Application of oral acetaminophen combined with urethral surface anesthesia in local anesthesia cystoscopy

Objective To investigate the application efficacy of oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy. Methods From January 2016 to June 2017, 180 male patients aged from 60 to 86 years old, whose average age was 71 years old and treated by local anesthesia cystoscopy were collected in this study in the department of Urology of Xuzhou Medical University Affiliated hospital. They were divided into two groups according to the time sequence of visiting doctor. The patients in the research group were treated with oral acetaminophen stapler with compound lidocaine cream and lidocaine injection urethral infusion anesthesia before the examination.The control group was using lidocaine injection urethral infusion anesthesia. To compare the successful rate of operation, operating time and the visual analogue score (VAS) before and after the operation, the patients' limb twist and the tension were observed and recorded. The software of SPSS 16.0 was used for statistical analysis. Results The successful rate of operation in research group and control group was 97.78% and 91.11%. The VAS score before the operation was (3.2±1.8) and (6.8±2.2). The incidence of complications after treatment was 5.55% (5/90) and 27.78% (25/90). The PSS score of 1 h after treatment was (1.1±1.7) and (3.1±1.2). The satisfaction rate was 90.0%(81/90) and 57.8%(52/90). The differences between the two groups were statistically significant(P 0.05). Conclusions Taking oral acetaminophen stapler with compound lidocaine cream combined with lidocaine injection in local anesthesia cystoscopy could obviously reduce urethral pain and the anxiety in the opertion of local anesthesia cystoscopy, which obviously superior to use lidocaine injection urethral infusion anesthesia only. The efficacy and safety were definitely and had got better clinical outcomes. Key words: Acetaminophen; Cystoscopy; Lidocaine; Compound lidocaine cream
