Objective:To observe the effect of epidural continuous pumping Lidocaine anesthesia in transurethral resection of the prostate(TURP) in elderly.Method:40 cases of TURP in elderly were chosen and randomly divided into continuous pump injection group(group C) and fractional injection group(group F),20 cases in each group.Group C was given trace injection pump for epidural cavity pump note local anesthetics,group F was given several times to traditional medicine way,determined before anesthesia and epidural drug after 5,10,20,30,60 min each point of the blood pressure,HR,SpO2,at the same time the analgesic effect of time,anesthesia plane,the effects of anesthesia,muscle loose total quality,drug amount were evaluated.Result:BP and HR of group C fluctuation significantly reduced,drug amount decreased,compared with group F,the differences were statistically significant(P<0.05).Anesthetic plane and analgesic effect between two groups and SpO2,the differences had no statistical significance(P>0.05).Conclusion:Epidural micro pump for pumping dosing method used for the elderly through the TURP can give medicine method of discontinuous points times the same anesthesia effect,smooth blood pressure,heart rate,less dose,is a safe drug delivery methods suitable for elderly people’s physiological characteristics.%目的：观察硬膜外持续泵入利多卡因在老年人经尿道前列腺电切术中的麻醉效果。方法：选择经尿道前列腺电切术老年患者40例，按照随机数字表法分为持续泵注组(C组)和分次推注组(F组)，各20例。C组用微量注射泵持续向硬膜外腔泵注局麻药，F组则采用传统分次给药方式，分别测定麻醉前及硬膜外给药后5、10、20、30、60 min各时点的血压和HR、SpO2，同时评定镇痛起效时间、麻醉平面、麻醉效果、肌松质量、用药总量。结果：C组BP、HR波动显著降低，用药总量下降，与F组比较差异均有统计学意义(P<0.05)。两组麻醉阻滞平面、镇痛效果、SpO2比较，差异均无统计学意义(P>0.05)。结论：硬膜外微泵持续泵入给药方法用于老年人经尿道前列腺电切术可以达到间断分次给药法同样的麻醉效果，血压、心率平稳，用药量少，是一种安全的适合老年人生理特点的给药方法。
