Overview :
Certain patients undergoing total joint arthroplasty
procedures have a very low chance of receiving a blood transfusion in the
perioperative period. These patients may not need to donate autologous blood.
Rationale:
(1) The
National Heart, Lung and Blood Institute Expert Panel on the Use of Autologous
Blood has recommended that patients with < 10% chance of needing a
perioperative transfusion should not be encouraged to donate autologous blood.
(2) A large
percentage (56% of units in the study population) of the autologous products
are discarded.
Factors with an
increased risk for blood transfusion:
(1) revision
knee or hip procedure
(2) one-stage
bilateral primary knee replacement
(3) initial
hemoglobin < 130 g/L
(4) age >=
65
Groups with Very Low
Chance of Perioperative Transfusion
Group 1:
(1) hemoglobin >= 150 g/L
(2) unilateral primary arthroplasty
Group 2:
(1) hemoglobin 130 – 150 g/L
(2) age < 65 years of age
(3) unilateral primary arthroplasty
NOTE: These findings are similar to those described above in
05.01.02.
