目的

研究放射性颌骨坏死(ORN)局部病灶的细菌类型及药物敏感性,为临床合理使用抗菌药物提供客观依据。

方法

收集2012年11月5日至2015年9月10日于中山大学附属口腔医院口腔颌面外科就诊的ORN患者局部病灶渗出液标本共106份,送检进行细菌培养和抗菌药物敏感性试验,分析检出菌群的类型和药敏试验结果。

结果

106份送检标本中31份(29.2%)无细菌生长,75份(70.8%)分离培养出细菌。培养出细菌的标本中,双重和多重感染14份(13.2%),单菌种感染61份(57.5%);所有有菌标本共分离出病原菌36种(95株),其中需氧菌25种(78株)、厌氧菌11种(17株),分别占比69.4%和30.6%。药敏试验发现,细菌对利奈唑胺、万古霉素、亚胺培南、美罗培南、阿米卡星、哌拉西林+他唑巴坦最敏感。对红霉素、克林霉素、氨苄西林、头孢唑林、阿奇霉素、克拉霉素等耐药比例较高。

结论

ORN局部病灶细菌谱分布广泛,呈现出菌群多样性,且部分患者为无菌性坏死,因此临床上有必要根据细菌培养和药敏试验结果指导用药,避免抗菌药物的盲目使用。

Objective

To investigate the distribution of bacteria types and antimicrobial susceptibility patterns in osteoradionecrosis of the jaw patients.

Methods

Retrospective analysis of 106 samples of secreta collected from osteoradionecrosis (ORN) patients whom were admitted in the department of oral and maxillofacial surgery, hospital of stomatology, Sun Yat-sen University. These samples were detected by bacterial cultivation and antimicrobial susceptibility test.

Results

There was no existence of bacteria in 31 of 106 samples (29.2%) and bacteria could be cultured in the other 75 samples (70.8%) . Totally 14 of the samples (13.2%) were double or multiple infections, and 61 of the samples (57.5%) were single infection. 36 different kinds of pathogenic bacteria with 95 strains were isolated, including 25 kinds of aerobe (78 strains of 95, 69.4%) and 11 anaerobic bacteria (17 strains of 95, 30.6%) . Bacteria were more sensitive for linezolid, vancomycin, imipenem, meropenem, amikacin, piperacilin and tazobactam in antimicrobial susceptibility. And it also had a higher proportion of antibiotic resistance for erythrocin, clindamycin, ampicillin, cafazolin, azithromycin, clarithromycin.

Conclusions

The diversity and wide range of bacteria were found in patients with ORN, but some patients with aseptic necrosis were also appeared. The results of bacterial cultivation and antimicrobial susceptibility test could guide the drug use to avoid blindly use of antimicrobial drugs.
