Delirium, Intraoperative Cerebral Perfusion and EEG Abnormalities After Total Hip Arthroplasty

DeliriumHip Arthroplasty1 more

The overall objective of this study is to test for perturbations in intraoperative electroencephalogram (EEG) , cerebral blood flow (CBF), cerebral metabolic rate of oxygen consumption (CMRO2), oxygen extraction fraction (OEF), and serum and cerebral spinal fluid biomarkers associated with delirium in high risk population having elective hip arthroplasty at Penn Presbyterian Medical Center (PPMC).

Incidence and Characteristics of Postoperative Cognitive Dysfunction in Elderly Quebec Francophone...

DeliriumCognitive Impairment4 more

The purpose of this study is to determine what percentage of patients have cognitive problems (for example, memory or concentration difficulties) after surgery and anesthesia, what the characteristics of these problems are, and whether they persist over time. In particular, the investigators want to study this in the French-speaking Quebec population with cognitive evaluation tools adapted for this population.

Melatonin for Delirium Prophylaxis

Delirium

Delirium is a common complication of illness especially among the elderly with serious sequelae including increased mortality, morbidity and length of stay. This neuropsychiatric emergency has key features including acute onset, fluctuating level of consciousness, poor attention and cognitive deficits with a presentation which may include hallucinations and delusions. A critical precipitating and maintaining feature of delirium is disrupted sleep. Melatonin is a widely available natural health product with evidence in normalizing circadian rhythms and sleep. There is also preliminary evidence that melatonin can be used to prevent the development of delirium in hospitalized patients. We hypothesize that daily administration of melatonin (1.5mg) in the evening, beginning at first admission to hospital and continuing for 14 days, will lead to decreased rates of delirium compared to placebo-treated comparison subjects.

Cognitive Impairment Following Elective Spine Surgery

Cognitive ImpairmentPostoperative Delirium1 more

Older people are a rapidly growing proportion of the world's population and their number is expected to increase twofold by 2050. When these people become patients that require surgery, they are at particular high risk for postoperative delirium (POD), which is associated with longer hospital stays, higher costs, risk for delayed complications and cognitive dysfunction (POCD). Having suffered an episode of delirium is furthermore a predictor of long-term care dependency. Despite these risks, an increasing number of elderly undergo major elective surgery. This is reflected by the frequency of elective spinal surgery, in general, and instrumented fusions, in particular, which has markedly increased over the past few decades. It is yet insufficiently understood, which, particularly modifiable, factors contribute to the development of POD and POCD following these major but plannable surgeries. A better understanding of risk factors would facilitate informed patient decisions and surgical strategies could be tailored to individual risk profiles.

Impact of Alarm Reduction on Delirium in ICU

Delirium

Delirium is an acute and fluctuating disturbance of consciousness and can occur in 80% of critically ill patients. Delirium is more frequent in mecanically ventilated patients and is associated with longer hospital stay, increased cognitive impairment and mortality. On the occasion of the change of the monitors in the ICU ward, allowing a total withdrawal of alarms in patients room, this study evaluates the prevalence of delirium before and after the alarm withdrawal. During the first period the patients will be monitored as usual, and during the second period patients will be monitored without alarms ringing in patients room. Delirium will be screened with a validated, clinical tool.

Ramelteon vs Placebo for Prevention of Delirium and Improvement of Sleep in Hospitalized Older Adults...

Delirium in Old Age

This study evaluates whether Ramelteon can prevent delirium, decrease the severity of incident delirium and improve sleep wake cycle in hospitalized elderly surgical patients. Half of the patients will be assigned to Ramelteon, while other half will be assigned to placebo.

MindfulGarden in Treatment of Hyperactive Delirium in a Hospital Setting

Hyperactive Delirium

This pilot study is designed to address feasibility for a larger randomized control clinical study that will determine the efficacy of exposure to the MindfulGarden - an interactive digital technology - in reducing hyperactive delirium in hospitalized older adults.

The Effectiveness of Acupuncture for Complications in Critically Ill Patients

DeliriumAgitation4 more

Introduction: Intensive care unit (ICU) is a special department in the health care facility. Although with high development of modern medicine nowadays, the average mortality rate in ICU is still around 7 to 20 %. There are a few tricky problems that intensivists and ICU nurses faced very often, including ICU delirium, arrhythmia and poor digestion problem that will all affect the mortality and morbidity rate of critical care patients. Methods: A randomized control trial will examine the effect of press tack acupuncture vs. press tack placebos. The patients will be randomly divided (1:1) into one of two groups. A total of 80 ICU patients will have to meet the following criteria: age 20-90, newly ICU admission(<48 hours), APACHE score <30, one or no inotropic medicine use, FiO2< 60%. Three interventions will be given in each group. The main outcomes will be the incidence of arrhythmia, delirium, and poor digestion and the severity of pain. We will also record ICU mortality, ICU stays and hospital days.
