Filter by:The goal of this multi-centre phase I/II open-label, single-arm study is to determine the feasibility, optimal dose, and preliminary efficacy of dexmedetomidine to manage agitated delirium among patients near the end of life followed by a palliative care provider in a non-monitored setting. Fifty patients will receive dexmedetomidine (0.4 mcg/kg/hour, titrated up to 1.0 mcg/kg/hour) subcutaneously. Feasibility (recruitment rate, cost), safety (rate of adverse events), dosing, and preliminary efficacy (agitation, delirium severity) will be measured.
Aim: to investigate whether the 4C Mortality score, which measures the severity of COVID-19, and the CAM-ICU 7 score , which measures the severity of delirium, in ICU. To compare two scores in terms of the number of days without intubation and 28 day mortality rates in ICU.
Ventilated pediatric patients are frequently over-sedated and the majority suffer from delirium, a form of acute brain dysfunction that is an independent predictor of increased risk of dying, length of stay, and costs. Universally prescribed sedative medications-the GABA-ergic benzodiazepines-worsen this brain organ dysfunction and independently prolong duration of ventilation and ICU stay, and the available alternative sedation regimen using dexmedetomidine, an alpha-2 agonist, has been shown to be superior to benzodiazepines in adults, and may mechanistically impact outcomes through positive effects on innate immunity, bacterial clearance, apoptosis, cognition and delirium. The mini-MENDS trial will compare dexmedetomidine and midazolam, and determine the best sedative medication to reduce delirium and improve duration of ventilation, and functional, psychiatric, and cognitive recovery in our most vulnerable patients-survivors of pediatric critical illness.
This research will test the hypothesis that immune system disequilibrium / dysfunction explains why preoperative cognitive impairment is a strong predictor of postoperative morbidity in older surgical patients. The investigators propose that cognitive impairment influences surgical morbidity because of underlying immune disequilibrium / dysfunction (risk marker) and that this shapes the immune response to surgery and defines immunological hallmarks of postoperative morbidity (disease marker). The overarching goal of this application therefore is to define and better understand the clinical immunology underlying the relationship between cognition and geriatric surgical morbidity.
The specific aim of the study will be to set up a perioperative database to longitudinally track the progress of elderly patients undergoing major surgery from the preoperative period to five years postoperatively. This database will form the foundation of a programme that will be sustainable through future grants to implement clinical strategies to improve outcomes.
The global pandemic caused by the SARS-CoV-2 virus is confronting the German health system with a novel pathogen. This means that a timely evaluation of all available results is required. In the field of intensive care in particular, there are significant gaps in knowledge, particularly with regard to delirium. In this respect, this study also serves directly to investigate the pathways of delirium outcome in COVID-19 patients.
Inhalation anesthesia is the most frequently used technique and is performed in around 70% of surgeries worldwide. Sevoflurane is the most frequently used halogenated anesthetic and is used in 2/3 of the cases. The anesthetic strength of inhalation agents was established in the classic work of Eger and colleagues who determined the minimum alveolar concentration (MAC) of an inhaled anesthetic at atmospheric pressure, necessary to prevent a motor reaction in response to a pain stimulus in 50% of patients. Agitation is a frequent anesthesia complications and it not only lengthens the period of post anesthetic awakening and need for advance monitoring of the patient, but may be a predisposing factor in the development of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) which are independent predictors of increased mortality, prolonged treatment in the ICU and hospital, and prolonged social adaptation of the operated patients.(The ability of the patient to serve themselves independently.). There is a fairly popular point of view that there is no specific prophylaxis or treatment of postoperative agitation. However, a variant of anesthesia induction with sevoflurane was recently proposed, which reduced the frequency of agitation in children from 24.7% to 4.4%. The technique consisted in interrupting anesthesia at the moment of loss of consciousness, awakening the patient and subsequently performing re-induction. Since this technique might be time consuming in the busiest period of a surgical theatre and not safe if performed with the airways still unsecured it is advisable to shift the Wash In/Wash Out procedure to the stage of awakening at the end of surgery.
Delirium is one of the most common manifestations of cerebral dysfunction in severely ill patients. The international guidelines for the prevention of delirium in intensive care recommend the daily application of environmental, behavioral and pharmacological strategies. In the case of the agitated form of delirium, experts recommend the use of low-dose neuroleptics and α-2 agonists to control psychotic manifestations rather than traditional sedatives (mainly benzodiazepines) that can clearly aggravate delirium. Currently, two pharmacological α-2 agonists, clonidine (Catapressan®, Boehringer Ingelheim) and dexmedetomidine (Dexdor®, Orion Corporation), are marketed and commonly used in intensive care for their sedative, anxiolytic and analgesic properties. To our knowledge, no studies have compared the effects of clonidine and dexmedetomidine in agitated delirium in intensive care patients. Therefore, our goal is to compare the safety of clonidine and dexmedetomidine (in terms of bradycardia and / or hypotension) in addition to standard treatment in the context of agitated delirium in intensive care patients.
As patients with terminal illness enter the dying phase, they may experience symptoms of restlessness, agitation, or cognitive disturbance, known as terminal delirium. In community care, pharmacological therapies are utilized to manage the syndrome, the most commonly used being neuroleptics haloperidol and olanzapine. However, there is currently a dearth of studies on the efficacy and safety between haloperidol and olanzapine in the community palliative care setting; existing studies involve non-terminal patients in the hospital suffering from acute delirium. To fill this gap, an open-label randomized clinical trial is proposed to compare the effects of haloperidol and olanzapine in the management of terminal delirium in home hospice patients who are imminently dying. Key outcome measures are the reduction of delirium symptoms and the reduction of agitation. Secondary outcome is comparing the adverse effect burden on patients.
The purpose of this study is to determine if positive imagery therapy while using ketamine in procedural sedation reduces the number of emergence reactions and impacts pre and post-procedural anxiety.
