Filter by:The purpose of this study is to determine whether an additional physical therapy program can improve the mobility and functional outcomes of patients diagnosed with severe sepsis (an illness in which the body has a severe response to bacteria or other germs and develops worsened function of a major organ such as the kidneys, heart, or lungs).
Sepsis is the body's response to a life-threatening infection. This study will determine if zinc supplementation is safe to use in patients with severe sepsis or septic shock. This study will also gather preliminary information to evaluate the impact that zinc has on the immune system (the body's defense system against infection) and whether zinc can help monocytes and macrophages (specific types of cells that remove infections from the body) work more effectively.
Despite early goal-directed maintenance of normal macrocirculation, the reduction of 60-day mortality of patients with severe sepsis and septic shock remained unsatisfied (56.9% to 44.3%). One of the major causes of high mortality is microcirculatory dysfunction. Delayed diagnosis and treatment of microcirculatory dysfunction may cause tissue hypoperfusion and resulted in multiple organ dysfunction and death. Dexmedetomidine is a highly selective α2-adrenoreceptor agonist which exhibits sedative and analgesic effects. Recent studies suggest that dexmedetomidine also has anti-coagulation and anti-inflammatory effects, and it can reduce the mortality of endotoxemic rats and patients with severe sepsis. The investigators will conduct two animal studies and one clinical trial to investigate the effect of dexmedetomidine on microcirculatory dysfunction and organ injury in rat with endotoxemia and patients with severe sepsis and septic shock. Sixty patients with severe sepsis and septic shock will be enrolled and randomized to control group or dexmedetomidine group. In the control group, the patients will be treated according to the clinical practice guideline. If sedation is required, non-dexmedetomidine sedative agents will be used. In the dexmedetomidine group, the patients will be treated according to the clinical practice guideline, and they will also receive continuous infusion of dexmedetomidine (infusion rate ranged from 0.1 to 0.7 mcg/kg/h) for 24 hours as needed. The sublingual microcirculation, serum level of Endocan, NGAL(Neutrophil Gelatinase-Associated Lipocalin), and BNP(B-type natriuretic peptide) will be examined at preset time points up to 24 hours. The vital signs, hemodynamic parameters, and survival of 28-day and 90-day will be recorded and analyzed.
This is a randomized, open label study to evaluate the Initial Specimen Diversion Device (ISDD) in reducing the contamination rate in blood culture analysis. Blood culture data will be derived from inpatient and/or outpatient settings in a variety of hospital departments (e.g. ER, surgical, medical, etc.). Only samples that are collected via PIVC's may be included in this study. The ISDD will be compared to current laboratory practices for the collection of blood for culture purposes. Laboratory Standard Procedures (LSP) is defined as collection of venipuncture blood for culture without an initial diversion method to divert and sequester potential blood contaminants.
The primary objective of the proposed study will be to determine if a multi-modality teaching curriculum utilizing high-fidelity simulation and didactic lecture will result in sustained improvement by internal medicine residents in written knowledge and clinical performance when compared to residents receiving a curriculum utilizing only didactic lecture. The investigators hypothesis is that the addition of high-fidelity simulation to a traditional didactic lecture curriculum will result in sustained and superior written knowledge and practical performance when compared to a group receiving only didactic lecture on the same topic. Specifically, the investigators will be assessing internal medicine resident knowledge and performance in the area of sepsis in the hospitalized patient, and will shape the investigators teaching curriculum around this focus.
Endotoxin is the major mediator of gram-negative bacteria which cause the systemic inflammation and result in microcirculatory dysfunction, and it leads to multiple organ dysfunction and death in patients with severe sepsis and septic shock. The goal of this study is to measure the endotoxin activity of patients with severe sepsis and septic shock at certain time points, and furthermore, to compare the difference of endotoxin activity among different pathogens, infection source, and antibiotics. The study will enroll severe sepsis and septic shock patients. The endotoxin activity will be measured at certain time points according to the protocol.
