Delirium

Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are common complications after surgery and may affect elderly patients in particular. CogCheck, an application for tablet computers, was developed with the intention to assist preoperative risk screening for POD and POCD in surgical patients. The aim of this study is to generate normative data with cognitively healthy participants for the application.

How Common Are Sleep Disorders and Problems With Emergence From Anesthesia in Surgical Patients...

Emergence DeliriumParasomnias

Emergence delirium (ED), also called emergence agitation or post-anesthetic excitement, is defined as a dissociated state of consciousness, occurring on awakening from general anesthesia, in which children exhibit psychomotor agitation, crying and thrashing and are not consolable for a period of time, usually 5-15 minutes. Emergence delirium is a common problem in pre-school children, with estimates of the incidence ranging from 10-70% of children in this age group. These children are agitated, seemingly unaware of their surroundings, and typically do not respond to parents or caregivers. They are therefore at risk for self-inflicted traumatic injury and complications secondary to disruptions of intravenous lines, surgical incisions, or drains. Children with ED typically require more resources in the postoperative period than children who do not exhibit ED. Predicting the likelihood of ED would allow for better allocation of resources in the post-anesthetic care unit (PACU). The peak incidence of ED in children occurs in the same age range at which the peak incidence of parasomnias (PS) occurs. The description of parasomnias is strikingly similar to the description of ED; the American Academy of Sleep Medicine defines parasomnias as "undesirable physical events or experiences that occur during entry into sleep, within sleep or during arousals from sleep." Parasomnias can be diagnosed using a sleep questionnaire. The purpose of this pilot study is to determine the incidence of ED and PS in our population, in order to determine the number of patients necessary to enroll in a larger study to either confirm or reject the hypothesis that ED and PS are correlated.

Longitudinal Cohort Study - for the Treatment of Acute Postoperative Pain and Postoperative Delirium,...

PainDelirium1 more

Adequate pain therapy is important aspect of perioperative care. Sequelae of inadequate pain management are patient dissatisfaction, post-operative nausea and vomiting (PONV), inadequate nutrition, lack of mobilization, and an increased risk for the development of further complications, such as postoperative delirium (POD). The use of patient-controlled analgesia (PCA) systems, which allow patients to self-administer analgesics, has improved pain management. Conventional i.v. PCA and the non-invasive administration of sufentanil sublingual tablets (ZALVISO®) are available. The aim of this investigation is to study patient controlled analgesia systems and to examine the incidence of POD, POCD and postoperative pain.

Risk Factors for Delirium in Critically Ill Surgical Patients

DeliriumIntensive Care Unit Syndrome

Delirium is characterized by changes in mental status, inattension, disorganized thinking, and altered consciousness. Prevalence of delirium in critically ill patients has varied from 20~80% depending on the severity of illness. Despite its high prevalence, delirium is often under-recognized by clinicians due to the difficulties in diagnosis and no interest. Delirium is associated with increased mechanical ventilation days, hospital length of stay, and mortality. The purpose of this study is to analyze the prevalence of delirium and risk factors for delirium in critically ill surgical patients.

Cholinesterase Activity and DeliriUm During Critical Illness Study

DeliriumCognitive Impairment

Delirium is a syndrome of acute brain dysfunction involving attention and cognition that affects up to half of older hospitalized patients and 50%-75% of critically ill ICU patients, such that millions of patients worldwide experience this acute threat to their health and well being every year. One-third to half of critical illness survivors struggle with a dementia-like disorder similar in severity to moderate-to-severe traumatic brain injury or Alzheimer's Disease, and the only proven risk factor that is potentially modifiable is delirium in the ICU. Despite the frequency and impact of delirium in the ICU, little is known regarding the biological mechanisms that lead to this form of organ dysfunction during critical illness. A widely held hypothesis proposes that inflammation is regulated by the cholinergic system, and that this interaction plays a pivotal role whether delirium developments in the setting of acute illness. Acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) are enzymes that hydrolyze the neurotransmitter acetylcholine. Changes in the activity of these enzymes, which can be measured in whole blood, reflect altered regulation of circulating acetylcholine. AChE and BuChE activities have promise as both predictors of delirium (when found to be low at admission) and biomarkers of delirium (when low during serial measurement). Neither of these biomarkers, however, have been studied in the ICU setting where delirium risk is the highest. The current investigation, therefore will be the first to determine the validity of circulating AChE and BuChE activities as biomarkers of delirium during critical illness and subsequent cognitive impairment after discharge. This study will measure whole blood AChE and butyrylcholinesterase BuChE activities within the framework of the ICU Delirium and Cognitive Impairment Study Group's ongoing clinical trials in critically ill patients.

Delirium in Home-dwelling Old People Receiving Home Nursing Care

Delirium

Study the prevalence of delirium among old persons with home-nursing care living in the community. By recruiting the persons in a stable phase, the investigators wish to study the influence of an episode of delirium upon further cognitive and physical function.

Dexmedetomidine Supplemented Intravenous Analgesia in Elderly After Orthopedic Surgery

ElderlyOrthopedic Surgery4 more

Delirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. The investigators hypothesize that, for elderly patients after orthopedic surgery, dexmedetomidine supplemented intravenous analgesia can reduce the incidence of delirium and improve the long-term outcomes.

Post-stroke Delirium Screening

DeliriumIschemic Stroke1 more

For a long time, delirium was considered a merely temporary dysfunction of the brain. Today, it is established that it is a brain disease associated with network dysfunction, neuroinflammation and impaired transmitter homeostasis in a multicausal model. Following an episode of delirium, many patients do not return to their prior level of cognitive and functional performance. In particular, failed or delayed diagnosis with consecutive inadequate therapy contribute to the development of long-term cognitive decline that may ultimately lead to long-term care. Stroke patients are a particularly common delirium-affected population (10-46% depending on severity). Despite the frequency and clinical relevance of delirium in stroke patients, diagnostic characteristics of common screening methods are unknown. Similarly, the clinical phenotype and risk factors of patients who develop delirium have not been adequately described. This study primarily aims to evaluate the diagnostic properties of established screening tools for delirium in a prospective cohort of well-characterised patients following ischemic cerebral events (either transient or manifest stroke). Secondary outcome criteria include predictors of post-stroke delirium (PSD) such as stroke location and size, pre-stroke cognitive functioning, ability to participate in daily routine activities and medical conditions.

Subsyndromal Delirium in Intensive Care Unit

Delirium

Subsyndromal delirium (SSD) is a condition characterized by a less severe cognitive impairment in comparison to delirium. To date there is no published consensus on SSD definitions and has been commonly reported as an intermediate stage between delirium and normal mental states. SSD encompasses some of the delirium symptoms, and has been diagnosed with Intensive Care Delirium Screening Checklist scale (ICDSC) and Confusion Assessment Method-ICU (CAM-ICU). The objective of this study is to identify subsyndromal delirium prevalence, the association between SSD and clinical outcomes and understanding the relationship between SSD and conversion to delirium. The relevance of this study is understanding of subsyndromal delirium in ICU, namely the importance of early presentations of acute brain dysfunction in the patients outcome.
