Semipermanent venous catheters remain the most commonly used access for chr
onic hemodialysis (HD) in pediatric patients. The recent availability of Te
sio catheters in 7 and 10 F has expanded available HD catheter options for
children and adolescents. We report our experience with Tesio catheter surv
ival, complications, and effect on dialysis adequacy in comparison to stand
ard dual-lumen (DL) catheters in our pediatric HD patients. Demographic dat
a were similar between the two groups. Overall actuarial survival was signi
ficantly longer for Tesio versus DL catheters (46% versus 0% at 1 year; P =
0.003). A comparison of smaller catheters (7 F Tesio catheter, 8 or 10 F D
L catheter) showed that smaller Tesio catheters had a significantly longer
survival (median survival, 244 versus 13 catheter-days; P < 0.01). Tesio 10
F catheters also survived significantly longer than the larger 11.5 and 12
F DL catheters (P < 0.02). Catheter sepsis occurred less frequently with T
esio catheters (one episode/20 catheter-months) than DL catheters (one epis
ode/5 catheter-months) despite the longer duration of Tesio catheters. Adeq
uate dialysis (single-pool Kt/V > 1.2) was delivered with the same frequenc
y, but for a longer duration with Tesio catheters (76% +/- 32% over 100 mon
thly measurements versus DL catheter, 57% +/- 45% over 54 monthly measureme
nts). Our clinical practice was to replace cuffed catheters when adequate d
ialysis could not be delivered. We conclude that Tesio catheters provide su
perior performance compared with DL catheters in terms of catheter survival
, Infection rates, and duration of adequate performance. (C) 2001 by the Na
