Active clinical trials for "Critical Illness"

Postoperative delirium (POD) and postoperative neuropsychological dysfunction are frequently noted in critically ill patients undergoing elective or emergency surgery and treated in the intensive care unit (ICU). Delirium is a serious complication that prolongs hospital stay and contributes to poor outcomes and increased risk of death. The pathomechanisms of delirium are still not very well recognized and there are several theories that seem to explain it. The most important pathomechanisms of delirium are associated with cerebral ischaemia, disorders in acetylcholinergic system, disorders in neuronal plasticity and oxidative stress. Cerebrolysin, a mixture of various peptides obtained from the structural proteins of the pig's brain, possesses strong antioxidative and neuronal protective properties. Cerebrolysin is recommended to treat patients with dementia, after cerebral ischemia and after brain trauma. It has been documented that Cerebrolysin reduces the severity of secondary brain damage after ischemia, improving neuronal plasticity and then cognitive function, and reducing severity of oxidative stress. Based on these properties it can be speculated that Cerebrolysin may reduce the risk of postoperative delirium in patients undergoing elective surgery, which are associated with a high risk of postoperative delirium.

Enhancing the anabolic effect of nutrition in critically ill patients by administering exogenous amino acids.

This is a 2-arm, parallel-group, randomized controlled trial that investigates the effect of combined high protein and early resistance exercise versus usual care on muscle mass, quality and strength, clinical outcomes, functional outcomes and quality of life in mechanically ventilated critically ill patients

Racial disparities result in Black infants in the neonatal intensive care unit (NICU) receiving less breast milk (BM) than White and Hispanic infants.1 BM improves infant health yet mothers of critically ill infants produce insufficient amounts to provide these benefits which is likely due to inadequate daily breast pumping frequency. Black mothers face unique challenges to frequent breast pumping including returning to work earlier, working in facilities with inadequate lactation support, and limited privacy for breast pumping at home. Therefore, the objective of this pilot study is to determine the feasibility and potential benefits of using a discreet, hands-free, wearable breast pump with an associated App that tracks pumping frequency and BM production to increase lactation success in Black mothers of infants admitted to the NICU. Specific aims include (1) evaluate the feasibility of a discreet, hands-free, wearable pump in Black mothers of critically ill infants to increase pumping frequency and BM production and (2) assess whether results indicate a signal of effectiveness supporting a subsequent adequately powered randomized clinical trial (RCT). Following delivery, 40 Black mothers of critically ill infants will be randomized to one of two groups. Group 1 will be provided a discreet, hands-free, wearable breast pump with an associated App and Group 2 will be provided a standard mechanical breast pump with no associated App. Results will be used to revise the intervention and study processes and to estimate outcome measurement variability and effect sizes needed for sample size calculations for an adequately powered RCT.

Elucidate the influence of intense light therapy pretreatment in patients undergoing cardiac surgery. We hypothesize that intense light exposure is associated with the peripheral stabilization of Per2 in human buccal swabs and plasma samples before surgery and with a decrease of Troponin I levels after surgery. In addition, we hypothesize that light therapy leads to Per2 dependent metabolic optimization in the human cardiac tissue. Therefore, a small piece of human heart tissue from the right atrium will be collected during cardiac cannulation, which will be otherwise discarded. Critical illness (being in the intensive care unit) results in circadian malfunction and vessels not working. Vessel function is controlled by the body's circadian clock. Intense light boosts the circadian clock and the vessel function in animal studies. Vessels not working well in critical ill patients results in a myriad of severe diseases (delirium, stroke, heart attack, organ damage etc). Thus we will test if intense light can be used to boost the circadian clock and the associated vessel function in critical ill patients.

Acute skeletal muscle wasting in ICU patients is associated with functional impairment and with increased risk of death. Of what we know today, physical disability can persist up to 5 years. Adequate nutrition is the basis for an optimal recovery for ICU patients and for prevention of muscle wasting. Today, continuous feeding is still the standard enteral nutrition form for patients in the ICU to limit the incidence of aspiration. A study of Serpa et al. and Georgia et al. compared the continuous feeding versus a bolus nutrition with a feeding time of 30 - 60 minutes every 4 hours. They showed no statistical differences in complications between both groups. ProBoNo is a prospective, randomized, controlled pilot study of critically ill patients with a protein- rich formula to explore the impact of continuous or intermittent bolus nutrition on muscle breakdown in ICU patients. The investigators would like to recruit 68 patients during the first 24 hours after surgical intensive care unit admission. Prior beginning of nutrition administration, and on the 7th day thereafter the investigators will perform a muscle biopsy and an ultrasound from the vastus lateralis muscle in both groups. The primary outcome is the time from 6.00 am of the following day after admission until the patient reaches his daily protein's target quantity. Secondary outcomes include the diameter and densitiy of the hamstrings assessed by ultrasound and histology, the process of gastric residual volume, number of diarrhoea events and laboratory findings like glucose, urea and insulin like growth factor (IGF)-1, all compared between the two time points. Intermittent feeding is not only more natural and could help to limit the muscle wasting in ICU patients, it is also easier to handle for the ICU caring medical team. A trial from Georgia et al. in 2007 compared continuous to intermittent enteral nutrition. They found that the intermittently fed patients reached their nutrition goal faster than those being continuously nourished. This might in part be explained by feeding interruptions in the continuous feeding regimen. Presumably, preoperative holding of tube feedings in the continuous nutrition group most commonly caused interruptions. Thus, independently from prevention of muscle breakdown, a bolus nutrition would be more attractive.

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.

Studies have demonstrated that the use of a procalcitonin (PCT)-guided algorithm in combination with clinical judgment was associated with reduced antibiotic use without impacting mortality or treatment failure. Though several studies have evaluated the use of PCT in critically ill patients, there are limited studies that evaluated PCT in patients with cancer and many of the currently available studies have excluded immune-compromised patients. This is a randomized controlled trial that aims to evaluate the impact of a procalcitonin-guided algorithm on antibiotic utilization in critically ill cancer patients with sepsis. In addition, the study aims to evaluate the predictive value of PCT for predicting mortality and positive cultures.

Evaluation and management of intravascular volume are a central challenge for the critical ill patients. Hypotensive patients are commonly resuscitated with intravenous crystalloid fluid as a recommendation for treatment of many shock states. There has been a growing interest in the implementation of lung ultrasound in critical care management in the last decade as it is easy, bedside, non-expensive, non invasive and radiation free. The object of the current study is to assess the ability of lung and inferior vena cava sonography versus pulse pressure variation to predict fluid responsiveness in patients with circulatory failure on mechanical ventilation.

Patients admitted to the intensive care units (ICUs) are an unexpected event that consequently causes physical and psychological problems, including ICU acquired weakness, delirium, sleep disruptions, anxiety, depression, and post-traumatic stress disorder (PTSD). Such consequences may lead to prolonged ICU stay, increased health care, and elevated medical costs. Therefore, mitigating physical and psychological distresses by providing timely effective interventions has become a top concern to optimize critically ill patients' recovery. Investigators aim to design an interactive hand-grip game to improve patients' upper limbs activities and psychological health in patients requiring intensive care.
