研究放疗对口咽部菌群的影响有助于控制术前放疗患者的术后感染,对80例患者做放疗前及放疗结束后的口咽拭子细菌检查,其中后40例还做了放疗两周后的致病菌分离培养和药物敏感试验。30例正常人做为对照。结果显示放疗后口咽部的凝固酶阳性金黄色葡萄球菌、β-溶血性链球菌、白色念珠菌、变形杆菌、绿脓杆菌明显增加。药敏试验表明,所有致病菌均对氧哌嗪青霉素敏感,其次是丁胺卡那霉
To study the effect of radiotherapy on oropharyngeal flora can help control the postoperative infection in patients undergoing preoperative radiotherapy. 80 cases of patients undergoing radiological examination before or after radiotherapy and oropharyngeal swabs after the end of radiotherapy, among which 40 cases have also done radiotherapy two After weeks of pathogen isolation and culture and drug sensitivity test. 30 normal people served as controls. The results showed that coagulase-positive Staphylococcus aureus, β-hemolytic streptococcus, Candida albicans, Proteus, and Pseudomonas aeruginosa increased significantly after radiotherapy. Drug susceptibility testing showed that all pathogenic bacteria are sensitive to Oxopiprazin penicillin, followed by Kanamycin amidocin
