摘　　要：目的 探讨在连续性血液净化治疗中指导超滤量调节的最佳评价指标。方法 监测15例危重患者在连续性血液净 化治疗中的中心静脉压、平均动脉压。通过比较在不同指标下调整超滤量后液体管理的效果,评价中心静脉压对反映患者容 量状况的敏感性。结果 比较发现,15例患者中心静脉压与超滤量之间的相关系数为-0．2624,比平均动脉压与超滤量的相 关系数(-0．05)高,两者差异有显著性意义(P<0．05)。结论 连续性血液净化治疗中,监测中心静脉压来评估患者容量状 况较平均动脉压更为敏感,为实现个体化的液体管理提供了更为可靠的指标。Objective To find out a better evaluation indicator to adjust ultrafiltration volume during blood purification. Methods From March to October in 2004, central venous pressure and mean arterial blood pressure of 15 serious patients were measured as indicators to adjust ultrafiltration volume during hemodialysis. The effectiveness of adjusting ultrafiltration volume according to different indicators on the management of blood volume had been compared, and the sensibility of monitoring central venous pressure to reflect patients＂ volume status was assessed. Results The correlation coefficient（-0. 2624） between central venous pressure and ultrafiltration volume was significantly higher than that between mean arterial blood pressure and ul- trafiltration volume（-0.05）. Conclusion During continuous blood purification, central venous pressure was found to be more sensitive than mean arterial blood pressure for the evaluation of the volume status. And monitoring central venous pressure could provide a more exact and reliable indicator for individual liquor management.
