Blood pressure drop during dialysis — the most common intradialytic complication, driven by ultrafiltration.
Intradialytic hypotension (BP fall with symptoms) results from ultrafiltration exceeding plasma refill, autonomic dysfunction, and cardiac disease. Prevention: correct dry weight, sodium modeling, cooler dialysate, midodrine in refractory cases, and avoiding large meals during sessions. It predicts mortality and access thrombosis.
The process of removing excess fluid from a patient's blood during dialysis by applying pressure across the dialyzer membrane.
The target body weight of a dialysis patient after all excess fluid has been removed — the weight at which blood pressure is normal without medication.
The sodium concentration of the dialysis bath — a lever for blood pressure, thirst, and intradialytic symptoms.
Excess extracellular fluid volume in kidney patients from inadequate excretion, causing edema, hypertension, pulmonary congestion, and increased cardiovascular risk.
