Filter by:This pilot study is designed to investigate the effect of inhaled nitric oxide on cardiac, pulmonary artery, and systemic hemodynamics at various time points during venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Patients who have been initiated on VA-ECMO will be invited to participate. Inhaled nitric oxide (iNO) will be used early after VA-ECMO cannulation (once consent is obtained). After baseline hemodynamic, biochemical, and echocardiographic parameters are assessed, iNO will be initiated and all parameters will be reassessed after 30 minutes and 6 hours. Inhaled nitric oxide will then be discontinued and all parameters repeated. At the time of VA-ECMO weaning (timing determined by clinical team), iNO will be reinitiated with repeat assessment of hemodynamic, biochemical, and echocardiographic parameters both prior to the wean and after the wean (whether successful or not).
Extracorporeal life support (ECLS), also known as extracorporeal membrane oxygenation (ECMO), is an extracorporeal technique of providing effective cardiac and respiratory support to patients with lungs and/or heart failure. There was a growth in ECLS cases, centers, and center scale in China during the past decade. This multi-center registry was conducted by Chinese Society of Extracorporeal Life Support. The objectives were to investigate China statistics of ECLS and to evaluate the short-term and long-term outcomes of patients with ECLS.
The investigation of patient characteristics and prognostic factors of the patients presented with cardiogenic shock (CS) will guide us to identify the better management strategy for these critically ill patients. Mechanical circulatory support (MCS) may improve the prognosis of some of severe subset of CS patients. The better understanding of the indications of initiation and weaning of MCS will improve the prognosis of critically ill CS patients.
Cardiogenic shock is a condition of low cardiac output that represents the end of a progressive deterioration of cardiac function. The main cause is ischemic heart disease but there are several causes of non-ischemic nature including sepsis. Sepsis is characterized by a picture of organ dysfunction caused by an altered response of the body to an infection. Its most serious form is septic shock, defined as a picture of sepsis in which the underlying abnormalities in the cardiovascular system and cellular metabolism are such as to increase mortality. An organ failure correlates directly with the function of others and this interdependence is especially evident when a cardiovascular failure is established. 3 Cardiac dysfunction in sepsis can be defined as that of a syndrome characterized by low cardiac output not related to myocardial ischemia. The use of levosimendan in cardiogenic shock during sepsis was first described in a 2005 case report. Since then there have been small studies and other case reports that have shown improvements in right and left ventricular contractility, ventricular coupling, cardiopulmonary performance, global oxygen transport, renal and splanchnic perfusion when compared to dobutamine and placebo. Other beneficial effects of this drug have emerged, including an anti-inflammatory, antioxidant and antiapoptotic action with a possible protection from ischemia-reperfusion damage. The present study aims to evaluate the correct use of levosimendan, after the occurrence of cardiogenic shock on a low cardiac index has been ascertained, with the aim of weaning from inotropic drugs in infusion.
The project's main goal is to collect baseline clinical and procedural data as well as to assess clinical outcomes for all patients undergoing ECMO or Impella implantation at all included sites. All patients undergoing ECMO and/or IMPELLA implantation will be prospectively registered. Device use is according to the decision of the treating physician and independent of this registry.
Venoarterial extracorporeal membrane oxygenation (VA ECMO)—also referred to as extracorporeal life support—is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange. The objective of this observational, cohort study is to evaluate the short-term and long-term outcomes of patients with VA ECMO.
The cardiogenic shock is characterized by an alteration of organs function following a decrease in cardiac output linked to an impairment of cardiac performance. The prognosis remains poor with mortality between 40 and 50%. Nowadays, Extracorporeal Life Support (ECLS or VA-ECMO) is the referent therapy to restore blood flow in the body when medical treatment is not sufficient. Despite a good blood flow provided by the ECLS, many patients develop a severe hypotension (so called vasoplegia) due to a loss of vascular resistance mainly explained by the inflammatory response to shock and extracorporeal circulation. The treatment of this reaction includes vasopressors (Norepinephrine in usual care) and serum surrogate perfusion to achieve a mean arterial pressure (MAP) above 65 mmHg. The purpose of this study is to describe the patients with vasoplegia among a retrospective cohort of patients treated with an ECLS in our university center, over the 4 last years, to determine major complication rate (including death, kidney failure and arrythmias) and their outcome. This study will provide consistent data useful for further trials about targets of pressure and treatments to increase blood pressure during ECLS.
Cardiogenic shock (CGS) affects up to 10% of patients suffering acute coronary syndrome. It has a 30 day mortality of 45-50%. No pharmacological nor intervention/device trials have had any impact on this mortality in the last 20 years. The EURO SHOCK Trial (supported by the European Union Horizons 2020 programme) will randomise 428 patients with CGS following acute coronary syndrome from 44 EU centres to early intervention with Extra Corporeal Membrane Oxygenation (ECMO) therapy or to standard treatment (with no ECMO). This intervention is a high cost specialist centre procedure that warrants further investigation including economic appraisal. Multiple mechanistic and hypothesis generating sub-studies will be undertaken.
Passive leg raising (PLR) is routinely used to predict preload responsiveness in critically ill patients. However, real-time measurements of cardiac output are required to assess its effects. Some authors have suggested that in fluid non-responders, central venous pressure (CVP) increased markedly. By analogy with the CVP rules proposed by Weill et al to assess a fluid challenge, it has been hypothesized that an increase in CVP ≥ 5 mmHg during PLR can predict preload unresponsiveness. Objective Investigation of whether an increase in CVP ≥ 5 mmHg during PLR predict preload unresponsiveness diagnosed by the absence of increase in velocity-time integral (VTI) of the flow in the left ventricular outflow tract by more than 10% (4). Methods Critically ill patients with a central venous catheter in place and for whom the physician decided to test preload responsiveness by PLR were prospectively included. Transthoracic echocardiography was performed to obtain VTI. The CVP and VTI were measured before and during PLR.
Extracorporeal membrane oxygenation (ECMO) is a temporary mechanical circulatory support device for cardiogenic shock (CS) patients. During extracorporeal membrane oxygenation (ECMO) support, the inflammatory response is intense and complex. It may cause infection, cell damage, organ dysfunction and even death. Hemoperfusion can adsorb inflammatory factors and reduce the inflammatory reaction. CS patients who are likely to receive veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support will be enrolled and randomized with a 1:1 allocation to a simultaneous hemoperfusion arm vs. standard care arm. 1. The patients in the simultaneous hemoperfusion arm will receive hemoperfusion when extracorporeal membrane oxygenation (ECMO) is commenced. 2. The patients in the standard care arm will not receive hemoperfusion when extracorporeal membrane oxygenation (ECMO) is commenced. The primary outcome is the change of plasma interleukin (IL)-6 level after hemoperfusion is commenced.
