Filter by:The investigators are performing this research study to understand the role of sleep disturbance on the incidence/severity of delirium after surgery. The investigators will study the brain using a polysomnography device (PSG), which records the brain's electrical activity during sleep.
This research study proposes to conduct an open label, feasibility study administering prophylactic oral haldol to patients undergoing a hematopoietic stem cell transplant (HSCT). The study will address the following research aims: 1) To demonstrate the feasibility of enrolling HSCT patients in a prophylactic medication trial, 2) To determine the tolerability of oral haldol in HSCT patients and 2) To compare rates of delirium in HSCT patients who receive prophylactic haldol with an untreated historical control group.
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.
The purpose of this study is to determine if using an over-the-counter, commercially available sleep noise machine playing pink or white noise will reduce the incidence of delirium in hospitalized patients over the age of 65. Delirium is an acute change in cognition which commonly occurs in hospitalized older adults, and is linked with sleep-wake cycle disturbance. Delirium is associated with increased morbidity and mortality as well as longer hospital stays. This project will record delirium screening scores for those receiving the intervention and comparing them to baseline data. Reducing delirium rates using a noninvasive, inexpensive method in a hospital setting could have a significant impact on patient outcomes and potentially reduce costs associated with longer hospital stays. It is anticipated that white/pink noise played at night will decrease rates of delirium in hospitalized older adults.
Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.
This prospective, randomised, double blinded, controlled clinical trial will be conducted in 147 patients between 60 yr and 70 yr , ASA physical status II and III, undergoing CABG. Patients will be randomly allocated to either dexmedetomidine or clonidine (control) groups .Upon arrival to ICU, in the dexmedetomidine group, patients will receive an infusion of 0.5-0.7 μg/kg/h then 1.4 μg/kg/h if Richmond assessment sedation score from +1 to +4 Taking into consideration if the heart rate less than 60 per minute or persistent hypotension reduce infusion rate by 0.2 μg/kg/h. Once the patient will be extubated, wean the infusion by 0.1μg/kg/h till reaching 0.2μg/kg/h. Slow the weaning rate if evidence of withdrawal reactions as agitation or hypertension occur. In clonidine group, the patients will receive 0.5μg/kg then 0.1-0.2 μg/kg/h.Primary end point of the study is the incidence of delirium.The secondary endpoints will be the the duration of extubation, the length of ICU stay, need for inotropic support or vasopressors, hospital stay , mean arterial blood pressure and heart rate , hospital mortality rate , all additional sedatives including overall doses of morphine and haloperidol the incidence of adverse events as bradycardia
We designed a prospective, double blind, randomized, controlled versus placebo study to evaluate the efficacy of nightly low dose of Dexmedetomidine infusion to promote sleep and lower delirium in a population of post cardiac surgery patients. This population is characterized by longer ICU stay, more physical restraints such as catheters and drains, pain and sleep deprivation. It is associated with higher prevalence of Delirium and agitation leading to exposure to severe agitation related adverse events.
There has been some recent evidence to support the use of earplugs and eye masks to prevent delirium, but the existing studies have been small, have not been thoroughly replicated, and have only been conducted with intensive care unit (ICU) patients. Therefore, we propose to conduct a single-arm pilot study for an eventual single-blinded randomized controlled trial designed to assess the efficacy of earplugs and eye masks worn at night for prevention of delirium in a population of general medicine inpatients over the age of 65. The primary outcome will be incidence of delirium as measured by Confusion Assessment Method (CAM). In this pilot study, we will assess feasibility and will not perform any statistical comparisons. In the subsequent randomized controlled trial, we will be comparing the hazard rates on an intention-to-treat basis. Secondary outcomes will be exploratory and include length of stay, cost data, and use of pharmacologic interventions for sleep, delirium, or agitation. There are no physical risks and no cost to the subjects in this study.
Objective: To evaluate the effect of care bundle on prevention of delirium among elderly patients with hip fractures. Methods: A prospective randomized case control study was performed for 80 patients (≥65 years) with hip fractures treated surgically according to their ages and the type of fractures from March 1th of 2017 to June 30th of 2017．There were 11 males and 69 females, with the age of (79.3±7.84) years. Confusion assessment method (CAM) was applied to diagnose delirium after surgery, the subjects were randomized divided into experimental group (n=43) and control group (n=37). The parameters next were recorded and analyzed, including age, gender, type of fractures, type of internal instrument, amount of bleeding, time between injured to surgery, time length of operation, type of operation, VAS, incidence of delirium, perioperative complications and adverse events.
A 30 alcohol dependent patients were divided into A: Treatment group and B: Placebo group using simple randomization technique. (Liver function tests) GGT, ALT and AST levels and MCV (Mean corpuscular volume) at admission and 2 weeks later were estimated. Daily withdrawal symptoms were assessed using the Clinical Institute Withdrawal Assessment scale (CIWA-Ar) and DTs by Delirium Observation Screening (DOS) Scale (version 0 - 1). The data collected from the two groups were compared.
