Filter by: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 .
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.
The aim of this study is to evaluate how C-reactive protein (CRP) and homocysteine and their interaction contribute to postoperative delirium, based on our previous finding on the interactions of CRP, homocysteine and postoperative delirium.
An assessment of the feasibility of structural and functional magnetic resonance imaging (MRI) brain scans in older people who have recovered from and older people who never had delirium after hip fracture surgery
The purpose of this study is the efficiency of es-ketamine on postoperative delirium among old patients with elective lobectomy
The relationship between zonulin and interleukin-8 levels and postoperative delirium development in patients who had femur fracture surgery under regional anesthesia
To investigate the impact of cTBS on the incidence of postoperative delirium and changes of cognitive function in elderly patients after surgery. To explore whether short-term cTBS can reduce the risk of postoperative delirium as a preventive strategy.
The investigators intend to recruit 600 participants to see if alpha power during anesthesia is influenced by analgesic medication and associated with a reduction of delirium following surgery.
