Clinical evaluation on inserting haemodialysis cuffed catheter using guidewire through temporary catheter

Objective To evaluate the appheation of inserting haemodialysis cuffed catheter using guidewire through temporary catheter in maintenance haemedialysis. Methods Compared with 24 cuffed catheter inserted by puncturation of right internal jugular vein (B group), application of 22 cuffed catheter inserted by guidewire through temporary catheter in right internal jugular vein (A group) were observed. Results Median survival time was 19 months in A group and 21 months in B group. There was no significant difference in survival curve between A group and B group ( χ2= 0.05, P = 0.82). Compared with those in B group, the incidence of local infection[ (0.13 ± 0.01 ) per 100 catheter days vs (0.15 ± 0.02 ) per 100 catheter days], systemic infection [(0.31 ± 0.03) per 100 catheter days vs (0.32 ± 0.02) per 100 catheter days], errhysis or haematonm in catheter [ 40.91% (9/22) vs 45.83% (11/24)], the blood flow in haemodialysis using catheter [(230.53±28.27) ml/min vs (238.71±25.94) ml/min] and the thrombus in catheter [31.82%(7/22) vs 33.33%(8/24) ]were no significant difference. And there were no occurrence of fibrous sheath and right internal jugular vein stenosis in both groups. Conclusion Inserting haemodialysis cuffed catheter in right internal jugular vein by using guidewire through temporary catheter is an alternative strategy, because of avoiding this avoids vein re-puncturation and doesn't increase catheter related complication.
