Wu Qingyun,Ren Qiu zhi ,Chen CunFu,et al.The91th Hospital of PLA,Yan zhou272100,China  
Objective To probe the influence of hemodynamics on delayed fluid resuscitation burned rats with escharotomy operation combined with rapid infusion.Methods The30%TBSAⅢdegree burned rats were began to rapid infusion at6h postburn,for2h,they were subjected to escharotomy and homograft.Then the hemodynamic indexes,in cluding LVSP,LVEDP,AOSP,AODP,MAP,±dp/dtmax were measured and the fatality rate at48h postburn were observed.Results At 1h postburn,the hemo-dynamic in dexes were decreased.At 6h postburn,they were decreased to the lowest level.After infusion,they were obviously increased;at12h postburn,the influences of escharotomy on hemodynamic indexes weren' t obvious.At 24h postburn,the hemodynamic indexes were obviously im proved in escharotomy group.At 48h postburn,two groups weren't obviously different and the fatality rate of escharotomy group was higher than that of unescharotomy group.Con clu sion Es charotomy can improve hemodynamic in-dexes for delayed fluid resuscitation burned rats.But ,its fesibility in clinic must be probed further.
