Evaluation of Impaired Microcirculation During Septic Shock With Contrast Enhanced Ultrasound
SepsisMicrocirculatory disorders play a central role in the pathogenesis of sepsis and septic shock. Without adequate therapy that may lead to multi-organ failure and death. Therefore useful therapeutic measures aim to improve the microcirculation, to avoid tissue hypoxia and thus multiple organ failure or death. Clinically, the microcirculation can currently be indirectly evaluated using the diuresis and metabolic parameters (eg, lactate). The aim of the present study is to measure the microcirculation in septic shock by means of contrast-enhanced sonography of the calf muscles. For this purpose, the method is applied to 24 subjects during and after septic shock. It will be investigated in this study whether the microcirculation measurement with ultrasound contrast reflects the severity of the disease. As well as to evaluate whether the use of this diagnostic method could lead to better treatment of the septic shock.
Hemodynamic Optimisation Guided With Transcranial Doppler in Septic Shock
Trans Cranial Doppler Ultrasonography in Heamodynamic Optimisation in Septic ShockRandomized, controlled, prospective trial, including ICU patients with Sepsis or septic Shock, at the early phase. patients will be randomized in 2 groups regarding the hemodynamic management and catecholamin doses: Group 1: standard hemodynamic goals and catecholamin infusion to achieve: mean arterial pressure > or equal to 65 mmHg and diastolic arterial pressure > ou equal to 50 mmHg within the first 60 minutes. Group 2: personalized hemodynamic goals and catecholamin infusion until normal transcranial doppler: IP<1,2.
Correlation of VEGF-A and Fluid Balance in Septic Shock
Septic ShockVEGF is a key molecule in the control of vascular permeability via interactions with the VEGF-receptor on the endothelial cell. Several authors reported plasma VEGF levels are elevated in sepsis shock and associated with increased mortality (1,2). In septic shock, the main elements of treatment are intravenous fluids, appropriate antibiotics and vasopressors. Some authors observed positive fluid balance is associated with increased mortality rates in patients (3,4). To the best of our knowledge, no studies have shown a correlation between VEGF levels and the fluid balance. The aim of our study was to determine the role of VEGF in capillary leakage and the positive fluid balance in septic shock.
The Pharmacokinetics/Pharmacodynamics of High-dose Daptomycin in Patients With Septic Shock
Septic ShockThe first objective of this study was to characterize the pharmacokinetics and pharmacodynamics of daptomycin with a daily dose of 12mg/kg in septic shock patient; the second objective is to identify the optimal dosing scheme for daptomycin among patients with septic shock and to enhance therapeutic outcomes.
Long-term Cognitive and Cerebral Changes in Sepsis Survivors and Their Predictors
Severe Sepsis With Septic ShockSevere Sepsis Without Septic ShockThe main goals of this study are to provide a cognitive, neurological, brain morphological, and serological profile of sepsis survivors in order to make long-term prognosis of recovery and estimate the need for rehabilitation measures in order to help patients reintegrate into normal daily life.
Thiamine, Vitamin C and Hydrocortisone in the Treatment of Septic Shock
Septic ShockThe purpose of this research study is to determine whether patients who receive thiamine (vitamin B1), vitamin C and hydrocortisone while in septic shock have improved outcomes compared to hydrocortisone alone. A recently published article "Hydrocortisone, Vitamin C and Thiamine for the treatment of Severe Sepsis and Septic Shock," suggested substantial mortality reduction (78%). We wish to test the hypothesis that mortality reduction is at least 25% in a prospective randomized trial. Other important sub-aims include the testing whether the protocol reduces the time on pressors agents, reduces the trajectory of the SOFA score, or reduces the trajectory of procalcitonin.
Observational Study on Intubation in Septic Shock
Septic ShockSeptic shock is common in intensive care and its mortality remains high. While new treatments have not improved survival, optimization of known and widely used techniques has allowed reduction in mortality. Thus improving care given to patients starts with making better use of existing resuscitation techniques. Among these practices, mechanical ventilation is widespread in the management of patients with septic shock. In large studies published in recent years in Europe and North America, 40 to 85% of patients receive invasive mechanical ventilation. It therefore appears that a significant proportion of patients are never intubated during treatment and management of their septic shock. There is no specific recommendation from critical care societies concerning mechanical ventilation in the treatment of septic shock. Apart from indisputable situations such as impaired consciousness or acute respiratoire distress, the decision whether to ventilate mechanically or not is left to the discretion of the physician. The aim of this study is to analyze intubation practice in septic shock patients and its impact on 28-day survival. This multicentric and observational study will be conducted in 30 French ICUs.
Effects of Dexmedetomidine vs Midazolam on Microcirculation in Septic Shock Patients
Septic ShockTo investigate changes in the concentration of glucose, lactate, pyruvate and glycerol in the extracellular fluid of the skeletal muscle following Dexmedetomidine administration in patients with septic shock.
Cirrhotic Patients With Septic Shock
Septic ShockCirrhosisCirrhotic patients have a poor outcome in intensive care unit (ICU). Septic shock is a leading cause of ICU admission and death in this specific population. We performed a monocentric retrospective study; all cirrhotic patients admitted in the ICU with septic shock from 2002 to 2013 were included. The aim of the study was to identify prognostic factors for both short- and long-term mortality in these patients. Demographic, clinical and biological data, organ supports, and outcomes were collected. Univariate and multivariate analysis were carried out regarding both ICU and one-year mortality.
Validation of Uncalibrated Cardiac Output Measurement With LiDCOrapid in the Resuscitation of Critically...
Cardiac OutputLIDCO Rapid1 moreTransthoracic echocardiography (TTE) has been used as a reference technique for CO measurement and its accuracy has been adequate for many clinical uses. TTE is painless, safe and non-invasive. Some drawbacks of TTE are being expensive, bulky and needs advanced training. Currently, due to increased interest in minimally invasive hemodynamic monitoring, multiple new methods have become commercially available to assess CO: the arterial pulse aortic flow, bioreactance, and bioimpedance. One of these new devices is LiDCOrapid (LiDCO Ltd, Cambridge, UK). It is a new, minimally invasive monitor which estimates beat-by-beat CO and fluid responsiveness from the arterial waveform. It has been validated after vascular, urological and thoracic surgery and shows good agreement with the PA catheter in swine, in patients with normal left ventricular systolic function and in patients with vasodilatation. However, LiDCO has not yet been validated in patients with septic shock. Therefore, the aim of this study is to validate LiDCOrapid parameters in septic shock patients using TTE derived parameters as the non-invasive reference.
