Abstract
Objective. To reveal the correlation between the cerebral oxygenation level and the values of cerebral perfusion at patients with head injury (HI). Material and methods. The perfusion computer tomography (CT) of brain and simultaneous registration of SctO2 level using cerebral near-infrared oxymeter were performed at 20 patients suffered from HI. The average age was 34,5±15,6 years old (from 15 till 65 years old). There were 9 men and 11 women. Results. The severity of patients’ state according to ISS (Injury Severity Score) scale was 54,7±14,6 scores (from 25 till 81 scores). The level of consciousness according to GCS (Glasgow Coma Score) was 10,4±2,5 scores (from 5 till 13 scores) at the beginning of trial. The mean value of SctO2 was 63±8,2% (from 53 till 87%). The mean value of CBV was 2,1±0,67 ml/100 g (min - 1,1; max - 4,3 ml/100 g). The mean value of CBF was 31,99±13,6 ml/100 g х min (from 11,6 till 80,8 ml/100 g х min). The mean value of MTT was 5,7±4,5 sec (min - 2,8; max - 34,3 sec). The mean value of TTP was 22,2±3,1 sec. Conclusion. The level of cerebral oxygenation at patients with HI is definitely correlated to the values of cerebral blood volume (CBV) (p<0,000001). There was no significant correlation between the oxygenation level of brain tissue and other measures of cerebral perfusion.
