Overview and Limitations of Database Research in Anesthesiology: A Narrative Review.

The utilization of large-scale databases for research in medical fields, including anesthesiology, has increased in popularity over the last decade, likely due to their structured content and relative ease of access. These databases have been used in a variety of perioperative studies, including analyses of risk stratification, preoperative testing, complications, and cost. While these databases contain a wealth of information that allows for an abundance of research opportunities, there are unique limitations to their use.

Differential Ventilation Using Flow Control Valves as a Potential Bridge to Full Ventilatory Support during the COVID-19 Crisis.

Background: During the COVID-19 pandemic, ventilator sharing was suggested to increase availability of mechanical ventilation. The safety and feasibility of ventilator sharing is unknown.

Methods: A single ventilator in pressure control mode was used with flow control valves to simultaneously ventilate two patients with different lung compliances.
