摘　　要：目的减少肿瘤患者在治疗过程中反复穿刺采取血标本的痛苦,确保从外周静脉插入的中心静脉导管(PICC)中取得的血标本所受干扰因素最小。方法将82位患者随机分为3组,分别从PICC导管处弃血1 m l、2m l和2.5 m l,采血标本进行血常规、血生化检查,与同时采集周围静脉的血标本进行对照。结果按照合理的采血路径从PICC导管中取血标本,3组检验结果经统计学处理均有差异(P<0.05),但是按照美国CLIA’88的规定是在实验室允许误差指标范围内。结论按照合理的采血路径从PICC导管处采取血标本进行血常规、血生化检查是可行的,且可以根据对检验结果精确性要求的不同选择不同的弃血量。Objective To reduce the suffering from repeating punctures required by frequent blood sample collection during the treatment for oncology patients;and to minimize the interference when drawing blood samples from PICC（ peripherally inserted central catheter）. Methods 82 patients were randomly divided into 3 groups. Blood of 1 ml, 2 ml, and 2.5 ml was abandoned respectively from PICC catheters. The complete blood count and biochemistry of blood samples were compared with the blood samples draw from routine peripheral veins at the same time. Results Taking blood sample through reasonable routes from PICC catheters, there was a difference among the 3 groups（ P 〈0.05 ）. But the difference was within the laboratory permitted discrepancy according to CLIA＇ 88 of US. Conclusion It is practical to take blood sampies through reasonable routes from PICC catheters to check the complete blood count and biochemistry. It is recommended to choose different abandoned blood volumes based on the different requirements of accuracy of test results.
