摘要目的 探讨牵引法用于预防老年患者留置导尿漏尿的适宜牵引重量,为临床工作提供理论依据.方法 采用方便取样法选取扬州大学医学院附属江都人民医院老年科2014年1月—2016年8月留置导尿漏尿患者120例,随机分为4组,使用牵引法预防漏尿,分别采用50、100、150、200 g的牵引重量,比较4组漏尿预防效果和患者舒适情况.结果 50 g牵引重量的预防漏尿有效率为16.7%,100、150、200 g牵引重量的预防漏尿有效率均为100%,4组不同牵引重量预防留置导尿漏尿的效果差异有统计学意义(Hc=73.849,P<0.001),两两比较显示100 g组、150 g组、200 g组的效果明显优于50 g组(χ2=42.857,P<0.001).4组不同牵引重量患者舒适度差异有统计学意义(Hc=57.674,P<0.001).200 g牵引重量造成患者中、重度不适发生率达70%,与150 g牵引重量相比,差异有统计学意义(χ2=19.817,P<0.001);150 g牵引重量与100 g牵引重量造成患者中、重度不适发生率比较,差异无统计学意义(χ2=0.162,P=0.688).结论 100~150 g是老年留置导尿患者预防漏尿最适宜的牵引重量.

abstractsObjective To explore the appropriate traction weight of traction method for the prevention of leakage of urine in elderly patients with indwelling urethral catheterization so as to provide a theoretical basis for clinical work.Methods A total of 120 indwelling urethral catheterization patients with leakage of urine in department of geriatrics of Jiangdu People's Hospital of Yangzhou (affiliated Hospital of School of Medicine, Yangzhou University) were selected by convenient sampling from January 2014 to August 2016. They were randomly divided into four groups and accepted traction method for the prevention of leakage of urine involving traction weight with 50, 100, 150, 200 g. The preventive effect and situation of comfort of patients were compared among four groups.Results The effective rate in prevention of leakage of urine of traction weight with 50, 100, 150, 200 g was 16.7%, 100%, 100%, 100% with a statistically significant difference among four groups with different traction weight (Hc=73.849,P<0.001). The results of intercomparsion showed that the effects of groups with traction weight of 100, 150, 200 g were statistically better than that of the group with traction weight of 50 g (χ2 = 42.857,P<0.001). There were statistically significant differences in degree of comfort among four groups with different traction weight (Hc=57.674,P<0.001). Compared with the group with traction weight of 150 g, the incidence of moderate or severe discomfort was 70% in the group with traction weight of 200 g with a significant difference (χ2=19.817,P<0.001). There was no statistically significant difference in the incidence of moderate or severe discomfort between the group with traction weight of 100 g and 150 g (χ2= 0.162,P=0.688).Conclusions The optimum traction weight for the prevention of leakage of urine in elderly patients with indwelling urethral catheterization is 100-150 g.
