目的:观察盐酸甲哌卡因在儿童乳牙拔除中的麻醉效果。方法:将451例临床诊断为乳牙滞留,需要拔除乳牙的患儿随机分为试验组226例和对照组225例,试验组和对照组分别采用盐酸甲哌卡因和2%盐酸利多卡因局部浸润麻醉,对两组患儿分别在注射后2 min、5 min和10 min时用探针在牙周进行疼痛测试的反应、麻醉注射过程中的疼痛评分以及拔牙过程中麻醉效果进行评价。结果:盐酸甲哌卡因与利多卡因相比,麻醉起效时间短,麻醉注射过程中疼痛轻,差异有统计学意义(P<0.05)。盐酸甲哌卡因麻醉总有效率为96.90%,高于利多卡因麻醉总有效率(87.55%),差异有统计学意义(P<0.05)。结论:盐酸甲哌卡因应用于儿童乳牙拔除中的局部浸润麻醉,起效时间快、注射过程中疼痛小,麻醉效果较好,值得临床推广。
Objective: To observe the anesthetic effect of mepivacaine hydrochloride in the removal of deciduous teeth in children. Methods: A total of 451 children with deciduous teeth who were diagnosed as deciduous teeth were randomly divided into experimental group (226 cases) and control group (225 cases). The experimental group and the control group were treated with mepivacaine hydrochloride and lidocaine hydrochloride 2% Infiltration anesthesia, the two groups of children at 2 min, 5 min and 10 min after injection with the probe in the periodontal pain test response, anesthesia during injection pain rating and extraction during anesthesia evaluation. Results: Compared with lidocaine, mepivacaine hydrochloride had shorter onset of anesthesia and less pain during anesthesia injection, the difference was statistically significant (P <0.05). The total effective rate of mepivacaine hydrochloride was 96.90%, higher than the total effective rate of lidocaine anesthesia (87.55%), the difference was statistically significant (P <0.05). CONCLUSION: Mepivacaine hydrochloride is suitable for local infiltration anesthesia in children with deciduous teeth, its onset time is quick, its pain during injection is small and its anesthetic effect is good, which is worthy of clinical promotion.
