Randomized Controlled Trial
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. ⋯ The Z-BUF group showed significant reductions in postoperative blood loss; postoperative blood transfusion; time to extubation; the length of stay in the ICU; the levels of lactate, sodium, and blood urea nitrogen at 24 hours postoperatively and the body temperature at 18 hours postoperatively (P < .05). However, no statistically significant differences were found between the 2 groups regarding the body temperature and the levels of serum creatinine and blood urea nitrogen after admission to the ICU. The results of the present study demonstrated that the Z-BUF of the priming blood could be a useful strategy in infants undergoing CPB insofar as it significantly modified the composition of the priming blood and improved the clinical outcome among our patients.
