[POCUS in the emergency department: some nervous system applications]

Point of care ultrasound (POCUS) is used daily to diagnose and treat patients in emergency medicine. This article aims to demonstrate its utility focusing on central and peripheric nervous system pathologies frequently encountered in the emergency department such as difficult lumbar puncture, pain relief for proximal fracture of the femur and the detection of intracranial hypertension. Taught by well trained professionals the learning curve for performing these interventions safely is quick. The developmental potential for peripheral nerve blocks in emergency departments is high, especially for the fascia iliaca block.
