説明

It is well known that femoral vein catheterization is the safest method of establishing temporary blood access. Although walking is permitted when using blood access urokinase immobilized catheter (coaxial type) (UK-C) for blood access, there is no report on the safety of walking using a double axial type catheter. The present study compared the flexiblity of double axial type catheters. Then a clinical study of body movement during femoral vein catheterization was performed using the most flexible double axial type catheter.<br>In the basic examination, the rigidity of UK-C, blood access urokinase catheter (double axial type) (UK-D), Vas-cath Flexxicon dual lumen catheter and Quinton dual lumen catheter were measured at room temperature and at 37°C. The rigidity of UK-D was the lowest at 37°C, though that of UK-C was the lowest at room temperature.<br>In the clinical study, UK-D was used for blood access because it was the most flexible in the basic examination. Twenty patients were cannulated with UK-D via the internal jugular vein (IJV group) and the other 20 patients were cannulated with UK-D via the femoral vein (FV group). Both groups were observed during 6 hemodialysis sessions. Body movement was restrained only in the FV group. The levels of body temperature, white blood cells, C-reactive protein, blood flow rate did not significantly differ between the two groups. The degrees of redness at the catheter insertion site and the suture did not significantly differ between the two groups.<br>We concluded that the clinical incidence of infection and thrombus formation by short-term femoral vein catheterization using UK-D with restriction in body movement is similar to that observed in internal jugular vein catheterization. It is therefore suggested that short-term body movement such as walking and sitting may be permitted while using UK-D.
