Effects of Balanced Ultrafiltration During Extracorporeal Circulation for Children with Congenital Heart Disease on Postoperative Serum Inflammatory Response.

Objectives

We studied inflammatory marker changes with ultrafiltration extracorporeal techniques and compared these levels to those occurring during conventional techniques.

Methods

Seventy-four children undergoing extracorporeal circulation during congenital heart surgery were divided into two groups-conventional (control) and balanced ultrafiltrations (study). Serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and soluble intercellular adhesion molecule-1 (sICAM-1), static lung compliance (Cstat), alveolar-arterial oxygen partial pressure difference (A-aDO2), and oxygenation index (OI) were measured.

Results

Thirty minutes after extracorporeal circulation (T1), IL-6 and TNF-α levels significantly increased (p < .05), which plummeted 3 h after surgery (T2). The levels in the study group were lower (p < .05). sICAM-1 levels at T1 and T2 significantly exceeded those at T0, and study group had lower levels (p < .05). At T1, Cstat and OI dropped (p < .05), which increased at T2 (p < .05), and study group had less decreases (p < .05). A-aDO2 at T1 surpassed that before intervention (p < .05), and study group had less increase (p < .05).

Conclusion

Balanced ultrafiltration exerts protective effects on children with congenital heart disease undergoing extracorporeal circulation.
