Insights

High-dose aprotinin did not reduce the inflammatory response in children undergoing extracorporeal circulation (ECC). This study found no clinical or biochemical benefits of using aprotinin for managing systemic inflammation post-ECC.

Area of Science:

  • Pediatric Cardiac Surgery
  • Cardiopulmonary Bypass
  • Inflammatory Response

Background:

  • Extracorporeal circulation (ECC) can trigger a systemic inflammatory response in pediatric patients.
  • Aprotinin, a hemostatic agent, has been investigated for its potential anti-inflammatory effects during ECC.

Purpose of the Study:

  • To determine if high-dose aprotinin administration reduces the inflammatory process in children following ECC.
  • To assess the impact of aprotinin on clinical and biochemical markers of inflammation.

Main Methods:

  • Prospective randomized study involving children aged 30 days to 4 years undergoing congenital heart disease correction with ECC.
  • Two groups: Control (n=9) and Aprotinin (n=10), with aprotinin administered before and during ECC.
  • Analysis of systemic inflammatory response, hemostasis, and multiorgan dysfunction using clinical and biochemical markers.

Main Results:

  • Demographic and intraoperative variables were similar between groups, with greater hemodilution in the Aprotinin group.
  • Aprotinin showed no significant benefit in reducing mechanical pulmonary ventilation time, postoperative ICU stay, or length of hospital stay.
  • No significant reduction in clinical manifestations or serum markers of the inflammatory systemic response was observed.

Conclusions:

  • Hemostatic high-dose aprotinin did not effectively minimize clinical or biochemical indicators of the inflammatory systemic response in this pediatric cohort undergoing ECC.
  • The findings suggest that aprotinin is not beneficial for managing post-ECC inflammation in this patient population.
