拔牙术是口腔外科门诊常见的手术之一,拔牙过程中由于患者特别是老年患者的心理变化,常会出现一些应激反应如:心率、血压的升高,从而增加心血管病发病的风险。为增强手术的安全性,减少心血管病的发病,我们从2005年5月至2006年10月,对121例老年拔牙患者进行了心理干预的对比观察 Tooth extraction is one of the common surgical procedures in dental surgery. During the tooth extraction, some stress reactions such as heart rate and blood pressure often occur due to psychological changes in patients, especially in elderly patients, thus increasing the risk of cardiovascular disease.
