Postoperative Delirium: EEG Markers of Sleep and Wakefulness
Postoperative DeliriumPostoperative delirium is a condition in which patients develop temporary difficulties in maintaining attention and thinking clearly. These new problems can appear after surgery and change throughout the day. This confusion can last several days. The overall purpose of this study is to measure brain activity during sleep and wakefulness to learn about their relationships to delirium after surgery. While participants may not feel like their normal self during the study, they are in the best position to help us learn how to improve the recovery of brain function and sleep in others having surgery. The investigators need to learn from those who have and have not become confused after their surgical procedure.
Recommendations and Alerting for Delirium Alleviation in Real-Time (RADAR)
DeliriumThis is a pilot randomized controlled trial that will test whether a multicomponent decision support system will improve the postoperative environment for neurocognitive and clinical recovery in older, high-risk surgical patients. Decision support systems will be tested that provide targeted alerts and recommendations to the Hospital Elder Life Program and family members for delirium prevention.
Assessment and Management of Pain, Agitation, Delirium and Sleep Deprivation (PADS) in ICU by PADS...
PainAgitation on Recovery From Sedation1 moreThe investigators proposed that pain, agitation, delirium and sleep deprivation protocol (PADS) will help improve the patients' outcomes (shortening ICU length of stay, improving ventilator free days, increasing delirium free days) in critically ill patients, a university hospital, Thailand.
Avoidance of Delirium in Older Patients After Major Non-cardiac Surgery
DeliriumThis study is designed to compare the incidence of postoperative delirium in older patients after major non-cardiac surgery with different perioperative hemodynamic managements: a goal directed hemodynamic management group and a control group
Dexmedetomidine to Lessen Intensive Care Unit (ICU) Agitation
DeliriumThe primary aim of the DahLIA trial is to determine, in patients with ICU-associated delirium and agitation who are otherwise pathophysiologically stable (as defined), the number of ventilator-free hours in the incident ICU admission in the 7 days following commencement of trial medication, in patients randomised to receive dexmedetomidine or placebo while receiving all other aspects of standard care. The null hypothesis assumes no difference in the median number of ventilator-free hours in this ICU admission in the following 7 days, between patients receiving dexmedetomidine and placebo for ICU-associated agitation and delirium.
Intelligent Intensive Care Unit
DeliriumConfusionDelirium, as a common complication of hospitalization, poses significant health problems in hospitalized patients. Though about a third of delirium cases can benefit from intervention, detecting and predicting delirium is still very limited in practice. A common characterization of delirium is change in activity level, causing patients to become hyperactive or hypoactive which is manifested in facial expressions and total body movements. This pilot study is designed to test the feasibility of a delirium detection system using movement data obtained from 3-axis wearable accelerometers and commercially available camera with facial recognition video system in conjunction with electronics medical record (EMR) data to analyze the relation of whole-body movement and facial expressions with delirium.
Predicting the Risk of Post-operative Delirium: Use of Neuropsychology, Serum and CSF Biomarkers...
DeliriumThe purpose of the study is to determine if pre-operative neuropsychological characteristics, apolipoprotein E4 status and/or cerebrospinal fluid (CSF) and serum biomarkers can predict those most at risk of post-operative delirium. Patients over the age of 65 years undergoing elective primary hip or knee arthroplasty in Musgrave Park Hospital are invited to take part. Participants undergo a pre-operative neuropsychological assessment which is repeated 6-12 weeks post-operatively at the time of surgical review appointment. At the time of surgery advantage is taken of the necessary venous cannulation and spinal anaesthetic to gain venous blood and CSF samples respectively. Venous blood is also sampled post-operatively. Patients are assessed daily for delirium, using the Confusion Assessment Method, until discharge. The association between delirium and subsequent cognitive decline is now well established in the literature. It is not yet clear whether this is solely because delirium following elective surgery indicates a previously unrecognised neurodegenerative process or whether the delirium itself exerts an additional pathophysiological insult. In order to investigate this, a follow-up study of these participants, approximately 8 years later is currently being conducted. Neuropsychological assessment and venous blood sampling will be repeated with consenting participants. Furthermore, the significance of subtle symptoms, not sufficient to fulfil the criteria for delirium and known as subsyndromal delirium, in relation to cognitive function years later will be analysed.
Deep Neuromuscular Block on Cytokines Release and Postoperative Delirium
Hip FracturesThe purpose of the study is to determine the relationship between the degree of neuromuscular block, the release of cytokines and clinical outcomes in elderly patients undergoing orthopedic surgery. Investigators hypothesize that deep neuromuscular blockade decreases the release of cytokine and the incidence of postoperative delirium in elderly patients undergoing orthopedic surgery, compared with moderate neuromuscular blockade.
Shaping Anesthetic Techniques to Reduce Post-operative Delirium
DeliriumLumbar Radiculopathy2 moreThe purpose of this study is to determine if light sedation with spinal anesthesia reduces the incidence of delirium compared to receiving general anesthesia during spinal surgery in older adults.
Risk Factor of POD and POCD After Cardiac Surgery
Postoperative DeliriumPostoperative Cognitive DysfunctionPostoperative delirium (POD) and postoperative cognitive decline (POCD) are common after surgeries in the elderly, especially after cardiothoracic surgery. These conditions are associated with adverse short- and long-term outcomes. Multiple conditions in the perioperative period have been proposed as risk factors of POD and POCD. Incidences vary across institutions due to differences in screening and diagnostic tools.
