老年女性患者导尿管气囊注水量对留置效果的影响

The Role of Quantity of Saline Injected into Catheter Gasbag in the Effect of Indwelling Catheter in Old Female Patients

目的探讨老年女性患者留置导尿过程中,气囊注水量对留置效果的影响。方法将164例神经内科老年女性 需留置导尿患者(平均年龄74.18岁)随机分为对照组与观察组,各82例。观察组患者导尿管气囊内注入15～20 ml生理盐水固定,对照组气囊内注入生理盐水5～8ml。结果观察组溢尿率显著低于对照组(P<0.01),且留置导 尿管2周泌尿系感染(发热、混浊血性尿液、膀胱刺激征、尿道口异常分泌物等)发生率显著低于对照组(P<0.01)。 结论老年女性患者气囊导尿管注入15～20ml生理盐水,可有效地防止尿液外渗及导尿管脱出,减少泌尿系感染 率的发生,对临床留置导尿技术有指导意义。

Objective To explore the role of quantity of saline injected into catheter gasbag in the effect of indwelling catheter in the old female patients. Methods One hundred and sixty-four cases of old female patients (mean age 74.18 years old) who were indwelled catheter were divided randomly into observation group and control group. 15-20 ml saline was injected into catheter in observation group, while 5-8 ml saline in control group after urinary catheterization. The relationship between the indwelling time and the effect was observed. Results There was significant difference between two groups in the effect of indwelling catheter and incidence rate of urinary infection(all P< 0.01 ). Conclusion Injection of about 15-20 ml saline in catheter in the old female patient can protect the urethrorrhea and withdrawal of urethral catheter, and decrease the rate of infection in urinary system.
