Active clinical trials for "Shock"

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.

Blood platelets play a major role in the inflammatory response. A dysregulation of platelets activation may be one of the contributors to tissue damage in critically ill patients with septic shock. The main objective of this study is to compare platelet activation markers levels (including plasma concentration in CD154, beta thromboglobulin, platelet factor 4, platelet microparticles, soluble CD62, RANTES, GRO-alpha and HMGB-1) at the early phase of a septic shock and a systemic inflammatory response syndrome (SIRS).

Cardiogenic shock is associated with a high mortality. The microbiome is a double-edged sword which can convey protective and detrimental cardiovascular effects. The significance of the enteral micobiome on cardiovascular mortality of patients with cardiogenic shock is still not known. This study aims to provide a deeper understanding of the role of the enteral microbiome and microbiome dependent metabolites in mortality and disease progression of patients with cardiogenic shock.

This protocol is designed to develop a novel first-in-class treatment for use in critical care and life-threatening condition of hypovolemic shock with unmet need and is of national interest. Shock is a life-threatening condition of circulatory failure. It is a state of cellular and tissue hypoxia due to reduced oxygen delivery and/or increased oxygen consumption or inadequate oxygen utilization. Shock most commonly occurs when there is circulatory failure leading to reduced tissue perfusion. There are four types of shock: distributive, cardiogenic, hypovolemic, and obstructive. However, these are not exclusive, and many patients with circulatory failure have a combination of more than one form of shock (multifactorial shock).

Intensive Care Unit (ICU) patients are known to lose muscle mass and function for many reasons, ranging from prolonged immobilization, to the effects of ICU treatments such as mechanical ventilation (MV), to the critical illness itself. Ultrasonography (US) is widely used in the ICU setting and has greatly evolved in the last decades, since it allows the non-invasive assessment of different structures, using radiation-free and user-friendly technology; its application for the assessment or the skeletal muscle is a promising tool and might help detecting muscle changes and thus several dysfunctions during early stages of ICU stay. By using skeletal muscle ultrasound at both diaphragm and peripheral levels, the overall aim of this study is to improve knowledge in the early detection of muscle dysfunction and weakness , and their relationship with mechanical ventilation weaning and muscle strength, in critically ill patients suffering from septic shock.

Sepsis is an increasingly recognised burden to healthcare systems worldwide. Intravenous fluid therapy is a common first-line intervention recommended by international guidelines. Hyperoncotic preparations of human albumin solution are widely available, but their efficacy has yet to be proven. This randomised feasibility trial will test whether it is feasible to administer hyperoncotic albumin solutions as both fluid resuscitation and as a regular supplement in patients with early septic shock.

Long term prognosis of cardiogenic shock is related to the resolution of haemodynamic failure, associated visceral failure and the recovery of an adequate myocardial function. In the immediate aftermath of cardiogenic shock, after catecholamines weaning, there are no recommendations on cardiovascular treatments that would improve this long term prognosis. Indeed, the standard cardiovascular treatments such as inhibitors of the renin-angiotensin and aldosterone system and beta-blockers have hypotensive and negative inotropic effects and may worsen the renal function. In practice, given their side effects, they are not prescribed in the immediate aftermath of cardiogenic shock. Sodium-glucose co-transporter 2 (iSGLT2) inhibitors are now an integral part of the drug management of chronic heart failure and the EMPULSE-HF trial has just demonstrated a benefit in acute heart failure (PMID: 35228754). Several pivotal clinical trials have demonstrated a significant effect of iSGLT2 on the survival and the risk of re hospitalisation for heart failure (PMID: 32865377, 31535829, 33200892). Our hypothesis is that, in patients in cardiogenic shock, early treatment with Empaglifozin in addition to the standard management could reduce mortality and morbidity (death, transplantation/LVAD and rehospitalisation for heart failure) and improve myocardial function at 12 weeks, compared with standard management alone.

Shock is a major risk factor for mortality among patients admitted to intensive care units (ICUs). Since various hemodynamic strategies uniformly delivered to patients with shock have failed to improve clinically relevant outcomes, individualized approaches for shock supported by robust evidence are required. This study will be a prospective, multicenter, parallel-group, single-blind, randomized controlled trial. The investigators will randomly assign 800 critically ill patients requiring norepinephrine infusion to the renin-guided or usual care groups. The investigators hypothesize that renin-guided hemodynamic management, compared to usual care, can reduce a composite of mortality and acute kidney injury (AKI) progression in patients requiring vasopressor support.

Prolonged circulatory shock is associated with marked disturbances in vascular supply to the brain, and endothelial dysfunction which can lead to disseminated intravascular coagulation and microvascular thrombosis. Pituitary dysfunction is documented following post-partum hemorrhage, traumatic brain injury and subarachnoid hemorrhage, which also affect blood flow to the pituitary. However, there are no studies assessing pituitary function in the aftermath of recovery from shock. This will be a prospective observational study of patients admitted in Critical Care Medicine (CCM) ICU who have recovered from prolonged septic shock (Lasting for a period of > 24 hours). Blood samples of the participants will be estimated at the time of discharge from the ICU and at 6 months post discharge. Investigators will estimate fasting serum cortisol, TSH, Free T4, Testosterone (in males), Oestrogen (in females), LH, FSH, Prolactin, IGF-1 and plasma ACTH in all participants at both time points (at the time of ICU discharge and at 6-months follow-up). Participants who have borderline serum cortisol values (138-400 nmol/l) will be subjected to 250ug ACTH stimulation test. Expected outcome of the proposed study is to know proportion of patients having pituitary hormone axis dysfunction. Investigators will also look for pituitary dysfunction persist or revert, or there are new onset dysfunction at 6 month follow up. This would have major implications in the follow up and management of ICU survivors.

The study aims to investigate clinically and prognostically relevant parameters in patients with cardiogenic shock within a monocentric observational clinical register.
