Vasoactive-Inotropic Score (VIS)

Composite measure of inotropic / vasoactive drug support (Gaies 2010). VIS = dopamine + dobutamine + 100 × (adrenaline + noradrenaline) + 10 × milrinone + 10 000 × vasopressin (µg/kg/min; vasopressin in units/kg/min). Enter 0 for drugs not running. A high maximum VIS after infant cardiac surgery predicts mortality and morbidity.

Score interpretation

VIS < 10 — Low Support 0–9.99

Gaies group 1 (maximum VIS < 10 in the first 24 h).

→ Routine post-op ICU care. Wean inotropes as haemodynamics permit.

VIS 10–14 10–14.99

Gaies group 2.

→ Echocardiography to assess ventricular function; optimise preload, afterload, rhythm, calcium. Consider lactate trend and SvO₂.

VIS 15–19 15–19.99

Gaies group 3.

→ Echocardiography to assess ventricular function; optimise preload, afterload, rhythm, calcium. Consider lactate trend and SvO₂.

VIS 20–24 — High VIS 20–24.99

Gaies group 4: maximum VIS ≥ 20 in the first 24 h after infant cardiac surgery was associated with poor outcome (OR 6.5) and death (Gaies 2014).

→ Senior ICU/cardiac review. Mechanical support (IABP, Impella, V-A ECMO) consideration; aggressive correction of metabolic derangement; surgical re-look if ongoing low cardiac output.

VIS ≥ 25 — High VIS ≥ 25

Gaies group 5 (maximum VIS ≥ 25).

→ ECMO / VAD pathway activation. Transplant centre liaison if appropriate. Family counselling on prognosis.

Interpretation bands for the VIS. Apply clinical judgement and local guidance.
