Research on visual deep vein puncture and catheterization

Objective To investigate the effect and adverse reaction of the self-made visual deep vein puncture needle.Methods Sixty adult dogs were randomly divided into jugular vein puncture group(30 dogs) and femoral vein puncture group(30 dogs).Vein display,success catheterization,and edema after pressure injection of saline were observed and compared between two groups.Results The vein puncture was clearly showed and the catheterization was successful in both groups.The definition in femoral vein group was slightly higher than that in jugular vein.Edema occurred in puncture site after local pressure injection in both groups;but the edema was more obvious in femoral vein group compared with that in jugular vein group(P0.05).Conclusion Visual puncture technique can effectively improve the precision and security of puncture,facilitate the operation of difficult puncture,and reduce the incidence of puncture complications.
