Noninvasive Assessment of Tissue Perfusion Status in Critically Ill Pediatric Patients
SepsisShockInvestigators are conducting research about oxygen levels in the body and whether it is possible to use a device to measure oxygen in the body's tissues noninvasively, without blood draws or a catheter (a plastic tube placed in a vein). Investigators would like to know how this device compares to standard measurements using blood from a catheter. This may help treat patients who may not be getting enough oxygen to their body.
Sup-Icu RENal (SIREN)
Critical IllnessAcute Kidney Injury3 moreData show that episodes of bleeding may often be observed in critically ill patients with dialysis-dependent acute renal failure (ARF) on renal replacement therapy (RRT). From a clinical perspective, patients with dialysis-dependent ARF and end-stage renal disease (ESRD) may be considered a high risk population in regard to e.g. development of gastrointestinal (GI-) bleeding. In the current prospective subanalysis "SIREN" of the randomized placebo-controlled clinical trial "SUP-ICU" (NCT02467621), the investigators seek to elucidate whether the subpopulation of critically ill patients with acute kidney injury requiring renal replacement therapy (RRT) benefit from prophylactic treatment with a proton-pump-inhibitor such as pantoprazole.
Does GM-CSF Restore Neutrophil Phagocytosis in Critical Illness?
Critical IllnessSepsis1 moreDespite the introduction of multiple preventative measures rates of hospital acquired infection in the intensive care unit remain high. New approaches to tackling this problem are required. The neutrophil (a type of white blood cell) is the key cell fighting bacterial and fungal infection in the body. This research group has already shown that the majority of patients on intensive care have neutrophils which don't ingest germs effectively and are therefore less able to fight infection. These patients, whose white blood cells don't work properly, are much more likely to develop a second infection whilst in hospital (hospital acquired infection). Previous work done by this group has shown that by adding a drug called granulocyte macrophagecolony stimulating factor (GM-CSF) to a sample of blood from these patients in the lab, it is possible to restore the ability of the white blood cells to ingest bacteria and fight infection. This study will test whether it is possible to restore the capacity of patients' white blood cells to eat germs by giving them GM-CSF as an injection while they are on intensive care. The study will involve identifying adult patients on intensive care whose white blood cells don't work properly in this way. Patients taking part in the study will receive an injection, under the skin, of either the drug, GM-CSF, or a solution which will have no effect (placebo). The investigators will compare whether those patients who have received the GM-CSF injection have an improvement in the function of the white blood cells compared to those who don't. As well as looking at the function of the white blood cells the investigators will also study whether there is a difference in the rates of infection picked up in hospital between the two groups. This study is funded by the Medical Research Council.
Improving Communication About Serious Illness
Critical IllnessChronic Disease12 moreThe purpose of this study is to improve care delivered to patients with serious illness by enhancing communication among patients, families, and clinicians in the outpatient setting. We are testing a new way to help patients share their preferences for talking about end-of-life care with their clinicians and families. To do this we created a simple, short feedback form. The form is designed to help clinicians understand what patients would like to talk about. The goal of this research study is to show that using a feedback form is possible and can be helpful for patients and their families.
Sleep and Circadian Rhythms in Mechanically Ventilated Patients
Respiratory FailureCritical IllnessThis study examines the feasibility of assessing sleep and circadian rhythmicity in critically ill patients undergoing mechanical ventilation. Secondarily, it will examine the feasibility of reducing subject exposure to environmental light and noise and of delivering routine care according to classical day/night routines.
Daily Sedative Interruption in Critically Ill Patients Being Managed With a Sedation Protocol
Critical IllnessThe purpose of this study is to determine whether the use of both a nurse-driven sedation protocol and daily sedative interruption, compared with a sedation protocol alone, result in better outcomes for mechanically ventilated adults.
The Clinical Informationist: Does the Model Work
Critical IllnessThis study is investigating the effects of an established clinical informationist program (evidence-based practice support service in which information professionals with significant clinical knowledge bases and advanced information seeking and appraisal skills) on clinical decision making at selected critical care units at Vanderbilt University Medical Center
Assessment of Kidney Function for Drug Dosage Adjustments in Critically Ill Patients
ICU PatientsThe aim of the study is to determine if colistin dosage adjustment using 4hr CrCl contribute to better clinical outcomes compared with drug dosage adjustment using eGFR in critical ill patients. In control group, colistin maintenance dosage will be decided using serum creatinine based eGFR (in ml/min). In study group, colistin maintenance dosage will be decided using 4hr CrCl.
The Effectiveness of Hand Massage on the Pain of Cardiac Surgery Critically Ill
PainPostoperative pain is a common phenomenon in the intensive care unit (ICU) despite the multitude of efforts dedicated to promote its effective relief. Mounting evidence shows that cardiac surgery ICU patients experience moderate to severe pain reaching proportions as high as 74% despite the use of analgesics. The highest pain intensity is experienced in the first 24 hours post surgery when patients are still in the ICU, and represents a strong predictor for the presence and severity of persistent postoperative pain. To maximize pain relief, massage has been suggested in the recent clinical practice guidelines of the Society of Critical-Care Medicine as a complementary non-pharmacological therapy in the ICU given its opioid-sparing and analgesia-enhancing potential. Some randomized controlled trials showed promising pain relief effects of massage when administered to cardiac surgery patients in acute care units, however, its effects on pain relief while patients are still in the ICU and when pain severity is highest remain unknown. This study aims to compare the effect of three 20-minute hand massage administrations within 24 hours postop on the pain intensity (primary outcome), pain unpleasantness, pain interference, muscle tension, anxiety and vital signs (blood pressure, heart and respiratory rates) of adult intensive care unit (ICU) patients post cardiac surgery versus hand holding (i.e., simple touch) and standard care. Other objectives are to describe the location and quality of pain of cardiac surgery ICU patients. Hypothesis: Patients receiving 3 hand massages within 24 hours postop will have lower pain intensity, unpleasantness and interference, muscle tension, anxiety and vital signs compared to patients receiving hand holding and to those in the standard care group.
Mechanical Ventilation in Severe Brain Injury: The Effect of Positive End Expiratory Pressure on...
Intracranial HypertensionCritical Illness5 moreThe purpose of this study is to collect physiologic data from patients with severe brain injury who require mechanical ventilation in order to describe the impact of ventilation, specifically positive end expiratory pressure (PEEP), on intracranial pressure (ICP).
