Background: Sodium prescription in patients with intradialytic hypotension remains a challenge for the attending nephrologist, as it increases dialysate conductivity in hypotension-prone patients, thereby adding to dietary sodium levels.
Methods: New sodium prescription strategies are now available, including the use of a mathematical model to compute the sodium mass to be removed during dialysis as a physiological controller.
Results: This review describes the sodium load of patients with end-stage renal disease on chronic hemodialysis (HD) and discusses 2 strategies to remove excess sodium in patients prone to intradialytic hypotension, namely, Profiled HD and the hemodiafiltration Aequilibrium System.
Conclusion: The Profiled HD and Aequilibrium System trial both proved effective in counteracting intradialytic hypotension.

Intradialytic hypotension (IDH) is a common occurrence in hemodialysis. IDH occurs when there is a drop in blood pressure along with hypotensive symptoms. There are various causes of IDH, and it is important to consider proper management of this condition.

Introduction: The low incidence of intradialytic hypotension (IDH) in high-volume (HV) hemodiafiltration (HDF) may help in maintaining gut perfusion during treatment. Preservation of gut endothelial integrity would limit or prevent bacterial translocation and subsequent systemic inflammation, which may contribute to the low mortality rate in HV-HDF.
Methods: Forty patients were cross-over randomized to standard (hemodialysis [HD]) (S-HD), cool HD (C-HD), and HDF (low-volume [LV] and HV, convection volume (CV) of 15 L and ≥ 23 L per session, respectively), each for 2 weeks.

: High-volume online hemodiafiltration (OL-HDF) has proven to be the most efficient dialysis modality and to offer better clinical outcomes in patients on hemodialysis. Longer and more frequent dialysis sessions have demonstrated clinical and survival benefits. : A single-center observational study of the first one hundred patients on nocturnal every-other-day OL-HDF was conducted with the aim of reporting the experience with this treatment schedule and evaluating analytical and clinical outcomes as well as the patient and technique survival.

Objective: To evaluate the effectiveness and safety of artificial intermittent infusion hemodiafiltration (I-HDF) in maintenance hemodialysis (MHD) patients with intradialytic hypotension (IDH), and to determine the optimal infusion dosage.
Methods: This single-center, prospective, self-controlled study included 30 MHD patients with IDH, treated from December 2022 to July 2023. Patients underwent three sessions of I-HDF as treatment group and conventional hemodialysis as control group.

Background: Intradialytic hypotension (IDH) is a common and serious complication in renal replacement therapy, especially in hospitalized patients. The absence of a standardized definition complicates data synthesis and the development of evidence-based guidelines. Current definitions vary, including different blood pressure thresholds, clinical symptoms, and the need for medical intervention during dialysis.
