Cell saving systems do not reduce the need of transfusion in low-risk patients undergoing cardiac surgery.

Objectives: Cell saving systems have been widely used to reduce blood loss and need of transfusions. These device are mainly indicated in complex cardiac surgery procedures and in those patients with a high risk of bleeding. However, it is not clear if there is a benefit of a cell saver (CS) system in low-risk patients undergoing cardiac surgery.

[Bloodless cardiac surgery in Jehovah's witnesses: outcomes compared with a control group].

Introduction And Objectives: Some patients, such as Jehovah's Witnesses, refuse to use blood products, which can make it difficult to achieve the same outcomes as in the general population. The objective of this study was to determine whether clinical characteristics and surgical outcomes in Jehovah's Witnesses undergoing cardiac surgery are similar to those in other patients.

Methods: Paired-group retrospective cohort study.
