摘要目的 通过对扣眼穿刺角度架辅助扣眼穿刺建立隧道的效果进行探讨,为扣眼穿刺角度架在扣眼穿刺中的应用提供理论支持.方法 选取湖南省师范大学第一附属医院、湖南省人民医院血液净化室以动静脉内瘘为血管通路的维持性血液透析患者共38例,扣眼穿刺角度架辅助扣眼穿刺组19例,常规徒手扣眼穿刺组19例,观察两组患者隧道形成所需锐针穿刺次数和隧道形成后钝针穿刺一次到位率,应用长海痛尺疼痛评估量表评估两组患者在隧道形成后钝针穿刺时穿刺疼痛感.结果 扣眼穿刺角度架辅助扣眼穿刺组较常规徒手扣眼穿刺组隧道形成所需锐针穿刺次数明显减少(6.63±1.46 vs 8.42±1.80,P＜0.01),隧道形成后钝针穿刺有较高的一次到位率(93.71％ vs 84.61％,P＜0.01),隧道形成后钝针穿刺时穿刺疼痛感明显降低(1.92±0.68 vs 2.49± 0.66,P＜0.01).结论 扣眼穿刺角度架辅助穿刺能明显减少建立隧道时所需锐针穿刺次数,显著提高钝针穿刺一次到位率,明显较低钝针穿刺时患者的疼痛感.

abstractsObjective To investigate the clinical effect of the buttonhole technique angle frame in establishing track,and to provide theoretical basis for the use of buttonhole technique angle frame in the buttonhole technique.Methods A total of 38 maintenance hemodialysis patients with arteriovenous fistula for vascular access were randomized to the buttonhole technique angle frame aided group (n =19) or the common manual buttonhole technique group (control group,n =19).The number of cannulations with sharp needle in the phase of track formation,the rate of successful single cannulation with dull needle in the maintenance phase,and the scores of cannulation pain assessed with Changhai pain scale were observed.Results Compared with the control group,the number of carmulation with sharp needle in the phase of track formation reduced significantly in the angle frame aided group (6.63 ± 1.46 vs 8.42 ± 1.80,P ＜ 0.01).Compared with the control group,there were significantly higher rates (93.71％ vs 84.61％,P ＜ 0.01) of successful single cannulation with dull needle in the maintenance phase,and significantly lower scores(1.92± 0.68 vs 2.49± 0.66,P ＜ 0.01) of cannulation pain assessed with Changhai pain scale were observed in the angle frame aided group.Conclusions The buttonhole technique angle frame aided buttonhole technique may reduce the number of cannulation with sharp needle in the phase of track formation,increase the rate of successful single cannulation with dull needle in the maintenance phase,and reduce the pain of cannulation with dull needle.
