【摘要】目的?探讨利多卡因凝胶在男性患者膀胱灌注化疗中的效果。方法?80例膀胱癌术后灌注化疗患者为对象，随机分为两组，实验组（利多卡因凝胶组）在灌注导尿前进行利多卡因凝胶尿道润滑、表面麻醉，对照组（常规组）则按常规使用石蜡油润滑导尿法灌注。结果?实验组在一次性置管成功率、疼痛程度、化疗药液保留时间等方面明显优于对照组组，有差异性（p＜0.05）。结论?采用利多卡因凝胶进行尿道润滑、局部麻醉，有显著的镇痛和润滑效果，可减轻患者痛苦，提高插管成功率和延长灌注药物保留时间，是提高疗效及灌注依从性的有效措施之一。

【Abstract】[英文摘要部分句子需修改,一般objective,methods,results里面用一般过去时态。可参考我刊网刊文章进行修改] Objective To discuss the efficiency of lidocaine gel in male patients with bladder irrigation chemotherapy. Methods. A total of eighty patients with bladder cancer were randomly divided into two groups, who received the treatment of bladder irrigation chemotherapy after operation. The patients in experimental group were infused lidocaine hydrochloride gel into urethra for mucosa surface anesthesia and lubrication before insertting catheter,while the patients in control group were treated with insertting catheter after using liquid lubrication oil. Results The one-time success rate of insertting catheter, the degree of pain, the chemotherapy liquid retention time in the experimental group were significantly better than those in the control group. There were statistical significance between the two groups (P<0.05). Conclusions Lidocaine gel could alleviate the suffering of patients, improve the one-time success rate of insertting catheter and prolong the retention time of the drug infusion for significant analgesic and lubrication effect. Lidocaine gel application in male patients with bladder irrigation chemotherapy was one of the effective measures to improve curative efficacy and irrigation compliance.
