盐酸依替卡因在口腔外科手术中的应用：一项临床研究。

J Oral Surg. 1978 Nov;36(11):863-5.

Etidocaine hydrochloride had a rapid onset time, high frequency of surgical anesthesia, long duration and no side effects in 25 healthy patients who had 50 impacted third molars removed. Etidocaine compared favorably to lidocaine and its duration of action was two times longer.

在25例拔除50颗阻生第三磨牙的健康患者中，盐酸依替卡因起效迅速、手术麻醉频率高、持续时间长且无副作用。依替卡因与利多卡因相比效果良好，其作用持续时间是利多卡因的两倍。
