Abstract

Background: We sought to determine in vitro whether the PrisMax and CARPEDIEM hemofiltration and hemodialysis devices can reliably deliver ultrafiltration (UF) control that is sufficiently precise to treat infants.

Methods: We have previously measured the precision of UF control of the Prismaflex, Aquarius and NIDUS devices by in vitro testing with a bag of saline set up as a dummy patient, and comparing the differences between the UF set and displayed by the devices, and the actual fluid removal or addition measured by precise weighing. Here we have tested the PrisMax (updated version of Prismaflex) and the CARPEDIEM using the same method.

Results: The variances of the setting vs. actual errors, and display vs. actual errors after 15 min of 'treatment' with the PrisMax and CARPEDIEM were similar, but were significantly larger than in the NIDUS, and much smaller than in the Prismaflex. However, after a 4-h 'treatment session', the cumulative errors were still within ± 9 mL for these devices, compared with a maximum error of 2.6 mL in the NIDUS, and a deviation of -37.5 mL in the Prismaflex.

Conclusions: The PrisMax and the CARPEDIEM have adequate precision to be used in infants. The only device with UF error below 3 ml in 4 h is the volumetrically-controlled NIDUS. We recommend that regulatory bodies should introduce UF precision-testing for devices intended for use in infants.

婴儿血液滤过和血液透析装置超滤精度的体外测量,第2部分:PrisMax和CARPEDIEM与NIDUS、Prismaflex和Aquarius先前数据的比较
背景:我们试图确定PrisMax和CARPEDIEM血液过滤和血液透析装置是否能够可靠地提供足够精确的超滤(UF)控制来治疗婴儿。方法:我们之前通过体外测试,用一袋生理盐水作为假患者,测量了Prismaflex、Aquarius和NIDUS装置的UF控制精度,并比较了装置设置和显示的UF值与精确称重测量的实际液体去除或添加量的差异。这里我们用同样的方法测试了PrisMax (Prismaflex的更新版本)和CARPEDIEM。结果:PrisMax和CARPEDIEM“治疗”15分钟后的设置误差与实际误差、显示误差与实际误差的差异相似,但明显大于NIDUS,远小于Prismaflex。然而,在4小时的“治疗过程”后,这些设备的累积误差仍在±9 mL以内,而NIDUS的最大误差为2.6 mL, Prismaflex的偏差为-37.5 mL。结论:PrisMax和CARPEDIEM具有足够的准确性,可用于婴幼儿。唯一在4小时内UF误差低于3ml的设备是容量控制的NIDUS。我们建议监管机构对用于婴儿的器械引入UF精度检测。

期刊介绍: International Pediatric Nephrology Association Pediatric Nephrology publishes original clinical research related to acute and chronic diseases that affect renal function, blood pressure, and fluid and electrolyte disorders in children. Studies may involve medical, surgical, nutritional, physiologic, biochemical, genetic, pathologic or immunologic aspects of disease, imaging techniques or consequences of acute or chronic kidney disease. There are 12 issues per year that contain Editorial Commentaries, Reviews, Educational Reviews, Original Articles, Brief Reports, Rapid Communications, Clinical Quizzes, and Letters to the Editors.
