Abstract:
Objective To explore the clinical application of blood return by tee union among central venous catheter ( CVC) in hemodialysis patients. Methods A total of 90 MHD patients had been selected and randomly divided into group A (opening blood return), group B (closing blood return), and group C (blood return by tee union) on average from August 2013 to July 2014 in Hemodialysis Center. We documented the length of blood return, the volume of 0. 9% sodium chloride solution, red-cell count ( RCC) in the residual liquid after dialysis, the change of C reactive protein at the beginning of treatment, 6 months and 12 months after treatment, and the rate of CVC relative infection ( CVC-RI) among three groups. Results The length of blood return were (291.04 ±46.92),(340.75 ±51.36), (278.99 ±45.21)s in A, B, C group, the volume of 0. 9% sodium chloride solution (186. 72 ± 27. 65),(257. 24 ± 40. 07),(191. 11 ± 32. 53) ml, the number of RCC in the residual liquid after dialysis (4 628. 4 ± 501. 6),(5 104. 5 ± 592. 7), (4 588. 2 ± 546. 9)/μl (F=3. 932 7,4. 529 1,3. 133 8;P<0. 05). Compared each two of three groups, the differences of each indexes between group A and group C were no statistically significant (P>0. 05), but the length of blood return in these two groups were shorter than that of group B (P<0. 05). After 6 and 12 months, the level of CRP in group B and C was lower than that of group A (P<0. 05);the different time point of CRP, it presented that it increased with the length of treatment in the group A (P <0. 05), but these of group B and C had no statistical significance at three time point (P>0. 05). The incidence rate of CVC-RI were 40. 00%, 16. 67%, 13. 33%in group A, B and C (χ2 =7. 080 7,P<0. 05);these of group B and C was lower than that of group A ( P<0. 05), but the statistical significance did not exist between group B and C (P >0. 05). Conclusions The CVC in hemodialysis patients utilized tee union for blood return which is simple, organized, saving time and labor, and reduced the potential risk of CVC-RI, slight infection symptom and the volume of sodium chloride solution.
