%X UNASSIGNED: Hyperperfusion therapy, mean arterial blood pressure (MAP) > 85 mmHg, is a recommended treatment of blunt traumatic spinal cord injury (SCI). We hypothesized the first 24 h of MAP augmentation would be most influential on neurological outcomes.
UNASSIGNED: This retrospective study from a level 1 urban trauma center dating 1/2017 to 12/2019 included all blunt traumatic spinal cord injured patients receiving hyperperfusion therapy. Patients were grouped as "No improvement" vs "Improvement" measured by change in American Spinal Injury Association (ASIA) score during their hospitalization. MAP values for the first 12, first 24 and last 72 h were compared between the two groups; P < 0.05 was significant.
UNASSIGNED: After exclusions, 96 patients underwent hyperperfusion therapy for blunt traumatic SCI, 82 in the No Improvement and 14 in the Improvement group. Groups had similar treatment durations (95.6 and 96.7 h, P = 0.66) and ISS (20.5 and 23, P = 0.45). The area under the curve, calculation, to account for time less than goal and MAP difference from goal, in the No Improvement group was significantly higher (lower and more time below MAP goal) compared to the Improvement group for the first 12 h (40.3 v. 26.1 P = 0.03) with similar findings in the subsequent 12 h of treatment (13-24 h; 62.2 vs 43, P = 0.09). There was no difference between the groups in the subsequent 72 h (25-96 h; 156.4 vs 136.6, P = 0.57).
UNASSIGNED: Hyperperfusion to the spinal cord in the first 12 h correlated significantly with improved neurological outcome in SCI patients.
