In 1 room, the fellow is attempting to place a central venous catheter in a 5-year-old boy with presumed septic shock but has been unable to locate the femoral vein with her finder needle. In the next room lies a 7-year-old trauma patient. He is tachycardic with poor perfusion and abrasions on his chest. The team calls for a portable chest radiograph and begins a secondary survey.

In 1 room, the fellow is attempting to place a central venous catheter in a 5-year-old boy with presumed septic shock. Using bedside ultrasound, she makes adjustments with her finder needle until she sees it enter the femoral vein. In the next room lies a 7-year-old trauma patient. He is tachycardic with poor perfusion and abrasions on his chest. The team performs an extended focused assessment with sonography for trauma examination, which reveals free fluid in Morison' s pouch and no pneumothorax. A computed tomography scan of the abdomen is prioritized, and type O negative blood is ordered. The resident taps your shoulder. "Can I present a patient?" He describes a 15-year-old girl with lupus complaining of chest pain who is ill appearing, tachycardic, and short of breath. "I did a bedside ultrasound, and she has a pericardial effusion."In 2002, many pediatricians, including the authors, viewed point-of-care ultrasound as a tool used primarily by "general" emergency physicians, cardiologists, and obstetricians. The relevance to our pediatric patients seemed uncertain. Ten years later, the advantages that pointof-care ultrasound offers to those caring for ill, injured, and diagnostically challenging children are difficult to ignore. Although point-of-care ultrasound is relatively new to pediatrics, it is growing rapidly in subspecialty fields such as pediatric emergency medicine, critical care, and neonatology.1-3 The use of point-of-care ultrasound to guide invasive procedures, quickly focus the evaluation of critically ill patients, and reduce exposure to ionizing radiation are some of the factors driving the adoption of bedside ultrasound by pediatric physicians caring for the sickest and most complex pediatric patients.Still, pediatricians who finished training more than a decade ago likely did not receive instruction in point-of-care ultrasound because the relevance to general pediatric patients had not yet been demonstrated. What does point-of-care ultrasound afford pediatrics today? We believe AUTHORS:
