The role of plasma volume and fluid overload in the tolerance to ultrafiltration and hypotension in hemodialysis patients.

Introduction: Ultrafiltration (UF) in hemodialysis (HD) patients is accompanied by irregular falls in plasma volume (PV) and blood pressure (BP).

Methods: We obtained in 321 patients (large cohort), body weight (BW), BP, samples of blood to determine hemoglobin (Hb) and hematocrit (Ht), Pre and Post HD. We estimated the % variation of the PV and its effect on the BP.

Survival and Clinical Outcomes of Tunneled Central Jugular and Femoral Catheters in Prevalent Hemodialysis Patients.

Background: The literature on the outcomes of tunneled femoral catheters compared to that of jugular catheters is scarce and derived mainly from small cohorts.

Material And Methods: Seven hundred and sixty six catheters were placed in 673 hemodialysis patients, 622 in the jugular/subclavian veins and 144 in the femoral veins. Patients were followed prospectively for 36 months.
