目的 探讨罗哌卡因与利多卡因在下颌磨牙牙髓炎中的阻滞麻醉效果. 方法 随机选择自2013年6月—2014年12月于该院口腔科就诊的80例下颌磨牙牙髓炎患者作为研究对象,随机分为观察组和对照组,每组40例. 观察组采用罗哌卡因麻醉,对照组使用利多卡因麻醉,观察两组患者麻醉效果. 结果 观察组40例患者38例麻醉成功,手术顺利进行,成功率为95.00%;对照组40例患者32例麻醉成功,成功率为80.00%.观察组麻醉效果明显优于对照组(P>0.05);观察组麻醉起效时间和麻醉持续时间均长于对照组,差异有统计学意义(P<0.05).结论 下颌磨牙牙髓炎治疗中罗哌卡因麻醉成功率高,麻醉持续时间长,能够有效缓解患者术后疼痛.%Objective To study the block anesthesia effect of ropivacaine and lidocaine in mandibular molar pulpitis. Methods 80 cases of patients with mandibular molar pulpitis treated in the department of stomatology from June 2013 to December 2014 were selected as the research object and randomly divided into two groups with 40 cases in each, the ob-servation group were anaesthetized with ropivacaine, the control group were anaesthetized with lidocaine, the anesthesia ef-fects of the two groups were observed. Results 38 cases were anaesthetized successfully of the 40 cases in the observation group, the operation was smooth and the success rate was 95.00%;32 cases were anaesthetized successfully of the 40 cases in the control group and the success rate was 80.00%, the anesthesia effect in the observation group was obviously better than that in the control group, (P>0.05); the onset time of anesthesia and the duration time of analgesia were longer than those in the control group, and the differences were statistically significant (P<0.05). Conclusion Ropivacaine anesthesia in treatment of mandibular molar pulpitis has a higher anesthetic success rate and long duration time of analgesia, which can effectively relieve the patient's pain after operation.
