Experience With the Crescent• Right Atrial Jugular Dual Lumen Catheter for Pediatric Venovenous Extracorporeal Membrane Oxygenation: A Case Series.

The Crescent dual lumen right atrial (RA) cannula has recently been introduced for the support of pediatric patients in need of venovenous extracorporeal membrane oxygenation (VV ECMO) support. We present the first pediatric case series illustrating utility of the Crescent RA cannula in the pediatric patient population at a single institution over a 10 month period. From December 2021 to August 2022, six pediatric patients were adequately supported on seven VV ECMO runs at our institution with the Crescent RA cannula.

Hirschsprung-associated enterocolitis: pathogenesis, treatment and prevention.

Hirschsprung-associated enterocolitis (HAEC) is a common and sometimes life-threatening complication of Hirschsprung disease (HD). Presenting either before or after definitive surgery for HD, HAEC may manifest clinically as abdominal distension and explosive diarrhea, along with emesis, fever, lethargy, and even shock. The pathogenesis of HAEC, the subject of ongoing research, likely involves a complex interplay between a dysfunctional enteric nervous system, abnormal mucin production, insufficient immunoglobulin secretion, and unbalanced intestinal microflora.
