This is a prospective study with the aim to determine specific patterns of burn wound bacterial colonisation and antimicrobial resistance profiles. There is a high incidence of infections and septicaemia in post-burn patients, which, in turn, are associated with high morbidity and mortality, a fact that compelled us to undertake this study. The study was conducted over a period 11 months, from 1 August 2014 to 30 June 2015, in 50 burn patients admitted in our burn unit. Wound cultures were taken after 72 hours of admission from all the patients, and then, empirical systemic antibiotics were administered. For wound cultures; 1 cubic cm tissue was taken and placed in aerobic and anaerobic culture vials and transported to the microbiology lab under all aseptic precautions as soon as possible. At the time of fever any time after 72 hours of admission, 16 ml of blood was drawn under all aseptic precautions. Both aerobic and anaerobic blood culture vials were filled with 8 ml of blood each and transported to the microbiology lab. The results of culture and sensitivity reports of 50 patients were recorded. The data obtained was analysed using appropriate statistical analytical tests. The most common organism responsible for bacteraemia is Pseudomonas (43%). Most of the strains of organisms isolated were resistant to commonly used antibiotics in the hospital; Pseudomonas was found 100% resistant to a combination of ampicillin + sulbactum, ceftriaxone and was most often sensitive to imipenem, amikacin and vancomycin. Methicillin-resistant Staphylococcus aureus (MRSA) was also found resistant to commonly used antibiotics like ceftriaxone, ampicillin + sulbactum and ceftazidime + calvulanic acid. Linzolid and vancomycin were effective in 83% and 100% cases, respectively. We conclude that similar institution-specific studies should be conducted, and such studies will be helpful in providing useful guidelines for choosing effective empirical therapy that will have a great impact on the prevention of infection and its complications in burn patients because of bacteraemia.
这是一项前瞻性研究,旨在确定烧伤创面细菌定植的特定模式和抗菌药物耐药谱。烧伤患者感染和败血症的发生率很高,这反过来又与高发病率和死亡率相关,这一事实促使我们开展这项研究。该研究于 2014 年 8 月 1 日至 2015 年 6 月 30 日期间在我们的烧伤病房进行,共纳入 50 名烧伤患者。所有患者在入院后 72 小时内采集创面培养物,然后给予经验性全身抗生素治疗。对于创面培养物,从每个患者身上采集 1 立方厘米的组织,分别放入需氧和厌氧培养瓶中,并在所有无菌预防措施下尽快送到微生物实验室。在入院后 72 小时任何发热时间,在所有无菌预防措施下抽取 16 毫升血液。每个需氧和厌氧血培养瓶各注入 8 毫升血液,并送到微生物实验室。记录 50 名患者的培养和药敏报告结果。使用适当的统计分析方法分析获得的数据。引起菌血症的最常见病原体是假单胞菌(43%)。分离出的大多数菌株对医院常用抗生素有耐药性;铜绿假单胞菌对氨苄西林+舒巴坦、头孢曲松 100%耐药,最常对亚胺培南、阿米卡星和万古霉素敏感。耐甲氧西林金黄色葡萄球菌(MRSA)也对头孢曲松、氨苄西林+舒巴坦和头孢他啶+克拉维酸等常用抗生素耐药。利奈唑胺和万古霉素的有效率分别为 83%和 100%。我们得出结论,应开展类似的机构特定研究,此类研究将有助于为经验性治疗提供有用的指导,对预防烧伤患者感染及其并发症产生重大影响,因为菌血症是感染的主要原因。
