Influences of Traumatic Brain Injury on the Outcomes of Delayed and RepeatedHemorrhages

摘要

Effects of traumatic brain injury (fluid percussion) on outcomes of hemorrhage,either delayed (70.5 min after the injury) or repeated (0.5 min after injury, then followed by a delayed hemorrhage), were examined in 4 groups of 1 0 anesthetized rats. Comparisons were made for delayed hemorrhage following sham injury (Al) vs. injury (A2) and for repeated hemorrhage following sham injury (Bl) vs. injury (B2). No significant differences were observed in MAP, Cl, HR, SVI, SVRI, and CVP between groups Al and A2. Hemodynamic recovery was significantly better in Bl than B2 at 70 min after the initial hemorrhage. The
