Point-of-care ultrasound for children.

Most diseases in children are acute, and ultrasonography should be performed in emergency cases rather than X-ray or computed tomography (CT) as children are more sensitive to radiation than adults. Therefore, point-of-care ultrasound (POCUS) is especially useful in children. The target organs of pediatric ultrasound are the same as in adults, and the infant brain can also be observed with ultrasound because the fontanel magna is still open. However, there are a number of points that physicians should be aware of regarding pediatric POCUS. There are some diseases specific to children, which are not found in adults. A higher frequency probe and higher frame rate are needed for children than for adults because of their small body size and rapid heart rate. Infants are not compliant, which necessitates the use of various measures to ensure that they remain still during the imaging examination. Pediatric POCUS is useful not only for diagnosis but also to ensure the safety of medical procedures, which is usually more difficult in children than in adults. POCUS has become a powerful tool for improving the success of such procedures and patient safety. The usefulness of POCUS is clearly evident, and it is being widely adopted across all disciplines in clinical medicine. Nevertheless, adoption of pediatric POCUS has been limited, and therefore educational programs for pediatric POCUS are needed.
