Objective To compare the effect of enteral administration and intravenous infusion of hypertonic electrolyte glucose solution (HEGS) in the resuscitation of burn shock. Methods Fifteen beagle dogs with 35% TBSA third degree burn were used in present study, and divided into three groups randomly: noresuscitation group, intravenous infusion resuscitation group and enteral administration resuscitation group. For the animals in the latter two groups, 1.8% HEGS was administrated intravenously or enterally for resuscitation 30 min after burn. The volume of fluid infusion in the first 8h was 1ml/(kg?1% TBSA), and the transfusion velocity was equilibrated. The mean arterial pressure (MAP), cardiac index (CI), plasma volume (PV), and sodium concentration in plasma were obtained to evaluate the effect of resuscitation used HEGS. Results The MAP, CI and PV were similar in both enteral and intravenous groups, which were higher than those in noresuscitation group. In both enteral and intravenous groups, MAP was raised after burn and then lowered after resuscitation, meanwhile CI and PV were raised and then lowered after resuscitation, but there were no differences between the two groups. The sodium concentration in plasma was stable in the noresuscitation group and increased in enteral and intravenous groups, and it was higher in intravenous groups than in enteral group. Conclusion In the resuscitation of early shock of 35% TBSA three degree burns, the effect of 1.8% HEGS administrated enterally on CI, PV, MAP and sodium concentration in plasma was similar to that of intravenous infused.

Objective To study the resuscitative effect of hypertonic electrolyte glucose solution (HEGS) on the haemodynamics pa-rameters in enteral resuscitation of burn shock. Methods Eighteen beagle dogs with 35% TBSA third degree burned were used in this stud-y. They were random divided into no-resuscitation group (NR group), enteral resuscitation with HEGS group (EH group) and intravenous resuscitation with isotonic electrolyte glucose solution (lEGS) group (Ⅱ group). The fluid resuscitation was given from half an hour after TBSA). The haemodynamics parameters (cardiac index, mean arterial pressure, intrathoracic blood volume index, and systemic vascular re-sistance index) were continuously assessed by PICCO. Result The cardiac output index reduced markedly after bum in the three groups, and then returned after 2h in two resuscitation groups, which were higher than that in the NR group( P<0.05). The mean arterial pressure reduced in the three groups, which was higher in the two resuscitation groups than that in NR group(P < 0.05). The intrathoracic blood volume index was rapidly reduced in the three groups. It returned in EH group from 2 hours after burned, which was still higher than that in the other two groups (P < 0.05). Meanwhile the systemic vascular resistance index was increased quickly. It was reduced in EH group from 2 hours after burned, which was lower than that in the other two groups (P < 0.05). Conclusion The results show that it was feasible for 35% TBSAⅢ° burn-injury dogs to be resuscitated with 1.8% hypertonic electrolyte-glucose solution by enteral, which can markedly reduce liquid quantity needed.
