利多卡因在男性痔手术后尿潴留患者无痛导尿中的应用

Application of Painless Catheterization by Lidocaine Hydrochloride in Male Patients with Urinary Retention after Hemorrhoid Surgery

目的探讨2%盐酸利多卡因在男性痔手术后尿潴留患者无痛导尿中的应用效果。方法将60例痔手术尿潴留的男性患者随机分为两组:对照组用常规导尿方法;实验组患者先行利多卡因尿道口湿敷、利多卡因涂管后再进行导尿。比较两组患者导尿过程中的疼痛程度、尿道黏膜损伤情况及置管后的尿路刺激症状。结果实验组患者导尿过程中的疼痛程度、导尿后的尿道黏膜损伤程度及尿路刺激症状等均轻于对照组,差异有统计学意义(P<0.01)。结论利多卡因可明显减轻男性患者导尿过程中的疼痛和尿道黏膜的损伤,且能缓解置管后尿路刺激症状,提高患者的舒适度。该方法价格低廉、使用时操作简单,尤其适合在基层医疗服务部门推广应用。

Objective To explore the effect of painless catheterization by lidocaine hydrochloride in male patients with urinary retention after hemorrhoid surgery.Methods Sixty patients with urinary retention after hemorrhoid surgery were randomized into the two groups：control group with the conventional method of urethral catheterization and experimental group with 2% lidocaine hydrochloride soak in the urethral orifice and catheter coat by lidocaine for urethral catheterization.Comparisons were conducted on pain,urethral mucosa damages and urinary irritation symptoms in the process of catheterization between the two groups.Results The severity levels of pain,mucosa damage and urinary irritation symptoms were significantly lower in the experimental group than those in the control group（P0.01）.Conclusion Lidocaine can relieve the pain in the process of catheterization,reduce the urinary mucosa damage,alleviate the urinary irritation symptoms and improve the comfort of patients.The operation is simple and economic,which is particularly suitable for application in basic-level medical units.
