Objective:To study the clinical value of blood lactic acid level of patients in HFMD in chidren.Methods According to APACHE II system,651 patients were divided into three grou ps:non-critical group,critical group and exetremely critical group. Analysis of each group 1h, 12h, 24h and 48h of the dynamic changes of blood lactate .Blood lactic acid level were compared among these groups and among different prognostic.Results Exetremely critical group’s blood lactate levels higher than the other two groups and showed increasing trend continued; while the other two groups a lower blood lactate levels, and decreased gradually with the progress of the treatment.The higher APACHE II was, the higher level of blood lactic acid was(r=0.67,P<0.01).The prognosis of the patiens had a correlation with the level of blood lactic acid.Conclusion The blood lactic acid level is a useful index for the prognosis evaluation in HFMD complications of encephalitis patients. The higher the blood lactic acid level the patients have , the worse prognosis they have ,especially when the blood lactic acid value has been in high level for a long time. |
