摘　　要：目的:观察用笑气吸入镇静技术,辅助拔除下颌阻生智齿对减轻牙科焦虑症的临床效果。方法:收集2012-01—2013-06在我科行下颌阻生智齿拔除术的患者共70例,随机分为笑气吸入组(A组)30例,对照组(B组)40例。A组局部麻醉的同时,使用笑气吸入辅助镇静技术;B组仅使用局部麻醉药。对比观察手术前、中、后的血压、心率、呼吸、焦虑程度、疼痛评分、拔牙时间等,并对结果进行统计分析。结果:2组患者手术前后心率和血压变化、牙科焦虑评分、局麻时VAS疼痛评分、术后健忘情况以及拔牙时间等差异均有显著性(P<0.05)。结论:笑气吸入清醒镇静技术具有良好的抗焦虑、止痛、遗忘作用,能够有效降低下颌阻生智齿拔除的紧张、恐惧等焦虑情绪,并能缩短时间。AIM ： To evaluate the clinical effects of nitrous oxide inhalation on dental anxiety during extraction of impacted mandibular wisdom teeth. METHODS ： 70 patients with impacted mandibular wisdom tooth extraction were included in this study. The patients were divided into the nitrous-oxide inhalation group （ n = 30） and local anesthesia group （ n = 40）. Blood pressure, heart rate, breathing and variation of calm situation, degree of anxiety, pain score were recorded before, during and after tooth extraction. The parameters were statistically analysed by t - test. RESULTS： All teeth were successfully extracted and with no serious complications. Nitrous oxide inhalation group showed much less changes in heart rate and blood pressure; much lower dental anxiety score, VAS pain score and post- operative forgetfulness than local anesthesia group （ P 〈 0.05 ）. CONCLUSION ： Nitrous oxide inhalation is effective in alleviating dental anxiety during impacted wisdom tooth extraction.
