目的 :了解我院重型肝炎病人胆道感染的细菌分布及耐药特点。方法 :在X线介导下行十二指肠引流胆汁进行细菌培养及药敏试验。结果 :重肝病人引流的胆汁细菌生长的阳性率达 93 9% ,其中杆菌占 77 8% ,球菌 13 9% ,真菌 8 3 %。结论 :重型肝炎胆道感染的阳性率高 ,细菌仍以杆菌为主 ,要注意广谱抗生素应用导致二重感染 ;找出病原菌是治疗的关键。 Objective: To understand the bacterial distribution and drug resistance characteristics of biliary tract infection in patients with severe hepatitis in our hospital. Methods: The duodenal drainage bile was mediated by X-ray to conduct bacterial culture and drug sensitivity test. Results: The positive rate of bile bacteria drainage in patients with severe hepatitis was 93.9%, among which 77.8% were bacillus, 13.9% were cocci and 83% were fungi. Conclusion: The positive rate of biliary tract infection in patients with severe hepatitis is high. Bacteria are still mainly bacilli. Pay attention to the application of broad-spectrum antibiotics to cause double infection. Identifying pathogens is the key to treatment.
