亚甲蓝联合罗哌卡因对肛肠病术后镇痛的疗效观察

Clinical Observation on Methylene Blue Combined with Ropivacaine for Postoperative Analgesia in Anorectal Disease Patients

为观察亚甲蓝联合罗哌卡因注射对肛肠痫术后镇痛的临床疗效，将380例痔、肌瘘、肛裂患者随机分为治疗组和对照组，每组190例。治疗组术后采用亚甲蓝联合岁哌卡因行创缘多点注射，对照组术后给予常规包扎创口，必要时给予常规镇痛；两组分别于术后2d对镇痛效果进行对比观察。结果显示，治疗组术后疼痛和尿潴留的发生率显著低于对照组（P〈0．01），而创面愈合时间两组差异无统计学意义（P〉0．05）。结果表明，亚甲蓝联合罗哌卡因注射治疗肛肠病术后疼痛效果显著。

To observe the clinical efficacy of methylene blue combined with ropivacaine for postoperative analgesia in anorectal diseases patients,380 cases with hemorrhoids,anal fistula and fissure were randomly divided into treament group and control group, 190 cases for each. The treatment group received multi point injection of methylene blue and ropivacaine at the wound margins,while the controls routine dressing changes with conventional analgesia if necessary. Both groups were compared about postoperative analgesia on the 2nd day after surgery. The results showed that the incidence of postoperative pain and urinary retention was significantly lower in the treatment group than that in control group（ P 〈0.01）,while there was no significant difference between the two groups in wound healing time（ P〉0.05）. It is concluded that methylene blue combined with ropivacaine is effective for postoperative analgesia in anorectal diseases patients.
