Abstract:
The purpose of this research was to evaluate and compare two automated blood
processing techniques [Top & Bottom(Optipress®I) and Top & Top (T-ACE II)].
Blood components were separated using 200 TERUFLEX® blood bags for the
T-ACE II technique and 200 Optipac® blood bags for the Optipress®I technique. An
analysis of blood products (FP, red cell:AS-BCR, and LPPCs) in terms their
characteristics was done using CELL DYN 1700 version 1.01, and the efficiency of
blood bag systems and automated blood processing techniques was compared.
Results revealed that T-ACE II showed a statistically significant higher
residual platelet content in the FP bags compared to Optipress®I (18.61+11.21x109
and 14.24+8.58 x109 respectively, p<.001). The red cell:AS-BCR bags prepared
from T-ACE II showed a statistically lower WBC removal compared to Optipress®I
(82.06+8.41% and 77.23+8.40% respectively, p <.001). In the recovery of RBCs,
these was a lower red cell loss from the red cell:AS-BCR bags prepared from
T-ACE II than from Optipress®I (78.31+5.67% and 76.76+8.96% respectively, p
=.04). The LPPCs obtained from BC bags of T-ACE II showed a statistically lower
platelet yields than LPPCs obtained from BC bags of Optipress®I (328.67+ 54.23x109
and 369.93+58.37x109 respectively, p =.001).
In conclusion, T-ACE II demonstrated an improvement in RBC recovery.
Optipress®I improved in WBC removal in red cell:AS-BCR, platelet yields in
LPPCs. However, the quality of blood products from both T-ACE II and
Optipress®I technique were of the same standard.
