Filter by:There is a knowledge gap regarding the optimal initial fluid to achieve effective resuscitation and improved outcomes in septic shock. The purpose of this study is to compare initial resuscitation with plasma to initial resuscitation with balanced crystalloids.
Unwell patients in the intensive care unit (ICU) often need supplementary fluids to be given into the bloodstream through a drip in a vein (venous cannula), however too much fluid can be harmful. It can sometimes be difficult to tell whether or not a patient will benefit from extra fluids so they are given a "fluid challenge", whereby a small volume of fluid is given quickly into the cannula and the change in their status is noted. If the patient's condition improves, this suggests that the patient is "fluid responsive" and needs more fluid. A LiDCOplus haemodynamic monitor is a device used in the ICU to estimate the amount of blood ejected from the heart on each heartbeat using pressure readings obtained from a tube placed in one of the patient's arteries (arterial line). The investigators aim to determine whether or not the use of this device called makes a difference to the judgement of "fluid responsiveness" when the patient is given a fluid challenge when compared to simply using measurements of pulse and blood pressure and assessing the circulation in the patient's limbs. This will allow the investigators to determine whether or not the LiDCOplus alters the decisions made by doctors and nurses about how much fluid to give their patients and hence if it is of any benefit.
Sepsis and septic shock patients are considered to have a high risk of complications and death. Appropriate antimicrobial therapy plays an important role in determining outcomes in septic patients. However, pathophysiologic changes associated with critical illness have an impact on pharmacokinetics of antimicrobials. In addition, increasing bacterial resistance is also a growing concern, especially in intensive care units., Consequently, standard antimicrobial dose may not be sufficient to achieve pharmacokinetic/pharmacodynamic target in sepsis and septic shock patients. The purpose of this study is to compare a therapy between meropenem standard dose and meropenem high dose in the treatment of sepsis and septic shock
Consecutive patients with ACLF (Acute on Chronic Liver Failure) and septic shock with AKI (Acute Kidney Injury) who give written informed consent will be included in this prospective trial at ILBS. At baseline s, endotoxin levels, NT-Pro BNP, , urine N-GAL will be done for all patients. A 10 ml serum sample will be stored for doing a cytokine profile. Septic shock will be defined by the presence of two or more diagnostic criteria for the systemic inflammatory response syndrome, proven or suspected infection with hypotension non-responsive to adequate fluid resuscitation assessed by no evidence of stroke volume variation on flow track and need of a vasopressor to achieve a target mean arterial pressure (MAP) of ≥ 65 mm Hg. A record of CVP, IVC diameter and B-lines on ultrasound lung would also be done. Patients with age less than 18 years, severe known cardiopulmonary disease (structural or valvular heart disease, coronary artery disease, COPD) pregnancy, chronic kidney disease, patients already meeting emergency criteria for immediate hemodialysis at the time of randomization as specified in the late group, patients transferred from other hospitals who have already been on hemodialysis before their arrival in the intensive care unit, extremely moribund patients with an expected life expectancy of less than 24 hours, failure to give informed consent from family members.
Cardiogenic shock is a frequent cause of admission and death in the intensive care unit. Mortality is about 50%. Once the etiologic treatment has been done, for instance coronary revascularization, management of the shock state is the cornerstone of the treatment. Norepinephrine is the first-line vasopressor therapy because of its minor effect on heart rhythm. Morever norepinephrine is a inotrope. In a previous study, we demonstrated that increasing the norepinephrine dose increases cardiac index, cardiac power index, SVO2 and tissue perfusion without acceleration of heart rate. Nevertheless, dobutamine remains the first-line inotropic treatment. Dobutamine has a positive chronotropic effect that might cause higher myocardial oxygen consumption. As a result, combination of vasopressor / inotrope is still controversial. The aim of this study was to compare hemodynamics and metabolics effects of 2 treatments strategies (norepinephrine dose increasing or addition of dobutamine) in patients with cardiogenic shock and optimised blood pressure level (MAP≥65 mmHg) under norepinephrine treatment. The secondary objectives were : - To evaluate the efficacy of the treatments on micro- and macrocirculation parameters - To evaluate the tolerance of the treatments - To evaluate the dose and the admistration's kinetics of the treatments
This is a randomized, double-blind, placebo-controlled clinical trial to compare Vitamin C versus placebo for patients presenting to the ICU with a diagnosis of septic shock.
In guidelines norepinephrine is the first line vasopressor recommended in case of septic shock. Use of vasopressin is recommended when norepinephrine fails to maintain a mean arterial pressure above 65mmHg or in salvage. Several studies failed to show a superiority of vasopressin over norepinephrine but none evaluated the effect of an early association on organ failure. Terlipressin is a pro-drug of vasopressin which has the same vasoconstrictor effect. We hypothesize that the early association of terlipressin and norepinephrine during septic shock reduces organ failure. This bi centric, double-blinded, randomised, controlled versus placebo study includes 40 patients. Randomisation will be stratified between centers (two university affiliated intensive care units of Assistance-Publique-Hôpitaux de Marseille, Marseille, France). All patients with septic shock needing more than 0,5µg/kg/min of norepinephrine to reach PAM objectives are randomised, after hemodynamic evaluation and optimisation, to receive continuous infusions of terlipressin (0,01mg/kg/min) or placebo (physiologic serum). The 2 groups receive steroid therapy (continuous intravenous hydrocortisone perfusion) at this time. Clinicians are blinded of perfusion used. Use of terlipressin remains possible in salvage when patients need more of 1µg/kg/min of norepinephrine on physician's decision. Patients with acute ischemic or septic heart failure are excluded of the study. Primary objective is sepsis related Sequential Organ Failure Assessment (SOFA) score difference between the groups at day 3. Secondary objectives are mortality at day 28, lactates clearance in the first 48hours, renal function (evaluates with AKIN criteria) and use of renal replacement therapy.
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.
Sepsis has been characterised as a dysregulated host response to infection. Adjunctive therapies targeting the inflammatory cascade are being increasingly explored, although to date, have failed to demonstrate consistent benefit, and sepsis continues to manifest poor outcomes. Hospital mortality in patients with septic shock remains as high as 22% in Australia and New Zealand. From a global perspective, 31 million sepsis and 19 million severe sepsis cases are expected to be treated in hospitals all over the world per year. To date, experimental data have reported that both high dose intravenous vitamin C and corticosteroids attenuate the acceleration of the inflammatory cascade and possibly reduce the endothelial injury characteristic of sepsis, enhance the release of endogenous catecholamines and improve vasopressor responsiveness. Therefore, the investigators plan to conduct a feasibility pilot prospective, multi-centre, randomised, open-label, trial in ICU patients with septic shock to test whether the intravenous administration of high dose Vitamin C (6g/d), Thiamine (400mg/d) and Hydrocortisone (200mg/d) leads to a more rapid resolution shock and vasopressor dependence.
Refractory cardiogenic shock is characterized by a decreased in cardiac output with hypo-responsiveness to increasing doses of catecholamines resulting in a profound tissular ischemia. VAECMO, by restoring a circulatory flow, could be associated to a major reperfusion syndrome which may lead some patients to multiple organ failures and death. Pathophysiology of this syndrome includes 1/an hyper-adrenergic state secondary to the over activation of the sympathetic system and 2/ a major release of pro-inflammatory cytokines. As adrenoreceptors are also exhibited on immunes cells, the pro-inflammatory state might be enhanced by the over-activation of the sympathetic system.
