Bloodless Arterial Switch Operation in a 2.7-kg Jehovah's Witness Patient.

Bloodless pediatric cardiac surgery requiring the use of cardiopulmonary bypass (CPB) remains a challenge for the entire operating room (OR) team. The amount of circulating blood volume to pump prime volume mismatch of small patients results in hemodilution that frequently results in transfusion of allogeneic blood products. Patients of families of the Jehovah's Witness (JW) faith reject the use of these products because of religious beliefs.

Albumin priming improves the efficiency of the Minntech HPH Jr. hemoconcentrator.

The desired use of the HPH Jr. is optimal due to the low priming volume; however, the lower rate of volume removal necessitates utilization of a larger hemofilter. Larger hemofilters carry a higher prime volume, which is impactful in the pediatric setting.
