目的:通过体感诱发电位检查的方法探讨复方利多卡因乳膏对阴茎背神经敏感性的影响.方法:对34例早泄患者局部使用复方利多卡因乳膏前后分别行阴茎背神经躯体感觉诱发电位(DNSEP)和阴茎头躯体感觉诱发电位(GPSEP)检查,记录所有受试者DNSEP和GPSEP的潜伏期及波幅变化.结果:局部使用复方利多卡因乳膏之后,DNSEP和GPSEP的潜伏期都得到明显延长(P＜0.001,P＜ 0.001),且两者的波幅都得到降低(P＜0.001,P＜0.001).结论:复方利多卡因乳膏可通过降低阴茎背神经敏感性来达到延长射精潜伏期的作用,我们认为通过DNSEP和GPSEP的检查,筛选出阴茎背神经敏感性高的患者,选择性使用局部麻醉药物治疗,可以得到更好的治疗效果.
