罗哌卡因在肛肠科局麻手术中的应用

为评价罗哌卡因在肛肠科局麻手术中的应用效果，将200例混合痔、肛乳头瘤、肛裂、肛瘘、肛周脓肿手术患者（ASAⅠ～Ⅱ级）分为两组，随机选择使用0．2％罗哌卡因（16±2）ml或者0．5％利多卡因（16土2）ml进行局部麻醉，测量感觉神经阻滞时间、感觉神经恢复时间、手术后镇痛时间。结果显示，两组感觉神经阻滞时间无明显差异，感觉恢复时间，罗哌卡因组优于利多卡因组（P〈0．05）；手术后镇痛时间，罗派卡因较利多卡因有明显延长（P〈0．01）；罗哌卡因5例、利多卡因32例出现轻度不良反应。结果表明，罗哌卡因有局麻镇痛双重效应，具有起效快、麻醉效果好、持续时间长、不良反应少等优点。

Application of Ropivacaine in Local Anesthesia for Operation of Coloproctologic Department

For the objective of assess the efficacy of Ropivacaine used in local anesthesia for operation of anorectal disease, including mixed hemorrhoids, anal fissure, anal fistula, perianal abscess and papillary tumor, the 200 patients to be subjected to opeation（ASA Ⅰ～Ⅱ grade） were random divided into two groups to adopt 0.2% Ropivacaeine of （16±2）ml,or 0.5% lidocaine of （16±2）ml for local anesthesia;then sensory nerve block time, sensory nerve recovery time, postoperative analgesia time were measured. As results,in sensory nerve block time there was not great difference;in sense recovery time Ropivacaine group was superior to Lidocaine group（ P 〈0.05） ;in postoperative analgesia the lasting time of Ropivacaine was distinctly longer than that of Lidocaine（ P 〈0.01）. Mild adverse reaction oceured in 5 cases of Ropivacaine group and in 32 cases of Lidocaine group. Above results show that Ropivacaine has double efficacies of local anesthesia and analgesia, and has such advantages as faster onset time, better anesthesia efficacy, longer lasting time and less adverse reaction, etc.
