2021年9月16日 · EVD. The EVD has two major advantages: the ability to treat elevated ICP via CSF diversion and the ability to sample CSF. Note, though, EVDs are not the only way to accomplish CSF diversion. Lumbar drains can also be used for CSF diversion and can be used to give ICP data (PMID: 20953846) although EVDs are still considered the gold standard. If ...

2022年6月22日 · The EVD will be set to drain CSF when the CSF pressure exceeds a certain value equal to the height of the drainage apparatus (e.g., 5-15 cm H2O). Low pressure (e.g., ~5 cm H2O) will encourage fluid drainage.

Insertion of an External Ventricular Drain (EVD) is arguably one of the most common and important lifesaving procedures in neurologic intensive care unit. Various forms of acute brain injury benefit from the continuous intracranial pressure (ICP) monitoring and cerebrospinal fluid (CSF) diversion provided by an EVD.

External ventricular drain (EVD): A temporary system that allows drainage of cerebral spinal fluid (CSF) from the ventricles to an external closed system. Intracranial pressure (ICP) monitoring: A temporary device allowing measurement and recording of intracranial pressure.

An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.

EVD include intracranial pressure monitoring and therapeutic drainage of CSF. The major disadvantage is the increased risk of infection, which increases with longer duration of use. If you have not managed a patient with an EVD, it is important to seek guidance from experienced staff to demonstrate practices and elucidate other evidence-

The external ventricular drain provides continuous monitoring of intracranial pressure (ICP) and effective ICP reduction by a constant cerebrospinal fluid (CSF) release. Despite its high diagnostic and treatment potential, EVDs are also associated with a high rate of infections [ 1 , 2 , 3 , 4 , 5 ].

2023年6月23日 · EVD 的主要适应症是急性脑积水，这可能与不同的病理学有关，例如 SAH、脑实质内出血（伴或不伴脑室内受累）、感染、脑肿瘤和分流失败。 此外，脑外伤基金会关于严重 TBI 管理的指南包括将 EVD作为手术治疗和监测 ICP。 最先讨论的主题之一是最适合放置EVD 的环境。 通常在紧急情况下，许多中心在手术室 (OR) 以外的地方进行 EVD，例如急诊室 (ER) 或重症监护室 (ICU)。 多项研究（许多是回顾性研究）旨在比较在 OR 中接受 EVD 的患者与在 ICU 或 …

Following TBI, an EVD may serve both to monitor ICP and to divert CSF for decreasing elevated ICP. In the modern era, a fiber optic intraparenchymal monitor can be used if all that is needed is measurement of ICP, and most clinicians in the industrialized world adhere to the Brain Trauma Foundation guidelines that advocate use of some form of ...

2022年8月31日 · EVDs are indicated when CSF diversion and intracranial pressure monitoring are needed. There is variability in insertion, management, and removal of EVDs, as well as administration of intraventricular medications. More research is required to standardize EVD-related processes.
