Zero-Balance Ultrafiltration of Priming Blood Attenuates Procalcitonin and Improves the Respiratory Function in Infants After Cardiopulmonary Bypass: A Randomized Controlled Trial.
Blood priming is needed for cardiopulmonary bypass (CPB) in neonates and infants to avoid exceeding hemodilution; however, transfusion-related inflammation affects post-CPB outcomes in infant open-heart surgery. Procalcitonin, a newly detected inflammatory moderator and a sensitive parameter for predicting pulmonary dysfunction secondary to CPB, rises after CPB. We hypothesized that the hemofiltration of priming blood before CPB might decrease inflammatory mediators in the blood and post-CPB inflammatory replications, thereby improving the respiratory function after CPB in infants. ⋯ The time to extubation and the ICU stay were shorter in the Z-BUF Group (P < 0.05). A positive correlation was found between the peak procalcitonin concentration and the time to extubation directly and pulmonary compliance reversely. These results suggest that the Z-BUF of priming blood may have some beneficial clinical effects such as improved respiratory function and attenuated procalcitonin.
