Filter by:This is a randomized control trial to determine if early cognitive training and rehabilitation improve 4-month cognition in hospitalized older (>=65 years old) delirious patients with and without Alzheimer's disease and related dementias. Enrolled patients will be randomized to receive cognitive intervention versus usual care at a 1:2 allocation ratio. Patients assigned to the cognitive intervention group will receive cognitive training daily during hospitalization and cognitive rehabilitation weekly for 12 weeks after hospital discharge. Patients will be evaluated for global cognition (primary outcome) and secondary outcomes at 4-months.
This study will investigate the incidence of postoperative POD in patients undergoing non cardiac surgery under general anesthesia with and without the implementation of the BIS monitoring.T
Introduction. Initiation of acute kidney replacement therapy (KRT) is common in critically ill adults admitted to the intensive care unit (ICU), and is associated with increased morbidity and mortality. KRT has been linked to poor neurocognitive outcomes, leading to a reduced quality of life, as well as increased utilization of healthcare resources. Adults initiated on dialysis in the ICU may be particularly at risk of neurocognitive impairment, as survivors of critical illness are already predisposed to developing cerebrovascular disease and cognitive dysfunction over the long-term relative to healthy controls. Regional cerebral oxygen saturation (rSO2) may provide a critical early marker of long-term neurocognitive impairment in patients in this population. The INCOGNITO-AKI study aims to understand cerebral oxygenation in patients undergoing KRT, either continuous or intermittent, in the ICU. These findings will be correlated with long-term cognitive and functional outcomes, as well as structural brain pathology. Methods and analysis. 108 patients scheduled to undergo treatment for acute kidney injury with KRT in the Kingston Health Sciences Centre ICU will be recruited into this prospective observational study. Enrolled patients will be assessed with intradialytic cerebral oximetry using near infrared spectroscopy (NIRS). Delirium will be assessed daily with the Confusion Assessment Method-Intensive Care Unit (CAM-ICU) and delirium severity quantified as cumulative CAM-ICU-7 scores. Neurocognitive impairment will be assessed at 3- and 12-months after hospital discharge using the Kinarm and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Structural brain pathology on MRI will also be measured at the same timepoints. Driving safety, adverse events, and medication adherence will be assessed at 12-months to evaluate the impact of neurocognitive impairment on functional outcomes. Ethics and dissemination. This study has been approved by the Queen's University Health Sciences and Affiliated Teaching Hospitals Research Ethics Board (Approval number: DMED-2424-20). Results will be presented at critical care scientific conferences and a lay summary will be provided to patients and families in their preferred format.
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.
Postoperative delirium (POD) is the most common adverse neurologic complication that can occur in patients of any age. Its incidence varies across age groups and is substantially influenced by patient-related risk factors. POD occurs in 17%-61% of major surgical procedures. Several risk factors which contribute to the development of POD include age more than 60 years, pre-existing cognitive dysfunction, presence of comorbidities, sensorial deficits, malnutrition, polypharmacy, impaired physical mobility and frailty. Postoperative delirium has several wide ranging and adverse outcomes that are consistently associated with delirium such as mortality, increased length of hospital stay, and increased hospital costs. A recently devised tool for rapid assessment of delirium is the 4 A's test. It has now been validated for identifying delirium in the surgical population. The proposed prospective observational study will be conducted on 150 patients belonging to ASA Physical Status I-III of either sex, scheduled to undergo non-cardiac surgery under general anaesthesia (GA), requiring at least 24 hours of postoperative inpatient care. This prospective, observational study aims to evaluate the incidence, risk factors and outcomes of postoperative delirium in elderly patients more than 65 years of age undergoing non-cardiac surgery.
Preventing emergent delirium in pediatric ambulatory surgery through preoperative use of intra-nasal Dexmedetomidine and oral Midazolam.
Rationale: Delirium is a common and severe complication after neurosurgical procedures. Music before, during and after surgical procedures has proven its effectiveness in reducing pain, anxiety, stress and opioid medication in surgical patients. These symptoms belong to the main eliciting factors for developing delirium. Effective preventive therapy for delirium is not available. The investigators hypothesize that music listening, being a sustainable intervention with negligible risk of side effects, can lower delirium incidence among neurosurgical patients, resulting in reduction of in-hospital stays, healthcare costs and post-operative morbidity and mortality. Objective: To assess the effect of peri-operative music on post-operative delirium in patients undergoing a craniotomy. Study design: Single-centre prospective randomized controlled trial. Study population: Adult patients undergoing a craniotomy at the Erasmus MC in Rotterdam. Intervention: Recorded music, with headphones or earphones, before, during and after surgery. Main study parameters/endpoints: Diagnosis of post-operative delirium screened by the DOS score confirmed by the consultant psychiatrist following the DSM-V criteria.
The SARS-CoV-2 epidemic is leading to a large number of patients in intensive care units due to severe hypoxemic pneumonia. After an acute phase that may require controlled mechanical ventilation and deep sedation, removal of sedation often reveals a pathological awakening in the vast majority of patients. This encephalopathy state remains, to date and to our knowledge, unexplained. Clinical features do not appear to fully correlate with regular delirium. This encephalopathy might be explained by deep and prolonged hypoxemia, a wide use of sedation drugs, systemic inflammation or the hostile ICU environment.
Post-operative delirium happens when patients wake up from anesthesia. Patients experiencing post-operative delirium are very confused, not being able to think or function "normally". These patients are hard to take care of and they tend to have more dementia as they age compared to patients who don't experience post-operative delirium. Intranasal insulin has been shown to reverse confusion associated with Alzheimer's disease (humans) and AIDS (mice). Intranasal insulin has been safely administered to 1092 patients in 38 different studies. There were no cases of clinically low blood sugar and a few cases of mild nasal irritation that happened also with salt water when the subjects received multiple intranasal doses. No one has tried to reverse post-operative delirium with intranasal insulin. The delirium associated with Alzheimer's Disease and AIDS have very similar symptoms and what happens in the brain is very similar also. The investigators intent is to administer intranasal insulin to patients exhibiting post-operative delirium in order to reverse the symptoms because the investigators think that the three disease states are closely related and intranasal insulin has had some success in reversing the delirium in the other two disease states.
Emergence delirium (ED) is a manifestation of acute postoperative brain dysfunction that occurs with a relatively high frequency after pediatric anesthesia. The incidence varies depending on the diagnostic criteria used and the combination of administered anesthetic drugs. The use of sevoflurane has been identified as one of the most important risk factors. In the investigators' study，the researchers conducted the current study to investigate whether remimazolam can reduce incidence of ED.
