ABSTRACT
Abstract Purpose To develop a rabbit model of a short peripheral catheter (SPC) and to observe the effects of different flushing methods on blood vessels. Methods Thirty rabbits were randomly divided into three groups (A, B, and C), with ten rabbits per group. In group A, we used pulsed flush; in group B, we used uniform flush; and no treatment was used in group C. Results We observed that a uniform flush reduced blockage, phlebitis, and exudation compared to a pulsed flush by visual observation. The histopathological examination found that the morphological changes in group A were more severe than in group B and C related to loss of venous endothelial cells, inflammatory cell infiltration, edema, epidermal and chondrocyte degeneration, except for the thrombosis on group B that was more serious than in group A, especially in the distal side of puncture points. The distal region of groups A and B had more inflammatory cell infiltration than the proximal region. Thrombosis was more severe in the distal region than in the proximal region in group B. Conclusions The uniform flush produced less damage to the vascular endothelium and surrounding tissues and was superior to the pulsed flush. However, the uniform flush is prone to thrombosis.
