Abstract：Objective To observe the application effect of closed automatic-exhaust pipeline pre-rinse method in hemodialysis patients.Methods 71 cases of hemodialysis patients from Hainan provincial people's hospital were collected. By using the self-control study, they were divided into control group and experimental group. Control group used conventional closed pipeline pre-rinse while experimental group used closed automatic-exhaust pipeline pre-rinse. Pre-rinse operation time and dialyser coagulation of the two groups were compared. Urea clearance index Kt/V in two groups of 32 patients who used dialysis machine with on-line urea clearance index monitoring function (arranged according to the admission time) were calculated and compared. 20 patients were randomly selected to compare removal effect of particulate matter in extracorporeal blood circulation pathway.Results Pre-rinse operation time in experimental group was (221.69±10.44) s which was less than control group (367.88±16.68) s, the difference was statistically significant (t=75.05, P<0.001). Coagulation grade of dialyser between the two groups had no statistically significant difference (Z=-0.16,P=0.87). Urea clearance index Kt/V in experimental group was (15.08±1.53) and control group was (15.03±1.55), the difference was no statistically significant (t=-0.31,P=0.76). Number of particulate matter >10μm and >25 μm in extracorporeal blood circulation pathway between the two groups were compared, and the difference was not statistically significant.Conclusions For hemodialysis patients, closed automatic-exhaust pipeline pre-rinse maybe a time saving and power saving, safe and effective method, worthy to popularize and apply in clinic.
