The influence of oral health status, the number of teeth extracted, and the anesthetic modality used is currently a matter of debate in the prevalence of bacteremia following dental extractions (BDE). The aim of the present study was to analyze the factors affecting the prevalence, duration, and etiology of BDE.
Blood samples were collected from 210 patients at baseline, 30 seconds, 15 minutes, and 1 hour after performing dental extractions. Samples were processed in the Bactec 9240 and the subculture and further identification of the isolates were performed using conventional microbiological techniques.
The prevalence of BDE at 30 seconds, 15 minutes, and 1 hour were 71%, 45%, and 12%, respectively. In the multivariate analysis, the "anesthetic modality" (local anesthesia versus general anesthesia) was the only variable related to BDE.
General anesthesia represents a risk factor for BDE, increasing its prevalence and duration.
口腔健康状况、拔牙数量以及所采用的麻醉方式对拔牙后菌血症（BDE）发生率的影响目前存在争议。本研究旨在分析影响BDE发生率、持续时间及病因的因素。
在拔牙前、拔牙后30秒、15分钟和1小时采集210例患者的血样。样本在Bactec 9240中进行处理，并使用传统微生物技术进行亚培养及分离株的进一步鉴定。
拔牙后30秒、15分钟和1小时的BDE发生率分别为71%、45%和12%。多因素分析显示，“麻醉方式”（局部麻醉与全身麻醉）是与BDE相关的唯一变量。
全身麻醉是BDE的一个危险因素，会增加其发生率和持续时间。
