下颌第三磨牙拔除术中不同操作过程对心率影响的临床研究

Influence of Operation Process on Heart Rate during Extraction of Mandibular Third Molar

目的:通过监测下颌第三磨牙拔除术中患者心率变化,评估患者对不同手术操作过程的焦虑强度。方法:60例患者局麻下行下颌阻生第三磨牙拔除术,手术过程中持续监测心率。比较麻醉注射、切开翻瓣、涡轮机使用、锤击、牙挺使用、牙钳使用、缝合操作过程中患者心率变化以评估其焦虑强度。结果:麻醉注射、锤击、牙挺使用、牙钳使用操作过程中心率明显升高,且随着锤击、牙挺使用操作时间延长心率升高更为明显。结论:心率变化显示患者对麻醉注射、锤击、牙挺使用、牙钳使用操作过程焦虑强度较大,且与操作持续时间相关。

Objective： To assess the intensity of anxiety during extraction of mandibular third molar with different operation process by monitoring patients＇ heart rate changes. Methods： The study included 60 patients who were extracted the mandibular third molar under local anesthesia. The heart rate was monitored continuously during treatment to measure the anxiety. Different operation processes, including narcotic injection, flap surgery, turbine using, hammer using, dental elevator using, dental forceps using, and suturing operation. Results： Significant in- crease of heart rate was observed during operation process of narcotic injection, hammer using, dental elevator u- sing, and dental forceps using. It is more significant when the operation time of hammer using and dental elevator using was prolonged. Conclusion： Patients have higher levels of anxiety during the operation process of narcotic in- jection, hammer using, dental elevator using, and dental forceps using, which is positively correlated with the oper- ating time.