Acute respiratory distress syndrome (ARDS) is a devastating form of acute lung inflammation, that may be caused by a variety of insults with pulmonary and systemic infectious disease being the most common predisposing factor. Sepsis, on the other hand, represents the systemic inflammatory response to an invading pathogen, which may inflict damage upon the host through organ dysfunction. ARDS and sepsis are heterogenous clinical conditions that have a high mortality, and both diseases involve a complex interplay of different inflammatory mediators and cell types. It has been suggested that locally released inflammatory mediators pass from the lungs into the bloodstream following ARDS, triggering systemic inflammation. Conversely, it is possible that severe systemic inflammation may lead to ARDS by an influx of inflammatory mediators from the bloodstream to the lungs. However, the time course and the possible pathways for this transmission of disease have yet to be established. Investigators hypothesize that: 1. Primary systemic inflammation is followed by a secondary pulmonary inflammatory response 2. Primary pulmonary inflammation is followed by a secondary systemic inflammatory response 3. Both primary and secondary inflammatory responses are characterized by the appearance of pro-inflammatory cytokines, inflammatory cells and production of collagen-like proteins (termed 'lectins') 4. The inflammatory response is most pronounced in the primary afflicted compartment.
Rationale : Electric muscle stimulation reduced critical-illness related weakness in patients with severe sepsis and septic shock. But optimal protocol of the stimulation in unknown. Hypothesis: Focal muscle contraction may improved the muscle power and have systemic anti-inflammatory via cytokine secretion . The difference of electricity used in upper limb or lower limb stimulation may lead to different effect. Study design: Stratified randomized parallel control study, comparing Biceps, Quadriceps electric muscle stimulation vs. non-stimulation group. Participant: adult patients with severe sepsis and acute respiratory failure requiring mechanical ventilation. Intervention: daily stimulation of bilateral Biceps or Quadriceps by programmed electric devices 32 minutes, 5 days/week Outcome: 1. Primary outcome: Ventilator-dependent days 2. Secondary outcome: change of hand drip muscle power/interleukin-1b/interleukin-6/interleukin-8/TNF-alpha
It is clearly shown that patients in the Intensive care Unit (ICU) with severe sepsis or multi organic failure are very susceptible to develop neuromuscular complications. That can be attributed to a hyper catabolic state, general inflammation and immobilization. This can leads a significant muscle wasting, polyneuropathy and/or myopathy. These alterations have been defined with the term Intensive Care Acquired Weakness (ICUAW) and can leads important functional squeals and impaired quality of life for months, years and in some cases irreversibly. To overcome these complications, early activation by physiotherapy becomes an important tool. This type of treatment has been show to be feasible, safe and improves the functional capacity of patients. In addition to a reduction in the duration of ICU and hospital stay and improved quality of life for patients. The objective of this study is to demonstrate that the early and active physical activity in patients with severe sepsis can limit the loss of muscle mass and complications related to this type of damage. Procedures: Patients or relatives will be asked to participate in the study. If a positive response is done, patients will be randomized in an intervention or control group. A baseline evaluation will be performed during the first day of study admission. That includes a physical exploration, electrophysiological studies, skeletal muscle histological/biochemical evaluations and monitoring of blood biomarkers and others clinical outcomes will be registered. Intervention will be divided in a morning and afternoon times, patient will be positioned in chair or bed and mobilized by physiotherapist. As usual, all patients will be attaining manual mobilization for 20 minutes twice a day. Only for intervention group, additional cycle-ergometer exercise will be performed for 30 minutes at better performance achieved and tolerated for patient. All vitals parameters will be strictly controlled before, during and after intervention. The same baseline evaluation will be repeated after day 7 and clinical outcomes will be registered until ICU discharge.
This Randomized, pragmatic, multicentric with blinding of patients and health professionals, intention-to-treat analysis has by primary endpoint to evaluate whether the aspirin use reduces the intensity of organic dysfunction measured by the variation of the SOFA score starting from the day of admission to the seventh day. Secundary endpoint: To evaluate if the aspirin use reduces the time of mechanical ventilation, length of stay in the ICU and in the hospital. In addition, to evaluate the safety of its administration regarding the occurrence of bleeding. The data will be collected directly from the chart of the patients admitted to the ICU. Data quality assurance will be made through periodic verification, aiming for complete and consistent data. The centers will receive periodic reports for adequacy of potentially inconsistent or incomplete data. The baseline SOFA of patients with sepsis is 8.8 with a standard deviation of 3. The expected reduction in the control group in the SOFA at day 7 is 2 points. Considering a power of 80% and a level of significance of 0.05, it is estimated that 109 patients will be needed in each group. A total of 218 patients will compose the sample. All analyzes will follow the intention-to-treat principle. We will evaluate the effect of aspirin compared to placebo on primary and binary outcomes by means of relative risks, 95% confidence intervals and chi-square tests. For continuous outcomes with normal distribution, we will present the mean difference, 95% confidence interval and P value calculated by t test. For continuous outcomes with asymmetric distribution, we will perform Wilcoxon test.
