Correlation Between Blood Biomarkers and Postoperative Delirium in Elective Non-Cardiac Surgery....

Postoperative DeliriumElective Non-Cardiac Surgery

More than 20% of patients over 60 years old develop postoperative delirium following non-cardiac surgery . Delirium increases morbidity and mortality , and may lead to long-term cognitive impairment . The underlying mechanisms behind delirium are not understood , endothelial dysfunction and disruption of the blood brain barrier (BBB ) caused by perioperative systemic inflammation may play a important role in the development of delirium . This study intends to evaluate the relationship between neuroinflammation and postoperative delirium in elderly non-cardiac surgery patients . The results of the study are to identify risk factors and explore the biomarkers most closely linked to each step of the proposed pathway .

Association Between qEEG Measure and Post-Operative Cognitive Dysfunction (POCD) and Postoperative...

Cognitive Dysfunction

Cognitive complications after major surgery are a common phenomenon. The incidence of Postoperative Cognitive Dysfunction (POCD), may vary from 5% to 25% in adult patients, depending on different risk factors. Age has been strongly associated with cognitive complications. POCD is a prolonged decline in cognitive function that appears after surgery as compared with preoperative functions. In order to classify evaluate POCD, it requires at least 2 measurements. A baseline, completed before surgery and a second measurement, post surgery. In light of the high prevalence of POCD and the difficulties in its prediction, NeuroIndex has developed a quantitative EEG system and software that aim to produces risk predictor index (IS) for POCD. This study aims to evaluate the relationship between the software produced predictor index and the actual POCD events. The qEEG will be monitored during the surgery in addition to the routine clinical practice in operating rooms. POCD will be evaluated using Montreal Cognitive Assessment test (MoCA) prior and post surgery.

Perioperative Electroencephalography Characteristics of Postoperative Delirium in Elderly

Postoperative Delirium

The investigators aim to identify preoperative Electroencephalogram (EEG) markers indicating patients at risk to develop postoperative delirium (POD), so that the anesthetist may adjust medications and dosages in order to avoid POD. Second, the investigators aim to specify intraoperative EEG signatures and EEG states that are related to POD and long-term cognitive dysfunction, again to enable physicians to adapt their procedure. Third, the investigators aim to identify EEG signatures during stay in the recovery room that is directly related to POD, and may therefore be used as diagnostic tool, as well as a predictor for the development of long-term cognitive deficits (POCD).

Discovery for Biomarkers and Risk Factors for Postoperative Delirium in Elderly Patients With Spine...

Spinal Disease

Introduction: With the increase of the elderly population, the number of elderly patients undergoing surgery is increasing, and postoperative delirium is 11-51% depending on the type of surgery. In recent cohort studies have shown that delirium might reduce cognitive function and develop dementia. Since delirium is difficult to treat, the key to treatment is prevention, and about 40% is prevented when prophylactic intervention is applied. However, delirium is difficult to diagnose and difficult to predict, therefore, biomarkers are needed to diagnose and prevention. Exosome and brain efficiency test(electroencephalogram, and pulse wave test) have the potential of simple biomarkers that can diagnose postoperative delirium and predict cognitive decline. Purpose: The purpose of this study is to investigate the risk factors affecting delirium in the elderly who have spinal surgery and to search for biomarkers of delirium for early detection and prevention of delirium.

A Survey of Management of Analgesia, Sedation and Delirium in ICU Patients in China

Delirium on EmergenceAnalgesia1 more

In 2018, the severe medicine branch of the Chinese Medical Association and the American Society of severe medicine successively updated the pain and sedation guidelines for severe patients (PADIS guidelines). In addition to the update of the original evaluation and management of pain and sedation and delirium, the new guidelines also increased the monitoring and management of early activities and sleep quality for severe patients. Therefore, it is necessary for us to investigate the compliance of the new guidelines for analgesia, sedation and delirium management among the medical staff of critical care, so as to find out the existing problems in the management of analgesia, sedation and delirium in critical care patients, and find solutions to improve the overall quality level of our management of critical care patients

Impact of Anesthesia Technique on Post-operative Delirium After Transcatheter Aortic Valve Implantation...

DeliriumPost-Op Complication2 more

Aortic stenosis is a frequent valvulopathy in Europe and North America. It occurs mainly over 65 years (2-7% of the population over 65 years). Treatment of symptomatic stenosis is an indication of aortic valve replacement. For patients with high surgical risk (EuroSCORE II> 6), TAVI (Transcatheter Aortic Valve Implantation) is recommended. This type of procedure concerns elderly patients (75-80 years on average in the literature) therefore the anesthesia technique must be optimal. The postoperative complications are, on the one hand, well-described surgical complications (Cardiogenic shock, bleeding, rhythm disorders, renal insufficiency) and, on the other hand, those related to anesthesia which are less well characterized. There is no consensus on best anesthesia technique for TAVI procedure managment. Between teams practices are different. It may consist of general anesthesia (GA) or local anesthesia with sedation (LASed). Elderly anesthesia has specific complications, including acute cerebral disturbances (delirium) usually occurring within 24 to 48 hours postoperatively and up to 7 days. It is recommended to screen delirium for patients admitted in intensive care using the CAM-ICU scale. The aim of the study is to observe the impact of the anesthesia technique (GA versus LASed) on delirium in post-operative aortic valve replacement with TAVI procedure

Postoperative Cognitive Dysfunction in Elderly Urologic Oncology Patients (POCD)

Postoperative Cognitive DysfunctionPostoperative Delirium1 more

Postoperative cognitive changes are more common in elderly patients, which can result in poor quality of life, loss of workforce, disability, early retirement, physical-social dependence, increased health care cost and premature mortality. Postoperative cognitive complications are also quite common in extensive oncological surgeries. In this study, our aim is to evaluate the relationship between the development of postoperative cognitive dysfunction (POCD) in geriatric urologic oncology patients with brain injury and inflammatory markers [S100 β, neuron specific enolase (NSE), interleukin 6 (IL-6) and high mobility group box-1 (HMGB-1 protein)].

Association Between Burst Suppression During Anesthetic Induction With Postoperative Delirium in...

Postoperative Delirium

The population over 65 years of age will be increasingly exposed to surgical procedures that require general anesthesia. Postoperative delirium is one of the main causes of preventable postoperative morbidity in the elderly population and is a frequent event after cardiac surgery with extracorporeal circulation. The excess administration of anesthetics that potentiate the Gamma Aminobutyric A receptor, such as propofol, are related to an intraoperative electroencephalographic pattern called burst suppression that has been associated with postoperative delirium. It is unknown whether this pattern is secondary to a relative overdose of anesthetics or rather corresponds to a characteristic of a vulnerable brain that is suppressed at doses at which other patients are not. Our objective will be to determine whether burst suppression in people over 65 years of age during a standardized anesthetic induction with propofol for cardiac surgery with extracorporeal circulation is associated with postoperative delirium compared to older people who do not present it.

Factors Affecting the Incidence of Postoperative Delirium in Frail Elderly

Postoperative Delirium

Postoperative delirium has been found to be associated with increased risk of future neurocognitive decline and mortality especially in elderly patients. Similarly, Frailty has been found to be associated with an increased risk of postoperative complication including delirium in the elderly.The purpose of this study is determine the factors affecting the incidence of postoperative delirium in frail elderly undergoing non-cardiac surgery in the Singapore population.
