Table 3.
Postoperative vasoactive-inotropic score (VIS) and left ventricular ejection fraction (LVEF) of the patients in the two groups.
| Con group (n = 28) | DEX group (n = 29) | P value | |
|---|---|---|---|
| VIS (μg/kg/min) | |||
| Postoperative 2 h | 6.18 ± 3.57 | 4.88 ± .3.28 | 0.158 |
| Postoperative 6 h | 5.20 ± 3.24 | 3.34 ± 1.20 | 0.006 |
| LVEF (%) | |||
| Postoperative 24 h | 58.18 ± 5.81 | 57.00 ± 5.10 | 0.419 |
Quantitative data are presented as means ± standard deviations. VIS: vasoactive‐inotropic drug score = dopamine (μg/kg/min)∗1 + dobutamine (μg/kg/min)∗1 + milrinone (μg/kg/min)∗10 + adrenaline (μg/kg/min)∗100 + norepinephrine (μg/kg/min)∗100 + pituitrin (units/kg/min)∗1000; h: hour.
