Accuracy of blood transfusion in postpartum hemorrhage to assess maternal morbidity.
2012
International audience; OBJECTIVE: To measure the accuracy of blood transfusion (timing and number of blood units) in postpartum hemorrhage (PPH) in a perinatal network. STUDY DESIGN: (1) The ANONYMAT software system was used for anonymization and linkage of two large stand-alone databases, the Burgundy Perinatal Network (BPN) and the National Blood Centre (EFS) databases, which contain, respectively, clinical data from hospital discharges and information concerning any blood transfusion in France (considered as the gold standard database for identifying any transfusion). (2) Identification of prescriptions of at least one red blood cell (RBC) unit at the day of delivery (≥22 weeks) and up …
Antibodies to hepatitis B core antigen in blood donors screened for alanine aminotransferase level and hepatitis non-A, non-B in recipients.
1988
Four-hundred and seventeen patients undergoing open-heart surgery were followed for more than 9 months after transfusion. All 2270 blood units transfused had alanine aminotransferase levels less than or equal to 30 U/l. Blood units positive for antibodies to hepatitis B core antigen (anti-HBc) were more frequently associated with recipient hepatitis non-A, non-B (HNANB) (13.7%) than anti-HBc-negative units (4.2%) (p less than 0.001). The frequency of HNANB among recipients of at least 1 anti-HBc-positive blood unit (8/79, 10.1%) was fivefold greater than among recipients of exclusively anti-HBc-negative blood units (7/338, 2.1%) (p less than 0.01). In this study the exclusion of donors posi…
