Abstract:
Objective To investigate the effect of rapid fluid replacement on hemorheology in delayed resuscitation after burn. Methods A total of 32 dogs inflicted with 40%TBSA full thickness scalding were randomly divided into 4 groups: scald control group(C group), delayed Gelofusion even replacement group (GE group), rapid fluid replacement group (GR group), and delayed plasma rapid fluid replacement group (PR group). The femoral arterial pressure, viscosity of blood and plasma, packed cell volume and aggregation of RBC were detected at the intervals of before and 2, 6, 8, 12, 24, 36 and 48 hours after scalding. Results The viscosity of blood markedly increased at 2 hours after scalding, and the hemorheology parameters decreased after fluid resuscitation. The hemorheologic parameters were obviously lower in GR group than in GE group at 2 hours after rapid resuscitation, the viscosity of blood and RBC aggregation in GR group were obviously lower than those in PR group. Conclusion Under the condition of delayed resuscitation after burn, rapid fluid replacement can quickly decreased the state of blood high viscosity and may play a role in improving microcirculation and treating burn shock.
