Filter by:Postoperative delirium is a common and important complication in patients. The aim of this study was to investigate whether preoperative anxiety predicted onset of postoperative delirium in elderly patients undergoing orthopaedic surgery, so as to help develop preventive approaches.
Acute post-operatory cognitive dysfunction states are one of the most important complications in older patients after surgery. Two acute cognitive dysfunctions have been described: postoperative delirium (PD) and postoperative subsyndromal delirium (PSSD). Patients who develop delirium, both as a complete or incomplete syndrome, have poor long-term outcomes, such as longer length of hospital stay, institutionalization at discharge, and even higher mortality, and consequently, the human and economic costs significantly increase for the health system. Here the research team will use an observational cohort, investigator blinded in two-center with a primary endpoint to validate the relative alpha power ratio as a predictive biomarker of postoperative cognitive dysfunctions.
Delirium is a very common condition among ICU-admitted patients, and its prevalence is estimated between 30-40%. Delirium is associated with increased morbidity and mortality and future cognitive decline, along with increased ventilation-dependency and other complications. There are multiple risk factors for delirium, including deficiencies of micronutrients. Thiamine deficiency is associated with specific neurological syndromes, including Wernicke and Korsakoff syndromes and Delirium Tremens. Several studies demonstrated significant thiamine deficiency among ICU-admitted patients (prevalence of 30-70%) without known risk factors, such as alcohol dependency. Thiamine deficiency may cause delirium in those patients. Intravenous thiamine had been safely used for decades, for several indications. Lately, thiamine has been advocated for therapy in patients with septic shock, and its use in intensive care units has increased worldwide. Since 2016, thiamine has been routinely administered in our intensive care unit. Considering the theoretical association between thiamine deficiency and ICU-related delirium, the investigators aim to investigate whether the routine use of thiamine has been associated with decreased prevalence of delirium among ICU patients when compared to the pre-routine thiamine administration era.
Postoperative delirium (POD) is a common complication after cardiac surgery,and the pathogenesis is considered imbalance of cerebral oxygen. It may induce the POD incidence by monitering and intervening the low cerebral oxygen desaturation(SCO2) in cardiac surgery .Near infrared spectroscopy (NIRS) will be used for monitering the cerebral oxygen levels.140 case will be included and divided in to trial and control group. The primary outcome is POD In 72 hours after the surgery , which is assessed according to delirium scale .
The purpose of this study is to assess the feasibility of a randomized, double-blind, placebo-controlled pilot trial evaluating the effect of tropisetron on prevention of postoperative cognitive dysfunction in patients after cardiac surgery.
Delirium is one of the most common complications after cardiac surgeries, incidence of which is 20~70%. Causes and pathophysiology of delirium has not been elucidated yet, however, inflammatory response of the nervous system, imbalance of neurotransmitters and ischemia-reperfusion injury of brain tissue are thought to play a big role. 'Neurofilament light (Nfl)' and 'Tau' are proteins that comprise neurons, which are released into blood during acute brain injury. Increased serum concentrations of these markers are acknowledged to be associated with worse clinical outcomes in patients with acute brain injury. These proteins are also closely linked to degenerative changes in the nervous system and cognitive decline in Alzheimer's disease. Therefore, the increase in blood levels of 'Nfl' and 'Tau' may be related to the development of delirium. The aim of this study is to investigate the association between 'Nfl' and 'Tau', serum markers of damage of the nervous system, and the development of delirium after cardiac surgery.
The aim of this study is to investigate the effect of fasting time and blood glucose levels on postoperative agitations in pediatric patients who will undergo outpatient surgery.
180 patients will be randomly divided into two groups 90 patients each using a computer-generated program. Group R: 90 patients will receive a Rivastigmine patch (4.6 mg) 24 h before the operation to 3 days post-operative Group M: 90 patients will receive Melatonin patch (7 mg) 24 h before the operation to 3 days post-operative Patients in the two groups will be compared regarding incidence and severity of delirium on postoperative days 1, 2 or 3 and 7
The prospective, randomized controlled experimental trial investigates the effectiveness of delirium preventive care protocol for hip fracture patients.
This study evaluates the efficacy of melatonin 5mg in the prevention of Delirium in the older adults in emergency department. Half of the participants will receive melatonin 5mg and the other half will use a starch-based placebo.
