目的:血液透析结束后使用自行研制带排气调节阀的止血气垫用于压迫止血，并评价临床使用效果。方法:选取2019年5—10月在吉林大学第一医院血液净化中心行规律血液透析治疗的自体动静脉内瘘患者50例，采用随机数字表法分为试验组和对照组各25例，透析后试验组使用自制带排气调节阀的止血气垫压迫止血，对照组使用纱布块压迫止血。比较2组完全止血时间、压块移位、出血、血肿发生情况及操作便利性。结果:对照组完全止血时间为（36.37 ± 2.12）min，试验组为（20.52 ± 3.65）min，2组比较差异有统计学意义（n t值为83.695，n P<0.01）；对照组压块移位、出血、血肿发生率分别为5.20%（26/500）、13.60%（68/500）、3.00%（15/500），试验组分别为0、8.20%（41/500）、0，2组比较差异有统计学意义（n χ2值为7.506，均n P<0.01)；对照组单手操作率为44.00%（220/500），试验组为98.00%(490/500），2组比较差异有统计学意义（n χ2值为354.055，n P<0.01）。n 结论:将带排气调节阀的止血气垫应用于自体动静脉内瘘患者拔针后促进止血，止血效果好，操作简单便利，值得临床推广。“,”Objective:To evaluate the clinical effect of hemostatic air cushion with exhaust control valve for compression hemostasis after hemodialysis.Methods:From May to October 2019, 50 patients with autogenous arteriovenous fistula who underwent regular hemodialysis in the blood purification center of the first hospital of Jilin University were selected and randomly divided into two groups. After dialysis, self-made hemostatic air cushion with exhaust adjustment (experimental group) and gauze block compression hemostasis (control group), 25 cases in each group. The complete hemostasis time, compression displacement, bleeding, hematoma incidence and the convenience of single hand operation were compared between the two groups.Results:The complete hemostasis time of the control group was (36.37±2.12) min, and that of the experimental group was (20.52±3.65) min, the difference was statistically significant (n t value was 83.695, n P<0.01). The incidence of displacement, hemorrhage and hematoma in the control group were 5.20% (26/500), 13.60% (68/500) and 3.00% (15/500) respectively, and those in the experimental group were 0, 8.20% (41/500) and 0 respectively, and the differences between the two groups were statistically significant (n χ2 value was 7.506, n P<0.01). The one hand operation rate of the control group was 44.00% (220/500), and that of the experimental group was 98.00% (490/500). The difference between the two groups was statistically significant (n χ2 value was 354.055, n P<0.01).n Conclusions:The hemostatic air cushion with exhaust regulating valve is applied to patients with autogenous arteriovenous fistula after needle extraction, which has good hemostatic effect, simple and convenient operation, and is worthy of clinical promotion.
