Automatic Adaptive System Dialysis (AASD)
Automatic Adaptive System Dialysis (AASD)
AASD is a new dialysis technique based on the use of a mathematical model of intradialytic
 solutes and fluid kinetic, for the automatic elaboration of dialysate sodium and
 ultrafiltration rate profile. The aim of dialysate sodium and ultrafiltration rate profile is
 to obtain the higher stabilization of intradialytic extra cellular compartment, in
 consideration of end session targets: body weight and final patient's natremia. In this
 multicenter prospective controlled randomized trial the primary end-point is the clinical
 efficiency validation of AASD on intradialytic hypotension but also on thirst, cramps,
 headache, nausea, vomiting, hypotensive events observed in basal treatment (HD or HDF).
Inclusion Criteria:Patients in HD/HDF (bicarbonate dialysis/hemodiafiltration) for at least
 6 months

 -  aged more than 18 years

 -  on chronic thrice-weekly HD

 -  symptomatic hypotension during at least 30% of dialysis sessions on basal treatment in
 the last month before admission or/and 1 hypotension /week

 -  disequilibrium symptoms (cramps, headache, nausea, vomiting, hypotensive events) in at
 least 30% of dialysis sessions on basal treatment

 -  dialysis session time: 4 hours (as much as possible)

 -  Signed inform consent form

 -  Patients having no vascular access related problems (bi-ponction, blood flow rate
 300ml/min)

 Exclusion Criteria: Patients in a pregnant state

 -  Patients whose life expectancy is less than study period

 -  Patients with progressive acute pathology (neoplasia…)

 -  Patients included in an other protocol

 -  Psychiatric patients or patients unable to consent or unable to follow the study
