Effect of the application of the "Patient blood management" programme on the approach to elective hip and knee arthroplasties.

Background And Objectives: The "Patient Blood Management" (PBM) programmes have demonstrated their value in the continuous improvement of care practice, due to continuous systematic reviewing of results and their dynamic and multidisciplinary updating in accordance with new clinical evidence. Our goal is to demonstrate the effectiveness of simple protocols, applicable in second level hospitals.

Patients And Methods: 702 patients undergoing scheduled arthroplasty from 2011 to 2018 were retrospectively analysed.

Transfusion of D positive red cells to selected D-negative patients.

Background: To transfuse packed red blood cells isogroup ABO D is a usual transfusion practice. However, when there is not enough D negative blood available, we can transfuse positive red blood cells to negative patients. Immunocompetent D negative individuals may develop serologically detectable anti-D antibodies within 3 months after exposure to D positive red blood cells.
