Effects of early postburn escharectomy on the permeability of cadiac and pulmonary blood vessels in rats / 第三军医大学学报

ABSTRACT

Objective　To evaluate the prophylactic-therapeutic role of escharectomy during early postburn stage on internal organ dysfunction. Methods　A total of 72 Wistar rats were randomized into 3 groups burn without escharectomy group (A group), burn with escharectomy during early postburn stage (B group) and normal control. Vascular permeability were measured with 99Tc-labelled albumin. Furthermore, the effect of burn sera on permeability of monolayer of vascular endothelial cell (EC) was observed. Results　Vascular permeability in group B was significantly lower than in group A. When exposed to burn sera, EC monolayer permeability in group B is decreased when compared with group A. Conclusion　Escharectomy during early postburn stage could restore endothelial permeability
