impact of the different strategies on blood product use was not
assessed as it was beyond the scope of this study.
Only 2.9% of patients received aspirin in the current study,
and the bleeding risk was not assessed because there was no
point-of-care testing. Aspirin has been associated with increased
units of RPC transfused in adult cardiac surgery,
30
but it had no
effect on bleeding and transfusion in paediatric cardiac surgery.
31
The current study was retrospective and depended on the
availability of records and record-keeping by colleagues. The
study did not look at temperature, metabolic state of the patient,
or intra-operative bleeding, which may have contributed to
transfusion rates. The study also did not differentiate between
cyanotic and acyanotic cardiac lesions as data were not clear
on this. Further studies should be conducted to demonstrate
whether there is a relationship between our practice and
morbidity and mortality rates. Transfusion protocols together
with the utilisation of point-of-care testing should be considered.
Conclusion
The use of RPC units was different between RACHS categories,
while maintaining similar haemoglobin levels, despite the absence
of set transfusion triggers and miniature circuits. The pattern of
haemoglobin maintenance was similar to another study. The
transfusion of other blood products was empirical as no point-
of-care tests were utilised. The use of triggers, algorithms and
point-of-care testing in paediatric cardiac patients may result in
a decreased level of transfusion of blood products.
