摘要:

目的探讨梅县地区重症监护病房多重耐药菌(multi‐drug resistant organisms, MDRO)感染现状,为临床防治MDRO感染提供参考。方法回顾性分析中山大学附属第三医院2018年1月—2020年12月ICU收治的358例感染患者临床资料,所有患者均采集临床标本,进行病原菌培养。统计病原菌种类及株数,并进行药敏试验,分析MDRO耐药情况;同时依据是否发生MDRO感染分为MDRO感染组及非MDRO感染组,分析影响ICU患者MDRO感染的危险因素。结果358例ICU感染患者共检出MDRO感染142例,非MDRO感染216例,MDRO感染率为39.66%(142/358);其中142例MDRO感染患者共检出223株MDRO,革兰氏阴性菌占比最高,为77.58%(173/223),革兰氏阳性菌占比为22.42%(50/223)。革兰氏阴性菌分别为大肠埃希菌64株(28.70%)、肺炎克雷伯菌53株(23.77%)、铜绿假单胞菌35株(15.70%)、鲍曼不动杆菌21株(9.42%);革兰氏阳性菌均为金黄色葡萄球菌50株(22.42%);223株MDRO标本来源依次为痰液183株(82.06%)、中段尿22株(9.87%)、血液18株(8.07%)。常见MDRO中的大肠埃希菌、肺炎克雷伯菌及金黄色葡萄球菌对常规抗菌药物均呈广泛耐药性。多因素分析显示,年龄 ≥ 60岁、存在侵入性操作、住院时间 > 14 d、合并基础疾病、抗菌药物使用天数 > 14 d、抗菌药物种类三联及以上为影响ICU患者MDRO感染高危因素,差异有统计学意义(P< 0.05)。结论梅县地区ICU内MDRO感染类型以革兰氏阴性菌为主,且呈广泛耐药现象,临床需强化MDRO感染管控,对年龄大、存在侵入性操作、住院时间长等群体进行重点干预,以降低MDRO感染风险。

Abstract:

ObjectiveTo investigate the status of multi‐drug resistant organisms (MDRO) infection in intensive care unit (ICU) in Meixian District, and to provide important reference for the prevention and treatment of MDRO infection.MethodsThe clinical data of 358 patients with infection in ICU from January 2018 to December 2020 were analyzed retrospectively. All patients were collected for pathogen culture. The drug resistance of MDRO was analyzed, and the patients were divided into MDRO infection group and non-MDRO infection group according to MDRO infection. The risk factors of MDRO infection were analyzed.ResultsMDRO infection was detected in 142 out of 358 ICU infected patients, MDRO infection rate was 39.66% (142/358) , MDRO infection rate was 77.58% (173/223) in 142 out of 358 ICU infected patients, MDRO infection rate was 233, MDRO infection rate was 77.58% (173/223) , the proportion of Gram-positive bacteria was 22.42% (50223) , the Gram-negative bacteria were 64 strains of escherichia coli (28.70%) , 53 strains of Klebsiella pneumoniae (23.77%) , 35 strains of pseudomonas aeruginosa (15.70%) and 21 strains of acinetobacter Bowman (9.42%). All the Gram-positive bacteria strains were staphylococcus aureus 50 strains (22.42%) , 223 strains of MDRO were from sputum 183 strains (82.06%) , middle urine 22 strains (9.87%) and blood 18 strains (8.07%) escherichia coli, Klebsiella pneumoniae, and staphylococcus aureus, common MDRO strains, were extensively resistant to conventional antibiotics; multifactorial analysis showed that, age ≥ 60 years old, invasive operation, hospital stay > 14 days, combined basic diseases, days of antibiotics use > 14 days, triple antibiotics and above were the risk factors of MDRO infection in ICU (P< 0.05) .ConclusionThe main type of MDRO infection in ICU of Meixian District area is Gram-negative, and the MDRO infection shows extensive drug resistance. It is necessary to strengthen the control of MDRO infection in clinics to reduce the risk of MDRO infection.
