Zero‐balance ultrafiltration of the priming blood modifies the priming components and improves the clinical outcome in infants undergoing cardiopulmonary bypass: A randomized controlled trial

Cardiopulmonary bypass (CPB) requirement in infants presents a unique challenge because of the large prime volume-to-blood volume ratio. Packed red blood cells (PRBCs) tend to deteriorate with long-term storage owing to their unphysiological composition and osmolality. Given that blood priming is inevitable in neonates, it is suggested that the metabolic load and osmolality are diminished before CPB initiation. We conducted the present study to...
