ABSTRACT
Objective To improve the efficiency of blood collection in hemodialysis patients by inventing and applying new blood collection needles.Methods One hundred and eighty cases of hemodialysis patients were randomly divided into control group 1(CG1),control group 2(CG2),experimental group(EG). Comparison of the three groups in time of blood collection,the number of operation that had the risk of acupuncture injury and the number of the blood samples that had been contaminated. Results There were statistically significant difference (P<0.05)in three groups.The number of times of blood collection in the number of operations that had the risk of acupuncture injury,and the number of the blood sample that had been contaminated. CG1 had the longest blood collection time(12.55 min),EG had the shortest blood collection time(5.09 min);the risk of acupuncture injury was the highest in CG2 and the lowest in the EG.The number of contamination of blood samples and the amount of inaccurate sample in CG1 were the highest,and the lowest in the EG. Conclusions The working efficiency of transfer type anti-acupuncture needle(TTAN)during blood sample collection in hemodialysis patients is signifi-cantly better than that of traditional blood collection method,and it is helpful to reduce the risk of acupuncture injury and the risk of contamination in blood samples,which is worthy of promotion.
