【摘要】连续性肾脏替代治疗过程中可能会出现多种并发症，其中低磷血症的严重不良后果与高发生率导致连续性肾脏替代治疗(continuous renal replacement therapy，CRRT)相关的低磷血症成为一个亟待解决的问题。回顾有关CRRT 患者低磷血症的文献，综述了进行CRRT 相关的低磷血症的的潜在危险因素、血磷水平对疾病程度和死亡风险的识别以及磷酸盐补充策略和成本效益分析，并提供补充策略的相关建议建议，旨在为医护人员预防、干预CRRT相关的低磷血症提供参考和依据。

【Abstract】A variety of complications may happen in the processes of continuous renal replacement therapy (CRRT). Hypophosphatemia is a CRRT- related complication with higher incidence and serious consequences, and is becoming a critical issue to be solved. This paper reviews the literature about hypophosphatemia in CRRT patients, potential risk factors for CRRT-related hypophosphatemia, correlation of blood phosphorus level with the disease degree and death risks, and suggestions about phosphate supplement strategies and cost-effect analysis, in order to provide the useful information for medical staff to prevent and intervene CRRT-related hypophosphatemia.
