Objectives
Narrative objectives1
Infants and neonates have smaller size of circulatory blood volume with respect to the cardiopulmonary bypass (CPB) circuits. Thus, marked hemodilution and decrease in platelet count and plasma concentration of fibrinogen occurs during cardiopulmonary bypass in cardiac surgeries for infants and neonates. Although transfusion of platelets and fresh frozen plasma (FFP) is required to normalize the platelet count and fibrinogen levels, the most pediatric patients cannot output enough urine volume with respect to the transfused volume. Therefore, transfusion of platelets and FFP following the completion of the CPB should be performed during modified ultrafiltration (MUF) period to eliminate excess water derived from the blood products.
The prediction formula for elevation values of platelet count and fibrinogen levels with transfusion of platelets and FFP during MUF is not yet established. We studied in the past postoperative values of platelet count and fibrinogen levels of infants and neonates who underwent transfusion of platelets and/or FFP during MUF. The study showed that the postoperative values have large variance and are lower than the predictive values: pre MUF values added predictive elevation values calculated from transfused volume of blood products, patient circulatory blood volume, CPB volume and MUF circuit volume. Our primary aim for this following study is to examine whether the platelet count and fibrinogen levels at cessation of transfusion of platelets and FFP during MUF, not at the time point on admission of postoperative care unit, are approximately equal to the prediction values calculated from our prediction formula or not. Our second aim for the study is to elucidate parameters and factors to cause dissociation variance of the actual measurement values from the predictive values.
We also examine the beneficial effect of FFP transfusion during CPB.
