Это сделало возможным разработку устройств, в ходе диализа отслеживающих эффективность процедуры по реальному клиренсу с расчетом показателя Kt/V. Целью данной работы было изучение точности работы On-line Clearance Monitor (OCM - «Fresenius», Германия). Методы. Восьми стабильным диализным пациентам (4 женщины, 4 мужчины, средний возраст - 38 ± 2,2 г.) было проведено по 8 сеансов бикарбонатного гемодиализа. Использовались диализаторы с различными мембранами (Polysulfone Fresenius, Althane, Polysulfone Bellco, регенерированная целлюлоза). Для отслеживания показателя Kt/V применялся блок ОСМ в составе диализного аппарата «Fresenius 4008S». Данное устройство в ходе диализа периодически изменяет проводимость диализата и по показателям проводимости на входе и выходе в диализатор рассчитывает ионный диализанс, а по его величине - достигнутый на данный момент эффективный показатель Kt/V. Фаза измерения длится около 11 минут, после чего проводимость диализата возвращается к заданному значению. Данные, полученные по показаниям ОСМ, сравнивались с показателем Kt/V, рассчитанным на основе концентрации мочевины в пробах крови до диализа и в его конце (по однокамерной модели). Результаты. В подавляющем большинстве случаев показатель Kt/V, определенный ОСМ, был несколько ниже определенного по пробам крови. Обратная зависимость отмечалась только при большом (9% от сухой массы тела пациента) объеме ультрафильтрации (4 сеанса диализа). Средний Kt/V [OCM] составил 1,195 ± 0,04; средний Kt/V по пробам крови - 1,271 ± 0,04, что не выявило статистически значимой разницы. Отмечалась четкая парная корреляция данных показателей (r = 0,96; р &lt; 0,001). Определение Kt/V блоком ОСМ не зависело от типа диализатора. Заключение. Таким образом, блок ОСМ представляется надежным, простым и недорогим в использовании устройством, позволяющим в ходе диализа отслеживать его эффективность</p></abstract><trans-abstract xml:lang="en"><p>It is known that the ionic dialysance is equivalent to the blood water urea clearance. Thus, on-line Kt/V measurement can be a useful tool for verification of dialysis dose adequacy. The aim of this study was to verify the accuracy of the On-line Clearance Monitor device (OCM) with different dialysis membranes and its convenience in routine clinical work. Methods. 8 stable dialysis patients (4 M, 4 F, mean age 38 ± 2,2 years) were evaluated during 64 dialysis sessions with different membranes (Polysulfone Fresenius, Althane, Polysulfone Bellco, regenerated cellulose). OCM was incorporated into Fresenius 4008S dialysis machine. This device periodically varied inlet dialysate conductivity (CD) up and down by up to 17,5% from the setting value. The phase of change of CD lasts for a maximum of 60 sec. The CD variation was then followed by a phase of constant CD, and CD was measured at the dialysate inlet and outlet side. The total duration of the ionic dialysance measurement was approximately 11 min. After the measurement, the value of Kt/V is displayed. Blood urea samples were collected before and after each dialysis session (according to NKF-DOQI recommendation). Kt/V was calculated using the formula: Kt/V = -ln (R - 0,03) + (4 - 3,5 × R) × UF/W (Kt/V [Ur]). Results. Kt/V [Ur] was somewhat higher than Kt/V [OCM] in all cases, except for dialysis sessions with high ultrafiltration volume (9% of dry weight, N = 4). Mean Kt/V [OCM] was 1,195 ± 0,04; mean Kt/V [Ur] was 1,271 ± 0,04. The difference was not significant. There was high and significant correlation between these values (r = 0,96, р &lt; 0,001). Kt/V determination was independent of dialyzer’s type. We can conclude that Fresenius OCM is a reliable, simple and inexpensive non-invasive tool for optimization of the dialysis program in usual clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гемодиализ</kwd><kwd>программный гемодиализ</kwd><kwd>адекватность</kwd><kwd>ионный диализанс</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sargent J.A., Gotch F.A.
