腹膜透析超滤衰竭诊断与治疗

Ultrafiltration failure in peritoneal dialysis: diagnosis and therapy

超滤衰竭是腹膜透析常见合并症,主要原因除与饮食及透析处方不当有关外,与腹膜功能亦有较大关系。诊断上除须排除导管相关性因素外,应及时行腹膜平衡试验(PET)了解腹膜功能,根据腹膜功能特点制定透析处方。治疗的关键在于严格把握机体容量平衡,量出为入。必要时可使用高渗透析液增加液体超滤。

Ultrafihration failure （UFF）, continues to be major complication of peritoneal dialysis （PD）. Its main reason is dysfunction of peritoneal, and it also relates to diet and dialysis prescription. Diagnosis of UFF is according to peritoneal equilibration test for assessing peritoneal function, and excluding peritoneal dialysis catheter-related factors. Enaction dialysis prescription is according to peritoneal function. Keypoint of therapy is precision control capacity balance. If necessary, using hyperosmotic dialysate increases peritoneal uhrafiltration.
