对疾病严重程度及预后有较好的预判作用;其值越大

Abstract
Objective:To determine the association between vasoactive support and clinical outcome in infants after cardiac surgery.Methods:A retrospective chart review of 53 children(<6months of age) undergoing cardiac surgery with bypass was conducted. Vasoactive-inotropic scores(VIS) were calculated during the first 48 postoperative hours
and the maximum(MAX)and mean(MEA)scores in the first and second 24 postoperative hours[VIS(24MAX)
VIS(24MEA)
VIS(48MAX)
VIS(48MEA)] were also recorded. Chi-test
t-test
and ROC curves were performed for the association between VIS and the clinical outcomes. Results :There were 6 cases of neonates(6/53
11.32%)
11 cases of complex congenital heart disease eliminated(atrial septal defect
ASD)and ventricular septal defect(VSD)(11/53
20.75%)[1 case of complete atrioventricular septal defect(CAVC)
1 case of double outlet of right ventricle(DORV)
6 cases of translocation of great arteries(TGA)
1 case of pulmonary valve atresia(PVA)
2 cases of total anomalous pulmonary venous connection(TAPVC)]
3 cases of death(3/53
5.66%). Children who reached poor outcomes included 5 cases of neurologic injury(5/53
9.43%)
5 cases of cardio-pulmonary resuscitation(5/53
9.43%)and 4 cases of hemodialysis(4/53
7.56%). ROC analysis indicated that the VIS(24MAX) was strongly associated with poor outcomes and death(AUROC =0.938
P =0.000;AUROC =0.943
P =0.010)
and the cutoff points were 19.5(J =0.798;J =0.82). Children with high VIS [VIS(24MAX)≥19.5] had significantly higher odds of mortality(25% & 0%
χ2=6.688
P=0.01)
poor outcomes(66.67% & 2.44%
χ2=22.799
P=0.000)
lactate(5.68 & 1.67
t=3.329
P=0.006)
prolonged time to first exudation(133.89 & 38.56
t=4.207
P=0.002)and PICU length of stay(7.67 & 3.27
t=4.247
P=0.002)compared with children with low VIS[VIS(24MAX)<19.5]. Conclusion:Maximum VIS calculated in the first 24 hours[VIS(24MAX)] after PICU admission is strongly and significantly associated with clinical outcomes in infants after cardiac surgery. The higher the VIS
