Abstract：Objective To analyze changes in lactic acid level in patients with late-onset intracranial hematoma after craniocerebral injury and investigate their relativity.Methods Forty-eight patients with late-onset intracranial hematoma after craniocerebral injury treated in our hospital between May 2009 and December 2012 were enrolled as observation group.There were 32 males and 16 females.Moreover,50 cases checked up in our hospital during the same period were studied as health population controls,including 35 males and 15 females.Level of lactic acid was measured on admission,at the time of definite diagnosis as well as at days 7 and 14 after treatment and compared between groups.Results Level of lactic acid was (1.77 ±0.21) mmol/L in control group and (1.82 ± 0.25) mmol/L in observation group respectively on admission (t =1.070,P ＞0.05) ; Level of lactic acid was (3.32 ± 0.89) mmol/L in observation group at the time of definite diagnosis,which increased to (3.74 ± 1.16) mmol/L at days 7 after treatment and decreased to (1.89 ±0.75) mmol/L at days 14 after treatment.When diagnosed and treated for 7 days,level of lactic acid differed significantly between the two groups (P ＜0.05).Level of lactic acid related to craniocerebral injury at each time point,but higher correlation coefficient was observed at the time of definite diagnosis and 7 days after treatment with 0.986 and 0.989 respectively.Conclusion Level of lactic acid relates to late-onset intracranial hematoma after craniocerebral injury,which can be used as reference for progression of the disease.
