气囊微充盈状态合用丁卡因胶浆在男性患者拔出双腔尿管中的应用

APPLICATION OF SLIGHTLY FILLING AEROCYST COMBINED THE USE OF TETRACAINE MUCILAGE IN EXTUBATION OF DUBLE-CAVA URETHRAL CATHETER IN MALE PATIENTS

目的:探讨拔除男性患者双腔尿管的最佳方法。方法:将100例留置双腔尿管的男性患者随机分为实验组和对照组各50例,对照组按常规消毒外阴,用注射器抽出气囊内全部生理盐水,轻轻地将尿管拔出。实验组在拔导尿管前提起阴茎将2ml丁卡因胶浆从尿道口滴入,保留3～5分钟,再用20ml注射器将针头插入双腔尿管的注水管端,不回抽,使气囊中的水通过压力自动排入注射器内,未见液体流出后再轻轻地将尿管拔出。此方法拔出的尿管气囊呈微充盈状态,内有余液约0.5ml。观察比较两组患者拔管时疼痛和排尿情况,并进行统计学分析。结果:实验组排尿疼痛和尿潴留发生率明显低于对照组,P<0.01,差异具有统计学意义。结论:气囊微充盈状态合用丁卡因胶浆拔出男性患者双腔尿管能减轻患者痛苦,降低继发性尿潴留的发生率。

Objective： To explore the best extubation method of double-cava urethral catheter for male patients. Methods：100 male patients with indwelling double-cava urethral catheter were divided into test group and control group randomly, each including 50 cases. The control group underwent vulvar disinfection and mildly extubated the urinary canal when the physiological saline inside the capsule was fully taken out. The test group＇s mentula were raised before extubating and 2ml of tetracaine mucilage was dropped into urethra, retained for 3-5 minutes, then inserted the needle of 20ml syringe into the affusion canal of double-cava urethral catheter, no pumpback,allowing the liquid to flow into the syringe automatically by the pressure in the aerocyst, extubated the urinary canal when flow stopped. The urinary canal aerocyst of this method was slightly filling, with about 0.5 ml of liquid remained. The pain and urination condition were observed and compared, then the data was statistically analyzed with SPSS 10.0.Results：The test group＇s pain rate and uroschesis rate were significantly lower than the control group＇s （P〈0.01）.Conclusion：To extubate the double-cava urethral catheter with aerocyst slightly filling combined with the use of tetracanine mucilage, could relieve the suffering and decrease the incidence rate of secondary uroschesis.
