Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Transfusion of packed red blood cells is a common procedure in critically ill patients. In recent years it has been shown that for many patient populations a restrictive transfusion strategy is not inferior compared to a liberal transfusion strategy with regard to overall outcome.

So far it is unclear whether patients with an ARDS should receive blood transfusions according to a restrictive or liberal transfusion strategy. Besides pulmonary gar exchange and cardiac output, the hemoglobin concentration is an important determinant for oxygen delivery.

The aim of this retrospective observational study is to analyze if low levels of hemoglobin/a restrictive transfusion strategy and are associated with a different mortality compared to higher levels of hemoglobin/a liberal transfusion strategy in patients with an ARDS.

Blood transfusion

Observational post-ad-hoc design to compare patients admitted with an ARDS and separated into different groups according to their mean hemoglobin concentration during their stay on the intensive care unit.

Approximately 1000 adult patients admitted from 2007 to 2018 to the Charite ARDS center will be enrolled in the study. They are followed up until their discharge from the ICU.
