Objective: The effects of Vasoactive-Ventilation-Renal (VVR) score on the evaluation of pediatric heart surgery results were investigated in this study.
Methods: This retrospective study included children younger than 18 years of age who were operated for congenital heart disease between was July 1st- December 31st 2018. Patients who needed ECMO support at the first postoperative 72 hours were not included in the study group. The postoperative initial, 24th and 48th-hour Vasoactive-Inotrope Score (VIS) and VVR scores of all patients were calculated in the intensive care unit (ICU). The effects of these scores on lengthy ICU duration (PCILOS, duration more than the upper 25th percentile) and to the hospital mortality (before 30 days) were evaluated.
Results: There were 340 patients in this study. The median age was 12 months (1 day-18 years), and the median weight was 7 kg (2.5 -82 kg). 18% of the patients had single ventricle physiology. Total correction was performed in 88% of the patients. Median RACHS 1 score was 2 (1-6). PCILOS was>112 hours and total mortality was 4%. The 0th hour VVR ICU c index=0.73 (CI: 0.70-0.77), mortality c index=0.77 (CI: 0.69-0.85). VVR at 24th hour ICU c index=0.75 (CI: 0.71-0.79), mortality c index=0.86 (CI: 0.81-0.91). VVR at 48th-hour ICU c index=0.87 (CI: 0.82-0.92), mortality c index=0.92 (CI: 0.87-0.97). The VVR score at 48th-hour was a strong indicator for the prediction of both LICU duration (odds ratio [OR]: -1.44; p=0.001) and hospital mortality (OR: -1.28; p=0.001).
Conclusion: The postoperative VVR score can be a strong determinant for the prediction of early clinical results in congenital heart disease patients, which were considerably a heterogeneous group.
