【摘要】：目的探讨急性心肌梗死并发医院感染患者的病原菌分布,并分析感染对急性心肌梗死预后的影响。方法选择100例诊断为急性心肌梗死且并发医院感染的患者作为观察组,所有患者均留痰进行痰培养及药敏试验,同时选择100例诊断为急性心肌梗死未合并医院感染的患者作为对照组,对合并感染的患者预后影响进行分析。结果在观察组100例患者中共分离出病原菌128株,革兰阴性菌70株占54.7%,其中肺炎克雷伯菌最多,对亚胺培南、头孢哌酮/舒巴坦及头孢噻肟有较高敏感性;革兰阳性菌38株占29.7%,以金黄色葡萄球菌最多,对利奈唑胺及万古霉素有较高敏感性;真菌20株占15.6%,主要为白念珠菌,对伏立康唑有较高敏感性;观察组患者生存率37.0%,明显低于对照组患者70.0%,差异有统计学意义(P0.05)。结论并发医院感染严重影响急性心肌梗死患者生存状况。
[Abstract]:Objective to investigate the distribution of pathogenic bacteria in patients with acute myocardial infarction complicated with nosocomial infection and to analyze the influence of infection on prognosis of acute myocardial infarction. Methods 100 patients with acute myocardial infarction complicated with nosocomial infection were selected as observation group. Sputum culture and drug sensitivity test were performed in all patients. At the same time, 100 patients with acute myocardial infarction without nosocomial infection were selected as control group. Results 128 strains of pathogenic bacteria were isolated from 100 patients in the observation group, 70 strains of Gram-negative bacteria accounted for 54.7 strains, among which Klebsiella pneumoniae was the most sensitive to imipenem, cefoperazone / sulbactam and cefotaxime. Gram-positive bacteria accounted for 29.7B. Staphylococcus aureus was the most sensitive to linazolamine and vancomycin, and 20 strains of fungi, mainly Candida albicans, were highly sensitive to vancomycin, 20 strains of fungi were Candida albicans. The survival rate of the patients in the observation group was 37.0, which was significantly lower than that in the control group (P 0.05). Conclusion Nosocomial infection seriously affects the survival status of patients with acute myocardial infarction.
