[Effects of hypertonic sodium lactate dextran resuscitation in severely burned dogs].
12 dogs with 35% TBSA third degree burns received HLD resuscitation (HLD group, n = 6) or LR resuscitation (LR group, n = 6). Fluid resuscitation started one hour postburn. The amount of fluid infused with HLD resuscitation was calculated by that after giving HLD 19.6 ml/kg in 3 hours and 6 ml/kg/% TBSA lactate Ringer's solution followed. The amount of fluid infused with LR resuscitation was calculated by 8 ml/kg/% TBSA lactate Ringer's solution. Infusion of lactated Ringer's solution in both groups was adjusted by maintaining urinary output 0.5-1 ml/kg/h. The volume of fluid infused in HLD group (5.05 +/- 1.11 ml/kg/% TBSA) was much less than that of LR group (10.03 +/- 1.30 ml/kg/%TBSA) (P < 0.01). There was no significant difference in urinary output, serum Na+ and albumin, and plasmacrystalloid osmolarity between two groups. Plasma level of MDA decreased after resuscitation with HLD, which (0.81 +/- 0.20 mmol/g Hb) was much lower than that (1.39 +/- 0.44 mmol/g Hb) of LR group 4 hours postburn (P < 0.05). Plasma SOD activity (7.22 +/- 0.68 u/g Hb) of HLD group were much higher than that of LR group (4.86 +/- 0.53 u/g Hb) 4 hours postburn (P < 0.05). HLD resuscitation could significant reduce the amount of fluid infused comparing with lactate Ringer's solution. HLD resuscitation could attenuate postburn damage to tissue induced by lipid peroxide by elevating plasma SOD activity.
