Summary
Our goal is to assess the effects of Tadalafil in the setting of confirmed COVID-19
pneumonia. In particular we plan to assess its effects on oxygen saturation, P:F ratio, and
mixed central venous oxygen
We plan to recruit all hospitalized patients at Santa Barbara Cottage Hospital with a
confirmed COVID19 pneumonia (positive PCR + clinical signs/symptoms of lower respiratory
disease) who meet the Berlin definition of ARDS and have access to measure a mixed venous
oxygen saturation. For the purposes of obtaining mixed central venous oxygen, all
participating patients will already have an internal jugular central venous catheter in place
for inclusion in this study. Since all patients will be intubated, their Legally Authorized
Representative (LAR) will be approached to discuss the study and asked to participate in the
study by an ICU physician, either the attending physician or a medical resident.
Informed consent will be obtained from the LAR by an ICU attending physician or resident
involved in the study prior to participation. Patients who meet the above eligibility
criteria will have baseline levels of mixed central venous oxygen, oxygen saturation, P:F
ratio, blood pressure and PaO2 recorded.
Each patient will then receive Tadalafil 40mg once. The above listed parameters will be
monitored again 30 minutes after drug administration and 4 hours after drug administration.
No other medication or ventilator changes will be made during this time period outside of
emergent changes in the setting of patient deterioration. We will continue to analyze the
data in the event of emergent ventilator changes.
