Cardiac point-of-care ultrasound: Practical integration in the pediatric and neonatal intensive care settings

Abstract

Cardiac point-of-care ultrasound (POCUS) is a technology increasingly leveraged at the bedside by pediatric critical care and neonatology providers to identify real-time hemodynamic pathophysiology. We present a framework for (1) identifying the scope of cardiac POCUS within the clinical practice setting, (2) standardizing views for protocolized hemodynamic assessment relevant to pediatric critical illness and (3) integrating POCUS findings for therapeutic guidance. Within the review, we also discuss practical strengths and limitations to image acquisition and interpretation within the varied cardiac POCUS views. Finally, we explore unique considerations within the neonatal population. Conclusion: Cardiac POCUS is a technology and tool that reveals important real-time information at the bedside of the critically ill child and infant. Understanding strengths and limitations of cardiac POCUS views and protocolizing an approach to answer focused clinical questions provides a framework for training and translation to clinical care. What is Known: • Ultrasound technology is now ubiquitous among pediatric critical care and neonatology settings, and growing literature supports an expanded role in not only procedural but also diagnostic applications. • Cardiac POCUS influences provider perception of pathophysiology and changes clinical management. What is New: • Effective cardiac POCUS training and subsequent translation to clinical practice should improve when clinical questions and protocolized approaches to image acquisition are standardized within a specialty. • Cardiac POCUS views have strengths and limitations which must be recognized when assessing the hemodynamic profile of a child or neonate.
