慢性化脓性中耳炎156例脓培养及药敏试验分析

目的：了解慢性化脓性中耳炎病原菌的分布及其对药物的敏感性,以指导临床合理用药。方法：对156例慢性化脓性中耳炎患者的脓培养及药敏试验结果进行分析。结果：156份标本中检出病原菌127株,其中,细菌119株,真菌8株;前4位细菌依次为凝固酶阴性葡萄球菌41株（32.23%）、铜绿假单胞菌19株（15.0%）、金黄色葡萄球菌18株（14.2%）、变形杆菌11例（8.7%）;敏感药物因菌种而异。结论：慢性化脓性中耳炎以凝固酶阴性葡萄球菌、铜绿假单胞菌、金黄色葡萄球菌、变形杆菌为主,临床医生应根据药敏试验结果合理选用抗生素。

The pus cultivation and drug sensitive test analysis of chronic suppurative otitis media in 156 cases

Objective：To investigate the distribution of pathogenic bacteria and its drug sensitivity of chronic suppurative otitis media,and guide clinical rational drug use. Methods：The data of the pus cultivation and drug sensitivity test of chronic suppurative otitis media in 156 patients were retrospectively analyzed. Results：One hundred and twenty-seven strains pathogenic bacteria were detected in156 specimens,which included 119 strains of bacteria and 8 strains of fungi. The four leading bacteria were coagulase negative staphylococcus（41 strains,32. 23%）,pseudomonas aeruginosa（19 strains,15. 0%）,staphylococcus aureus（18 strains,14. 2%） and proteus（ 11 cases,8. 7%）. Different pathogenic bacteria had different drug sensitivities. Conclusions： The coagulase negative staphylococcus,pseudomonas aeruginosa,staphylococcus aureus and proteus are the major pathogenic bacteria in chronic suppurative otitis media. The reasonable choice of antibiotics should base on the drug sensitive test.
