Abstract:
Objective: To explore the application effect of light sedation technique in impacted tooth extraction in patients with anxiety. Methods: Intravenous infusion of propofol was administered to 20 patients with mandibular impacted teeth anxiety, and the impacted teeth were removed when the bispectral index (BIS) reached 80-85. The patients' heart rate (HR), mean arterial pressure (MAP), respiratory rate and blood oxygen saturation were monitored during operation, and the patients were instructed to record the visual analogue scale (VAS) after operation, and were asked about anterograde amnesia. SPSS 20.0 software package was used for data statistics, paired t test was used to compare the differences between intraoperative physiological indexes and the time of admission, and descriptive analysis was used to analyze the intraoperative pain of the patients. Results: All patients successfully completed the operation, and there were no obvious adverse reactions during the operation.There were no abnormalities in HR, MAP, respiratory rate and blood oxygen saturation. The postoperative VAS scores of the patients were 1-3, and the patients' anterograde amnesia of the start of surgery, mucosal incision and dental drill sound were recorded, which means that the anxiety was relieved. Conclusion: For the removal of mandibular impacted teeth in patients with dental anxiety, propofol intravenous light sedation technology (BIS=80-85) can achieve satisfactory results, reduce patients' anxiety and improve comfort.

摘要：
目的： 探讨浅镇静技术在焦虑患者阻生牙拔除术中的应用。方法： 对20例下颌阻生牙焦虑患者行丙泊酚静脉输入，在患者脑电双频指数（bispectral index，BIS)达到80~85时拔除阻生牙，术中监测患者心率(heart rate，HR)、平均动脉压（mean arterial pressure，MAP）、呼吸频率及血氧饱和度等，术后指导患者记录视觉模拟评分法（visual analogue scale，VAS）评分及询问患者顺行遗忘情况，采用SPSS 20.0软件包对数据进行数据统计，配对t检验比较术中生理指标与入室时的差异性，采用描述性分析法分析患者术中疼痛情况。结果：所有患者均顺利完成手术，未出现明显不良反应，术中HR、MAP、呼吸频率及血氧饱和度均未出现异常，患者术后VAS评分为1~3分，对手术开始、黏膜切开及牙钻声音顺行遗忘，即焦虑得到缓解。结论： 针对牙科焦虑症患者下颌阻生牙的拔除，丙泊酚静脉浅镇静技术（BIS=80~85）即可达到较为满意的效果，减轻患者焦虑，提高舒适度。
