Filter by:the hypothesis is that Dexmedetomidine seems to decrease incidence of post-operative delirium . one possible mechanism is that Dex have a minor influence on cognition, since it has no effect on GABA receptor，another is that Dex could induce a sleep similar to natural sleep, thereby decreasing sleep deprivation and circadian rhythm disorder in post-operative patients. In this study , investigators devise the two different sedatives(Dexmedetomidine and Propofol)'influence on postoperative delirium in hip fracture elderly participants under spinal anesthesia
To investigate whether the composition of the gut microbiota is different in patients that develop delirium during critical illness as compared to patients who do not.
Decline in cognitive function after surgery occurs most commonly in older patients and patients undergoing major surgeries, such as heart surgery. Postoperative Cognitive Dysfunction (POCD) may last a prolonged period of time while Postoperative Delirium (POD) is a more acute disturbance in attention, awareness and cognition. The cause of POCD and POD are not fully understood, however some of the pathophysiology of POCD is similar to that of Alzheimer's disease (AD). Insulin given intravenously during heart surgery has been shown to preserve short and long-term memory function after the operation. Clinical trials further demonstrated that insulin given via the nose (intranasal) improves memory performance of patients with AD or cognitive impairment suggests that intranasal insulin also could be a therapeutic option for POCD and POD. This study is designed to examine the effect intranasal insulin on POCD and POD. The goal is to investigate whether administration of intranasal insulin during and after heart surgery improves cognitive function postoperatively.
This study investigates electrical acupoint stimulation (EAS) administered in peri-operation for improving postoperative recovery in elder patients, who accept knee arthroplasty. the surgery cause to change of stress response, which might be associated with postoperative recovery of patient Totally, three groups are created, 1/3 participants receive transcutaneous electrical acupoint stimulation, 1/3 participants receive electroacupuncture, the rest 1/3 will use sham transcutaneous electrical acupoint stimulation.
To investigate whether limb remote ischemic preconditioning (LRIP) could safely decrease the incidence of delirium in elderly patients after non-cardiac surgery.
The researchers are conducting a research study to see whether listening to music during an operation will have a positive effect on the way that children wake up from surgery/anaesthetic. It is a common phenomenon where children wake up unhappy, irritated and screaming (known as emergence delirium). Research have shown that music decreases anxiety and pain. The researchers want to see whether music can also influence a child's behaviour after emerging from anaesthesia. In other words whether they will be more calm and cooperative after listening to music while they are asleep during surgery. Should music have a positive effect, anaesthesiologists may use it in future to improve care of patients coming for surgery.
Hip fractures are common, costly and affect older people - Canadians spend 1 billion dollars to treat hip fractures each year. Unfortunately, as many as two-thirds of hip fracture cases suffer a complication known as delirium, or acute confusion. Patients with delirium may become frightened and agitated. This in turn leads to other serious problems. Having delirium doubles the chances of dying or can increase the need for admission into a nursing home. People with delirium spend an extra week in hospital on average. Using ultrasound to locate and 'freeze' or block specific nerves can stop hip fracture pain almost immediately, and use of this technique is known to reduce delirium when administered by Anaesthetists to patients at the time of their hip operation. Unfortunately, patients with hip fractures commonly wait hours or even days in the Emergency Department (ED) prior to their operation. Currently, these patients are given narcotic pain killers like morphine to dull their pain, as most ED physicians have not been trained in using this 'freezing' technique and Anaesthetists are rarely able to leave the operating room to administer freezing to patient in the ED. The EDU-RAPID study will test whether training ED physicians on how to use the nerve freezing technique will reduce the number of patients who develop delirium after a hip fracture. To study this, ED physicians will be trained at 6 hospitals in small groups every 6 weeks over 18 months. The study will look at how patients who are treated by ED physician who has been trained compare to patients treated by a ED physician who has not yet been trained. Also, the study will see if the training motivates ED physicians to use the block regularly. If correct, this study could significantly improve the comfort, quality of life, and independence of patients who suffer a hip fracture. In addition, if the study shows a reduction in delirium rates, this could represent a significant cost reduction to the health care system.
Acute confusional states known as delirium frequently occur in Intensive Care Units (ICU), mostly after cardiac surgery, leading to serious consequences. Sleep deprivation has been described in ICU patients and is considered as a risk factor for delirium but its role is still unknown. It is therefore essential to identify whether sleep deprivation and more specifically REM sleep alterations could facilitate occurence of delirium in ICU.
For patients requiring the heart valve replacement surgery, heart function is injured in different degree.Thus, minimizing the impact of the anesthesia drug on the cardiovascular system has important clinical meanings. Etomidate has slight effect on the cardiovascular system, often used in the induction of anesthesia, however target controlled infusion etomidate in maintenance of anesthesia is less used. So, the trial is designed to observe the application value of TCI etomidate in thoracoscopic mitral valve replacement surgery.
The purpose of this study is to evaluate the efficacy of low dose quetiapine for the prophylaxis of delirium in critically ill patients in medical intensive care unit.
