Filter by:Record the renal resistive index and hemodynamic parameters ( record the cardiac output and stroke volume if the patient's next to kin agree to undertake a PiCCO monitoring ) before and after resuscitation for severe sepsis or septic shock patients, to determine whether the changes of resistive index or hemodynamic parameters, especially the cardiac output can be a better parameter to predict AKI
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).
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.
Compared with AN69 hemofilter, AN69 ST hemofilter may prolong the time of hemofilter and decrease the quantity of heparin during continuous renal replacement therapy in critically ill.
This study is to see whether the intravenous administration of methylene blue improves the outcome in severe sepsis and septic shock.
Septic shock remains the dominant cause of death in ICU's of the developed world with approximately 400,000 cases annually in the US and another 20,000 annually in Canada. While many retrospective and prospective reviews of septic shock patients have been undertaken worldwide, many key questions remain unanswered. These questions include the true incidence, associated morbidity and mortality of septic shock in North America, key factors associated with successful management and markers suggesting a high probability of a complicated clinical course. Part of the reason for the persistence of these questions, is the fact that previous and ongoing reviews of septic shock and severe sepsis have been either limited in number (typically <150) or biased by the need to be eligible for specific clinical trials (typically, non-eligible patients have not been followed and had data collected. We propose to examine specific questions within a temporally comprehensive cohort of septic shock patients by review of individual charts using a defined data-extraction template.
This study is designed to examine the early sequential cytokine responses during antibiotic therapy and resuscitation of septic shock in relation to clinical manifestations of disease. The specific objective is to obtain sequential serum samples from patients with septic shock, examine a broad range of cytokine responses (TNF, IL-1, IL-6, MIF, LIF, HMGB1, etc) in a rigorous manner and correlate these responses to administration of antibiotics, resuscitative efforts and physiologic responses to illness (temp, HR, blood pressure, WBC, etc).
Septic shock is a major cause of death in intensive care. Septic shock is often dominated by profound changes in organ functions, of which cardiac failure is one of the most severe. In septic shock, biological markers of cardiac stress are often elevated. It is not known to what extent this indicates structural damage to the heart, or in what way they correlate to echocardiographic signs of heart failure. Here, cardiac failure in ICU patients with septic shock is studied, using biological markers of cardiac stress, inflammatory parameters and echocardiography. Investigators hypothesize that biomarkers of cardiac stress correlate with echocardiographic signs of heart failure, and that they can predict an increased risk of death.
Thousands of children die from Sepsis following routine infections. Many of these deaths can be prevented with earlier recognition and focused management. No tools are currently available to recognize the signs of early sepsis in children. The investigators have developed a electronic health record-based tool that will recognize children with sepsis early and trigger an alert to their hospital caregivers. The caregivers will be prompted to launch a focused management bundle that can stabilize these children, prevent further deterioration and reduce their chances of sepsis related complications and death. The proposed study will test the validity and effectiveness of this electronic tool in reducing sepsis mortality rates.
