplements were used to improve insomnia symptom among older people in a double blinded placebo controlled clinical trial(12). Low dietary Magnesium intake was found to be significantly associated with depression which is a potential risk factor for insomnia(13). Also using Magnesium sulphate as an adjuvant has been associated with significantly less analgesic requirements and reducing postoperative pain which can improve quality of sleep and decrease insomnia symptoms.(14) AIM OF THE STUDY The aim of this work is to identify the potential predictors of postoperative delirium and insomnia in patients undergoing lumbar fixation under general anesthesia, and to evaluate the effect of intraoperative administration of Magnesium sulphate on the occurrence of post-operative delirium and insomnia in those patients.

This is a clinical trial to evaluate the effect of intravenous iron supplement with Ferinject (Ferric Carboxymaltose) in preventing postoperative delirium after hip fracture surgery.

Postoperative delirium (POD) is a common surgical complication. The incidence is 10% to 22% in neurological procedures, and advanced age is a risk factor for neurological procedures. Many studies have shown that dexmedetomidine(DEX) may reduce the incidence of delirium in non-cardiac surgery patients and elderly patients. However, there are few studies focus on the effect of DEX on POD in elderly patients undergoing neurosurgery. The purpose of this study was to investigate the effect of DEX on POD in in elderly patients undergoing craniotomy.
