摘　　要：目的:探讨针尖斜面向下穿刺动静脉内瘘的可行性。方法:随机选取20例维持性血液透析患者,采用自身前后对比的方法,每人针尖斜面向下穿刺10次,传统针尖斜面向上穿刺10次,两种方法隔次采用,每次检测并记录动脉端、静脉端和外周血尿素氮,计算再循环率,并测量、记录患者的尿素清除指数(K t/v)。结果:针尖斜面向下穿刺动静脉内瘘的再循环率、透析充分性、穿刺成功率与传统的针尖斜面向上穿刺比较差异无统计学意义(P>0.05)。结论:采用针尖斜面向下穿刺动静脉内瘘行血液透析可避免血液通路再循环发生,值得临床推广应用。Objective： To study the feasibility of internal arteriovenous fistula puncture with needle bevel downward. Methods： Each of the randomly selected 20 patients with maintaining hemodialysis was respectively given puncture with needle bevel downward for 10 times and with needle bevel upward for 10 times by alternation. The self - control method was used to monitor and record the arterial and venous end and peripheral blood urea nitrogen, calculating recycling rate. Clearance indices of urea （ Kt / V ） were measured and recorded. Results ： There were not statistically significant differences in the comparison of recycling rate, dialysis sufficiency and success rate of puncture between the puncture with needle bevel downward and puncture with needle bevel upward （ P 〉 0.05 ）. Conclusion ： The internal arteriovenous fistula puncture with needle bevel downward can avoid the oc- currence of recirculation of blood access in hemodialysis and it is worthy of being applied in clinic practice.
