Filter by:Sepsis induces hemostatic disorders due to the exessive or inappropriate activation of inflammation, which could lead either to hypercoagulability or hypocoagulability. It is currently not possible to determine the hemostatic status of a given patient. This instability of hemostatic system is not revealed by classical tests. Thus, a better characterization of hemostatic status could certainly improve patient care. This study aims at characterizing disorders of coagulation and fibrinolysis using "global" tests such as thrombin generation test or coagulolytic test. Furthermore, the association with biological markers of interest (such as microparticles, neutrophil elastase or histones) will be evaluated.
The aim of this study is to assess the causes of death in patients with septic shock in French intensive care units. It is an epidemiologic and descriptive study .
Using sodium lactate Ringer's injection resuscitate septic shock patients and Compared with other solution, in order to make clear whether can improve the prognosis.
Patients with septic shock may have altered volume of distribution and metabolism of antibiotics which are crucial medications for treating infections. The aim of the study is to investigate the blood concentrations of Meropenem and Ciprofloxacin, two commonly used antibiotics, in patients with septic shock. The hypothesis is that standard dosing may produce insufficient levels of antibiotics in patients with septic shock.
Fluid challenge is often carried out in critical ill patients. Its responsiveness usually requires invasive monitoring. To use non-invasive methods is very tempting. We hypothesize that transcutaneous pO2,transcutaneous pCO2 and Central Venous pO2 variations provide feasible estimation on fluid responsiveness in critical ill patients.
Reducing tissue hypoxia is the ultimate goal of severe sepsis and septic shock therapy.Venoarterial PCO2 difference /arteriovenous O2 content difference ratio (△PCO2/Ca-vO2) is considered to be a good indicator of global anaerobic metabolism.The purpose of this study was to compare the efficacy of △PCO2/Ca-vO2 and central venous oxygen saturation (ScvO2) in the treatment of severe sepsis and septic shock.
OBJECTIVES. To establish the therapeutic efficiency of melatonin in adult patients with severe sepsis and septic shock. Specifically: 1. To evaluate the survival to 28 days of mechanical assisted ventilation, days with vasoactive drugs, need of hemodialysis-hemofiltration, superinfection and evolution towards the failure of other organs. 2. To evaluate, waiting for reduction under the influence of the treatment with melatonin, : 1. clinical - analytical parameters of sepsis; 2. levels of cytokines; 3. oxidative and nitrosative stress; 4. acute-phase proteins (APP), specially of the ITIH4; 5. immune response; 6. endocrine response. METHODOLOGY. Patients will be randomized in two groups, n = 55 in each group: 1) treatment with melatonin 30mg/12 hours 28 days; 2) placebo. Determinations: a) clinical - analytical parameters relative to the sepsis; b) melatonin plasmatic levels; c) quantification of malonyldialdehyde and 4-hydroxynonenal, protein carbonyl content, nitrites, erythrocyte membrane fluidity, and superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase activity; d) Interleukins-1,2,4,5, 6, 7,8,10,12,13, IFN-γ; TNF-α and GM-CSF; e) acute-phase proteins: PCR, haptoglobin, Apo A-I, α1-GPA and ITIH4; f) lymphocytes T, B, NK, T CD4, and T CD8, and immunoglobulins; g) cortisol, aldosterone, ACTH, ADH, insulin, glucagon and 25-hydroxyvitamin D3. Data will be analyzed following a prospectively define plan and by intention-to-treat (ITT) analysis.
HW6 can prolong animal's survival time and increase the survival rate. HW6 enhances cardiac function, improves microcirculation, and increases blood pressure and pulse pressure, and improves blood perfusion of important organs; HW6's anti-shock activity comes from a combined multiple target pharmacological effects. Based on a completed phase II trial conducted in China, HW6 can effectively treatment shock patient. This is a phase II clinical study to further evaluate the efficacy and safety of Polydatin Injectable 100mg/5mL/via (HW6) in the treatment of shock in the United States. Patients with traumatic/hemorrhagic shock or septic shock admitted to the emergency room or ICU with systolic blood pressure < 90mmHg, or is on vasopressor(s) for systolic blood pressure stabilization, regardless the types of completed, on-going, or projected Standard of Care or surgery will be recruited to participant in the trial. A total of 120 patients with traumatic/hemorrhagic shock and 120 patients with septic shock will be enrolled. For each type of shock, sixty patients each will be in test group and control group. Both adult males and females aged 18-80 years are eligible. The primary clinical endpoint is the time length (TL) between the start of HW6 administration to the onset of the first treatment success, that is: the systolic blood pressure is stabilized at ≥90mmHg and MAP≥65mmHg for 1 hour without the use of vasopressors. Several secondary endpoints and biomarkers will be measured. Efficacy data will be compared using group t-test or Wilcoxon log-rank test between treatment groups and placebo groups. Safety data will also be reported accordingly.
Recurrent ICD shocks are a serious problem in pts with ICD. Treatment failure with other antiarrhythmics and ablation are common. Dronedarone is a new antiarrhythmic drug with ion channel properties similar to amiodarone. Several case reports have shown promising results with Dronedarone for this patient population.
Fluid therapy is an important part of the management of patients with hemodynamic instability in the intensive care unit. By increasing cardiac preload, it aims at elevating cardiac output (CO) and thus restoring hemodynamic conditions in patients who are preload responsive. By contrast, volume administration can be deleterious in terms of pulmonary edema formation or other manifestations or fluid overload, especially in patients who are not preload responsive. Functional dynamic parameters that use heart-lung interactions, such as pulse pressure variation (PPV) and stroke volume variation (SVV) are considered accurate predictors of preload responsiveness in patients receiving fully controlled mechanical ventilation. However, in cases of spontaneous breathing activity where heart-lung interaction indices fail to predict fluid responsiveness, one needs parameters able to reliably predict the hemodynamic response of fluid administration. A new index that could indicate fluid responsiveness, so-called the fluid responsiveness index (FRI), has been elaborated. The advantage is that it could be used in patients who are not in control mechanical ventilation as well as in patients who are fully adapted to mechanical ventilation. The FRI is based upon the analysis of continuous arterial and continuous central venous pressure. The FRI is determined by the relation of cardiac and respiratory activity; both are evaluated by means of power spectrum analysis of the pressures recorded. The aim of this study is to test the value of the FRI to predict the hemodynamic response to fluid infusion in patients with hemodynamic instability not receiving fully controlled mechanical ventilation.
