Filter by:The hallmarks of septic shock are hypovolemia and reduced pressor response to endogenous noradrenaline. The working hypothesis is that the higher the plasma concentration of endogenous noradrenaline will be, the lower the pressor response to exogenous noradrenaline will be. This will be tested in patients presenting with septic shock, following state of the art management (including repeated assessment of vena cava diameter and compliance, and response to dynamic indices of loading) following placebo vs clonidine administration (1 mcg.kg-1.h-1 over 24 h without bolus) and administration of increasing doses of noradrenaline (1 mcg, 2 mcg, etc. up to a delta systolic blood pressure circa 25-30 mm Hg).
Septic shock remains a significant clinical problem associated with high rates of mortality among neutropenic patient despite antimicrobial therapy and supportive care. Recently, mesenchymal stromal cells (MSC) have demonstrated remarkable potential effect in sepsis. MSC treatment significantly reduced mortality in septic mice receiving appropriate antimicrobial therapy. MSCs reduced systemic inflammatory cytokine levels in mice, down-regulated of inflammation and inflammation-related genes (such as interleukin-10, interleukin-6). Bacterial clearance was greater in MSC-treated mice. Thus, MSCs have beneficial effects on experimental sepsis and suggest that MSСs-therapy may be an effective adjunctive treatment to reduce sepsis-related mortality. The safety of MSCs is proved by Graft-versus-host disease treatment MSCs in patients after bone marrow transplantation. This study hypothesis is that MSCs reduce organ dysfunction/injury, systemic inflammation and mortality in patients with septic shock and severe neutropenia. The main goal of the study is to evaluate the impact of MSCs therapy on organ dysfunction/injury, systemic inflammation and 28-day mortality in patients with septic shock and severe neutropenia. All patients will be randomized in two groups: control group (standard treatment of septic shock) and MSCs-group (standard treatment of septic shock + MSCs infusion of 1-2 millions/kg/ day).
We hypothesized that early exercise rehabilitation for patients with severe sepsis or septic shock would decrease their functional disability and cognitive impairment. We plan to enroll patients with severe sepsis and septic shock who admitted an urban teaching hospital in Seoul, South Korea via ER. We will randomize those subjects into the intervention group which will take a standardized rehabilitation with routine clinical care for sepsis and the control group which will take routine clinical care for sepsis. And, we plan to assess their functional activity using ADL, IADL and SF-36, and cognitive function using MMSE at the time of enrollment, 28 days, and 6 months later.
The purpose of this study is to compare the tendency of plasma concentration and clearance of procalcitonin in the first 24 and 48 hours of management of patients with severe sepsis and septic shock with another marker of early prognosis represented by 48 hours delta sofa.
Sepsis is responsible for 50% of all acute kidney injury (AKI) in intensive care units (ICUs), contributing greatly to multiple organ dysfunction syndrome (MODS). Special types of continuous renal replacement therapies (CRRT) have been proposed as adjuvant therapies for septic shock due to their ability to remove middle molecular weight molecules such as inflammatory mediators involved in MODS pathophysiology. These therapies are called extracorporeal " blood purification " therapies. When CRRT is used, an anticoagulation is required to prevent clotting of the extracorporeal circuit, possibly causing bleeding in selected patients. Many anticoagulation strategies have been proposed and the most commonly used in 2013 is still unfractionated heparin. Regional citrate anticoagulation (RCA) is an interesting alternative as it dramatically decreases the bleeding risk. The investigators hypothesize that the use of citrate with Super High Flux Continuous Veno-Venus Hemodialysis (SHF-CVVHD) would be highly beneficial over time by preserving the filter effectiveness via limiting protein adhesion (which subsequently reduces filter pore sizes (protein cake)), as compared to heparin. Consequently, higher clearances of the inflammatory mediators could be maintained over time with citrate as compared to heparin anticoagulation. In other words, for the same duration of filter use, middle molecular weight molecules and cytokines clearances would be greater with citrate as compared to heparin. To test this hypothesis, the investigators will perform a clinical randomized controlled trial which aim would be to compare middle molecular weight molecules and cytokines clearances in SHF-CVVHD using RCA versus systemic heparin anticoagulation in septic patients with AKI.
Delirium in the ICU is a prevalent problem occurring in up to 80% of ICU patients. A potential cause of delirium in ICU patients could be cerebral hypoxia. Septic shock is associated with high rates of delirium. The aim of this pilot study is two fold. First, to determine the feasibility and potential challenges of measuring cerebral oxygenation in ICU patients with severe sepsis and septic shock. And second, to see if the incidence and magnitude of cerebral desaturations correlated with ICU acquired delirium as measured by the Confusion Assessment Method (CAM) scores.
The Patient evaluated in Emergency room since admission and detailed history and clinical examination done .The in hospital cases where sepsis is the culprit and shifted to Intensive Care Unit (ICU) in view of septic shock were included since onset of shock. Initial fluid resuscitation done and if the patient were no fluid responsive they were randomized into arms noradrenaline or terlipressin and the dose escalated to achieve the primary objectives. At the same time the strict vitals monitoring and standard medical therapy for sepsis including antibiotics and other supportive therapy continued. The patients were followed up till discharge, death or up to 28days after enrollment into the protocol (whichever the longest). The detail methodology has been explained in column 14 later.
The aim of the study is to evaluate whether fluid responsiveness of the critically ill patient can be assessed by analysing the PEEP-induced hemodynamic effects to systolic blood pressure, pulse pressure, aortic blood flow, aortic time-velocity integral and left ventricular end diastolic area measured with transesophageal echocardiography (PEEP-test). The chances are compared to increase of CI after volume expansion (gold standard). In clinical practise, it would be especially relevant if PEEP-induced changes in arterial pressure variations could be used in evaluation of volume status and fluid responsiveness. However, as ECHO-derived variables are used in greater extent to guide the treatment with inappropriate evidence, the simultaneous registration of ECHO-derived hemodynamic measurements is essential in the study design.
The main objectives of the study are 1)to examine the immediate (2 hours) and delayed (8 hours) effects of intravenous hydrocortison on macro and microvascular post-ischemic vasoreactivity, in septic shock adult patients; 2) to examine possible correlations between post-ischemic flow-mediated dilation (FMD) of the brachial artery (assessed by ultrasound imaging) and post-ischemic recovery slope of the thenar oxygen saturation (StO2) (assessed by near-infrared spectroscopy).
Objective: to test the hypothesis that recombinant activated protein C (aPC) therapy improves the microcirculation of severe septic patients. Design: Prospective, open study. Setting: University 12-beds intensive care unit. Patients: Septic patients with at least two sepsis-induced organ failures occurring within 48 hours of the onset of sepsis were included in a one year period. Interventions: Patients who had no contraindication to aPC administration received aPC at a dose of 24 mcg/kg/h for 96 hours. Patients with contraindications to aPC infusion were considered as controls.
