甲哌卡因与利多卡因在儿童牙髓病治疗中的麻醉效果比较

目的比较甲哌卡因与利多卡因在儿童牙髓病治疗中的临床麻醉效果。方法将50例牙髓病儿童患者采用随机数字法分成两组，每组25例，分别应用甲哌卡因和利多卡因局部浸润麻醉，记录两组的麻醉显效时间、术中麻醉效果及不良反应发生情况。结果甲哌卡因和利多卡因在麻醉显效时间上差异无统计学意义（P〉O．05）。而手术操作中，甲哌卡因的麻醉效果优于利多卡因，差异有统计学意义（P〈O．05）。结论甲哌卡因用于儿童牙髓病治疗中的麻醉效果确切，优于利多卡，且不良反应轻，可在临床应用中作为优选麻醉药物。

Comparison of anesthetic efficacy of mepivacaine and lidocaine for treatment of pulpitis in children

Objective To compare local anesthesia effects of mepivacaine and lidocaine for treatment of pulpitis in children. Methods 50 patients were randomly divided into two groups. Group A （25 cases） was treated with local infil- tration with mepivacaine. Group B （25 cases）was treated with local infiltration with lidocaine. The anesthetic effective time, analgesia effects and the adverse reactions were observed during the therapy. Results Anesthetic effective time had no statistical difference between the two groups. However, the analgesia effect of mepivacaine was superior to lidocaine＇ s effect. The comparison of the two groups had statistical difference in operation. Conclusion Mepivacaine is effective and safe for children in louloitis therapy.
