摘要
目的了解创伤门诊常见伤口细菌分布特点,为伤口感染控制提供参考。方法采用伤口标本采集和细菌分离培养方法,对患者伤口不同阶段细菌分布情况进行了检测。结果从抗菌药物应用前的165例病人伤口标本中检出细菌141株,涉及患者129例,细菌培养阳性率为78.2%。所检出的141株细菌中,革兰阴性菌占主导地位,构成比达到63.12%。病人使用抗菌药物1周后,伤口细菌检出率明显下降,检出阳性率由使用前的78.2%下降到38.2%;停用抗菌药物15 d后,伤口细菌检出率又有回升,阳性率由抗菌药物使用中的38.2%回升到69.2%。伤口分离的细菌对临床常用抗菌药物普遍耐药。结论慢性伤口感染菌以革兰阴性菌为主,对抗菌药物普遍耐药。
Objective To understand distribution features of bacteria in common outpatients′ wound and to provide reference for infection control.Methods Wound specimen collection and bacteria isolation and culture were used to detect bacteria distribution in different phases of outpatients′ wound.Results 141 strains bacteria from 165 cases of chronic outpatients′ wound were detected before the use of antibiotics and 129 patients were involved.The positive rate of bacteria culture was 78.2%.Most of 141 strains were Gram-negative bacteria which accounted for 63.12%.After antibiotics being used for 7d,the bacteria positive rate declined from 78.2% to 38.2%.15d after antibiotics discontinuation,the bacteria positive rate rose from 38.2% to 69.2%.Bacteria detected from wound were generally resistant to common clinic antibiotics.Conclusion The pathogenic bacteria in chronic wound were mainly Gram-negative,and were generally resistant to common clinic antibiotics.
