Paediatric and adult neurological point-of-care ultrasound: Review of the evidence, and the UK accreditation pathway.

Neurological emergencies such as stroke and traumatic brain injury are major contributors to morbidity and mortality in critically ill patients. These conditions frequently result in alterations in cerebral haemodynamics, including raised intracranial pressure, which require timely recognition and management to optimise outcomes. Neuro point-of-care ultrasound (NeuroPOCUS), incorporating transcranial Doppler (TCD), transcranial colour-coded duplex (TCCD) ultrasound, and optic nerve sheath diameter (ONSD) measurement, offers a non-invasive, bedside means of assessing cerebral physiology and is increasingly recognised as a valuable adjunct in neurocritical care. Despite the successful adoption of point-of-care ultrasound in critical care through established accreditation pathways such as FUSIC® and CACTUS®, the UK has lacked a dedicated framework for NeuroPOCUS. To address this gap, we have developed and launched a UK-specific NeuroPOCUS accreditation programme, combining structured theoretical teaching with supervised practical training. The pathway addresses the distinct needs of both paediatric and adult populations, combining theoretical learning with practical application. Core learning materials include neuroanatomy, Doppler principles, standardised insonation techniques, and interpretation of cerebral blood flow velocities and indices such as pulsatility (PI) and resistivity (RI). Supporting resources feature videos of transcranial colour-coded Duplex (TCCD) imaging in normal subjects and clinical case examples. Participants will complete a logbook of 50 supervised cases, facilitated by remote mentorship. A novel accreditation pathway provides an opportunity for further research into the use of NeuroPOCUS in neurocritical care. This article outlines the core techniques of NeuroPOCUS, the physiological insights it offers, key clinical applications, and the proposed accreditation pathway aimed at standardising practice and clinician training in the care of critically ill patients with neurological injury or dysfunction.
