RESUMO
Objective To investigate effect of continuous veno-venous hemofiltration on treatment of children with acute re-spiratory distress syndrome .Methods A total of 84 cases of children with acute respiratory distress syndrome were divided into control group (n= 42) and observation group (n = 42) .Control group was given conventional therapy including etiological treat-ment ,mechanical ventilation ,fluid management and anti-inflammatory treatment .Besides conventional therapy similar to control group ,observation group was administrated continuous veno-venous hemofiltration .Gender ,age ,admission critical illness score (PICS) ,clinical manifestations ,blood gas indexes (PaO2 ,SaO2 ) and oxygenation index (OI = PaO2 /FiO2 ) before and after treat-ment ,duration of mechanical ventilation ,pediatric intensive care unit (ICU) hospitalization days and mortality in above two groups were analyzed retrospectively .Results There were not significant difference in gender ,age and admission critical illness score (PICS) of two groups(P> 0 .05) .PaO2 ,SaO2 and OI of observation group were higher than that of control group in the third and fifth day after treatment (P < 0 .05) .The average ICU hospitalization day of observation group was shorter than that of control group (P< 0 .05) .Mortality of observation group was lowered compared with control group (P< 0 .05) .Conclusion Veno-venous hemofiltration could effectively reduce duration of mechanical ventilation and mortality in treatment of children with acute respirato -ry distress syndrome ,which is worth clinical popularization .
