RESUMEN
Background: Acute aortic dissection (AAD) is a rare condition but represents a time-sensitive disease for which a wrong and untimely identification in the triage phase could compromise the subsequent diagnostic, therapeutic path and patient's prognosis. The emergency nurse plays a crucial role in identifying and managing patients with possible AAD. The aim of this paper is to describe the emergency department nursing approach to critical patients with suspected hyperacute/acute AAD. Purpose: It is crucial to examine the emergency departments nursing approach to patients with suspected AAD. It is fundamental to have a rapid and standardized approach related to life-saving procedures, practices, and management of critical patients during the triage phase, with the assessment of the most common presentation of clinical signs and symptoms and patient management during each step in the emergency department. Conclusion: Early identification and diagnosis in ED allow prompt treatment that improves prognosis. The emergency nurse plays a crucial role in correctly identifying and managing patients with acute aortic dissection. High clinical suspicion from the triage stages, early diagnosis, monitoring, and initial clinical stabilization in the emergency department plays a key role while awaiting definitive treatment.
