目的 对烧伤层流病房多重耐药菌感染的相关因素进行分析，通过护理干预来预防和减少烧伤病房多重耐药菌感染的发生。 方法 回顾性分析2011年1月－12月收治的629例烧伤患者，其中发生多重耐药菌感染74例，感染率为11.8%。 结果 感染部位：创面分泌物培养感染占70.2%，痰液标本培养感染占9.4%，血液标本培养感染占16.2%，其他占4.2%。感染病原菌：以金黄色葡萄球菌为主，占77.0%；鲍曼不动杆菌占4.2%，铜绿假单胞菌占10.8%，肺炎克雷伯菌占6.7%，真菌感染占1.3%。 结论 对发生医院内多重耐药菌感染的原因进行分析并及时采取相应的护理干预措施，及可行的医院感染管理控制措施，对烧伤患者预后有重要的意义，可有效降低院内感染率的发生。
ObjectiveTo explore the effects of burn ward cleaning methods on multi-drug resistant bacteria infection, in order to improve and optimize the cleaning process and method. MethodsFrom November 2012 to October 2013, the cleaning and disinfection methods in our burn wards were regarded as the traditional cleaning methods, and from November 2013 to October 2014, the cleaning and disinfection methods were called the improved cleaning methods (new system cleaning methods). By retrospective analysis, we compared the infection rates of multi-drug resistant bacteria before and after the implementation of the new system cleaning methods. ResultsNew system methods were used in the ward environment cleaning and disinfection. The infection rate of multi-drug resistant bacteria before and after the implementation of the new system cleaning methods were 12.414‰ and 5.922‰ respectively. The methicillin resistant Staphylococcus aureus infection rate was 7.286‰ and 3.718‰, and the carbon-resistant Pseudomonas aeruginosa infection rate was 2.699‰ and 0.689‰. Both differences were significant (P < 0.05). The carbon-resistant Acinetobacter baumanii infection rate was 2.429‰ and 1.515‰ before and after the implementation of the new methods with no significant difference (P > 0.05). ConclusionAdopting new system to carry out cleaning can effectively reduce the infection rate of multi-drug resistant bacteria in the burn ward, and it is worthy of clinical popularization and application.
Objective To investigate the risk factors of multidrug-resistant organism (MDRO) infection in patients with car accident injuries in intensive care unit (ICU), providing clinical guidance for reducing MDRO infection in car accident patients. Methods The clinical data of patients with car accident injuries in Sichuan Provincial People’s Hospital between January 1st 2019 and February 28th 2023 were collected, and the relevant data were analyzed retrospectively to explore the risk factors of MDRO infection. Results A total of 141 patients with car accident injuries were collected, of whom 30 had MDRO infection. The proportions of males (P=0.012), indwelling catheters (P=0.005), mechanical ventilation (P=0.001), length of hospital stay (P<0.001), and total treatment costs (P<0.001) in the infection group were higher than those in the non-infection group. Multiple logistic regression analysis showed that male [odds ratio (OR)=3.797, 95% confidence interval (CI) (1.174, 12.275), P=0.026], mechanical ventilation [OR=4.596, 95%CI (1.538, 13.734), P=0.006], and length of hospital stay≥20 d [OR=1.014, 95%CI (1.001, 1.028), P=0.037] were independent risk factors for MDRO infection in car accident patients. Conclusions Male, mechanical ventilation, and increased length of hospital stay are independent risk factors for MDRO infection in car accident patients. For such patients, the prevention and control measures of hospital infection should be strictly implemented to reduce the risk of infection.
