罗哌卡因联合亚甲蓝用于肛门疾病术后镇痛效果观察

Observation on the Postoperative Analgesic Efficacy of Ropivacaine Mixed with Methylene Blue after the Operations for Anal Disease

为探讨罗哌卡因联合亚甲蓝用于肛门疾病术后镇痛的效果，对200例肛门疾病术后患者应用罗哌卡因、注射用水和亚甲蓝的混合液（1：1：0．2）行创面浸润神经阻滞麻醉（治疗组），80例肛门疾病术后患者给予常规止痛（对照组），对比观察两组镇痛效果。结果显示，治疗组Ⅰ度止痛有效率为75．0％，对照组为25．0％，差异有统计学意义，P〈0．05。结果表明，罗哌卡因联合亚甲蓝用于肛门疾病术后镇痛效果显著。

The objective of the study was to assess the postoperative analgesic efficacy of Ropivacaine mixed with Methylene blue（in injection water） after the operations for anal disease. Two hundreds patients, who had undergone anal disease operations, received nerve block anesthesia by wound infiltration of Ropivacaine,injection water and Methylene blue mixture（1 ： 1 ： 0.2）（the study group）,while 80 patients received routine analgesia management（the control group）. Results showed that the effectiveness rate of analgesia grade I was 75.0% in the study group vs 25.0% in the control group（ P 〈0.05）. It is concluded that the combined method is of notable postoperation analgesic efficacy.
