Spontaneous continuous arteriovenous hemofiltration (CAVH) may fail to control azotemia in small patients with renal failure due to poor blood flow. To produce adequate ultrafiltrate a continuous negative pressure was added to the ultrafiltrate line. Two hemofilter systems of different membrane and surface area were used. Suction support approximately doubled ultrafiltration rate in both hemofilters. No side effects such as severe hypotonia or early hemofilter clotting occurred. Added suction can serve as a useful support of spontaneous CAVH in children with renal failure and too poor a blood flow to control azotemia.
对于因血流不佳导致肾衰竭的小儿患者，自发性持续动静脉血液滤过（CAVH）可能无法有效控制氮质血症。为了产生足够的超滤液，在超滤液管路中添加了持续负压。使用了两种不同膜和表面积的血液滤过器系统。在两种血液滤过器中，负压支持使超滤率增加了约一倍。未出现严重低血压或血液滤过器早期凝血等副作用。对于患有肾衰竭且血流过差而无法控制氮质血症的儿童，增加负压可作为自发性CAVH的有效辅助手段。
