利多卡因凝胶无痛导尿对全身麻醉术后导尿的影响

Effect of painless catheterization with lidocaine gel on catheterization after general anesthesia

目的 探讨利多卡因凝胶无痛导尿对全身麻醉术后导尿的影响.方法 选择2016年1月至2017年6月本院于全身麻醉气管插管麻醉手术实施导尿术者90例,按照随机数字法分为两组,各45例.观察组使用利多卡因胶浆,对照组则行常规石蜡油润滑后置入患者尿道,导尿后1h及导尿后2h尿道疼痛程度比较,统计拔除气管导管后15 min内躁动分级.结果 观察组导尿后1h及导尿后2h,其尿道疼痛程度分别为（2.3±0.2）分和（1.6±0.1）分,均显著低于对照组的（4.3±0.3）分和（3.2±0.2）分,（t=37.210、48.000,P＜0.05）.观察组术后躁动分级为1级和2级例数分别为25例和15例,显著高于对照组的15例和10例（x2=12.462,P=0.000）.结论 对于全身麻醉术后导尿患者使用利多卡因凝胶,能有效的减少疼痛不适,降低尿道刺激症,减少躁动比例.

Objective To investigate the effect of painless catheterization with lidocaine gel on catheterization after general anesthesia. Methods 90 patients undergoing catheterization under general anesthesia for tracheal intubation at our hospital from January, 2016 to June, 2017 were divided into two groups （n=45） using random number method. The observation group was given lidocaine, while the control group was routinely lubricated paraffin oil into the urethra. 1 and 2 hours after catheterization, the urinary tract pain degrees were compared. The agitation grading 15 min after the removal of tracheal catheter was statistically generalized. Results In the observation group, the urinary tract pain degrees were （2.3 ± 0.2） points and （1.6 ± 0.1） points 1 and 2 hours after catheterization; which were signifcantly lower than those in the control group [（4.3 ± 0.3） and （3.2 ± 0.2）] （t = 37.210 and 48.000, P 〈0.05）. 25 cases had grade 1 agitation and 15 grade 2 in the observation group; and 15 and 10 in the control group （χ2 =12.462, P=0.000）. Conclusions Lidocaine gel for patients taking catheterization after general anesthesia can effectively reduce pain discomfort, urethral irritation, and the proportion of restlessness.
