Objective: Forensic medical assessment of the age of intracranial hematomas according to the concentration of methemoglobin Material and Methods. We studied 77 cases of traumatic brain injury with intracranial hemorrhages. Among them, 52 were males and 25 females. The age category of the deceased ranged from 20 to 65 years. The study used the spectrophotometric method, by which the concentration of methyl hemoglobin in the intracranial hematomas was determined. Results We performed spectrophotometric analysis of methyl hemoglobin concentration in blood from intracranial hematomas of those who died of craniocerebral injuries. Blood from the superior sagittal sinus of the dura mater was used as a control. The spectrophotometric results obtained from the difference in MetHb concentrations from the intracranial hemorrhages and the control blood group at different times of traumatic brain injury were evaluated. The results obtained were compared MetHb concentrations between the observation groups according to the life expectancy of the victims after injury. All cases were divided into 7 groups according to periods of posttraumatic hematoma development: 1) up to 3 hours; 2) up to 12 hours; 3) up to 24 hours; 4) up to 48 hours; 5) up to 60 hours; 6) up to 72 hours; and 7) over 3 days. Conclusions: Thus, in practice we have proved that the concentration of methemoglobin changes in the blood in various pathological states, as well as there is a direct correlation between the content of MetHb in the blood coagulation in case of CHT and the time of the organism after trauma. Determination of the age of intracranial hematomas by spectrophotometric method is of great importance for the resolution of many problems in the field of medicine.
