VIS score stands for Vasoactive-Inotropic Score. It is a numerical scoring system used in pediatric intensive care to quantify the amount of vasoactive and inotropic medications a child is receiving during shock management. This score helps medical teams measure the severity of shock and assess the intensity of treatment required to maintain stable blood pressure and heart function.
The VIS score is calculated using a specific formula that combines different vasoactive medications. The formula includes dopamine plus dobutamine plus one hundred times epinephrine plus one hundred times norepinephrine plus ten times milrinone plus ten thousand times vasopressin. All doses are measured in micrograms per kilogram per minute, except vasopressin which is in units per kilogram per minute. For example, if a child receives dopamine at 5 and epinephrine at 0.1, the VIS score would be 5 plus 100 times 0.1, which equals 15.
The VIS score is interpreted based on specific ranges that indicate shock severity. A VIS score of 0 to 15 indicates mild shock, 16 to 30 represents moderate shock, 31 to 45 shows severe shock, and scores above 45 indicate critical shock. The clinical significance is substantial - higher VIS scores correlate with more severe shock states, predict mortality risk, guide treatment intensity decisions, and help monitor patient response to therapy over time.
The VIS score has several important clinical applications in pediatric intensive care. First, it serves as a powerful tool for outcome prediction, helping assess mortality risk, predict length of ICU stay, and evaluate organ dysfunction severity. Second, it enables effective treatment monitoring by tracking patient response to therapy, guiding medication weaning decisions, and assessing improvement trends over time. Third, the VIS score has valuable research applications, allowing comparison of different treatment protocols, standardization of shock severity across studies, and evaluation of new therapeutic interventions.
To summarize what we have learned about VIS score in pediatric shock management: The VIS score is a valuable tool that quantifies the amount of vasoactive support a child requires during shock. It uses a standardized calculation formula incorporating various medications. Higher VIS scores indicate more severe shock states and are associated with worse clinical outcomes. This scoring system serves as an essential tool for monitoring treatment response and predicting patient prognosis in pediatric intensive care settings.
