[Correlation between the Liège scale and a biomechanical marker of the cerebral lesion]

Brain type creatine kinase isoenzyme (CK.-1) was measured in the ventricular cerebrospinal fluid in a series of 42 patients within 7 +/- 3,4 hours following severe head injury (GCS less than or equal to 7, LCS less than or equal to 12). The presence of the CK.-1 isoenzyme correlated with the degree of head injury as indexed by the Glasgow coma scale and the Liege coma scale. There was a significant logarithmic correlation between CK.-1 activity in the C.S.F. and the coma scores. However, the correlation with the Liege coma scale score (r = -0,84) is significantly better (Z = 1,97; p less than 0,05) than with the Glasgow coma scale score (r = -0,65). Thus, the Liege coma scale is a better index of neurological trauma.
