Core Tip

Core Tip: In this retrospective study at two tertiary academic medical centers during the initial coronavirus disease 2019 surge, we examine trends in ventilator mechanics and outcomes of 114 acute respiratory distress syndrome (ARDS) patients receiving three adjunct therapies (prone positioning, neuromuscular blockade and inhaled vasodilations). We found a significant improvement in arterial oxygen partial pressure/fractional inspired oxygen ratio with the addition of inhaled vasodilators while proning and in lung compliance with the addition of continuous neuromuscular blockade among others. Our groups were not large enough to detect a difference in mortality or length of stay. However, this study provides a large amount of data and multi-day trends to further our understanding of the physiologic response to multiple adjunct therapies for ARDS in combination.
