摘要：目的：探讨自体血回收过程中吸引器负压控制与患者出现血红蛋白尿之间的关系。方法：将54例符合自体血回收条件且术中回输自体血超过1000ml患者随机分成三组，吸引器负压分别调节为100 mmHg(A组)、150 mmHg(B组)、200 mmHg(C组)。观察各组患者在输入回收自体血500ml和1000ml时，尿液颜色是否有变化。结果: C组患者在回输自体血超过1000ml时，出现血红蛋白尿的例数明显多于A组和B组患者，差异有显著性。结论：在进行术中血液回收时，吸引器负压以控制在150 mmHg左右为佳，既可保证工作效率，有利于抢救患者生命，又能降低患者因红细胞受损而导致血红蛋白尿的发生率。

    Abstract： Objective: To explore the relation of attractic controlment with negative pressure and happen rate of hemoglobinuria during reclaiming the blood of operational patient. Method: 54 cases were divided into 3 groups. The different negative attraction pressure are 100mmHg(Group A), 150mmHg(Group B) and 200mmHg(Group C). Then observed the change of urine colour . Result: Hemoglobinuria cases of Group C more than Group A and Group B. Conclusion: Negative attraction pressure with 150mmHg is the best. It not only improves the work efficiency , but also reduces happen rate of hemoglobinuria. ......
