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.

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. [ABSTRACT FROM AUTHOR]
