Filter by:This trial aims to identify the effects of methylene blue infusion on the the micro-circulation in patients with septic shock. The investigators will evaluate various indices of micro-circulation such as: microvascular flow index, the flow heterogeneity index, the total vessel density, the perfused vessel density, and the proportion of perfused vessels.
Major deep burns (>20% body surface, involving deep skin layers) and associated severe inflammatory reaction and their complication are one of the biggest challenge of intensive care. Haemoadsorption therapy, including the CytoSorb treatment is a promising novel therapeutic approach, but only case-studies are available in the literature yet. Based on data from septic shock patient treatment the investigators hypothesize that CytoSorb is beneficial in early treatment of burns. The investigators aim to conduct a randomised-controlled study to assess the clinical effectiveness (based on score systems including MODS, SOFA, APACHE II, KDIGO, ABSI), 7 and 28 days survival, intensive care length of stay, length of mechanical ventilation, resuscitation fluid need and ino/vasopressor drug doses and the presence and severity of organ dysfunctions, particularly renal dysfunction. The investigatora plan to conduct basic research to elucidate the pathophysiological background of clinical effect, including the measurement of inflammatory and anti-inflammatory cytokines, presence and severity of oxidative stress (lipid peroxidation, protein oxidation, reduced/oxidised glutathion levels) and organ dysfunction markers (kidney injury molecule -1, neutrophil gelatinase-associated lipocalin, cystatin-C, uromodulin).
Background： The mean arterial pressure（ MAP） is a key pressure index to improve tissue perfusion. At present, there are no surprising results of large-scale clinical studies on sublingual microcirculation. The changes of sublingual microcirculation were more severe in septic shock non-survivors than survivors. Purpose： This study is mean to increase the MAP in septic shock patients whether with chronic hypertension or not, so as to observe the change of the microcirculation and prognosis. Method： This is a single-center, randomized, prospective cohort study. Eligible patients will be allocated into chronic hypertension or denying chronic hypertension group. These patients will be treat with vasopressors to maintain MAP at 90±5 mmHg and 70±5 mmHg. Outcome： The 28-day all-cause mortality, the 90-day all-cause mortality, the 28-day without organ dysfunction days, the Changes of sublingual microcirculation, SOFA， APACHE-Ⅱ score Will be recorded.
The objective of this project is to determine if in patients admitted to the hospital with septic shock (population), does treatment with a bundle including hydrocortisone, thiamine, and ascorbic acid improve in-hospital or 28-day mortality (primary outcomes) or surrogate markers of illness severity including: (1) ICU or hospital length-of-stay, (2) duration of invasive mechanical ventilation, (3) duration of vasopressor administration, (4) incidence and severity of ICU delirium, and (5) illness severity (secondary outcomes).
The aim of the study to examine Optic Nerve Sheath Diameter measurement for prediction of fluid responsiveness in hemodynamically unstable patients
Cardiogenic shock (CS) mortality remains high (40%). Despite their frequent use, few clinical outcome data are available to guide the initial selection of vasoactive drug therapies in patients with CS. Based on experts' opinions, the combination of norepinephrine-dobutamine is generally recommended as a first line strategy. Inotropic agents increase myocardial contractility, thereby increasing cardiac output. Dobutamine is commonly recommended to be the inotropic agent of choice and levosimendan is generally used following dobutamine failure. It may represent an ideal agent in cardiogenic shock, since it improves myocardial contractility without increasing cAMP or calcium concentration. At present, there are no convincing data to support a specific inotropic agent in patients with cardiogenic shock. Our hypothesis is that the early use of levosimendan, by enabling the discontinuation of dobutamine, would accelerate the resolution of signs of low cardiac output and facilitate myocardial recovery.
