To date, little emphasis has been placed on the impact of different biocontrols in achieving high replacement volumes. The aim of the present study was to compare the substitution volume achieved with three different monitors using the three available automatic systems. Methods: Prospective, observational cross-over study of prevalent patients on post-dilution OL-HDF. Each patient underwent 9 consecutive post-dilution OL-HDF sessions with each of the monitors included in the study: Artis, 6008, and Surdial X with the corresponding biocontrols: UltraControl, AutoSub+, and Max-Sub, respectively. After each session, the final convective volume and other parameters related to HD and medium-molecule clearance were collected. Results: Thirteen patients were included (57% male, age 62 \u00b1 14 years), of whom 71% were dialyzed via an arteriovenous fistula. The mean time on dialysis was 51 \u00b1 32 months. Convective volume achieved with Max-Sub biocontrol (Surdial X monitor) was higher than that achieved with UltraControl biocontrol (Artis monitor) (31 \u00b1 2 vs. 29.4 \u00b1 2.2 L\/session, p = 0.009) and AutoSub+ biocontrol (6008 monitor) (31 \u00b1 2 vs. 28.9 \u00b1 2.6 L\/session, p = 0.01). On multivariate analysis, factors associated with higher convective volume were the prescription of Max-Sub biocontrol (B 1.61, 95% CI [0.41\u20132.80], p = 0.009), TPM (B 0.02, 95% CI [0.01\u20130.03], p = 0.018), blood processed (B 0.17, 95% CI [0.08\u20130.26], p &lt; 0.001), and not having diabetes mellitus (B \u22121.66, 95% CI [\u22122.72 to 0.59], p = 0.002). Conclusion: The volume achieved by convective transport can vary according to the type of biocontrol, with Max-Sub performing the best out of the 3 biocontrol systems.
