Abstract：OBJECTIVE: To study risk factors for severe hand, foot and mouth disease (HFMD) complicated by heart and lung failure and treatment experience. METHODS: A total of 198 children with severe HFMD between March and August in 2011 were enrolled. Univariate analysis and logistic regression model were used to analyze the risk factors severe HFMD complicated by heart and lung failure. The effects of combination therapy with immunoglobulin+dexamethasone+ribavirin were observed. RESULTS: Univariate analysis indicated that HFMD patients with heart and lung failure had higher proportions of consciousness, tachypnoea, abnormal hemodynamics, increased troponin and EV71 infection than HFMD patients without heart and lung failure (P<0.05).Multivariate logistic regression analysis indicated that tachypnoea, abnormal hemodynamics and EV71 infection were the main risk factors for heart and lung failure. Compared with combination therapy with dexamethasone+ribavirin, combination therapy with immunoglobulin+dexamethasone+ribavirin was more effective for preventing hemodynamic changes in children with severe HFMD (P<0.01). Compared with HFMD patients with heart and lung failure, the effect of the combination therapy with immunoglobulin+dexamethasone+ribavirin was better in HFMD patients without heart and lung failure (P<0.01). CONCLUSIONS: The main risk factors for heart and lung failure in children with severe HFMD include tachypnoea, abnormal hemodynamics and EV71 infection. Early combination therapy with immunoglobulin+dexamethasone+ribavirin can reduce the incidence of heart and lung failure in children with severe HFMD.
