Abstract: ObjectiveTo explore the clinical effects of button blunt needle puncture method in preventing fistula complication in patients with hemodialysis. Methods 40 cases of the patient in blood purification center were selected and divided into 2 groups. Observation group (20 cases ) was applied blunt button needle puncture and the comparison group (20 cases) was treated with sharp button needle puncture method. Three months later, theresults of hemstatic time, false aneurysm, puncture point ooze blood rate and pain of the two groups’ patients were compared. Results The observation group’s hemstatic time, false aneurysm, puncture point ooze blood rate and pain were obviously lower than that of the comparison group (P<0.05). Conclusion The method of blunt button needle puncture can relieve the patients’ pain and fistula complication incidence by repeated sharp button needle puncture and extend the service life of fistula so as to improve the patients’ life quality. The high practicability of blunt button needle puncture is worthwhile popularized in the clinical application.
