Methods: HSD was used for resuscitation 6 h postburn in dogs and its effect on cardiac function was evaluated byvolume load,MAP, LVSP,LVEDP, + dp/dtmax, -dp/dtmax, CO and SVR. Results: The volume of HSD was 30.50% less duringfirst 24 h postburn and 59.50% less during 4 h after resuscitation than that of lactated Ringer’s solution (LR’s). MAP, LVSP,LVEDP, + dp/dtmax, -dp/dtmax and CO increased and SVR reduced in HSD resuscitation. Conclnsion: Smaller volume of HSD canexpand plasma volume significantly and improve cardiac function in delayed resuscitation of burn shock.展开更多
