Metoprolol in Acute Respiratory Distress Syndrome (MAIDEN) (MAIDEN)
Acute Respiratory Distress Syndrome (ARDS)
About this trial
This is an interventional treatment trial for Acute Respiratory Distress Syndrome (ARDS) focused on measuring metoprolol, beta-blockers, sepsis, orotracheal intubation, Pathologic Processes, Respiratory Disease, Neutrophil Extracellular Traps, platelet aggregation, diffuse alveolar damage, neutrophil infiltration, Pulmonary Inflammation, pancreatitis, Severe Acute Respiratory Syndrome-Corona Virus-2, Drug-Related Side Effects and Adverse Reactions
Eligibility Criteria
Inclusion Criteria: Patients (≥18 years and <80 years) with a clinical diagnosis of ARDS of any aetiology (pneumonia, including SARS-CoV-2, sepsis, pancreatitis, bronchospasm and trauma) admitted to the ICU. Orotracheal intubation (OTI) and mechanical ventilation within 72 hours prior to randomisation. Moderate-severe ARDS (PaO2/FiO2: ≤200 mmHg under standardised conditions (PEEP≥5 cm H2O). Heart rate ≥ 60 bpm. Invasive systolic blood pressure ≥ 110 mmHg. Exclusion Criteria: Prolonged hospital admission prior to randomisation (i.e. ≥7 days at the time of randomisation). Reduced left ventricular ejection fraction (LVEF <50%). Life expectancy due to other processes (cancer, degenerative diseases, etc.) of less than 6 months. Right ventricular (RV) systolic dysfunction. Concomitant acute heart failure (cardiac index ≤2.5 L/m2 or pulmonary capillary pressure ≥15 mmHg or clinical suspicion). Second-degree atrioventricular (AV) block, 2:1 AV block, high-grade/advanced AV block and third-degree AV block. Also significant sinus bradycardia, which would be implied by having a heart rate >60 bpm as an inclusion criterion. Pregnant or breastfeeding women. Cardiogenic shock. Persistent invasive blood pressure <110 mmHg despite vasopressor agents. Use of noradrenaline at concentrations greater than 0.2 µg/kg/min at the time of the randomisation. Use of dobutamine within 48 hours before randomisation. Concomitant pulmonary embolism. Known severe peripheral arterial disease. Known asthma before admission (with active bronchodilator therapy). Active beta-blocker treatment prior to admission (i.e. within 3 months prior to admission).
