Update on Intensive Care Unit Management of Stroke

Abstract

In this review, we provide an update on the intensive care unit (ICU) management of ischemic stroke. Over the last decade, new evidence has led to rapid changes in the early management of patients admitted with acute ischemic stroke. Nevertheless, stroke remains a leading cause of disability. Consequently, a significant number of patients with acute ischemic stroke require ICU level care. The most frequent reasons for ICU admissions are large infarction with potential swelling, reduced level of consciousness, secondary hemorrhagic transformation, acute symptomatic seizures or respiratory failure and stroke-related disorders of the brain-heart interaction. Moreover, there is an increasing number of patients receiving intravenous thrombolysis or mechanical thrombectomy with a subsequent need of ICU monitoring. Several studies have shown that the implementation of specialized neuro-intensive care teams help to improve functional outcome after acute ischemic stroke. The main goal in the ICU management of stroke patients is to prevent secondary brain injury. To this end, a comprehensive approach to optimize systemic physiological homeostasis, control intracranial pressure, cerebral perfusion, hemodynamic and respiratory parameters is needed. Here, we summarize recent advances in invasive and non-invasive neuro-monitoring, decision making in decompressive neurosurgery for large supratentorial or cerebellar infarction, specific cardiorespiratory management, nutrition, temperature management and mobilization strategies in ischemic stroke.
