Ultrasound-guided central venous catheter insertion in pediatric patients

In pediatric patients, central venous catheterization (CVC) is necessary for administration of fluids, drugs, high concentration electrolytes, vasopressors or inotropic drugs, transfusion, intravenous nutrition, and dialysis. Using an anatomical landmark for the CVC insertion may have a low success rate in children due to the positional variation between the deep vein and the landmarks, the small size of body and blood vessels, low insertion frequency, and operator skill. In order to improve the success rate, ultrasound guided CVC insertion is recommended in critically ill children. It is also expected to reduce mechanical complications, which are more common with subclavian CVC insertion. However, the association between the insertion site and the infection or thrombosis is unclear. Since thrombosis is relatively common, further studies are needed on the association between the incidence rate and insertion sites

Interfacility transport of critically ill children

Interfacility transport of critically ill children (transport) is a challenging component of pediatric critical care. The risk associated with the transport may be reduced by a specialized pediatric transport team, a screening tool for critically ill children, and a standardized handover between referring and referred physicians. Further research is necessary in Korea regarding the above measures for the safe and effective transport

Long-term changes in computed tomography and ultrasound utilization in a pediatric emergency department

Objective Many studies have proposed reducing unnecessary use of computed tomography (CT), and ongoing studies in pediatric populations are aiming to decrease radiation dosages whenever possible. We aimed to evaluate the long-term changes in the utilization patterns of CT and ultrasound (US) in pediatric emergency departments (PEDs). Methods This retrospective study reviewed the electronic medical data of patients who underwent CT and/or US in the PED of a tertiary referral hospital from 2000 to 2014. We compared the changes in utilization patterns of brain and abdominal CT scans in pediatric patients and analyzed changes in abdominal US utilization in the PED. Results During the study period, 196,371 patients visited the PED. A total of 12,996 brain and abdominal CT scans and 12,424 abdominal US were performed in the PED. Comparison of CT use in pediatric patients before and after 2007 showed statistically decreasing trends after 2007, expressed as the coefficient values of the differences in groups. The numbers of brain and abdominal CT scans showed a significant decreasing trend in children, except for abdominal CT in adolescents. The abdominal US/CT ratio in the PED showed a statistically significant increase (2.68; 95% confidence interval, 1.87 to 3.49) except for the adolescent group (5.82; 95% confidence interval, -2.06 to 13.69). Conclusion Overall, CT use in pediatric patients has decreased since 2007. Pediatric US use has also shown a decreasing trend; however, the abdominal US/CT ratio in pediatric patients showed an increasing trend, except for adolescents
