Red Cell Transfusion

Refer to the Haematology specific procedure 5056 Verbal Orders for Platelets and Red Blood Cell Transfusions for Haematology Patients.

Blood Filters

The standard in-line blood filters (first generation filters) used for most blood transfusions work as simple sieves. The mesh of these filters varies but is commonly 170 micron. Blood is now leucodepleted at source and therefore second and third generation filters are no longer required for haematology patients.

Leucodepletion

CMV Negative Blood

Within NZBS all donor products are now leucodepleted at source, which is deemed sufficient to limit CMV exposure via blood products.

Refer to the NZBS clinical guideline: NZBS Policy on the Provision of CMV Antibody Negative Blood Components (111P067)

See also the CDHB Blood and Blood Product Policy.

Irradiated Blood

See NZBS Transfusion Medicine Handbook.
