目的  探讨基于互联网的智能握力器在促进血液透析患者自体动静脉内瘘(arteriovenous fistula，AVF)成熟中的应用效果研究。 方法  选择苏州大学附属第二医院2021年1月—12月收治的40例终末期肾病患者借助传统握力运动训练设为对照组，2022年1月—12月收治的30例患者借助基于互联网的智能握力器进行握力运动训练为研究组，对比2组AVF成熟率、首次使用时间、首次穿刺成功率及相关并发症，手术后握力运动训练的依从性。 结果 手术后4周研究组与对照组AVF临床成熟率  (χ2=1.542，P=0.228)、超声成熟率(χ2=0.420，P=0.517)对比无明显统计学差异；手术后8周研究组AVF临床成熟率(χ22=16.324，P＜0.001)、超声成熟率(χ2=12.343，P＜0.001)、静脉内径(t=8.358，P＜0.001)、肱动脉流量(t=8.320，P＜0.001)高于对照组，静脉距皮深度低于对照组(t=12.718，P＜0.001)，研究组患者AVF首次使用时间早于对照组(t=6.665，P＜0.001)，首次穿刺成功率高于对照组(χ2=13.611，P＜0.001)，AVF并发症发生率低于对照组(χ2=5.605，P=0.018)；研究组患者手术后握力运动训练依从性高于对照组(χ2=7.805，P=0.005)。 结论  基于互联网的智能握力器可缩短血液透析患者自体动静脉内瘘成熟时间，提升自体动静脉内瘘成熟率，保证患者的首次穿刺成功率，降低血液透析患者自体动静脉内瘘并发症发生率，提高其握力运动训练依从性。

Objective  To study the application effect of internet-based intelligent gripper to promote maturation of autologous arteriovenous fistula (AVF) in hemodialysis patients.  Methods  A total of 40 patients with end-stage renal disease were recruited and assigned to control group that used traditional grip strength exercise training in The Second Affiliated Hospital of Suzhou University during January 2021 to December 2021; a total of 30 patients using the internet-based intelligent gripper strength training were assigned to research group from January 2022 to December 2022. Maturation rate of the AVF, first puncture time, success rate of the first puncture, puncture complication, and compliance with postoperative grip strength exercise training were compared between the two groups. Results After the surgery for 4 weeks, clinical maturation rate (χ²=1.542, P=0.228) and ultrasound maturation rate (χ²=0.420, P=0.517) had no significant differences between the two groups. After the surgery for 8 weeks, clinical maturation rate (χ²=16.324, P<0.001), ultrasound maturation rate (χ²=12.343, P<0.001), venous diameter (t=8.358, P<0.001), and brachial artery flow   (t=8.320, P<0.001) were higher in research group than in control group, and the depth from vein to skin was lower in research group than in control group (t=12.718, P<0.001). In research group, the first use of the AVF was earlier (t=6.665, P<0.001), the success rate of the first puncture was higher (χ²=13.611, P<0.001), the complication rate was lower (χ²=5.605, P=0.018), and the compliance rate with postoperative grip exercise training was higher (χ²=7.805, P=0.005), as compared those with control group.  Conclusion Internet-based intelligent gripper training can shorten the maturation time of AVF, improve the maturation rate of AVF, ensure success rate of the first puncture, reduce the incidence of complications, and improve the compliance with grip exercise training in hemodialysis patients.
