Multidrug-resistant infections are an increasingly common condition particularly in critical care units. This study aimed to determine the incidence and types of resistant bacteria acquired in a pediatric intensive care unit (PICU) of a university hospital.
A prospective study was conducted during the year 2016. All children aged below 16 years were studied for infection development and pattern of susceptibility to various groups of antibiotics.
A total of 264 patients were admitted to the PICU: 16 patients had community-acquired infection (CAI), 23 had hospital-acquired infection, and 24 patients had PICU-acquired infection (with 36 episodes) which is equivalent to 14.75 case/1,000 patient days. The study revealed high incidence of resistant organisms in the PICU but more important is the appearance of multi- and extreme drug-resistant bacteria in CAI. The study revealed that gram-negative bacteria were more prevalent in PICU, especially Klebsiella (30.5%), Acinetobacter baumanii (22.22%), and Pseudomonas (16.67%). Infection with resistant organisms in the PICU caused initial treatment failure and increased fourfold risk of mortality.
The incidence of resistant bacteria especially gram-negative pathogens was very high in the PICU. The top three resistant organisms of concern were Klebsiella, Acinetobacter, and Pseudomonas. This is a global concern that necessitates new strategies.
多重耐药感染是一种日益常见的情况,尤其是在重症监护病房。本研究旨在确定某大学医院儿科重症监护病房(PICU)中获得性耐药细菌的发生率和类型。
于2016年进行了一项前瞻性研究。对所有16岁以下儿童的感染发生情况及对各类抗生素的药敏模式进行了研究。
共有264例患者入住PICU:16例发生社区获得性感染(CAI),23例发生医院获得性感染,24例患者发生PICU获得性感染(共36次发作),相当于14.75例/1000患者日。该研究显示PICU中耐药菌的发生率很高,但更重要的是CAI中出现了多重耐药和泛耐药细菌。研究表明革兰阴性菌在PICU中更为普遍,尤其是克雷伯菌(30.5%)、鲍曼不动杆菌(22.22%)和铜绿假单胞菌(16.67%)。PICU中耐药菌感染导致初始治疗失败,并使死亡风险增加四倍。
PICU中耐药菌尤其是革兰阴性病原体的发生率非常高。最值得关注的三种耐药菌是克雷伯菌、不动杆菌和铜绿假单胞菌。这是一个全球性问题,需要新的策略。
