Key result
Precise dry weight, biofeedback systems, and cool dialysate mitigate intradialytic hypotension.
Why the study?
Intradialytic hypotension significantly contributes to morbidity and mortality in maintenance hemodialysis patients, and strategies to prevent it are evolving.
Bioimpedance technology and biofeedback systems can help prevent intradialytic hypotension in patients undergoing maintenance hemodialysis.
May support biofeedback and cool dialysate to lessen intradialytic hypotension; leaves open confirmation in randomized trials.
Intradialytic hypotension has a significant role in the morbidity and, in some cases, the mortality associated with maintenance hemodialysis. Greater precision in the determination of dry weight using bioimpedance technology and biofeedback systems designed to prevent rapid fluctuations in blood volume has recently been shown to decrease the frequency of this complication. Pharmacologic strategies designed to maintain peripheral vascular resistance in patients with insufficient release of endogenous vasoconstrictors continue to be explored. The sudden development of intradialytic hypotension may respond to specific antagonists to hypotensive mediators.

Atanasova et al. (2020) conducted a review in Intradialytic hypotension. Intradialytic hypotension is a frequent complication of hemodialysis associated with significant morbidity and mortality, which can be mitigated by precise dry weight determination, biofeedback systems, and cool dialysate.
