目的:通过临床观察和比较,评价阿替卡因肾上腺素注射液(必兰)的临床应用效果。方法:将790例病例共1 098颗牙分为实验组和对照组,分别使用必兰和利多卡因麻醉,进行牙髓治疗、活髓基牙预备和拔牙。采用视觉模拟量表(VAS)和语言评价量表(VRS),评价两者注射时患者的疼痛程度和镇痛效果,并记录产生的不良反应。结果:与对照组相比,实验组患者浸润麻醉和阻滞麻醉时的注射疼痛程度均显著降低(P<0.01);且无论牙髓治疗、活髓基牙预备或拔牙,必兰的镇痛效果也更好。两组均无严重不良反应发生。结论:使用必兰局部麻醉时,无明显注射时疼痛、镇痛效果显著、麻醉时间保证、手术视野清晰、不良反应少,是一种安全可靠、可在临床普遍推广使用的口腔局部麻醉药。
Objective: To evaluate the clinical effect of articaine epinephrine injection (Bilan) through clinical observation and comparison. Methods: A total of 1 098 teeth from 790 cases were divided into experimental group and control group. The patients were treated with bilanol and lidocaine anesthesia, endodontic treatment, live pulp preparation and tooth extraction. The visual analog scale (VAS) and verbal evaluation scale (VRS) were used to evaluate the pain level and analgesic effect of the two patients on the injection and record the adverse reactions. Results: Compared with the control group, the patients in the experimental group were significantly less painful in infiltration anesthesia and block anesthesia (P <0.01). And no difference was found in dental pulp treatment, live pulp abutment preparation or tooth extraction, The effect is better. No serious adverse reactions occurred in both groups. Conclusion: When using Bilan local anesthesia, there is no significant pain when injection, analgesic effect is significant, anesthesia time assurance, clear operative field of view, less adverse reactions, is a safe and reliable, and can be widely used in clinical oral local anesthetic.
