Neurocritical care patients requiring external ventricular drainage are at risk for the development of a device-related infection. Infection rate of external ventriculostomy catheters is high with reported incidences ranging from 5% up to more than 20%. Nosocomial ventriculitis or ventriculomeningitis are potential life-threatening conditions which may contribute to a permanent adverse outcome of the patient. Reducing morbidity and mortality is strongly dependent on prompt diagnosis and on the initiation of appropriate antiinfective therapy.
Management of nosocomial ventriculitis is challenging and needs to consider the most likely pathogens involved, local resistance patterns, the nature of the underlying disease, patient factors such as age, comorbidity, and immune status. Further, decisions on catheter exchange and the type and duration of systemic or local antimicrobial therapy have to be made. Because so many factors have to be taken into account, it is evident that the diagnostic and therapeutic approach to nosocomial ventriculitis is difficult to standardize. Staphylococci are the pathogens most frequently identified in nosocomial ventriculitis. Therefore, initial treatment with an antistaphylococcal agent with adequate cerebrospinal fluid penetration may be considered as first-line therapy for this infection.
In the review of a contemporary case we will discuss important issues in the management of device-related ventriculitis.
需要进行体外脑室引流的神经重症监护患者存在发生与设备相关感染的风险。体外脑室造瘘管的感染率很高,报告的发生率从5%到超过20%不等。医院获得性脑室炎或脑室脑膜炎是潜在的危及生命的疾病,可能导致患者出现永久性不良后果。降低发病率和死亡率很大程度上取决于及时诊断和启动适当的抗感染治疗。
医院获得性脑室炎的管理具有挑战性,需要考虑最可能涉及的病原体、局部耐药模式、基础疾病的性质、患者因素,如年龄、合并症和免疫状态。此外,还必须就导管更换以及全身或局部抗菌治疗的类型和持续时间做出决定。由于需要考虑如此多的因素,显然医院获得性脑室炎的诊断和治疗方法难以标准化。葡萄球菌是医院获得性脑室炎中最常鉴定出的病原体。因此,对于这种感染,可考虑使用具有足够脑脊液穿透力的抗葡萄球菌药物进行初始治疗作为一线治疗。
在回顾一个当代病例时,我们将讨论与设备相关的脑室炎管理中的重要问题。
