Abstract
- Background: This study focuses on biomarkers in infants after open heart surgery, and examines the association of high‐sensitive troponin T (hs‐cTnT), interleukin‐6 (IL‐6), and interleukin‐8 (IL‐8) with postoperative acute kidney injury (AKI), ventilatory support time and need of vasoactive drugs. Methods: Secondary exploratory study from a double‐blinded clinical randomized trial (Mile‐1) on 70 infants undergoing open heart surgery with cardiopulmonary bypass (CPB). In this sub‐study, the entire study population was examined without considering the study drugs. The biomarkers' peak concentration (highest concentration at 2 or 6 h post‐CPB) were used for statistical analyses. Results: Peak IL‐8, hs‐cTnT, and IL‐6 occurred at 2 h post‐CPB for 96%, 79%, and 63% of the patients, respectively. The odds ratio of developing AKI2‐3 for IL‐6 > 293 pg/mL was 23.4 (95% CI 5.3;104.0), for IL‐8 > 100 pg/mL it was 11.5 (3.0;44.2), and for hs‐cTnT >5597 pg/mL it was 6.1 (1.5; 24.5). In more than two third of the patients with the highest peak concentrations of IL‐8, IL‐6, and hs‐cTnT, there was a need for ventilatory support for >24 h and use of vasoactive drugs at 24 h post‐CPB, while in less than one third of the patients with the lowest peak concentrations of IL‐8 and hs‐cTnT such requirements were observed. Conclusions: The peak biomarker concentrations and CPB‐time strongly predicted AKI2‐3, with IL‐6 and IL‐8 emerging as strongest predictors. Furthermore, our findings suggest that measuring hs‐cTnT and IL‐8 just 2 h post‐CPB‐weaning may assist in identifying infants suitable for early extubation and highlight those at risk of prolonged ventilation.
