About

Aaron E Chen, MD, is a Professor of Clinical Pediatrics (Emergency Medicine) at the Perelman School of Medicine at the University of Pennsylvania. He serves as an Attending Physician at the Children's Hospital of Philadelphia and is the Director of Emergency Bedside Ultrasound in the Emergency Department at Children's Hospital of Philadelphia. Additionally, he is the founder of the Pediatric Emergency Ultrasound Fellowship within the Division of Emergency Medicine at the same institution. His clinical expertise focuses on MRSA skin and soft-tissue infections and emergency bedside / point-of-care ultrasound. His research interests include the diagnosis and management of pediatric infections, particularly MRSA, and the application of point-of-care ultrasound in emergency medicine. Dr. Chen has contributed to the development of consensus definitions for focused assessment with sonography for trauma in children and has published extensively on ultrasound-guided procedures, pediatric emergency ultrasound education, and related topics.

  The rapid diagnosis of increased intracranial pressure is urgently needed for therapeutic reasons in neurocritically ill children, however this can rarely be achieved without invasive procedures. Point-of-care ultrasound of the optic nerve sheath diameter has been proposed as a non-invasive and reliable means to detect increased intracranial pressure in adults. Accordingly, clinicians may be able to use this technique to initiate early treatment and monitor the effectiveness of treatment in conjunction with other clinical examination and diagnostic modalities. Two meta-analyses and a systematic review have been published on this topic in adults. However, data on the correlation between optic nerve sheath diameter and intracranial pressure in neurocritically ill children are scarce. The aim of this review was to briefly describe what is being measured with point-of-care ultrasound of the optic nerve sheath diameter, summarize the most recent findings from adult literature, and provide an update of current work in children.

  OBJECTIVES: To evaluate if nurses can reliably perform ultrasound-guided peripheral intravenous catheter placement in children with a high success rate after an initial training period. A secondary aim was to analyze complication rates of ultrasound-guided peripheral intravenous catheters. METHODS: A database recorded all ultrasound-guided peripheral intravenous catheter encounters in the emergency department from November 2013 to April 2019 including the emergency department nurse attempting placement, number of attempts, and whether it was successful. Patient electronic medical records were reviewed for the time of and reason for intravenous removal.The probabilities of first-attempt successful intravenous placement and complication at successive encounters after an initial training period were calculated. These probabilities were plotted versus encounter number to graph best-fit logarithmic regressions. RESULTS: < 0.001). CONCLUSION: Nurses can reliably place ultrasound-guided peripheral intravenous catheters at a high success rate after an initial training period. First-attempt success rates were high and increased from 67% to 83% for the first 10 unsupervised encounters after training and remained high. The complication rate was low and did not change as nurses gained more experience.
