A study of the anesthetic efficacy of a eutetic mixture of local anesthetics (EMLA cream) versus lidocaine infiltration in extracorporeal shock wave lithotripsy (ESWL) was done. A total of 46 patients had 30 gm. of EMLA cream applied to the skin over the kidney and 45 had subcutaneous infiltration anesthesia with 20 ml. 1% lidocaine with epinephrine. All patients received an intravenous dose of morphine just before ESWL. The patients were comparable with regard to age, sex, weight, morphine dosage, number of shock waves given and duration of treatment. Median pain score and the amount of supplementary analgesics were not significantly different between the 2 groups. There were no significant differences between the groups with regard to post-ESWL skin changes. Therefore, EMLA cream can be recommended for ESWL provided it is applied correctly.
进行了一项关于局部麻醉药的共熔混合物（EMLA乳膏）与利多卡因浸润麻醉在体外冲击波碎石术（ESWL）中的麻醉效果的研究。总共46例患者在肾脏上方皮肤涂抹30克EMLA乳膏，45例患者接受20毫升含肾上腺素的1%利多卡因皮下浸润麻醉。所有患者在ESWL治疗前均静脉注射一剂吗啡。患者在年龄、性别、体重、吗啡剂量、给予的冲击波次数和治疗持续时间方面具有可比性。两组之间的中位疼痛评分和补充镇痛药的用量无显著差异。两组在ESWL后皮肤变化方面无显著差异。因此，如果正确使用，EMLA乳膏可推荐用于ESWL。
