目的探讨必兰局部浸润麻醉与利多卡因下牙槽神经阻滞麻醉治疗下颌磨牙急性牙髓炎的镇痛效果。方法将94例下颌磨牙急性牙髓炎患者随机分为两组,实验组采用必兰局部浸润麻醉,对照组采用利多卡因下牙槽神经阻滞麻醉。麻醉5-10min后,施行开髓及牙髓摘除术,记录并统计医生和患者综合评价麻醉效果。结果两组开髓和拔髓的麻醉效果均无统计学差异(P>0.05)。结论必兰局部浸润麻醉在下颌磨牙急性牙髓炎的治疗过程中,可以取得与利多卡因下牙槽神经阻滞麻醉相近的麻醉成功率;考虑到患者感受和麻醉并发症,可首选必兰局部浸润麻醉。
Objective To investigate the analgesic effect of local infiltration anesthesia with biladal anesthesia and lower alveolar nerve block with lidocaine for acute pulpitis of mandibular molar. Methods A total of 94 patients with acute pulpitis of mandibular molars were randomly divided into two groups. The experimental group was treated with Bilan local infiltration anesthesia, and the control group received lidocaine lower alveolar nerve block anesthesia. 5-10min after anesthesia, the implementation of open pulp and pulp removal, recording and statistics of doctors and patients a comprehensive evaluation of anesthesia. Results There was no significant difference in the anesthetic effect between the two groups (P> 0.05). Conclusion Bilan local infiltration anesthesia in the treatment of acute pulpitis of mandibular molar can achieve similar success rate of anesthesia with the lower alveolar nerve block anesthesia of lidocaine. Considering the patients’ feelings and complications of anesthesia, Bilan Local infiltration anesthesia.
