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.
• Age between 18 and 75 years.
• Patients admitted into ICU and diagnosed as septic shock (sepsis-3.0)13, after adequate fluid resuscitation, high-dose vasoactive drug application \[vasoactive inotropic score (VIS) \> 120\] and conventional therapy together with at least one of the following criteria: (1) sustained hypotension \[mean arterial pressure (MAP) \< 65 mmHg\]; (2) persistent lactacemia (two consecutive values \> 5 mmol/L with at least 30 min interval between samples), with non-decreasing trend on steady doses of inotropes and/or vasopressors; (3) persistent low mixed venous blood oxygen saturation (SvO2) (two consecutive values \< 55% with at least 30 min interval between samples), with non-increasing trend on steady doses of inotropes and/or vasopressors. 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.
• Informed consent provided by the patient or person with decisional responsibility.
