目的:研究表象训练对龋齿拔牙患者手术前焦虑及应激状况的影响。方法:97名患者随机分为A、B、C3组,实验过程中,B组患者观看自制龋齿拔牙手术视频,C组患者观看完视频后进行表象训练,A组不进行心理干预。手术前1个小时对患者进行焦虑的测评并抽血检测血浆皮质醇含量,进行数据分析。结果:表象训练组患者在焦虑量表上得分及血浆皮质醇浓度低于视频观看组患者,视频观看组患者在焦虑量表上得分及血浆皮质醇浓度低于对照组,且三者差异具有统计学意义(F=17.48,20.90;P<0.001);3组患者在焦虑量表上得分及血浆皮质醇浓度两两之间差异具有统计学意义(P<0.01)。结论:心理干预可以减少龋齿拔牙患者术前焦虑情绪,降低应激反应,且表象训练的效果要优于视频观看的方式。
OBJECTIVE: To study the effect of imagery training on the anxiety and stress before tooth extraction in dental caries extraction patients. Methods: Ninety-seven patients were randomly divided into A, B, and C3 groups. During the experiment, patients in group B watched video of homemade deciduous dental caries. Patients in group C watched the video and performed image training. Group A received no psychological intervention. One hour before surgery, patients were evaluated for anxiety and blood samples were taken for plasma cortisol level analysis. Results: The scores of anxiety scale and plasma cortisol in the training group were lower than those in the video watching group. The scores of anxiety scale and plasma cortisol in the video watching group were lower than those in the control group, and the differences among the three groups were statistically significant (F = 17.48, 20.90; P <0.001). There was significant difference between the two groups in the anxiety scale score and the plasma cortisol concentration (P <0.01). Conclusion: Psychological intervention can reduce preoperative anxiety and reduce stress response in dental caries extraction, and the effect of image training is better than that of video watching.
