Patients with bacteremia after dental extraction, third-molar surgery, dental scaling, endodontic treatment, and bilateral tonsillectomy were studied by means of lysis-filtration of blood samples with subsequent aerobic and anaerobic incubation. Samples were obtained before, during, and 10 min after treatment. Bacteremia was observed in 100% of patients after dental extraction, 55% of patients after third-molar surgery, 70% of patients after dental scaling, 20% of patients after endodontic treatment, and 55% of patients after bilateral tonsillectomy. Anaerobic microorganisms were isolated more frequently than aerobic microorganisms were, and viridans group streptococci were the most commonly isolated bacteria. Ten minutes after treatment, the frequency as well as the magnitude of bacteremia showed pronounced reduction.
通过对血样进行裂解过滤并随后进行需氧和厌氧培养,对拔牙、第三磨牙手术、洗牙、牙髓治疗及双侧扁桃体切除术后发生菌血症的患者展开了研究。在治疗前、治疗期间及治疗后10分钟采集样本。拔牙后100%的患者出现菌血症,第三磨牙手术后55%的患者出现菌血症,洗牙后70%的患者出现菌血症,牙髓治疗后20%的患者出现菌血症,双侧扁桃体切除术后55%的患者出现菌血症。厌氧微生物的分离频率高于需氧微生物,草绿色链球菌是最常分离出的细菌。治疗10分钟后,菌血症的频率和程度均显著降低。
