Active clinical trials for "Shock"

The purpose of this observational study is to determine whether endotoxin levels and/or their trends can be considered predictive of morbility or mortality in septic shock caused by gram-negative bacteria, searching also for a possible correlation with Simplified Acute Physiology Score (SAPS II), Sequential Organ Failure Assessment (SOFA), White Blood Cells (WBC) and Platelets (PLT).

A prospective longitudinal study similar to the one performed by Claushuis and colleagues (2016) will be performed in order to further understand the epidemiology and clinical relationship between platelet levels and mortality secondary to septic shock in a different population. The primary objective is to compare the mortality due to septic shock between patients with thrombocytopenia and patients with normal platelet levels in the ICU of the General Hospital of León, Gto. The secondary objectives are to identify the association between mortality due to septic shock and mild, moderate and severe thrombocytopenia in patients admitted to the ICU at 30, 60 and 90 days. Research questions Is there an association between thrombocytopenia and mortality due to septic shock in patients admitted to the critical medicine service? Our hypotheses are that: 1. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with thrombocytopenia than in patients normal platelet counts. Is there an association between the degree of thrombocytopenia and mortality from septic shock in patients admitted to the critical medicine service? Our hypotheses are that: Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with mild thrombocytopenia than in patients without thrombocytopenia. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with moderate thrombocytopenia than in patients without thrombocytopenia. Mortality from septic shock and thrombocytopenia at 30, 60 and 90 days will be higher in patients with severe thrombocytopenia than in patients without thrombocytopenia.

Cardiogenic shock (CC) is one of the major challenges of current cardiology. Despite the difficulty of establishing a strict and consensual definition, it is accepted that the CC clinically corresponds to persistent hypotension (systolic blood pressure 90 mmHg for at least 30 minutes or need for vasopressor support) associated with signs of visceral hypoperfusion (confusion, mottling, oliguria, hyperlactatemia), and hemodynamic with a lowered heart index ( 1.8 L/min/m2) despite appropriate or high filling pressures. This definition of the European Society of Cardiology (ESC) masks however the great variability of hemodynamic tables grouped under the term of CC and severity levels, also variable.However, it was suggested that the etiology of CC influenced both its hemodynamic profile and therefore its therapeutic management but also its prognosis in the medium and long term.

The purpose of this study is to assess the effect of norepinephrine and fluid expansion on capillary refill time during septic shock.

Goals Primary: compare changes in norepinephrine requirements before and after hemoperfusion (HP) treatment. Secondary: demonstrate the decrease in levels of IL-6 , assess the total and individual change of SEQUENTIAL ORGAN FAILURE ASSESSMENT (SOFA), establish the resolution of shock , clearance of lactate , and mortality at discharge from INTENSIVE CARE UNIT (ICU), at 30 and 60 days.

The extent and duration of tissue hypoxia is a major determinant of outcome following major, high-risk surgery and in critical illness. Prompt restoration of tissue oxygenation through resuscitation in all likelihood improves outcomes. There are currently no bedside monitors in clinical practice that track tissue perfusion per se, instead clinicians rely on crude surrogates such as heart rate and blood pressure, urine output, serum lactate of global flow (cardiac output) monitoring. This is a first-in-man trial of a new device to measure tissue oxygenation in real time in a major, high-risk surgical and critical care cohort. The device consists of an oxygen sensing probe incorporated into a modified urinary catheter, which relies on photoluminescence technology and the quenching properties of oxygen. Once inserted, the drained bladder collapses round and envelopes the probe which continuously measures tissue oxygenation of the bladder urothelium. The investigators hope to (i) Establish that tissue oxygenation can be safely monitored using this technology, deployed in this way. (ii) Define a normal range for bladder tissue oxygenation in man as measured using this device. (iii) Compare tissue oxygenation against other markers of perfusion status in current clinical practice and assess its performance at detecting inadequate perfusion against these other modalities. (iv) assess the diagnostic and prognostic capabilities of the tissue oxygenation monitoring at detecting hypo-perfusion and predicting outcome. (v) Further assess the tissue response to an 'oxygen challenge' in identifying occult hypo-perfusion. (vi). Provide pilot work required to inform future, interventional studies where similar patients would be resuscitated to tissue oxygenation targets alongside routine clinical practice.

Sepsis is a common life-threatening inflammatory response to infection and is the leading cause of death in the intensive care unit. Septic patients exhibit a complex immunosuppressive response affecting both innate and adaptive components of immunity, with a possible link to nosocomial infections. However, the molecular and cellular mechanisms resulting in secondary immunosuppression remain poorly understood, but may involve the antigen-presenting cells (APC, including dendritic cells and monocytes/macrophages) that link innate and adaptive immunity. Furthermore, the increasing phenotypic and functional heterogeneity of APC subsets raise the question of their respective role in sepsis. We propose to address the pathophysiologal role of APC using systems biology approaches in human sepsis. The objective is to go from low- to high-resolution analysis of APC subset diversity and underlying molecular and functional features in sepsis. The global objective will be reached through: Systematic description and phenotypic analysis of circulating APC subsets in sepsis Association of APC subsets distribution, phenotype and function with severe sepsis physiopathology and relevant clinical outcomes (ICU-acquired infections and death) High-resolution molecular profiling of circulating APC subsets using population level and single cell RNAseq. To this aim, the investigator designed a prospective interventional study in order to collect blood samples at significant time points in patients with sepsis or septic shock (the population of interest) and relevant control subjects, either critically ill patients with non-septic acute circulatory failure or age-matched healthy subjects. The study's intervention is limited to additional blood samples. The risks and constraints are related to additional blood samples (maximum 120mL), which will be performed either from an arterial catheter when present in ICU patients, or from a venous puncture for patients without arterial catheters and for healthy volunteers.

terlipressin is given to refractory septic shock patients who do not respond to noradrenalin in Israel and Europe. It is given by bolus injection. we attempt to investigate weather it is better to give it by continuous drip and avoid abrupt changes in BP and heart function

A prospective, 2-arm, single-blind, randomized controlled clinical feasibility trial design is planned. Forty CCI survivors will be randomized (1:1) to either the PS-PICS (peer support) intervention or usual care (control) group.
