目的研究心理指导和术前牙科知识讲解对患有牙科焦虑症的心血管疾病患者在拔牙过程中心率、血压的变化。对牙科焦虑症患者心电监护术中的作用进行评价。方法对心血管疾病患者采用改良的牙科焦虑量表筛选出具有明显焦虑症状患者80例,在心电监护下拔牙,观察两组患者在拔牙前、麻醉后、拔牙中以及拔牙后10min的心率和血压的变化。干预组对患者进行必要和有效的心理指导和拔牙知识讲解。结果两组患者拔牙麻醉过程中和拔牙后血压及心率均有升高,其中干预组各项指标升高幅度较低,而对照组拔牙时心率和收缩压术中明显升高(P<0.05)。结论在拔牙前对牙科焦虑症及患有心血管疾病的患者进行有效的心理指导和必要的口腔知识的讲解可以降低此类患者由于焦虑所带来的血压和心率的大幅度变化,保证患者的安全。
Objective To study the changes of heart rate and blood pressure during tooth extraction in patients with cardiovascular diseases with dental anxiety based on psychological guidance and preoperative dental knowledge. Dental anxiety patients with ECG monitoring of the role of evaluation. Methods Eighty patients with obvious anxiety symptoms were selected by modified dental anxiety scale in patients with cardiovascular diseases. Tooth extraction was performed under ECG. The heart rate and blood pressure before and after tooth extraction, anesthesia, tooth extraction and 10 minutes after tooth extraction were observed. The change. Intervention group of patients necessary and effective psychological guidance and tooth extraction knowledge. Results The blood pressure and heart rate increased during the period of tooth extraction and tooth extraction in both groups. The increase rate of each index in the intervention group was lower than that in the control group (P <0.05) . Conclusions Effective dental counseling and the necessary oral knowledge of patients with dental anxiety and cardiovascular disease prior to tooth extraction can reduce the patient’s safety due to the dramatic changes in blood pressure and heart rate associated with anxiety .
