文摘

To evaluate whether conversion from aprotinin to epsilon-aminocaproic acid (EACA) during infant cardiac surgery was associated with increased perioperative bleeding.

Design

Structured retrospective chart review.

Setting

University-affiliated large congenital cardiac surgery program.

Measurements

Records from 145 infants (age < 1 yr) receiving aprotinin as antifibrinolytic therapy for cardiac surgery between 6/1/2006 and 12/31/2006 were compared with a cohort of infants receiving EACA for cardiac surgery between 6/1/2008 and 12/31/2008. Sixty-eight infants received aprotinin and 77 infants received EACA. Measured indicators of perioperative bleeding included transfusion volumes, recombinant activated clotting factor VIIa (rFVIIa) administration, need for reexploration, and perioperative chest tube output.

Main Results

EACA treated patients received significantly more rFVIIa for uncontrolled bleeding (19/77 [25%] vs 3/68 [4%]; P < 0.001) and required surgical reexploration more frequently (21/77 [27%] vs 7/68 [10%]; P = 0.01]. Median (25th-75th percentiles) intraoperative platelet transfusion requirements were also increased after the switch to EACA (28 mL [0-58 mL] vs 0 mL [0 mL - 34.5 mL]), but this difference did not reach statistical significance (P = 0.06).

Conclusions

Bleeding in infant cardiac surgery increased following the change in antifibrinolytic therapy from aprotinin to EACA. Given the potential for major harm, especially thrombotic complications, from rFVIIa use, prospective studies examining the safety of postcardiopulmonary bypass rFVIIa administration in infants are necessary before the routine off-label use may be recommended.
