Filter by:The investigators aim to perform a randomized, double-blind, placebo-controlled trial to investigate the efficacy of midodrine in decreasing time to IV vasopressor liberation in patients with septic shock.
A randomized control trial among patients with septic shock, studying the incidence, progression and recovery of AKI.
Veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) is indicated as a haemodynamic rescue strategy in decompensated acute or chronic heart failure presenting as cardiogenic shock. It has been used across aeitologies including post-myocardial infarction, dilated cardiomyopathy, acute myocarditis and in post-cardiotomy shock. VA ECMO has a number of effects on the circulation including improved end-organ perfusion and possibly improved coronary perfusion, and is a bridge to further therapies including permanent advanced mechanical circulatory support, cardiac transplantation and to cardiac recovery. Left ventricular assist devices (LVADs) provide long-term mechanical circulatory support and also profoundly mechanically unload the left ventricle. Multiple clinical studies have documented cardiac recovery using LVAD therapy, with a rate between 10-60% in selected populations. A large body of basic science has documented the pivotal role of mechanical load in determining ventricular contractile performance across species. Therefore both clinical data and basic laboratory studies support the notion that profound ventricular unloading may result in improved cardiac performance through a variety of mechanisms ranging from triggered de novo cardiomyocyte proliferation, subcellular calcium handling reverse remodeling, changes to the extracellular matrix of the heart, reverse remodeling of the neurohormal milleu, amongst many others. One of the major deficiencies of peripheral VA-ECMO is its lack of left ventricular unloading, with associated pulmonary congestion, which can derail clinical improvement and hamper cardiac recovery. Indeed, percutaneous VA-ECMO increases LV afterload due to the retrograde blood flow, and because of the lack of venting, there may be progressive LV distension. These conditions can result in a congested, pressure-overloaded ventricle, even in the absence of echocardiographic ventricular distension. This may be ameliorated with the addition of ventricular mechanical unloading using percutaneous therapies including the percutaneous left ventricular device, Impella CP. On the platform of VA-ECMO, the addition of an Impella device to reduce ventricular loading results in improved survival and recovery of ventricular performance in the setting of cardiogenic shock. In a number of small studies, the use of additional means to unload the ventricle, principally Impella, results in cardiac recovery and less ventricular distension. In chronic heart failure, direct ventricular unloading is critical to cardiac recovery. The objective of this randomized study is to determine whether the addition of early direct ventricular unloading using Impella CP leads to higher rates of cardiac recovery, defined as survival free from mechanical circulatory support, heart transplantation or inotropic support at thirty days. This study will also examine the clinical, biochemical, echocardiographic and radiologic effects of VA ECMO with and without the addition of Impella CP to directly vent the left ventricle to address adjunct important questions such as the effects on pulmonary congestion.

The aim of this study is to determine the effects of fluid alternations, hemodynamic changes, mechanical ventilation, pharmacologic agents, positional changes, and comorbidities on the Peripheral Intravenous waveform Analysis (PIVA) signal.
Despite recent medical advances, sepsis and septic shock remain a major cause of death. Sepsis is a syndrome with a wide array of physiologic, pathologic, and biochemical abnormalities. Several studies have shown vitamin C have decreased the circulating pro-inflammatory cytokines and oxidative stress.Thiamine had favorable effects on pro-inflammatory cytokines, oxidative stress and cellular hypoxia.The use of hydrocortisone in combination with vitamin C will increase the transport of vitamin C into the cells; since the pro inflammatory cytokines have shown to decrease the expression of the sodium-vitamin C transporter-2 (SVCT2) while glucocorticoids increase the SVCT2 expression. A recent small retrospective study , showed a significant decrease in mortality when patients with severe sepsis and septic shock are treated with a combination of Hydrocortisone, Vitamin C, and Thiamine. Conducting a similar study with a prospective randomized design will give clinicians all over the world more answers and will help clinicians to provide better care to millions of patients using highly safe therapeutic regimen. The objective of the current study is to explore the clinical benefits of using a combination of hydrocortisone, vitamin C, and thiamine (triple therapy) for the management of septic shock. To achieve this objective, we will compare two alternative treatment strategies, either triple therapy or usual care in patients with septic shock. First aim: To assess the effectiveness of the triple therapy for septic shock Second aim: To assess the safety of triple therapy
This study is a pragmatic open-label international randomized trial comparing therapeutic dose intravenous unfractionated heparin (UFH) to standard care venous thromboprophylaxis in patients diagnosed with septic shock.
There is a knowledge gap regarding the optimal initial fluid to achieve effective resuscitation and improved outcomes in septic shock. The purpose of this study is to compare initial resuscitation with plasma to initial resuscitation with balanced crystalloids.
The global burden of sepsis is substantial with an estimated 15 to 19 million cases per year; the vast majority of these cases occur in low income countries. New therapeutic approaches to sepsis are desperately required; considering the global burden of sepsis these interventions should be effective, cheap, safe and readily available. The aim is to study the synergistic effect of vitamin C, hydrocortisone and thiamine on survival in patients with severe sepsis and septic shock.
Haemodynamic insufficiency after birth is seen commonly in babies born prematurely and is associated with adverse outcomes. In current clinical practice, a combination of blood pressure and clinical signs is used to guide therapy. However, blood pressure is a poor surrogate of systemic and organ (brain) blood flow distribution during transitional circulation. This state is characterised by increased peripheral vascular resistance and increased afterload causing myocardial depression and impaired blood flow distribution in spite of 'normal' blood pressure. Echocardiography-Doppler (Echo-D) measurement of superior vena cava (SVC) flow has been proposed as a more clinically relevant marker of circulatory impairment shortly after birth than systemic hypotension. When there is low SVC flow, several small-scale clinical trials have suggested dobutamine as the optimal therapeutic option. However the associations between SVC flow and short- and long- term outcomes are not strong enough to allow SVC flow alone to be the basis for the inclusion of patients into a confirmatory trial to demonstrate the efficacy and safety of dobutamine. NeoCirc-001 - The primary objective is to answer some important questions required for the design of a subsequent placebo-controlled trial (NeoCirc-003), which will evaluate the effectiveness of a new neonatal formulation of dobutamine to treat haemodynamic insufficiency in the first 72 hours after birth in babies born at less than 33 weeks' gestation. Observational data will be collected from this population with a view to determining the degree to which diagnostic measures influence treatment decisions. The primary outcome is death or worst cranial ultrasound (CUS) appearance at or before 36 weeks' gestation. NeoCirc-001A - The primary objective is to estimate the elimination half-life, and consequently the time to steady-state of dobutamine in extremely premature neonates. NeoCirc-001B - The primary objective is to construct a population pharmacokinetic pharmacodynamic model that will be validated using samples collected during the confirmatory trial (NeoCirc-003).
