Insights
Point-of-care ultrasound (POCUS) offers noninvasive methods for assessing intracranial pressure in critically ill children. Optic nerve sheath diameter and Doppler indices of the central retinal artery are key POCUS techniques for predicting elevated intracranial pressure.
Area of Science:
- Pediatric critical care medicine
- Medical imaging
- Neurology
Background:
- Point-of-care ultrasound (POCUS) is increasingly utilized in pediatric emergency and intensive care settings.
- POCUS is integrated into physical examinations for real-time clinical data in critically ill children.
- Accurate monitoring of intracranial pressure is crucial for managing acute conditions in pediatric patients.
Purpose of the Study:
- To review the literature on POCUS techniques for predicting increased intracranial pressure (ICP) in pediatric patients.
- To detail the ultrasonographic measurement of optic nerve sheath diameter (ONSD) for ICP assessment.
- To describe the use of central retinal artery (CRA) Doppler indices as a surrogate for transcranial Doppler in evaluating ICP.
Main Methods:
- Literature review of studies employing POCUS for ICP assessment in pediatric populations.
- Focus on noninvasive techniques including ONSD measurement.
- Analysis of CRA Doppler indices for evaluating elevated ICP.
Main Results:
- ONSD measurement via POCUS is a noninvasive, radiation-free method to detect raised ICP.
- CRA Doppler indices provide valuable information similar to transcranial Doppler for ICP evaluation.
- These POCUS methods offer timely data to guide acute management strategies.
Conclusions:
- POCUS techniques, specifically ONSD measurement and CRA Doppler indices, are valuable tools for predicting increased ICP in pediatric patients.
- These methods can assist pediatric intensive care specialists in managing critically ill children.
- Further integration of these POCUS applications can enhance diagnostic capabilities at the bedside.
Abstract:
Point-of-care ultrasound has been widely used by clinicians at the bedside in recent years. Various types of point-of-care ultrasound practices are employed, especially in pediatric emergency rooms and intensive care units. Pediatric intensive care specialists perform point-of-care ultrasound virtually as a part of physical examination since it provides just-in-time vital clinical information, which could assist in acute management strategies in critically ill patients. Measurement of optic nerve sheath diameter using point-of-care ultrasound is a noninvasive and radiation-free technique to determine raised intracranial pressure. Ophthalmic artery and central retinal artery Doppler indices can be used as transcranial Doppler to assess raised intracranial pressure. The aim of this review was to provide detailed information on ultrasonographic measurements of optic nerve sheath diameter and central retinal artery Doppler indices as techniques of interest for predicting increased intracranial pressure in pediatric patients in view of the literature.
