Background: The use of aprotinin in children undergoing cardiopulmonary bypass is controversial. We hypothesized that aprotinin would reduce blood product use and operative closure time in selected pediatric patients. Methods: For a 6-month period starting in October 1999, consecutive cardiopulmonary bypass patients 6 months of age or less (n = 18) or having a repeat sternotomy (n = 18) received aprotinin. Similar consecutive patients from the preceding 6 months served as controls (n = 35 and 41, respectively). Data extracted from medical records included preoperative clinical characteristics, operative and postoperative procedures, and total blood product use. Results: Patients in the aprotinin and control groups were well matched with regard to preoperative and intraoperative variables. Patients 6 months of age or less who received aprotinin required less operative closure time when compared with controls (median, 93 vs 127 minutes, p = 0.004), and trended toward requiring fewer red blood cell unit exposures (median, three vs five exposures, p = 0.07). Patients undergoing repeat sternotomy who received aprotinin required less operative closure time when compared with controls (mean, 126 vs 159 minutes, p = 0.007), fewer red blood cell unit exposures (median three vs four exposures, p = 0.002), and fewer fresh-frozen plasma unit exposures (median, zero vs one exposure, p = 0.007). Conclusions: Aprotinin reduced operative closure time and blood product exposure in pediatric patients undergoing cardiopulmonary bypass who were 6 months of age or less or underwent a repeat sternotomy.
