Abstract
BACKGROUND: Transfusions in pediatric open heart surgery were analyzed to determine the percentage of patients transfused, the types and volumes of blood components used, and the relationships among transfusions, patient characteristics, surgeon, and surgical procedure. STUDY DESIGN AND METHODS: In a 9-month period, 122 patients, aged 12 or less (median, 1 year; 31% <4 months old), underwent 126 procedures (37 routine, 60 complex, 29 repeat operations). Bypass circuit size and priming solution, target intraoperative hematocrit, heparinization, protamine reversal, and transfusion indications and doses were standardized. The number of full "adult" units of packed red cells (RBCs), units of fresh-frozen plasma (FFP), and platelet concentrates (PCs) transfused in the operating room through postoperative Day 3 were tabulated. RESULTS: RBCs, FFPs, and PCs were transfused in 98, 54, and 58 percent of cases, respectively. Twenty-two percent of components were transfused postoperatively. The average numbers of components transfused for complex procedures (3.4 RBCs, 6.1 total) and repeat operations (4.0 RBCs, 8.1 total) were greater than those for routine procedures (1.8 RBCs, 2.1 total) (p<0.01). The average total number of components transfused did not correlate with surgeon or patient age; patients <4 months old used the largest mean numbers of RBCs and total components of all types. For four procedures, preoperative crossmatch and directed-donation collection orders that would be expected to produce acceptable utilization rates and a <15-percent chance of needing additional components were determined. CONCLUSION: Blood order protocols for pediatric open heart surgery can be procedure-specific, should address the use of non-red cell components, and should cover early postoperative transfusions.
