Behandlung von ARDS mit instilliertem T3 (ARDS+T3)
Randomisierte Phase-II-Intervention versus Nicht-Intervention, multizentrische Studie zu den Auswirkungen von Schilddrüsenhormon (T3) auf das extravaskuläre Lungenwasser (EVLW) bei Patienten mit akutem Atemnotsyndrom (ARDS)
It is hypothesized that instillation of Liothyronine Sodium (T3) into the airspace will be safe, well tolerated, and will increase alveolar fluid clearance and decrease inflammation in patients with ARDS, reflected in improved oxygenation index (OI) and oxygenation saturation index (OSI).

Detaillierte Beschreibung
T3 Therapy in ARDS- Phase 2 Randomized, Unblinded, Intervention versus Non- Intervention Trial. Enrollment 68 participants (50 treatment + 18 control). Purpose- To determine the safety and tolerability of T3 delivery into the lungs of ARDS patients, and to measure the effect of T3 on Oxygenation in ARDS patients. Study Drug- Liothyronine Sodium (T3), 50 mcg will be instilled twice daily via a catheter through the ETT into the airway in a total volume of 10 mL (T3+0.9% sodium chloride), over 5 days (10 total doses), or until extubation, whichever comes first.

Oxygenation: Oxygenation Index (OI), and/or Oxygenation Saturation Index (OSI).
Zeitfenster: baseline
|
To assess the efficacy of airway instilled T3 improving oxygenation by reducing OI and OSI in ARDS patients. OI will be measured by mechanical ventilator (FIO2 and Mean Airway Pressure, MAP), and ABG (PaO2). OSI will be measured by mechanical ventilator (FIO2, SpO2 and MAP): OI = (FIO2 x MAP / PaO2). OSI = (FIO2 x MAP / SpO2). |
