[Kinetic modeling during continuous hemodiafiltration in patients with sepsis and multiorgan failure].
Kinetic simulation in terms of urea and creatinine is the best way of prescribing a dialysis dose and assessing its quality as it considers differences in a patient's body weight, the level of catabolism, the rate of equilibration, including the recirculation phenomenon noticeably observed under shock. A 2-pool model of distribution of urea and creatinine was employed in the study. The latter was carried out in 31 patients (17 males and 14 females) with sepsis and multi-organ failure receiving 50 sessions of continuous hemodiafiltration (CHDF). The mean duration of CHDF was 73.8 +/- 7.0 (4.0-207.0) hours, the daily volumes of a substitute, a dialysate, and an effluent (filtrate + dialysate) were 33 +/- 1.0 (5.0-60.0), 43.9 +/- 0.8 (2.6-62.0), and 80.4 +/- 1.6 (12.0-122.3) liters a day, respectively. An analysis confirmed the high efficiency of CHDF close to that of the daily volume-body weight ratio and showed that such conditions of the procedure are optimal in maintaining azotemia at the subnormal level irrespective of the degree of cababolism.
