盐酸甲哌卡因在儿童乳牙拔除中的麻醉效果观察

Anesthesia Effects of Mepivacaine Hydrochloride on Children's Deciduous Teeth Extraction

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 investigate the anesthesia effects of mepivacaine hydrochloride on children＇s deciduous teeth extraction.Methods： A total of 451 children were diagnosed as retainted deciduous teeth,and randomly divided into experimental group（ n = 226）and control group（ n = 225）. In the experimental group,children were injected with mepivacaine hydrochloride,and in the control group children were injected with lidocaine. After injected 2 min,5 min and 10 min,children were taken in pain tests,the pain degree during the injection and the anesthesia effects during extraction were recorded. Results： The onset time of anesthesia was shorter in experimental group than control group（ P0.05）. The pain of injection was mild in experimental group than control group（ P 0.05）. The effective rate was 96.90% in experimental group and 87.55% in control group,there was statistically difference between two groups（ P 0.05）.Conclusion： Mepivacaine hydrochloride can shorten the onset time of anesthesia,reduce the pain of injection. The anesthesia effects of mepivacaine hydrochloride on children＇s deciduous teeth extraction are good.
