Abstract:
Objective:To explore the predictive value of relevant hemodynemics indexes on cardiac shock prognosis by PiCCO technology.
Methods:A total of 54 consecutive patients with cardiac shock treated in our hospital from 2012-01 to 2013-05 were studied. The patients’ general information with hempdynemics indexes as cardiac index (CI), extra vascular lung water index (EVWI), general ejection fraction (GEF), general end diastolic index (GEDI), systolic vascular resistance index (SVRI) were monitored by PiCCO technology at before and 48 hours after treatment. Based on 28 days surviving condition, the patients were divided into 2 groups:Survival group, n=28 and Death group, n=26. The levels of above indexes were compared between 2 groups and their predictive values on cardiac shock prognosis were calculated by ROC curve analysis.
Results:Compared with Death group, Survival group presented much higher CI, GEF and much lower EVWI, SVRI at before and 48 hours after treatment, P<0.05-0.01, while GEDI was similar between 2 groups, P>0.05. With 48 hours treatment, the ROC analysis showed AUCEVWI=0.846 with cut-off point at 7.5ml/kg, AUCCI=0.884 with cut-off point at 3.46 L/(min·m2) and AUCGEF=0.853 with cut-off point at 16.5%;the sensitivity and speciifcity of EVWI, CI, GEF were 79.2%and 81.0%, 82.8%and 83.0%, 74.1%and 88.7%respectively. Multivariate Logistic regression analysis indicated that CI and EVWI were the independent predictors for cardiac shock prognosis.
Conclusion:PiCCO monitoring technology may guide the balance of relevant hempdynemics indexes in patients with cardiac shock. With 48 hours treatment, the levels of CI and EVWI had predictive value for cardiac shock prognosis.
