Active clinical trials for "Shock"

This is a randomized, double blind, single center trial to study of the effects of Ivabradine vs. Placebo on patients hospitalized for Stage D heart failure (HF)/ and cardiogenic shock (CS) who will require continuous infusion of Dobutamine and have developed sinus tachycardia (ST) (heart rate >100 beats/min). The aim of the study will be to assess the potential of Ivabradine to slow ST and improve hemodynamics in patients with stage D HF/CS on Dobutamine treatment.

Anaphylaxis is a potentially fatal condition with a prevalence between 0.05 and 2% in the general population. This is therefore a frequent reason for emergency visits. Its diagnosis is mainly based on the NIAID / FAAN2 criteria, developed in 2006. The treatment of the condition consists of administration of intramuscular (or intravenous) epinephrine and the hemodynamic support of the patient, if necessary. Various other agents are frequently administered (class I and II antihistamines, corticosteroids) but their role is recognized to be less central than that of epinephrine. The relevance of corticosteroids in reducing the risk of rebound reaction is even questioned. After anaphylaxis, a serious phenomenon called a "biphasic reaction" can occur. This reaction is the return of symptoms of anaphylaxis resolution of the initial episode. The theoretical risk of a rebound reaction, or biphasic reaction, is conventionally described up to 72 hours after the initial anaphylactic event. Biphasic reaction is defined as a recurrence or occurrence of new signs or symptoms after resolution of the initial reaction, without re-exposure to the allergen. The potential occurrence of a biphasic reaction often warrants observation of patients for several hours in emergency departments following management of the initial anaphylaxis. Although recommendations and guidelines generally suggest observation times of four to six hours, there is no clear consensus or convincing evidence to guide this conduct. It sometimes even is suggested to observe patients for up to 24 hours. Problem: To date, there are no prognostic factors to identify a patient at greater risk who would benefit from such an observation. As these reactions are a relatively rare phenomenon (i.e. 4 to 5%, but which could go up to 20% according to some sources and the symptoms observed are usually less significant than during the initial presentation, it is therefore possible that a prolonged observation period may not be necessary for some patients who do not have high risk factors for biphasic reaction. In the current context of the growing number of people in emergency rooms and limited ressources, it seems essential to identify low risk patients in order to discharge them quicker and safely by limiting unnecessary observation periods. Objective: Identify and evaluate in a prospective manner previously derived (literature review and preliminary rules derivation already completed) clinical decision rules that are simple, generalizable and valid which could therefore become an interesting assets for the modern practice of emergency medicine as regards to post anaphylaxis rebound reaction risk stratification. It appears likely that some patients who have suffered an anaphylactic reaction could be safely discharged much earlier than in current practices. The rules would give clear guidelines to clinicians especially those working in lower flow settings, where clinical experience with the disease is less developed. Ultimately, these rules would also be relevant for teaching purposes for the various learners who do internships in emergency rooms.

Early detection of ongoing hemorrhage (OH) before onset of hemorrhagic shock is a universally acknowledged great unmet need, and particularly important after traumatic injury. Delays in the detection of OH are associated with a "failure to rescue" and a dramatic deterioration in prognosis once the onset of clinically frank shock has occurred. An early alert to the presence of OH would save countless lives. This is a single site study, enrolling 48 patients undergoing liver resection in a "no significant risk" prospective clinical trial to: 1) further identify a minimal subset of noninvasive measurement technologies necessary for the desired diagnostic performance, 2) validate the performance of our Phase I algorithm, and 3) re-train the algorithm to a Phase II human iteration. The main outcome variables are non-invasive measurements that will be used for machine learning, not real-time patient management. The data generated will be used later for discovery and validation in traditional and innovative machine learning.

Prospective monocentric study designed firstly to estimate the proportion of patients who tolerated the continuation of the COVID-19 2nd injection (absence of anaphylactic manifestations). secondly, to know the proportion of definite anaphylactic reactions in cases of suspected anaphylaxis after the first administration of a COVID-19 vaccine the very complete allergological explorations with both the clinical side, skin tests and biological tests will allow us to highlight the responsibility or not of the components of the vaccine,in particular of the excipients (PEG2000, PS80 and tromethamine) in anaphylactic reactions to COVID-19 vaccines A biological collection will be set up during this clinical study in order to study the immunological mechanisms; the effector cells and the signalling pathways involved in these reactions.

