Unnecessary and prolonged antibiotic therapy in newborn babies can have serious consequences including development of necrotizing enterocolitis (a serious, potentially life-threatening gastrointestinal illness in premature babies), late-onset infections, resistance to antibiotics, increased length of hospital stay, and death. Starting and continuing antibiotic therapy for blood culture-negative infections in the neonatal intensive care unit (NICU) is fairly common with numbers of such patients varying from 20%-90% of infants undergoing a sepsis evaluation in the NICU. While blood culture results are the gold standard, there is usually a delay of up to 48-72h before the results are known. Hence, initiation and continuation of antibiotic treatment are usually based on clinical evaluation and blood count criteria which do not possess high specificity or sensitivity, and may be unreliable in the first few hours after birth or in the early stages of infection. Since the investigators found that neutrophil CD64 (a type of protein found on the surface of a type of white blood cell that can be detected quickly in a very small amount of blood sample) has high accuracy for early detection of blood culture-proven infections in newborn babies, with extremely high negative predictive value (can identify babies definitively with no infection), the investigators will use this test to decide whether to stop or continue antibiotics in the NICU. The investigators hypothesis is that neutrophil CD64 values can be safely used to discontinue antibiotics in newborns suspected of having infections. The investigators aims are to utilize sequential measurements of CD64 values to stop antibiotics early in neonates being investigated for both early and late-onset infections in the NICU. This is a prospective, randomized, controlled (RCT) trial. The study population will be derived from the sub-set of all newborn infants who have undergone investigations for presence of infection in the NICU.
Sepsis is widespread (1.8 million cases annually worldwide) and accounts for a very high mortality: 20-25% of all severe sepsis, 40-70% of all septic shock. The Surviving Sepsis Campaign (SSC) recommends a first 6 hours "resuscitative bundle" to improve patient's outcome. Despite this, the bundle is poorly performed, because of a superficial knowledge of the guidelines and several difficulties in their clinical implementation. In recognition of this, a "sepsis six" bundle is designed to facilitate early intervention with just three diagnostic and three therapeutic steps to be delivered by staff within 1 h. The aim of our study is to evaluate if an Educational and Organizational Intervention (EOI) could improve septic patient's outcome in no Critical Care Units. The second endpoint is to evaluate if the compliance to the "sepsis six" bundle could improve after this sort of intervention.
This study is to see whether the intravenous administration of methylene blue improves the outcome in severe sepsis and septic shock.
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.
Background: Dexmedetomidine, a highly selective arfa2-adrenergic agonist, is known to be a unique sedative agent which causes less acute tolerance, drug addiction and withdrawal compared with gamma-aminobutyrate (GABA) agonists. Dexmedetomidine was approved for short-term ICU sedation in 2004 in Japan, and it has been used particularly for surgical ICU patients. In August 2010 dexmedetomidine was approved in Japan for sedation lasting more than 24 hours. Recent evidence demonstrated that dexmedetomidine has organ protective effects including neuroprotection, cardioprotection, renal protection, gastrointestinal tract action, and anti-inflammatory action. Dexmedetomidine was shown to significantly decrease the infarct size in isolated rat hearts. Additionally, dexmedetomidine exhibited a preconditioning effect against ischemic injury in hippocampal slices, and this result was considered an apoptosis suppression effect of dexmedetomidine. Aydin C et al reported that dexmedetomidine enhanced the spontaneous contractions of the ileum in peritonitis rats compared with propofol and midazolam. Taniguchi and colleagues demonstrated that dexmedetomidine reduced high mortality rates and the plasma cytokine concentrations, interleukin-6 and tumor necrosis factor alpha in endotoxemic rats. A meta-analysis has shown that perioperative alfa2-adrenergic agonists, including dexmedetomidine infusion, decreased cardiovascular events on patients undergoing cardiac surgery. Dexmedetomidine treated patients undergoing thoracotomy indicated increase in urine output, reduction in serum creatinine, and the suppression of diuretics in a randomized placebo-controlled double-blind study. Septic patients receiving dexmedetomidine had improved 28-day mortality rates compared with septic patients receiving lorazepam in a sub-group analysis of MENDS randomized controlled trial. These positive effects of dexmedetomidine on the cardiovascular system, neurons, kidneys, gastrointestinal tract action, and an anti-inflammatory action, are expected to improve mortality in septic patients. However, large clinical research studies have not been conducted yet. We designed and conducted the DESIRE trial (DExmedetomidine for Sepsis in ICU Randomized Evaluation trial) to test a hypothesis that dexmedetomidine may improve clinical outcome and has these organ protective effects on septic patients. Objective: To determine whether dexmedetomidine improves clinical outcome and has organ protective effects on septic patients.
Cell-free hemoglobin can be measured in the plasma of patients with sickle cell anemia, hemodialysis, after red blood cell transfusion, and in patients with sepsis. Cell-free hemoglobin in these patient population has been associated with poor outcomes, including an association with an increased risk of death. Acetaminophen may have a protective effect in these patient populations by inhibiting hemoprotein-mediated lipid peroxidation. The purpose of the present trial is to study the effect of acetaminophen on lipid peroxidation in adults with severe sepsis and detectable cell-free hemoglobin. The primary hypothesis is that systemic markers of oxidative stress and lipid peroxidation, as measured by F2-isoprostanes, will be significantly lower in patients with severe sepsis and detectable cell-free hemoglobin who receive acetaminophen compared to placebo. The secondary hypothesis is that patients with severe sepsis and detectable cell-free hemoglobin treated with acetaminophen will have better clinical outcomes, including decreased incidence of acute kidney injury and lower rates of hospital mortality, compared to those who receive placebo.
Thousands of children die from Sepsis following routine infections. Many of these deaths can be prevented with earlier recognition and focused management. No tools are currently available to recognize the signs of early sepsis in children. The investigators have developed a electronic health record-based tool that will recognize children with sepsis early and trigger an alert to their hospital caregivers. The caregivers will be prompted to launch a focused management bundle that can stabilize these children, prevent further deterioration and reduce their chances of sepsis related complications and death. The proposed study will test the validity and effectiveness of this electronic tool in reducing sepsis mortality rates.
This study is being done to help determine whether patients with severe sepsis (overwhelming inflammation in the body as a result of an infection) lose muscle and become weak more rapidly than patients with other severe illnesses. Weakness and muscle loss that develops after a severe illness is a serious problem. Patients who develop weakness and have a decrease in muscle size often have to stay in the hospital longer and have a higher chance of dying. At the current time, it is not clear whether certain severe illnesses are more likely to cause weakness and muscle loss. This study will be done to measure the changes in muscle size and strength as a result of each patient's illness
