利多卡因在急诊室导尿中的应用

The Application of Lidocaine in Catheterization in Emergency Room

目的比较急诊室两种不同导尿方法的效果。方法选取急诊需导尿患者102例,按就诊时间的奇偶日期随机分为对照组与实验组(利多卡因局麻加石蜡润滑剂)。结果实验组收缩压、舒张压、心率与术前10min比较,差异无统计学意义;对照组收缩压、舒张压、心率与术前10m in比较,差异有统计学意义。两组患者插管时疼痛程度比较,差异有统计学意义。两组病人一次置管成功率和插管时间比较,差异有统计学意义。结论尿道内灌注利多卡因局麻加液体石蜡润滑剂的导尿方法,可减轻刺激引起的应激反应、提高导尿成功率、减轻患者痛苦,更易被患者接受。

Objective To examine the effect of two different catheterization methods used in emergency room.Methods 102 emergency patients who need catheterization were divided into two groups according to the parity date when they were admitted to hospital.The experimental group was given lidocaine and liquid paraffin lubricant in the process of catheterization while the control group was given liquid paraffin lubricant only.Results Systolic blood pressure（SBP）,diastolic blood pressure（DBP）,heart rate（HR） in experimental group remained stable compared to that at 10 minutes prior to the catheterization,while that in control group changed significantly.Moreover,the difference between the experimental and control group is also significant.The pain score in the process of catheterization in both groups were tested by Rank sum test,and the difference was significant.Tested by x2 test,the catheter one time success rate and intubation time in each group differed to each other significantly.Conclusion The catheterization method that perfuse lidocaine and liquid paraffin lubricant into urethral can reduce stress responses,improve the success rate of catheterization,decrease the pain score in catheterization,so are more likely to be accepted by patients.
