Inclusion criteria

Inclusion criteria: Pediatric patients who underwent intracardiac repair for ventricular septal defect or atrial septal defect at Seirei Hamamatsu Hospital between January 2006 and December 2024.

Exclusion criteria

Exclusion criteria: Cases where no transfusion surgery was deemed unfeasible and blood products were administered to the initial priming fluid of cardiopulmonary bypass beforehand Cases extracted from the database as ventricular septal defect and atrial septal defect, but where these were comorbid conditions and the primary pathology differed Cases where the surgical procedure was extended during surgery due to unexpected patient factors or complications Cases meeting the age criteria of 0 to 15 years old but with a weight exceeding 50 kg Cases where a lateral thoracotomy approach was chosen instead of a standard median sternotomy Emergency surgeries

Design outcomes

Primary

MeasureTime frame
To demonstrate the correlation between the intra-circuit blood replacement ratio in RAP & RP and hematocrit changes.

Secondary

MeasureTime frame
To confirm whether there is a difference in the proportion of blood replaced within the circuit when patients are divided into a no-transfusion group and a group receiving transfusions. To confirm whether there is a difference in the changes in local cerebral oxygen saturation and lactate levels between the group undergoing RAP and the group not undergoing RAP. To confirm whether there is a difference in ICU length of stay and hospital length of stay between the group undergoing RAP and the group not undergoing RAP.