This study is to see whether the intravenous administration of methylene blue improves the outcome in severe sepsis and septic shock.

The purpose of the study is to compare the efficacy of levosimendan with that of dobutamine in patients with unstable hemodynamics (shock).

Septic shock is a devastating condition often observed in ICU. It is characterized by pro-inflammatory and immune responses, organ failures, high incidence of AKI and lethality. Fluid resuscitation is pivotal as supportive therapy. At present, there are no effective therapies to improve survival of such clinical condition, often characterized by a mortality as high as 40% during the first 90 days from diagnosis. This project proposes a large 2-by-2 factorial randomized clinical trial testing the efficacy of albumin and the low- chloride balanced crystalloid solutions (either Ringer Lactate, Ringer Acetate, or Crystalsol - BAL) in septic shock. The investigators have recently concluded a multicenter, randomized trial, the ALBIOS trial, in which, in a post-hoc analysis, albumin, in addition to crystalloids, reduced 90-day mortality in patients with septic shock, as compared to crystalloids alone (Caironi P et al, 2014). Crystalloids with supra-physiological chloride content may deteriorate renal perfusion, increasing the risk of acute kidney injury (AKI) and mortality.

Proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors increase LDL receptors by decreasing its degradation. In sepsis the pathogenic substances, endotoxin, lipoteichoic acid, phospholipomannan are the main cause of the ongoing inflammation that causes the severe damage and outcome. these substances are removed from the blood by the LDL receptors. By administering PCSK9 inhibitors to patients with sepsis/septic shock this inflammatory response can be stopped and by doing so improve the patients outcome.

Prevalence of cardiogenic shock in acute coronary syndrome patients is reported at about 5-8% with high fatality. Revascularization approach has already known as the standard of care, but the usage of intra-aortic balloon pump (IABP) as mechanical circulatory support is still a controversy. IABP SHOCK II trial revealed that short-term mortality did not improved by IABP but there are several essential variabels related to mortality that are not considered in the study which are IABP initiation time and weaning protocol.This study aim to evalute the effect of IABP prior to revascularization on mortality of patients with myocardial infarction complicated with shock. 92 subjects will be enrolled in this randomized controlled trial into two groups, with and without IABP. IABP group will be receiving the intervention prior to revascularization. The primary outcomes to be sought are in-hospital and 30-day mortality after revascularization. IABP effects measured by various indicators such as Global Longitudinal Strain by echocardiography on the 1st and 3rd day, NTproBNP and ST2 level on the 1st, 3rd and 5th day, effective lactate clearance and ureum creatinine level on the 1st and 3rd day and will be compared between two groups. Continous variabel will be presented in mean ± deviation standard or median, and analized with Student's t test or Mann-Whitney U test as appropriate.

Patients with septic shock would be screened. Following this, patients meeting the inclusion and exclusion criteria will be screened and randomized to the two treatment groups. Standard criteria will be considered to define refractoriness to fluids. In all patients, baseline endotoxin activity assay and blood and urine sample will be stored for looking at the effect of therapy on these factors. Septic shock would be defined as clinical construct of sepsis with persisting hypotension requiring vasopressors to maintain MAP>=65 mm of Hg and having a serum lactate >2 mmol/L despite adequate volume resuscitation. Patients assigned to the treatment arm and who do not already have access for dialysis will have a standard hemodialysis catheter inserted in one of the femoral veins by the physician. Hemoperfusion will be carried out for one session within 12 hours for all randomized patient using the adsorption columns for Jianfan Biotechnology Co., Zhuhai, China). The hemoperfusion apparatus will be connected in front of the hemodialyzer in series. The procedure would be done for 2 hours without use of heparin with use of normal saline for pipeline flushing. In patients who also require hemodialysis the dialysis would subsequently be continued. Subsequent sessions of therapy would be done for patients (if required).
