Filter by:Postoperative agitation and emergence delirium describe a spectrum of symptoms of early postoperative negative behavior, in which the child experiences a variety of behavioral disturbances including crying, thrashing, and disorientation during early awakening from anaesthesia. The symptoms are common with a reported incidence of approximately 25%. Some clinical trials have studied the effect of prophylactic oral melatonin for reducing the risk of emergence agitation in children, some finding a considerable dose-response effect. Melatonin has a low bio-availability of approximately 15 %. The safety of exogenous melatonin for pediatric patients has been studied with no apparent serious adverse effects, even at repeated short-term use of high doses of intravenous melatonin. The aim of this clinical trial is to investigate the prophylactic effects and safety of intravenous melatonin administered intraoperatively for prevention of postopreative agitation and emergence delirium in children after an elective surgical procedure. The study is designed as a randomised, double-blind, placebo-controlled clinical trial.
This study is designed to test the hypothesis that, for older orthopedic patients who developed postoperative delirium, combining buccal acupuncture with routine care will shorten delirium duration and relieve delirium severity.
1. To evaluate the effectiveness and safety of acupuncture on POD in diabetic patients undergoing surgery, to provide effective prevention and treatment measures of integrated traditional Chinese and western medicine for reducing the incidence of postoperative delirium in high-risk groups, and to provide clinical basis for further promotion of integrated traditional Chinese and western medicine anesthesia in the future. 2. To investigate the relationship between POD and rSO2 in diabetic patients undergoing surgery. To clarify the predictive value of intraoperative rSO2 monitoring on postoperative cognitive function in patients with diabetes, and to explore the effect of acupuncture on cerebral blood flow perfusion in patients with diabetes.
Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) occur in 11-51% of patients after surgery, and its prevalence increases with age. The occurrence of delirium is associated with increased morbidity and mortality, prolonged hospital stay, worse functional recovery. Orthopedic procedures and specifically joint replacements have been considered as a major risk for development of chronic postsurgical pain (CPSP). Approximately 13-44% of patients will develop CPSP after knee or hip arthOpioid abuseroplasty. CPSP may cause the discomfort, distress, disability and opioid abuse. Mounting evidence has revealed that inflammation triggered by surgical trauma plays a key role in POD, POCD and CPSP. Recent studies found that vagus nerve stimulation showed the suppression of inflammation. In this study, the effect of perioperative transauricular vagus nerve stimulation on the prognosis of patients undergoing arthroplasty will be investigated, providing potential solutions for the prevention and treatment of postoperative cognitive dysfunction, postoperative delirium and chronic postsurgical pain.
Postoperative delirium (POD) is one of the most frequent neurological complications in elderly patients and is closely associated with longer ICU stay and hospitalization, deterioration of long-term neurocognitive function, and increased mortality. The incidence of POD is significantly higher in elderly patients undergoing cardiac surgery than in other populations. Therefore, the prevention of POD is an important clinical problem to be solved urgently. In this study, we intend to observe the effect of RIPC on the prevention and treatment of POD in patients undergoing cardiac surgery through a prospective randomized controlled trial.
Perioperative neurocognitive impairment, including postoperative delirium (POD), is common in older patients after anesthesia and surgery and is associated with poorer short- and long-term outcomes, including worsening cognitive decline, surgical Complications, increased risk of hospitalization, and death after cardiac and noncardiac surgery. POD is more common with age, occurs in up to 65% of elderly patients, and increases in patients with mild cognitive impairment. As more and more older adults undergo surgery and anesthesia, POD has become a major global health challenge requiring urgent attention. Prevention strategies involving multidisciplinary perioperative interventions may have some benefit overall, but the impact on POD remains uncertain. Known inflammatory responses may be associated with adverse outcomes such as neurocognitive dysfunction and cancer recurrence after major surgery. Different anesthesia methods, the regulation of anesthesia drugs on postoperative inflammatory response has been confirmed in vitro, but its clinical significance is still unclear. Therefore, exploring the risk factors of inducing POD has important clinical significance for the early prevention of POD. Second, a recent study found that the incidence of POD was significantly higher in patients whose sleep cycle was disturbed during hospitalization. Animal experiments found that after 5 hours of sleep deprivation in adult mice, the number of dendritic spines in CA1 neurons in the hippocampus was reduced, and the length of dendrites was significantly shortened, which damaged the synaptic transmission of the central nervous system, and significantly improved memory and cognitive function. Damaged. And many studies have investigated whether bispectral index (BIS)-guided anesthesia is associated with a reduced risk of POD, compared with "standard-of-care" anesthesia or the use of goal-directed end-tidal volatile agent concentrations, the reasoning is that the use of BIS-guided anesthesia results in less anesthesia exposure, and therefore "light" anesthesia may reduce the incidence of postoperative POD compared to "deep" anesthesia. However, this conclusion is still controversial. The study of Anshentong et al. has confirmed that deep anesthesia with BIS maintained at 40-49 can delay postoperative recovery time, reduce the level of inflammatory factors and the incidence of early postoperative cognitive impairment, and reduce the incidence of early postoperative cognitive impairment. Brain damage. Therefore, although age is known to be the main correlative factor for POD, different depths of anesthesia may cause different stress responses in patients, resulting in different release of inflammatory factors. An additional risk factor may be preoperative psychiatric symptoms, and assessment of mental status is often overshadowed by concerns about multiple comorbidities in older adults. Anxiety disorders are one of the prominent psychiatric symptoms in older adults. very common. Preoperative anxiety is defined as an unpleasant restless or tense state secondary to patient concerns about illness, hospitalization, anesthesia, surgery, or the unknown. Studies on the relationship between preoperative anxiety and POD also vary in consistency due to the characteristics of different populations. Many of the current studies are mostly single-center with limited sample size, which may have a certain bias in the conclusions. Therefore, the investigators designed and planned to conduct a multi-center, large-sample cohort study to determine the impact of perioperative related factors and inflammatory markers on elderly patients undergoing non-cardiac major surgery .
Delirium is a common symptom in the intensive care unit, which greatly affects the prognosis of critically ill patients and increases medical costs. Although many studies have implemented preventive measures, they have not been able to significantly improve the prevalence of delirium, because many medical measures devises in the intensive care unit are still necessary for patients. Therefore, early detection of patients with delirium symptoms, risk factors, and immediate Delirium management is important. Nurses are the first line of clinically important roles in assessing delirium symptoms. So, design a delirium simulation education for nurses is important.
To determine whether continuous theta burst stimulation can cure postoperative delirium in senior patients.
Postoperative delirium (POD) is a common complication, and the incidence of POD after deep brain stimulation(DBS) implementation ranges from 10% to 40%. Previous studies suggested that aging and existing non-motor symptom were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing DBS 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 on POD for patients undergoing DBS was seldom reported. The purpose of this study was to investigate the effect of dexmedetomidine on POD in patients with Parkinson' Disease undergoing DBS.
Surgery or trauma may cause serious problem to patients, especially for senile ones, like postoperative delirium or more postoperative complications. Here, we conduct a investigation of SFI for preventing the happening of POD or postoperative complications.
