Active clinical trials for "Delirium"

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.

Cognitive complications, that is problems with thinking and memory, are incredibly common after surgery, occurring in 10-50% of all older surgical patients. These complications can take different forms, but one of the most common is postoperative delirium (POD), a short-term state of confusion. In addition to being stressful for patients and their families, POD is linked to longer hospital stays, increased costs, higher mortality rates and other problems after surgery. Despite this, POD is often not recognized by doctors and there are currently no effective medications to treat POD. However, simple strategies such as helping patients to sleep properly and remain hydrated, have been shown to help. This study is testing if a delirium-reduction program will reduce postoperative delirium (POD) in older surgical patients. The investigators will first test memory and thought processes before surgery to find people who are most likely to develop POD. Once these people have been identified, they will be enrolled in a program which includes recommendations for their care team (e.g. surgeon, anesthesiologist, nurses) as well as educational materials for them and their family related to things that can be done to prevent delirium. By identifying at-risk patients and making sure that their doctors and caregivers are aware of how to prevent delirium, the investigators expect that this study will make surgery safer for older surgical patients.

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.

Delirium is an acute cerebral dysfunction syndrome characterized by acute fluctuating changes in consciousness, cognitive dysfunction, and disorientation. It's especially common in critically ill patients of emergency intensive care units and seriously threatens the survival and prognosis of patients and causes heavy economic burdens to the family, society, and medical service system. Impaired verbal communication, unfamiliar medical personnel, physical restraint, spatial-temporal disorientation, mechanical ventilation and sedation medication use can lead to a lack of adequate sensory stimulation and a high risk of delirium. Acoustic stimulation as a non-invasive non-pharmacological intervention can provide some sensory stimulation as a surrogate for critically ill patients. This research designs the content scripts from the needs of ICU patients and families for sound stimulation. The goal of this randomized controlled study is to test the effect of auditory stimulation by family voices in preventing delirium among sedative patients in emergency Intensive care units.

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.

The primary aim of this interventional study is to investigate the impact of perioperative administration of Maxigesic (combination of acetaminophen and ibuprofen) on delirium after minimally invasive lung surgery in elderly patients. The Maxigesic group receives a total of 5 doses of Maxigesic (20mg/kg, maximum dose per serving: 1g) every 6 h from immediately after anesthesia induction. The control group receives the same volume of normal saline. Researchers compare the incidence and severity of postoperative delirium for 5 days after surgery.

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.

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.

Prophylactic TxA administration in patients undergoing major gastrointestinal surgery reduces the incidence of delirium after surgery when compared with placebo. The unifying hypothesis is that systemic and neuro-inflammation lead to neuronal injury and resultant postoperative delirium.

Postoperative delirium (POD) is a common complication, and the incidence of POD ranges from 10% to 60%. Previous studies suggested that frontal approach and tumor located at the temporal lobe were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing awake craniotomies are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine (DEX) on POD for patients undergoing awake craniotomies remains unclear. The purpose of this study was to investigate the effect of DEX on POD in patients undergoing awake craniotomies.
