[Determination of the age of subdural hematomas from the concentration of hemoglobin].
The photocolorimetric method was employed to measure hemoglobin levels in 46 traumatic subdural hematomas of different age. The data thus obtained were used to construct a logarithmic regression model for the determination of the age of subdural hematomas from the concentration of hemoglobin. The model allows to determine injury time points and intervals at any desired level of confidence probability. The fraction of dispersion of hematoma age values attributable to regression was estimated at 41% which accounts for 74.7% of the maximally possible magnitude. Results of the study can be used in practical work of a forensic-medical experts.
