Recruitment & Eligibility

Status
Authorised, recruitment pending
Sex
Not specified
Target Recruitment
390
Inclusion Criteria

Patients aged ≥ 18 years

Vasoplegic shock: patient requiring vasopressor AND with a cardiac index ≥ 2.3/L/min/m² (measured by echocardiography, Swan-Ganz, pulse contour analysis or thermodilution) AND with hyperlactatemia > 2 mmol/l.

Refractory shock: dose of vasopressor (express as norepinephrine base equivalent) ≥ 0.25 µg/kg/min in order to maintain perfusion pressure within patient-defined targets

Early intervention: Criteria for refractory AND vasoplegic shock reached for less than 12 hours.

Informed consent obtained from the patient or, if unable to give consent, a surrogate. If the surrogate is not available, emergency consent can be considered.

Covered by French national health insurance

Vasoplegia must be primarily caused by one of the following etiologies: - Sepsis (documented or clinically suspected infection) - Post-operative vasoplegia (following cardiac or non-cardiac surgery) - Post hemorrhage - Sterile systemic inflammation (e.g., pancreatitis, burns, trauma) - Anaphylaxis - Liver failure - Other causes of vasoplegia

Exclusion Criteria

Patients that do not present the criteria for vasoplegic AND refractory shock at the time of inclusion anymore (resolved condition)

Patient already enrolled in an interventional trial

Decision to limit life-sustaining treatments

under legal protection

Pregnant, parturient or breastfeeding women

Ongoing vasopressin treatment

Ongoing inotrope treatment (except norepinephrine)

Ongoing acute coronary syndrome, mesenteric ischemia

Uncontrolled active bleeding

Vasoplegia due to neurogenic shock

Vasospastic disease (Raynaud's disease, systemic scleroderma, …)

Hyponatremia <120 mmol l-1

Known hypersensitivity to Argipressin or to any of the excipients of REVERPLEG®

Primary Outcome Measures
NameTimeMethod
Composite score including 3 criterions ordered from most to the least important: -mortality at D30 -use of renal replacement therapy (RRT) within 30 days post-inclusion -persistance of vasopressor use within 15 days post-inclusion. The score is calculated by comparing each patient from one group to all patients from the other group in the concerned strata (stratified win-ratio analysis).
