Abstract：Objective:To probe into the clinical application effect of arteriovenous puncture trocar used in blood purification.Methods:A total of 30 hemodialysis patients treated with mature fistula were selected,and each pa-tient received hemodialysis with ordinary internal fistula puncture needle (needle group)and internal fistula puncture trocar (soft needle group),10 times in each,then to observe and record the patients’pain and the limb activity when they were punctured by two kinds of puncture needles,their overall comfort during the treatment, the average value of arterial pressure and venous pressure before the pump,hemostatic time after withdrawal of needles,wound recovery,satisfaction to nurse puncture and the occurrence of puncture related adverse events in both groups.Results:The patients’punctured limb activity,overall comfort during the treatment,average value of arterial pressure and venous pressure before the pump,hemostatic time after withdrawal of needles,wound recovery and the occurrence of puncture related adverse events in soft needle group were all better than that in needle group,and the difference was statistically significant (P <0.05 );there was not statistically significant difference in puncture pain between both groups (P > 0.05 );the difficulty and total satisfaction of nurses in puncture in soft needle group were lower than that in needle group,but the satisfaction to decrease the potential danger of pricking wound in soft needle group was higher than that in needle group (P <0.05).Conclusion:He-modialysis arteriovenous trocar can increase the overall comfort of hemodialysis patients during the treatment and the activity of the punctured limb,decrease the incidence of puncture related adverse events and shorten the hemostatic time after withdrawal of needles.It is helpful for puncture wound recovery,and low pressure can en-sure adequate flow and dialysis effect in hemodialysis.We should pay attention to the related knowledge and op-eration skills training for nurses during clinical application.
