Revisiting dexamethasone use in the pediatric emergency department.

PURPOSE OF REVIEW: Dexamethasone is an essential treatment for common pediatric inflammatory, airway, and respiratory conditions. We aim to provide up-to-date recommendations for treatment of anaphylaxis, croup, coronavirus disease, multisystem inflammatory syndrome in children, and asthma with dexamethasone for use in the pediatric emergency department. RECENT FINDINGS: Literature largely continues to support the use of dexamethasone in most of the above conditions, however, recommendations for dosing and duration are evolving. SUMMARY: The findings discussed in this review will enable pediatric emergency medicine providers to use dexamethasone effectively as treatment of common pediatric conditions and minimize the occurrence of side-effects caused by gratuitous corticosteroid use.

POCUS in the PICU: A Narrative Review of Evidence-Based Bedside Ultrasound Techniques Ready for Prime-Time in Pediatric Critical Care.

Point-of-care ultrasound (POCUS) is an accessible technology that can identify and treat life-threatening pathology in real time without exposing children to ionizing radiation. We aim to review current evidence supporting the use of POCUS by pediatric intensivists with novice-level experience with bedside ultrasound. Current evidence supports the universal adoption of POCUS-guided internal jugular venous catheter placement and arterial line placement by pediatric critical care physicians. Focused cardiac ultrasound performed by PICU physicians who have completed appropriate training with quality assurance measures in place can identify life-threatening cardiac pathology in most children and important physiological changes in children with septic shock. POCUS of the lungs, pleural space, and diaphragm have great potential to provide valuable information at the bedside after validation of these techniques for use in the PICU with additional research. Based on currently available evidence, a generalizable and attainable POCUS educational platform for pediatric intensivists should include training in vascular access techniques and focused cardiac examination. A POCUS educational program should strive to establish credentialing and quality assurance programs that can be expanded when additional research validates the adoption of additional POCUS techniques by pediatric intensive care physicians.

Operational Innovation in the Provision of Pediatric Extracorporeal Membrane Oxygenation for Multisystem Inflammatory Syndrome in Children.

Treatment of multisystem inflammatory syndrome in children (MIS-C) can require significant critical care resources. Our aim is to alert mixed pediatric and adult hospitals worldwide of the possibility that pediatric and adult patients may simultaneously require cannulation to extracorporeal membrane oxygenation (ECMO) for MIS-C and severe COVID-19. We conducted a retrospective review of operations required to treat cardiogenic shock in 3 pediatric patients with a diagnosis of MIS-C admitted to a single medium-sized pediatric referral center located within a large academic medical center over a 14-day period. At this time, a large number of adult patients required ECMO for severe COVID-19 at our institution. Of the 11 pediatric patients who presented with MIS-C during the first surge of 2020, 2 patients required cannulation to venoarterial extracorporeal membrane oxygenation (VA-ECMO), and a third patient developed a life-threatening arrhythmia requiring transfer to a neighboring institution for consideration of VA-ECMO when our institution's ECMO capacity had briefly been reached. Pediatric referral centers located within institutions providing ECMO to adult patients with severe COVID-19 may benefit from frequent and direct communication with their adult and regional colleagues to devise a collaborative plan for safe and timely provision of ECMO to patients with MIS-C as the ongoing pandemic continues to consume this limited, lifesaving resource.

Ventricular tachycardia after naloxone administration in an adolescent.

Naloxone is a medication with a largely benign safety profile that is frequently administered in the emergency department to patients presenting with altered mental status. Ventricular tachycardia has been reported after naloxone administration in adult patients with prior use of opiate or sympathomimetic medications. However, no such reports exist in the pediatric population or in patients who have no known history of opiate or sympathomimetic medication use. We describe a case of ventricular tachycardia after naloxone administration in a 17-year-old male with no known prior use of opiate or sympathomimetic agents who presented to the emergency department with altered mental status of unknown etiology. Emergency physicians may wish to prepare for prompt treatment of ventricular arrythmias when administering naloxone to pediatric patients presenting with altered mental status.

Adult COVID-19 Patients Cared for in a Pediatric ICU Embedded in a Regional Biothreat Center: Disease Severity and Outcomes.

The objective of this study was to describe the clinical characteristics and outcomes of adult coronavirus disease 2019 (COVID-19) patients admitted to a pediatric intensive care unit (PICU), with assessment of respiratory clinical severity and outcomes when cared for by pediatric intensivists utilizing specific care processes. We conducted a retrospective cohort study of adult patients admitted to the 14-bed PICU of a quaternary referral center during the COVID-19 surge in Boston between April and June 2020. A total of 37 adults were admitted: 28 tested COVID-19 positive and 9 tested COVID-19 negative. Of the COVID-19-positive patients, 21 (75%), were male and 12 (60.7%) identified as Hispanic/Latino. Comorbidities in the patients included diabetes mellitus (39.3%), hyperlipidemia (39.3%), and hypertension (32.1%). Twenty-four (85.7%) required mechanical ventilation, in whom the lowest median ratio of arterial oxygen partial pressure to fractional inspired pressure was 161.5 (141.0 to 184.5), the median peak positive end-expiratory pressure (PEEP) was 14 (12.0 to 15.8) cmH2O and 15 (62.5%) underwent an optimal PEEP maneuver. Twelve (50%) patients were proned for a median of 3.0 (3.0 to 4.8) days. Of the 15 patients who were extubated, 3 (20%) required reintubation. Tracheostomy was performed in 10 patients: 3 after extubation failure and 7 for prolonged mechanical ventilation and weakness. Renal replacement therapy was required by 4 (14.3%) patients. There were 2 (7.1%) mortalities. We report detailed clinical outcomes of adult patients when cared for by intact pediatric critical care teams during the COVID-19 pandemic. Good clinical outcomes, when supported by adult critical care colleagues and dedicated operational processes are possible.
