碧兰麻在儿童正畸病例拔牙术中的麻醉效果观察

目的：应用碧兰麻对儿童正畸的拔牙病例实施局部浸润麻醉下拔牙术,观察其麻醉效果。方法：选取需拔除四颗前磨牙进行正畸治疗的儿童96例,共计384颗牙,分两次拔牙,每次将单颌两侧对称的前磨牙同期拔除。对拔牙术实施的局部麻醉随机分为两组,一侧设计为碧兰麻组48例采用碧兰麻局部浸润麻醉,另一侧设计为利多卡因组48例采用利多卡因局部阻滞麻醉。麻醉起效后开始拔牙,观察记录麻醉时间、麻醉效果,并进行对比分析。结果：碧兰麻组的麻醉起效时间短于利多卡因组（P〈0.01）,而麻醉持续时间长于利多卡因组（P〈0.01）;碧兰麻组的麻醉完全率高于利多卡因组（P〈0.01）。结论：碧兰麻在儿童拔牙正畸病例拔牙术中的麻醉起效快,作用时间长、镇痛效果好、副作用少、安全可靠,可作为儿童拔牙时局部麻醉药物的首选。

The Observation of Anaesthesia Effect of Primacaine on Tooth Extraction in Children Orthodontics

Objeetlve： To explore the application and the anaesthetic effect of primacaine on tooth extraction in children orthodontics.Method： 96 malocclusion children who were designed to pull out four premolar teeth were selected.A total of 384 teeth, the four teeth were extracted in twice and the same name of one side were pulled out in the same term.The patients were divided into two group randomly ： 48 cases of primacaine group were infiltration anaesthetized with prim~aine.48 cases of the lidocaine group were block anesthetized with Lidocaine.Extracted the tooth after anesthesia.The duration of anesthesia and the anesthetic effect were. observed and recorded.Tben compared and analyzed.Result： The onset time of the primaine group was shorter than the lidocaine group （ P〈0.01 ） .The duration of anesthesia of the primacaine group was longer than the lidocaine group （ P〈0.O1 ） .The holonarcosis rate of the primacaine group was hisher than that of the lidocaine group （ P〈0.05 ） .Conclusion： Primacaine used in child~n orthodontic extraction was short onset time, long duration, good analgesic effects and less shoud be the first choice of local anesthetic in children orthodontic of tooth extraction.