Sepsis is an acute pathology defined as an inappropriate response of the host to infection, resulting in the onset of organ failure (Quick SOFA ≥2, or SOFA ≥2). Septic shock is a sepsis associated with an elevation of lactate ≥ 2 mmol / l and an arterial hypotension requiring vasoactive drugs. Several studies highlighted that sepsis is associated with a plasma L-arginine deficiency. This deficiency induces a lower availability of L-arginine for multiple metabolic pathways including those involved in the synthesis of nitric oxide (NO) in the vascular endothelium via NO synthase. NO is the main endogenous vasodilator mediator, a lower synthesis induces a vascular and endothelial dysfunction that can promote the occurrence of an organic dysfunction during sepsis. Decrease in available NO was confirmed in patients with sepsis and appears correlated with severity. L-arginine deficiency can have multiple origins: - L-arginine deficiency resulting from a decrease in endogenous production from citrulline synthesized by the enterocytes. Such enterocyte dysfunction has been confirmed in patients with sepsis and is characterized biologically by elevated plasma levels of I-FABP (intestinal fatty acid binding protein - enterocyte-specific protein, cytolysis marker) and lower than that of citrulline (hypocitrullinemia, marker of lower activity). - L-arginine deficiency may also result from a catabolism increase via arginase activity increased. This ubiquitous enzyme, having 2 isoforms (Arg1 and Arg2), allows the synthesis of urea and ornithine from L-arginine. An increase in arginase activity would decrease the available reserves of L-arginine for NO synthesis. The objectives of this work is to evaluate, in patients with severe sepsis or septic shock, the prognostic value of the plasma arginase activity and the plasma expression of 2 isoforms Arg1 and Arg2, their kinetics, and the link between activity / expression of arginase and enterocyte dysfunction.
Recent studies have suggested that the use of left ventricular ejection volume index calculation may aid in the hemodynamic management of critically ill patients. However, a prospective and randomized comparison in patients with heart failure for inotropic dose adjustment has not been described. The objective of this study was to evaluate the efficacy and safety of ejection volume index versus liberal strategy in adjusting dobutamine dose in patients with heart failure and low cardiac output. Methodology: A unicentric, randomized and prospective study will be performed in a comparative manner. Hospital data (test results, medical outcomes, dobutamine dose, complications) of patients will be analyzed for safety and effectiveness. Expected results: The use of ejection volume index is not inferior to the liberal strategy in the initial adjustment of the dose of dobutamine in patients with heart failure.
Adults older than 18 years old, admitted to the ICU with a Severe Septic Shock, requiring Norepinephrine at more than 0.25mcg/kg/min, who have signed informed consent form, will be consecutively included, from december 2018 to december 2019. The primary goal is to look for risk factors associated with an increased in lactate clearance Secondary goals are the following: 1. To look for risk factors associated with an increase risk of Hospital and ICU length of stay. 2. To look for risk factors associated with an increase risk of Acute Kidney Injury. 3. To look for risk factors associated with a decrease in days alive and free of Mechanical Ventilation, Vasopressors and Renal Replacement Therapy. 4. To look for risk factors associated with a decrease in Ventilator-free days. 5. To look for risk factors associated with a decrease in Vasopressor-free days. 6. To look for risk factors associated with an increase risk of in-hospital mortality. 7. To look for risk factors associated with an increase risk of Myocardial Infarction and myocardial injury. 8. To look for risk factors associated with an increase risk of Acute Respiratory Distress Syndrome. 9. To compare and validate different risk scores in our cohort.
Recent in vivo studies from others as well as the investigators group demonstrated that volatile anesthetics immunomodulate sepsis and improve outcome. Also, several clinical trials have convincingly shown that application of a volatile anesthetic provides protection in patients undergoing major surgery. Patients with sepsis are intubated and ventilated and therefore need sedation. So far, most ICU centers use intravenously applied sedatives in these patients. In the proposed study, we will switch sedation from an intravenous to a volatile anesthetic for a short period of time to explore if sepsis markers improve within the following 120 hours upon sevoflurane conditioning.
