Key result
The Hemocontrol biofeedback system significantly reduced the frequency of symptomatic intradialytic hypotension sessions from 62.1% to 38.4% (P < 0.001) compared to conventional hemodialysis.
Why the study?
Does the Hemocontrol biofeedback system reduce intradialytic hypotension in hypotension-prone hemodialysis patients?
Does the Hemocontrol biofeedback system reduce intradialytic hypotension in hypotension-prone hemodialysis patients?
The Hemocontrol biofeedback system significantly reduces the frequency of intradialytic hypotension and promotes faster recovery from fatigue in hypotension-prone hemodialysis patients.

May reduce symptomatic intradialytic hypotension; leaves open need for randomized trials before practice change.
We conducted a study to determine whether the hemocontrol biofeedback system (HBS) can improve intradialytic hypotension (IDH) in hypotension-prone hemodialysis (HD) patients compared with conventional HD. In this multicenter prospective crossover study, 60 hypotension-prone patients were serially treated by conventional HD for 8 weeks (period A), by HD with hemoscan blood volume monitoring for 2 weeks (period B0), and by HBS HD for 8 weeks (period B1). The number of sessions complicated by symptomatic IDH during 24 HD sessions (14.9 ± 5.8 sessions, 62.1% in period A vs 9.2 ± 7.2 sessions, 38.4% in period B1, P<0.001) and the number of IDH-related nursing interventions in a session (0.96 ± 0.66 in period A vs 0.56 ± 0.54 in period B1, P<0.001) significantly decreased in period B1 than in period A. Recovery time from fatigue after dialysis was significantly shorter in period B1 than in period A. The patients with higher post-dialysis blood pressure, lower difference between pre- and post-dialysis blood pressure, less frequent IDH, and higher pre- and post-dialysis body weight in period A responded better to HBS in period B1 in regard to the reduction of IDH. In conclusion, HBS may improve the patient tolerability to HD by reducing the IDH frequency and promoting faster recovery from fatigue after dialysis.

Gil et al. (2014) studied Intradialytic hypotension-prone hemodialysis (n=60). Hemocontrol biofeedback system (HBS) vs. Conventional hemodialysis was evaluated on Number of sessions complicated by symptomatic intradialytic hypotension during 24 hemodialysis sessions (p=<0.001). The Hemocontrol biofeedback system significantly reduced the frequency of symptomatic intradialytic hypotension sessions from 62.1% to 38.4% (P < 0.001) compared to conventional hemodialysis.
