Filter by:Patients undergoing cardiac surgery were recruited. Baseline characteristics of all subjects were collected. The 3-minute Delirium diagnostic Scale (3D-CAM) was used to screen the POD group and non-POD group from the recruited subjects during the first 7 days after surgery. Peripheral blood samples were collected 1 day before surgery and 2 day after surgery. . Plasma was isolated from peripheral blood for subsequent proteomic analysis.
The observational study aims to discover differentially expressed circRNAs in the peripheral blood of patients with postoperative delirium, which aims to answer the main questions at: Whether there are changes in circRNA expression in peripheral blood in elderly patients with delirium after cardiopulmonary bypass surgery? Whether the circRNA with altered expression plays an important role in the occurrence and development of POD? What are the functions and underlying mechanisms of circRNA with altered expression in POD? Voluntary patients will receive follow-up 1 day before and 7 days after surgery to assess their cognitive function, and peripheral blood will be collected 1 day before and 3 days after surgery. The study divided patients into POD group and non-POD group according to whether delirium occurred within 7 days after surgery.
This research study will evaluate the effectiveness of postoperative administration of a drug called suvorexant, to improve postoperative sleep and decrease the severity of delirium (serious confusion) in adults 65 years and older undergoing non-cardiac surgery.
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.
The purpose of this study is to determine the feasibility of conducting a randomized controlled trial (RCT) with melatonin for treatment of delirium in critically ill adult patients. From a feasibility perspective, the investigators believe that the proposed design will achieve the minimum enrollment rate necessary to conduct a future RCT on a larger scale.
Postoperative delirium is a geriatric syndrome occurring after anesthesia and surgery which manifests as acute alterations in mental status, involving changes in cognition, attention, and levels of consciousness that tend to fluctuate The use of dexmedetomidine with the intention to prevent postoperative delirium remains controversial. Where it has shown to be effective in older adult patients undergoing cardiovascular and non-cardiovascular surgeries
In view of the increasingly severe aging situation in China, the perioperative brain health of elderly patients has received increasing attention. Postoperative delirium (POD) is a common postoperative complication characterized by acute consciousness and cognitive dysfunction. The incidence of POD in elderly patients undergoing elective non cardiac surgery is 20%~45%, which often indicates poor cognitive recovery and becomes a heavy burden for family and society. Although the weight of human brain only accounts for 2% of body weight, the oxygen consumption accounts for 20% of the total oxygen consumption of the whole body. On July 2, 2022, the British Journal of Anaesthesia (Chinese Academy of Sciences Division 1, Anesthesiology Division 1, IF11.719), the top international Journal in the field of anesthesiology, published the scientific research achievements of the first author of the applicant. It was found for the first time that sevoflurane, the most commonly used inhalation anesthetic in clinical practice, can cause the activation of glycolysis and the increase of lactic acid in the brain of elderly non-human primate marmosets, which suggests that general anesthetics will affect brain metabolism in the perioperative period. Therefore, we hypothesized that perioperative changes in brain metabolism might be related to the occurrence of POD in elderly patients. The purpose of this study was to study the relationship between the changes of brain metabolites and POD during perioperative period by noninvasive monitoring of the characteristics of brain tissue metabolites 24 hours before and 24 hours after the operation with hydrogen ion proton magnetic resonance spectroscopy (1-HMRS). In order to complete this purpose, this study plans to collect subjects aged 65~90 years who are scheduled to undergo oral and maxillofacial surgery under general anesthesia. The changes of brain metabolites before and after operation were collected by 1-HMRS, and the postoperative delirium related scale was evaluated to analyze the relationship between perioperative changes of brain metabolites and POD.
In population of intensive care unit (ICU), most studies compared atypical antipsychotics such as quetiapine with the traditional haloperidol in delirious patients of various forms and etiologies. The role of such agents in patients with hyperactive is not fully understood. This study compares the effectiveness of quetiapine with haloperidol in treating the hyperactive form of delirium in terms of their effects on morbidity, length of stay in the intensive care unit, and mortality in critically ill patients.
Two-arm parallel-randomized pilot study and to collect data at the Department of Geriatric Medicine at Aalborg University Hospital. The aim is to assess the feasibility of a future randomized controlled study comparing Danish versions of 3D-CAM and 4AT in an acute medical setting. The primary objective is to assess 1) feasibility of obtaining informed consent and recruiting older adults within 24 hours of admission (or surgery) at the Department of Geriatric Medicine, Department of Acute Medicine, or Department of Orthopedic Surgery. Secondary objectives are 2a) to compare feasibility of recruitment and testing in the three different departments, 2b) to inform a preliminary evaluation of validity and reliability of the Danish version of screening instruments, and 2c) to obtain data on variance to support calculating sample size for a full-scale RCT.
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.
