老年心血管病患者监护拔牙心肌耗氧量及舒张压的监测结果分析

The analysis on myocardial oxygen consumption and diastolic blood pressure in tooth extraction under electrocardiographic monitoring for elderly patients with cardiovascular diseases

目的:对老年心血管病患者在口腔科拔牙过程中心肌耗氧量及舒张压的监测结果进行分析研究。方法:监测257例患有心血管疾病的老年患者在门诊拔牙过程中心率(HR)、血压(BP)的变化,将能间接反应心肌耗氧量的心率动脉收缩压乘积(Cardiacrate-pressure product RPP)及舒张压在术前、麻药注射中、麻药注射后、拔牙术中、拔牙术后的结果进行统计,分析两者在拔牙各阶段的变化。结果:心肌耗氧量及舒张压在拔牙过程的不同阶段有显著差异。结论:在老年心血管病患者拔牙全程监测心率血压变化,采取各种手段控制血压及心肌耗氧量能有效降低拔牙手术风险。

Objective： To analyze myocardial oxygen consumption（MOC） and diastolic blood pressure（DBP） of elderly patients with cardiovascular disease in tooth extraction.Methods： The changes about heart rate（HR） and blood pressure（BP） of 257 elderly patients with cardiovascular disease were monitored,and studied both Cardiacrate-pressure product（RPP,HR multiplied by SBP） which can react MOC indirectly and DBP in different stages including before extraction,during injection,after injection,during extraction and after extraction.Results： The results indicated that MOC and DBP in different stages of tooth extraction process showed significant differences.Conclusion： It would efficiently decrease surgical risk when we monitor the changes about HR and BP of elderly patients with cardiovascular disease during the whole process of tooth extraction and adopt various steps to control BP and MOC.
