Detection of myocardial enzymes, cardiac troponin T and hepatic and renal function in the diagnosis and treatment of severe pneumonia in children

OBJECTIVE: To analyze the significance of myocardial enzymes, cardiac troponin T (cTnT) and hepatic and renal function in the treatment of severe pneumonia in children. METHODS: One hundred and twenty children with severe pneumonia who were admitted to the hospital between April 2015 and February 2017 were selected and included as a severe pneumonia group; 120 children with common pneumonia were included as a common pneumonia group; 100 healthy children were included as controls. The myocardial enzymes, cTnT and hepatic and renal function of patients in the three groups were detected and compared. The children with severe pneumonia were divided into a mild hypoxia group, a moderate hypoxia group and a severe hypoxia group according to arterial partial pressure of oxygen; the myocardial enzymes, hepatic and renal function and cTnT of the children in the three groups were compared. The correlations of partial pressure of blood oxygen with myocardial enzymes, hepatic and renal function and cTnT were analyzed. RESULTS: The levels of myocardial enzymes, hepatic and renal function and cTnT of the severe pneumonia group, common pneumonia group and control group declined, and the differences had statistical significance (P<0.05). The levels of myocardial enzymes, hepatic and renal function and cTnT were higher in the children with severe hypoxia. The partial pressure of blood oxygen was in a negative correlation with myocardial enzymes, hepatic and renal function and cTnT in the severe pneumonia group. CONCLUSION: Timely monitoring of myocardial enzymes, hepatic and renal function and cTnT has an extremely important role in the evaluation of children with severe pneumonia.
