犬50%Ⅲ度烧伤后早期脏器含水量的变化

Changes of organ water content in the early stage of 50% third degree burns in dogs

本实验观察了犬50％Ⅲ度烧伤后不输液以及按Parkland公式立即和延迟补液后,主要脏器血管外水量、残留血液水量和总水量的变化,以检测补液迟早对组织含水量的影响。结果表明:50％Ⅲ度烧伤的狗,不管输液与否或迟早,多数脏器含水量均高于正常,特别是血管外水量增加较多,而残留血液水量大多增加不显著。表明烧伤后脏器含水量的增加,主要系组织水肿,而脏器充血或瘀血不显著。

In order to verify the effects of postburn fluid infusion on the tissue water content,extravascular water volume,residual blood water volume,and total water volume of the major organs were measured in dogs inflicted with 50% TBSA third degree burns and the dogs received no fluid infusion,immediate infusion or delayed infusion respectively.It was found that the water contents of most of the canine organs,no matter they received fluid infusion or not,were higher than those of the control.The increase was especially marked in the extravascular water volume and less marked in the residual blood water volume,which suggests that the increase of water content of most of the organs of the burned animals results mainly from tissue edema rather than congestion and/or stasis of blood.
