Active clinical trials for "Shock, Septic"

Infections in critically ill patients are a major healthcare problem and an important source of morbidity and mortality. Since critically ill patients often have altered pharmacokinetics (PK) compared to non-critically ill patients there is a substantial risk that present standard dosing regimens of antibiotics lead to suboptimal outcomes for patients on the ICU or the ED. To prevent the risk of inadequate dosing in ICU patients, it is important to fully understand the PK of antibiotics in this vulnerable group in order to optimize the dosing regimens. With this study, the investigators will describe the pharmacokinetics of cefuroxime and amikacin in ICU and ED patients. A heterogeneous population of ICU and ED patients will be included to be able to find which factors might influence the pharmacokinetics of these drugs and to what extent. By using population modeling the investigators will simulate different dosing regimens and MIC values and compare probability of target attainment between each of these dose and MIC combinations. This will allow the investigators to optimize dosing regimens of cefuroxime and amikacin in critically ill patients.

Pneumonia is a common infectious disease of the lung, often requiring treatment in the hospital. Clinical scoring systems are available, identifying patients not requiring hospitalization. However, the course of disease of patients in the hospital remains hard to predict. While most patients will recover quickly, some will, despite appropriate treatment, develop a severe course leading to sepsis and systemic responses resulting in organ dysfunction. The PROGRESS consortium aims to identify clinical, genetic, and other molecular markers and combinations there of predicting a severe course of pneumonia in the hospital. Such predictors will, for instance, support decisions on earlier transfer of patients to intensive care and thus improving outcome. PROGRESS-COMORB aims to extend findings from the previous PROGRESS study to patients with more severe preexisting conditions and immunosuppression.

This is an observational study to understand the changes in alveolar dead space in medical critically ill patients with severe infection (severe sepsis) requiring mechanical ventilation and the possibility to predict multi-organ failure. The measurement of alveolar dead space used to require sophisticated equipment and time. New ventilators have microprocessors that allow rapid mathematical calculation with minimal intervention.

Fluid management is one of the key issues in the initial management of septic shock (SS). Fluid overload and hypovolemia have been associated with increased mortality in several trials. Transthoracic echocardiography (TTE) and lung ultrasound are recommended for haemodynamic assessment in critically ill patients. However, the benefit of hemodynamic optimisation using echography has not been yet evaluated. The purpose of this multicenter, controlled, randomized trial is to assess the impact of an echocardiographic algorithm of hemodynamic optimization on fluid management in septic patients during the first 4 days of therapy.

Ketamine is a commonly used drug for sedation and induction of anesthesia in patients with shock and/or cardiac dysfunction. Ketamine is characterized by its cardiovascular stimulatory effect due to increase release of endogenous catecholamines. On the other hand, laboratory data on the isolated human myofibers suggest that ketamine had a direct myocardial depressive effect; accordingly, many experts believe that ketamine might have a negative hemodynamic effect in catecholamine depleted patients such as critically ill patients. In critically ill patients, there are contradicting results for the effect of ketamine on the hemodynamic profile and there is paucity of clinical data about the effect of ketamine on cardiac contractility and cardiac output (CO). Cardiac output is the primary determinant of global oxygen delivery to organs and maintaining stable CO in critically ill patients is at most importance to avoid further organ damage in such patients. Therefore, this study is designed to evaluate the effect a single bolus of ketamine on CO in patients with septic shock in comparison to fentanyl bolus.

Over-resuscitation including fluid overload has been associated with increased morbidity (prolonged duration of organ failure) and mortality in septic shock. "One-size-fits-all" resuscitation strategies may increase septic shock mortality. However, clinical studies on individualized resuscitation are lacking. Hemodynamic phenotyping may allow to individualize septic shock resuscitation. The ANDROMEDA-SHOCK trial found that a simple clinical and bedside CRT-targeted resuscitation reduces organ dysfunction and 28-day mortality in septic shock. The current study will examine the hypothesis that a CRT-targeted resuscitation based on hemodynamic phenotyping considering within an decision tree usual bedside clinical parameters such as pulse pressure, diastolic blood pressure, fluid responsiveness and cardiac performance can further decrease mortality in septic shock as compared to usual care.

This project will evaluate the usefulness of Monocyte Distribution Width (MDW) for the diagnosis of blood culture positivity (BSI) in patients in the Emergency Department (ED) and reevaluate the usefulness of MDW in patients with BSI and sepsis. Consequently, if MDW indicate a high likelihood of bacteremia antibiotic management in patients with suspected bacterial infections will be changed and aid appropriate antibiotic administration.

The primary objective of this clinical investigation is to investigate the feasibility and possible benefits of the Alteco® LPS Adsorber in treating patients with septic shock with presumed endotoxemia of abdominal or urogenital origin.

The main purpose of this study is to determine the effects of controlling the heart rate of patients with septic shock using an intravenous medication called esmolol.

The global burden of sepsis is substantial with an estimated 15 to 19 million cases per year; the vast majority of these cases occur in low income countries. New therapeutic approaches to sepsis are desperately required; considering the global burden of sepsis these interventions should be effective, cheap, safe and readily available. The aim is to study the synergistic effect of vitamin C, hydrocortisone and thiamine on survival in patients with severe sepsis and septic shock.
