不同回血量对高龄血液透析病人透析器残余血量的影响

目的 探讨不同回血方法对血液透析器内残余血量的影响,以尽量减少病人每次透析失血量.方法 采用自身对照法应用4种不同剂量的生理盐水回血方法回血,采集用于冲洗透析器的盐水,检测并计算出残血量,比较各组之间的差异.结果 应用生理盐水200ml回血方法及生理盐水250 ml所余的残余血量最少,具有统计学意义(P<0.01).但是后者的回血用盐水量较其他3组明显增多.具有统计学意义(P<0.01).结论 应用生理盐水200ml进行透析后回血,是目前最为可取的回血方法.

Comparative analysis of different return volume on dialyzer'' residual blood volume in elder patients

Objective To study influence of dialyzer' residual blood volume by using different return methods in elder patients, with the aim of decreasing the loss of blood in each dialysis in patients as less as possible. Methods four return blood doses indicated by four different saline solution amounts were studied by a self-comparison for a same patient. The residual blood volume was measured and calculated via collecting the salt water for washing dialyzer and the difference between the groups was compared. Results The residual blood volume was the least in the return blood method of 200ml blood return amount and 250ml salt water(P <0. 01 ). The difference between the groups was statistically significant. But the infusion of salt water in 250ml group was significantly more than other groups ( P < 0. 01 ). Conclusions It is the best choice that the return blood method of using 200ml salt water during dialysis.
