Venous pressure monitoring does not accurately predict XXXX in @entity1 .

@entity177 @entity1 @entity2548 @entity715
@entity177 is a significant cause of morbidity and mortality in hemodialysis @entity1 . Routine monitoring of arteriovenous (AV) fistulas and grafts could increase access longevity. Dynamic venous pressure monitoring is a surveillance test advocated to detect early signs of vascular @entity715 . Venous pressure measurements obtained, per DOQI recommendations, in @entity1 undergoing hemodialysis with an @entity2548 or graft were reviewed. Baseline venous pressures were established by calculating the mean of venous pressures obtained without an antecedent @entity715 . A paired t-test was performed comparing mean baseline pressure measurements with pressures immediately preceding each @entity715 episode. Since some @entity1 had multiple @entity715 episodes, the assumption of independence was not met. A second paired t-test was performed comparing mean baseline pressures with the mean pressure measurement per individual, obtained immediately preceding a @entity715 episode; 335 venous pressures were collected in ten pediatric @entity1 . Eighteen @entity715 occurred in five @entity1 , in whom a total of 241 venous pressures were measured. Venous pressures did not correlate with @entity715 events ( P=0.4284). Specific @entity715 events for each @entity1 were correlated with mean @entity1 -specific venous pressures and showed no correlation ( P=0.3229). Dynamic venous pressure monitoring is not an adequate predictor of access @entity715 in pediatric @entity1 .
