老年冠心病患者牙根管治疗操作时长的安全性探讨

Investigating safety of treating hours of root canal therapy in the elderly patients with coronary heart disease

目的:探讨老年冠心病患者根管治疗过程中操作时长对老年人安全性的影响。方法:选取需做牙齿根管治疗的老年患者,56例伴有冠心病(试验组)和50例无心血管病史(对照组)。在治疗全过程中,我们进行血压、心率、心电图的监测观察。结果:在治疗过程中,试验组和对照组血压和心率均呈上升趋势,与术前相比,治疗中30min,45min和60min两组老年患者的心率变化皆有显著性改变,治疗后心率恢复正常;在治疗中30min至45min两组病人血压有更显著性差别;但是,治疗后与术前相比血压变化不显著。老年冠心病患者术中更多出现心电图改变。结论:患有冠心病的老年人根管治疗是可行的,但是时间控制在30min,不能超过45min。

Objective： To study the safety of treating hours of root canal therapy in the elderly patients with coronary heart disease. Method： The elderly patients with tooth root canal therapy were selected. 56 patients with coronary heart disease（experimental group） and 50 patients without coronary heart disease（control group） Throughout the course of treatment, we monitored the blood pressure, heart rate and ECG. Result： Blood pressure and heart rate were increased during root canal therapy in patients and control group with statistically significant differences compared with that before operation, while,there was a more than significant difference in blood pressure during 30 min to 45 min of treatment for patients and control group. Electrocardiogram＇s change showed in some with coronary heart disease. Conclusions： Root canal therapy is safe for the elderly with coronary heart disease, but we recommend treating hours of root canal therapy in 30 min and no more than 45 min.
