摘要

背景:我们比较了用2池动力学模型预测的磷酸盐去除与其他报道的用过的透析液中测量的磷酸盐去除。方法:对35组患者进行了26项研究,报告了磷酸盐去除。在几乎所有的研究中,患者透析时间接近4小时(范围为3至6小时)。在每项研究中,透析前血清磷酸盐、体型、透析器K0 A尿素、血液和透析液流速以及透析时间长度的组平均值被输入到动力学模型中。预测组平均磷酸盐去除和透析后血清磷酸盐与报告的测量值进行比较。结果:平均(按患者组)预测磷酸盐去除率为931±170 mg/次,略高于(p)。结论:对于常规4小时透析治疗,2池动力学模型预测的磷酸盐去除率和透析后血清磷酸盐值与报道的实测值相似。

Comparison of modeled versus reported phosphate removal and modeled versus postdialysis serum phosphate levels in conventional hemodialysis.

Background: We compared predictions of phosphate removal by a 2-pool kinetic model with measured phosphate removal in spent dialysate as reported by others.

Methods: Twenty-six studies were identified that reported phosphate removal in 35 groups of patients. In almost all studies, patients were dialyzed for close to 4 h (range 3 to 6 h). For each study, group mean values of predialysis serum phosphate, body size, dialyzer K0 A urea, blood and dialysate flow rates, and session lengths were input into the kinetic model. Predictions of group mean phosphate removal and postdialysis serum phosphate were compared with reported measured values.

Results: Mean (by patient group) predicted phosphate removal was 931 ± 170 mg/treatment, somewhat higher (p < 0.001) than the reported measured value, 900 mg ± 287. The ratio of predicted/measured removal averaged 1.15 ± 0.427. In 5/35 patient groups (3/26 studies) the predicted/measured phosphate removal was greater than 1.50. If these groups were excluded, the mean measured phosphate removal was 990 mg versus 966 predicted, with a ratio of predicted/measured removal averaging 0.993. Measured group mean postdialysis serum phosphate values (reported in 25/35) were 2.64 ± 0.54, not significantly different from predicted (2.60 ± 0.24 mg/dl, p = NS).

Conclusions: For conventional 4-h dialysis treatments, phosphate removal and postdialysis serum phosphate values predicted by a 2-pool kinetic model are similar to reported measured values.

期刊介绍: Seminars in Dialysis is a bimonthly publication focusing exclusively on cutting-edge clinical aspects of dialysis therapy. Besides publishing papers by the most respected names in the field of dialysis, the Journal has unique useful features, all designed to keep you current: -Fellows Forum -Dialysis rounds -Editorials -Opinions -Briefly noted -Summary and Comment -Guest Edited Issues -Special Articles Virtually everything you read in Seminars in Dialysis is written or solicited by the editors after choosing the most effective of nine different editorial styles and formats. They know that facts, speculations, ''how-to-do-it'' information, opinions, and news reports all play important roles in your education and the patient care you provide. Alternate issues of the journal are guest edited and focus on a single clinical topic in dialysis.
