Cardiac POCUS in Pediatric Emergency Medicine: A Narrative Review

PURPOSE OF THIS REVIEW: The cardiac point of care ultrasound (POCUS) is among the most impactful examinations in the evaluation of an ill child. This paper will review the English-language literature on cardiac POCUS in the pediatric emergency department (PED), the adult emergency literature with relevance to pediatric emergency, and other pediatric cardiac studies outside pediatric emergency with relevance to PED detection of potentially emergent pediatric cardiac pathology. RECENT FINDINGS: Pediatric emergency physicians can reliably detect decreased left-sided systolic function and pericardial effusion using POCUS. Case reports show that pediatric emergency physicians have detected right-sided outflow tract obstruction, aortic root dilatation, and congenital cardiac disease using POCUS. Training for pediatric cardiac POCUS competency is feasible, and cardiac POCUS does not increase the burden on cardiology resources to the PED. SUMMARY: While cardiac pathology in children is relatively rare, pediatric cardiac POCUS can incorporate a broad curriculum beyond systolic function and the presence of pericardial fluid. Further research should assess pediatric emergency physician performance in the identification of a broader range of cardiac pathology.
