Influence of ratio of diameter of catheter vein / catheter on PICC related venous thrombosis
Abstract：Objective:To probe into the influence of peripherally inserted central venous catheter(PICC) on the ratio of diameter of catheter to the vein(PICC),and to provide the basis for the selection of appropriate catheter.Methods:A total of 170 patients who met the criteria were selected as the subjects from September 2015 to March 2016 before and after catheter using SiteRite5 ultrasound for vascular assessment,measuring catheter vein diameter,venous catheter catheterization calculation / diameter ratio,and assessed the occurrence of thrombosis.Up to 28 days,they were suspected to have thrombosis by ultrasound confirmed that there was no thrombus formation,on the different venous thrombosis/catheter diameter ratio were compared.Results:Ultrasound confirmed 59 cases(34.7%) of catheter thrombosis,venous catheter/diameter ratio less than 2,2 to 3,and the incidence of thrombosis in 3 patients were 2.6%,40.7%,21.5%,the difference was statistically significant(χ2=9.030,P=0.011).Conclusions:Catheter vein catheter/diameter ratio was smaller,the higher the incidence of thrombosis it recommended the use of visualization tools to evaluate venous venous catheter size,according to the size of the initiative to select the appropriate type of catheter,venous catheter catheterization increased/diameter ratio,prevention of thrombosis prospective.
