View clinical trials related to Septic Shock.
Filter by:Cirrhotic 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.
In recent years, many studies have pointed out that bacterial toxin and cytokine storm are the main causes of shock and multiple organ failure in patients with sepsis. Endotoxin is the main vehicle for systemic inflammatory reaction caused by gram-negative bacteria which induce sepsis. Endotoxin binds to Toll- Like receptor 4 (TLR4) trigger a cytokine storm. The amount of endotoxin is associated with shock, insufficient intestinal perfusion, and poor prognosis. Therefore, clinicians try to use various methods to antagonize the action of endotoxin, which can reduce the cytokine storm and inflammatory response to improve the prognosis of sepsis. Continuous venous venous hemofiltration plays a role in blood purification in septic shock. With different hemofiltration filters, it has different effects. By removing the inflammatory mediators caused by bacterial toxins and cytokines, shock can be improved. The study plans to receive patients with septic shock and use a hemofiltration filter that adsorbs endotoxin and removes cytokines (oXiris, Baxter Healthcare) to perform continuous venous venous hemofiltration in addition to basic septic shock resuscitation. The effect on the concentration of cytokines in the blood, the infusion dose of inotropics, the fluid balances, and the degree of organ damage was evaluated. It is hoped that the results of this pilot study can lead us to subsequent randomized clinical trials to explore whether this filter can improve the prognosis of septic shock patients.
Alterations of acid-base equilibrium are very common in critically ill patients and understanding their pathophysiology can be important to improve clinical treatment.
The objective is to determine the sensitivity and specificity via Receiver Operating Characteristic (ROC) curve of Global Longitudinal Strain (GLS) The secondary objectives are the same for the change in the amount of carbon dioxide exhaled (ΔEtCO2) and dynamic arterial elastance (Eadyn). it will also determine the sensitivity and specificity of these indices, either individually or combined to determine persistent responders to volemic expansion.
Septic shock is common in patients admitted to intensive care and hospital mortality occurs in close to 50% of these patients. In half of the cases, death occurs within the first 72 hours in a context of multiple organ failure that does not respond to conventional therapies, particularly circulatory therapies, despite increasing doses of catecholamines. Vasopressor resistance in septic patients defines refractory septic shock. In one study (Conrad et al. 2015), the increase in blood pressure observed with an infusion of increasing doses of phenylephrine (dose-response curve) made it possible to quickly and clearly identify patients resistant to vasopressors at a high risk of death by refractory shock (ROC AUC 0.92). This resistance is due in particular to a downregulation of α1 adrenergic receptors, linked to sympathetic hyper activation associated with septic shock. To date, there is no validated therapy in this situation. However, experimental data have shown that the administration of α2 agonists, usually used for their sedative (dexmedetomidine) or anti-hypertensive (clonidine) effect, normalizes sympathetic activity towards basal values. In animals, α2 agonists restore the sensitivity of alpha1 adrenergic receptors, resulting in improved vasopressor sensitivity and survival. In humans, a beneficial effect on mortality was suggested in the first trial testing dexmedetomidine in septic patients in 2017. This effect was observed especially in the most severe patients, suggesting a restoration of sensitivity to vasopressors. The hypothesis is that the administration of dexmedetomidine in patients in refractory septic shock may improve response to phenylephrine and decrease resistance to vasopressors. This pilot study could lay the foundation for a randomized controlled trial.
Severe sepsis and septic shock remain the leading causes of child mortality worldwide. Sepsis is a complex process that ultimately leads to circulation disorders, organ perfusion abnormalities, capillary leakage, tissue hypoxia, and organ failure. The difficulty of clinical treatment is microcirculation and mitochondrial dysfunction in septic shock. Once shock enters the stage of microcirculation failure, conventional treatment is ineffective. ECMO can effectively support the circulatory system and provide good oxygen delivery, but there are many controversies in clinical treatment. 1) whether ECMO can effectively improve the clinical prognosis of children with septic shock; 2) appropriate timing for ECMO intervention; 3) which key clinical factors affect the effect of ECMO treatment. This study intends to adopt a multi-center, prospective, non-randomized controlled trial design, and the main research hypothesis is whether ECMO treatment can improve the success of discharge survival of children with septic shock.
Long-term cognitive dysfunction greatly influences patient's quality of life after critical illness. However,its neurophysiological basis remains unknown.This is a 3 year fMRI study conducted at the Jiangyin people's Hospital. This study utilize resting-state functional magnetic resonance imaging(fMRI) to investigate the regional alterations in survivors with cognitive impairment.Further, the investigators hypothesize that these regional changes in fMRI activity are predictive of cognitive impairment.
This study evaluates the association between plasmatic levels of Mid Regional Proadrenomedullin (MR-proADM) and the sublingual microcirculation in critical care patients admitted with infection, sepsis or septic shock.
Although more than 50% of survivors of critical illness experience one or more post-intensive care syndrome (PICS) problems, there are still no validated interventions for the management of PICS. The long-term goal of this study is to develop and refine in-person and telehealth strategies for the delivery of Intensive Care Unit (ICU) recovery care for the treatment of PICS.
The development of acute kidney injury (AKI) during septic shock is frequent and is associated with a high mortality rate. The reason of this increased mortality despite the use of renal replacement therapy is still unknown. The deleterious effects of uremic toxins (solutes accumulating with the loss of kidney function) has risen for the last decade in chronic kidney disease patients. Among those solutes, indoxyl sulfate (IS) is associated with the development of cardiovascular complications and impairment of immune response. The role of uremic toxins and particularly IS in the prognostic of septic kidney injury is unknown. The investigators propose to analyze the relation between the serum concentration of IS and the mortality of patients hospitalized for a septic shock who developed an AKI.
