【摘要】：目的探讨超声介入治疗医院感染的现状,通过对病原菌分布、耐药性及感染发生的危险因素进行分析,以制定相应的干预措施。方法选取经超声介入治疗的1 686例患者临床资料,送检标本采用BACTEC9000培养系统分离培养病原菌,依据K-B琼脂法进行药敏试验,结果判定按照美国临床实验室标准化委员会2005年版标准;采用SPSS13.0软件进行数据处理,分析感染发生的危险因素。结果超声介入治疗患者医院感染率为11.63%;共分离出病原菌204株,其中革兰阳性菌92株占45.10%,革兰阴性菌112株占54.90%;革兰阳性菌对乙酰唑胺和替考拉宁的耐药率较低,均6.00%,革兰阴性菌对美罗培南和亚胺培南的耐药率较低,均4.00%;年龄、住院时间、是否进行侵入性治疗、是否合并其他疾病、是否应用抗菌药物是患者发生医院感染危险因素。结论临床应根据发生感染的危险因素,控制感染的发生;当感染发生时,应立即进行细菌培养及药敏试验,根据结果选用耐药率低的抗菌药进行治疗。
[Abstract]:Objective to investigate the current situation of ultrasound intervention in the treatment of nosocomial infection, and to analyze the distribution of pathogenic bacteria, drug resistance and risk factors of infection in order to formulate corresponding intervention measures. Methods the clinical data of 1 686 patients treated by ultrasound interventional therapy were selected. The pathogens were isolated and cultured by BACTEC9000 culture system. The drug sensitivity test was carried out according to K-B Agar method. Results according to the 2005 edition of the American Clinical Laboratory Standardization Committee; The risk factors of infection were analyzed by SPSS13.0 software. Results the nosocomial infection rate was 11.630.204 strains of pathogenic bacteria were isolated, of which 92 strains were Gram-positive bacteria (45.10%) and 112 strains were Gram-negative bacteria (54.90%). The resistance rates of Gram-positive bacteria to acetazolamide and teicoplanin were 6.00 and 4.00, respectively, and those of Gram-negative bacteria to meropenem and imipenem were lower. Age, length of stay, invasive treatment, combination of other diseases and use of antibiotics are risk factors for nosocomial infection. Conclusion the occurrence of infection should be controlled according to the risk factors of infection, and the bacteria culture and drug sensitivity test should be carried out immediately when the infection occurs, and the antimicrobial agents with low drug resistance rate should be selected for treatment according to the results.
