Survey of cardiovascular comorbidities and complications during dental treatment in older patients under monitored anesthesia care

Abstract

Abstract: Older people often have some systemic comorbidities. monitored anesthesia care（ MAC） during dental treatment is very important for older patients with systemic diseases. This study aimed to understand preoperative cardiovascular comorbidity and intraoperative cardiovascular complications in older patients scheduled dental treatment, who underwent MAC by the board certified dental anesthesiology specialist. We conducted a retrospective survey based on anesthetic records in the older patients who underwent MAC from 2015 through 2017 at the department of dental anesthesiology in our hospital. The average number of diseases suffered by those aged ≥ 65 was 2.9. Cardiovascular comorbidities were the most common occurrence in patients aged ≥ 65 years（ n = 614） and the most frequently occurring disease was hypertension. 1.8%（ n=11） of patients aged ≥ 65 postponed their dental treatment because of cardiovascular complications. The incidence of intraoperative cardiovascular complications was 0.3%（ n=2）: one case of the patient aged 65-74 with arrhythmia and another case of the patient aged ≥ 75 with marked hypotension. It was suggested that our attention should be paid to incidence of intraoperative cardiovascular complications during dental treatment in the older patients with cardiovascular comorbidities.
