Official title
Nitric Oxide Gas Inhalation Therapy for Mechanically Ventilated Patients With Severe Acute Respiratory Syndrome Caused by SARS-CoV2: a Randomized Clinical Trial.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Severe acute respiratory syndrome (SARS-CoV2) due to novel Coronavirus (2019-nCoV) related infection (COVID-19) is characterized by severe ventilation perfusion mismatch leading to refractory hypoxemia. To date, there is no specific treatment available for 2019-nCoV. Nitric oxide is a selective pulmonary vasodilator gas used in as a rescue therapy in refractory hypoxemia due to acute respiratory distress syndrome (ARDS). In-vitro and clinical evidence indicate that inhaled nitric oxide gas (iNO) has also antiviral activity against other strains of coronavirus. The primary aim of this study is to determine whether inhaled NO improves oxygenation in patients with hypoxic SARS-CoV2. This is a multicenter single-blinded randomized controlled trial with 1:1 individual allocation
