心血管疾病患者拔牙安全性探讨

An Approach to the Safety of Tooth Extraction in Patients of Cardiovascular Disease

本文对492例心血管病患者789例次拔牙,进行了分组可行性研究。分组依据于病情程度。A组者病情较轻,手术安全系数较大。B组者病情较重,术前虽作药物准备,麻醉或拔牙时可出现血压、心律、ST段、T波改变者仍明显高于A组(P<0.01)。C组者病情最重或尚处急性病发作期、恢复期等,属手术禁忌,较易发生手术意外。将需要拔牙的心血管疾病患者分A,B,C三组,根据不同的病情采取不同的监测、治疗手段,对提高拔牙手术安全性具有一定的意义,且具有较大的实用价值。

According to the severity of cardiovascular diseases, 492 cases totaling 789 tooth extractions were classified into 3 groups. The practicability of classif ication was studied. Group A: Symptoms were mild, the safety coefficient of operation was relatively high. Group B: Symptoms were more severe. Although the patients had been given medicine before operation, changes in blood pressure, heart rhythm, ST-T segment were still more frequent than in group A (P<0.001). Group C: Symtoms were most severe, and/or the patients were still in acute stage or convalescence and were contraindicated for operation. Accidents occurred much more frequently during operation.The result indicated that the classification hed practical value in that different kinds of monitoring and treatment could be given and the safety of tooth extraction in patients with cardiovascular diseases could be improved.
