The comparative study of lidocaine and tetracaine urethral surface anesthesia in catheter related bladder discomfort of male patients after thoracoscopy surgery / 实用医学杂志

ABSTRACT

Objective To compare the effects of tetracaine or lidocaine anesthesia effect on urethral agita-tion in thoracoscopic male patients during recovery period. Method One hundred and twenty male adults(18 ~60 yr),ASA physical status I and II undergoing elective thoracoscopic surgery ,were randomly divided into three groups of 30 cases in each one. The control group received paraffin oil lubrication catheterization after general anes-thesia induction,whereas the experimental groups received tetracaine gel or lidocaine gel 3~5 g in urethral surface anesthesia before catheterization. Intra-operatively ,urinary catherization was performed with a 16 Fr Foley′s cathe-ter,and a balloon was inflated with 10 mL distilled water. The CRBD was assessed at 0,1,and 12 h after patient′s arrival in the post-anaesthesia care unit. Severity of CRBD was graded as none,mild,moderate and severe. Data were analysed by one-way ANOVA and Fisher′s exact test. P < 0.05 was considered significant. Results Inci-dence and severity of CRBD was reduced in the experimental groups compared with the control group(P < 0.05). Postoperative pain as assessed by visual analogue scale and Richer-SAS was also reduced in the experimental group compared with the control group. Furthermore,in the tetracaine group,catheter-related complaint had less discom-fort than that in the lidocaine group. Conclusion Lidocaine and tetracaine surface anesthesia can significantly reduce catheter-related bladder discomfort after induction ,and tetracaine mucilage lasts for a longer time and less discomfort.
