Objective: To analyze the prognostic factors of liver failure in children.
Methods: The clinical data of 105 children with liver failure treated in the No. 302 Hospital in the past 17 years were retrospectively analyzed. The related factors were analysed by EXCELL 2000 and STATA 7.0, multivariate statistical analysis was performed by Logistic regression.
Results: (1) A total of 72 children died and the mortality was 68.6%. (2) Univariate statistical analysis showed that the factors significantly correlated with death were age, clinical type and stage of liver failure, decrease in prothrombin activity (PTA) and albumin (AIB) level, increase in serum level of total bilirubin (TBIL), appearance of deviation of TBIL and ALT, complications and hepatic encephalopathy. There was no significant difference between boys and girls. (3) There was no significant difference among etiological diagnoses such as HBV infection, Wilson's disease, and unknown pathogeny. (4) Multivariate statistical analysis showed that PTA (P = 0.000) and TBIL (P = 0.029) were independent risk factors of mortality of the children.
Conclusion: The prognosis of liver failure in children is poor and mortality is high. PTA and TBIL might be useful for indicating prompt diagnosis and treatment to improve survival rate of the children with liver failure.
