The relationship of sealing catheter with different concentration of heparin sodium and obstruction after percutaneous insertion of subclavian venous catheters

Abstract

Objective To investigate the relationship of sealing catheter with different concentration of heparin sodium and obstruction after percutaneous insertion of subclavian venous catheters.Methods A total of 889 cases of tumor with percutaneous insertion of subclavian venous catheters were individed into two groups, group A was flushed with (50 U/ml) 5 ml heparin sodium before and after infusion,and group B were flushed with (50 U/ml) 5 ml heparin sodium before and after infusion.Results 5.55% (25/889) of catheter obstruction in group A were occurred and 1.13% (5/889) of catheter obstruction in group B were occurred, there wss signification difference between the two groups (P ＜0.05) .Conclusions There is an obvious relationship of sealing catheter with different concentration of heparin sodium and obstruction after percutaneous insertion of subclavian venous catheters.Flushing catheter with 125 U/ml heparin sodium can reduce thecatheter obstruction rate effectively.
