ExtraCorporeal Membrane Oxygenation in the Therapy for REfractory Septic Shock With Cardiac Function Under Estimated (ECMO-RESCUE)

February 19, 2024 updated by: Second Affiliated Hospital of Guangzhou Medical University

ExtraCorporeal Membrane Oxygenation in the Therapy for REfractory Septic Shock With Cardiac Function Under Estimated (ECMO-RESCUE): a Prospective, Multicenter, Non-randomized Cohort Study

The ECMO-RESCUE study is a prospective, multicenter, non-randomized, cohort study. In this study, we aimed to assessed whether VA-ECMO treatment can improve the 30-day survival rate of patients with sepsis-induced refractory cardiogenic shock.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All patients who meet inclusion criteria and have no exclusion criteria are considered to be enrolled. During the period of study, the participants can decide whether to accept ECMO based on their personal conditions. If a patient is willing to accept ECMO treatment, we initiate VA-ECMO within 6 hours. Participants taking VA-ECMO during the period of study are referred to as cohort 1, and patients receiving only conventional therapy without ECMO belong to cohort 2. 30-day survival will be accessed to evaluate the survival benefit from ECMO therapy for sepsis-induced refractory cardiogenic shock.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

The above condition lasts more than 5 hours.
  • Rapidly deteriorating sepsis-induced myocardial impairment is defined by at least one of the following criteria: (1) rapidly deteriorating ventricular function (LVEF < 35%); (2) cardiac index (CI) < 2L/min/m2 (> 3 hr); (3) emerging refractory arrhythmia.

  • Prolonged cardiac arrest (> 30 min) before ECMO, or CPR survivors remaining comatose.
  • Irreversible condition or meet the inclusion criteria for more than 12 hr.

  • Peripheral artery disease disabling insertion of outflow cannula to femoral artery.
  • Irreversible neurological pathology

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: cohort 1
Participants taking VA-ECMO during the period of study are referred to as cohort 1
Procedure: Extracorporeal Membrane Oxygenation (ECMO)
All patients in cohort 1 will initiate ECMO as fast as possible. A maximum of 6 hours is allowed between enrollment and the actual initiation of ECMO. ECMO catheterization and management will be operated by an experienced ECMO team and carried out at the bedside. VA or VAV mode will be chosen according to the patient's condition.
No Intervention: cohort 2
Patients receiving only conventional therapy without ECMO belong to cohort 2
