探讨尿液pH值变化对导尿引起尿道感染的影响

Impact of change of urine pH on urinary tract infections due to urethral catheterization

目的探讨通过护理措施改变尿液pH值,观察尿液pH值的变化对导尿相关尿道感染的影响。方法将80例尿检阳性的骨科术后患者,随机分成试验组和对照组,两组患者在年龄、性别、手术、营养、住院天数、抗菌药物用量及疗程、留置导尿时间差异均无统计学意义;对照组按常规护理措施进行治疗,试验组在常规护理的基础上增加饮食控制、膀胱冲洗液的变化及尿道口护理后温清水冲洗;比较两组患者尿道感染的疗效。结果试验组的治疗有效率为82.5%,对照组有效率为52.5%,两组差异有统计学意义(P<0.05)。结论通过护理措施使患者尿道呈弱碱性环境,可以抑制细菌增长,从而提高尿道感染的治疗效果。

OBJECTIVE To make the change of urine PH through nursing care procedures and observe the relationship between the change of urine PH and catheter-related urinary tract infections.METHODS A total of 80 bacteriuria positive patients who underwent orthopedic surgery were divided into experimental and control groups randomly,there were no significant difference in the age,sex,surgery,nutrition,length of stay,antimicrobial drug use,treatment and catheterization time between the two groups;the control group was treated by routine nursing care,the experimental group underwent diet control and bladder washing after washing of the urinary meatus with warm water besides routine nursing care;the clinical efficacy of the urinary tract infections between the two groups was compared.RESULTS The therapeutic effect of the experimental group was better than that of the control group,the difference was statistically significant（P〈0.05）.CONCLUSION To keep the urinary tract under alkalescent environment through nursing care procedures can inhibit bacterial growth,which therefore can help to improve the therapeutic effect of urinary tract infections.
