ABSTRACT
Objective To test the influence of peripherally inserted central catheter ( PICC) phlebotomizing and venipuncture ( VP) phlebotomizing on detection of coagulation function, so as to comfirm the feasibility of PICC. Methods Took 2 blood samples from the same patient, and divided the blood samples in to the PICC group and the VP group according to the methods of phlebotomizing to adopt a parallel controlled trial. Pearson correlation analysis and Bland-Altman analysis were taken during the following research. Results The 5 items of blood coagulation indexes testing showed that the results of PICC group and VP group were highly correlated, and the correlation coefficient was 0. 990 to 0. 997. The mean biases obtained by Bland-Altman analysis were closer to 0. Conclusion PICC and traditional method of VP showed obvious correlation and accordance in terms of the 5 indexes of coagulation function detection, which indicated that PICC is feasible for coagulation function detection.
