肺、食管手术患者术后感染细菌调查

目的了解肺、食管手术后感染的致病菌分布和药物敏感性。方法监测951例肺、食管择期手术患者的术后感染致病菌和药敏情况,以及术后气管导管端痰液和胸腔引流管端胸水培养的意义。结果食管手术感染致病菌主要是绿脓杆菌、不动杆菌、凝固酶阴性葡萄球菌、甲型链球菌等。肺手术感染以金黄色葡萄球菌、甲型链球菌、不动杆菌、肺炎克雷伯氏菌为主。凝固酶阴性葡萄球菌、肠杆菌、绿脓杆菌、嗜麦芽窄食单胞菌耐药率高。结论细菌的抗生素耐药十分普遍,气管导管端痰液和胸腔引流管端胸水培养有助于术后抗生素的选择。

Bacterial investigation of postoperative infections in pulmonary and esophageal surgical patients

Objective To study the bacterial characteristics of postoperative infections for pulmonary and esophageal surgery.Methods Postoperative infection pathogens and bacterial susceptibility of 951 patients undergoing elective pulmonary and esophageal operations were observed.Sputum from the tips of tracheal tubes and thoracic effusion from the tips of chest tubes were cultured.Results Pseudomonas aeruginosa,Acinetobacter,coagulase negative staphylococcus,Streptococcus viridans were the main pathogenic bacteria of esophageal surgical infections,while Staphylococcus aureus,Streptococcus viridans,Acinetobacter,Klebsiella pneumoniae were the major postoperative infection pathogens in pulmonary surgery.The drug-resistance rate of coagulase negative staphylococcus,enteric bacilli,Pseudomonas aeruginosa,Stenotrophomonas maltophilia was high.Conclusion Antibiotic resistance was very common in thoracic surgery ward.Bacterial surveillance of sputum from the tips of tracheal tubes and thoracic effusion from the tips of chest tube were conductive to rational use of antibiotics.
