Vasoactive-Inotropic Score and Vasoactive-Ventilation-Renal Score as Outcome Predictors for Children on Extracorporeal Membrane Oxygenation

We aimed to determine the association of vasoactive-inotropic score (VIS) and vasoactive-ventilation-renal (VVR) score with in-hospital mortality and functional outcomes at discharge of children who receive ECMO. A sub-analysis of the multicenter, prospectively collected data by the Collaborative Pediatric Critical Care Research Network (CPCCRN) for Bleeding and Thrombosis on ECMO (BATE database) was conducted. Of the 514 patients who received ECMO across eight centers from December 2012 to February 2016, 421 were included in the analysis. Patients > 18 years of age, patients placed on ECMO directly from cardiopulmonary bypass or as an exit procedure, or patients with an invalid or missing VIS score were excluded. Higher VIS (OR = 1.008, 95% CI: 1.002–1.014, p = 0.011) and VVR (OR: 1.006, 95% CI: 1.001–1.012, p = 0.023) were associated with increased mortality. VIS was associated with worse Pediatric Cerebral Performance Category (PCPC) (OR = 1.027, 95% CI: 1.010–1.044, p = 0.002) and Pediatric Overall Performance Category (POPC) score (OR = 1.023, 95% CI: 1.009–1.038, p = 0.002) at discharge. No association was found between VIS or VVR and Functional Status Score (FSS) at discharge. Using multivariable analyses, controlling for ECMO mode, ECMO location, ECMO indication, primary diagnosis, and chronic diagnosis, extremely high VIS and VVR were still associated with increased mortality.

A Vasoactive Inotropic Score Predicts the Severity of Hypotensive Shock and Mortality in Preterm Infants

Objective: To validate the prediction of the severity of hypotensive shock and mortality using the vasoactive inotropic score in preterm infants.Methods: In this retrospective study we calculated the vasoactive inotropic score (VIS) and cumulative exposure to cardiovascular medications over time (VISct) in a cohort of preterm infants with hypotensive shock who received a cardiovascular support. Receiver operator curve was constructed to predict the primary outcome which was death due to hypotensive shock. Results: VIS had an area under the curve of 0.73 (95% CI 0.85-0.98, p < 0.001). A VIS cut off of 25 has sensitivity and specificity of 66% and 92%, and positive and negative predictive values of 78.5% and 83%, respectively.Conclusion: High VIS predicts high mortality rate due to irreversible shock in preterm infants

Impact of CRRT in Patients with PARDS Treated with VV-ECMO

The high mortality of pediatric acute respiratory distress syndrome (PARDS) is partly related to fluid overload. Extracorporeal membrane oxygenation (ECMO) is used to treat pediatric patients with severe PARDS, but can result in acute kidney injury (AKI) and worsening fluid overload. The objective of this study was to determine whether the addition of CRRT to ECMO in patients with PARDS is associated with increased mortality. Methods: We conducted a retrospective 7-year study of patients with PARDS requiring ECMO and divided them into those requiring CRRT and those not requiring CRRT. We calculated severity of illness scores, the amount of blood products administered to both groups, and determined the impact of CRRT on mortality and morbidity. Results: We found no significant difference in severity of illness scores except the vasoactive inotropic score (VIS, 45 ± 71 vs. 139 ± 251, p = 0.042), which was significantly elevated during the initiation and the first three days of ECMO. CRRT was associated with an increase in the use of blood products and noradrenaline (p < 0.01) without changing ECMO duration, length of PICU stay or mortality. Conclusion: The addition of CRRT to ECMO is associated with a greater consumption of blood products but no increase in mortality.

Vasoactive-inotropic Score for Early Detection and Mortality Prediction of Sepsis in Children

BACKGROUND: Early detection and treatment of sepsis can prevent septic shock and reduce mortality rate. Troponin can become a prognostic factor in sepsis. However, not all health facilities are equipped to assess troponin levels. Vasoactive-inotropic score (VIS) is a simpler and more accessible method to describe hemodynamic status. The aim of this study was to assess the suitability of VIS score as early prognosis and mortality predictor of sepsisMETHODS: A retrospective study was conducted to determine the correlation between VIS and troponin levels for sepsis cases in Pediatric Intensive Care Unity (PICU) Haji Adam Malik Hospital, Medan from January 2018 to December 2019. VIS score at 48 hours, maximum VIS score, pediatric logistic organ dysfunction-2 (PELOD-2) score, cardiac troponin levels at 48 hours were taken from medical records.RESULTS: There were 54 samples analyzed. VIS scores were positively correlated (p<0.001) to troponin T and troponin I levels at 48 hours (r=0.670 and r=0.606, respectively). VIS at 48 hours and maximum VIS were related to mortality (p=0.001 and p<0.001, respectively). VIS score at 48 hours could be used as a predictive factor for mortality (area under the curve (AUC): 79.7%, p<0.001) with a cut-off point at 11 (74.4% sensitivity and 80% specificity). High VIS at 48 hours indicated poor outcomes of sepsis in children with odd ratio (OR) value: 1.99 (95% confidence interval (CI): 1.25-3.19).CONCLUSION: Vasoactive-inotropic score was suitable as an alternative to cardiac troponin T and troponin I levels at 48 hours to early detect myocardial dysfunctions and mortality in children.KEYWORDS: troponin, vasoactive-inotropic score, sepsis, children, mortality
