RESUMO
Treatment of gastroschisis often requires multiple surgical procedures to re-establish abdominal domain, reduce abdominal contents, and eventually close the abdominal wall. In patients who have concomitant respiratory failure requiring extracorporeal membrane oxygenation (ECMO), this process becomes further complicated. This situation is rare and only five such cases have been reported in the ECMO registry database. Management of three of the five patients along with results and implications for future care of similar patients is discussed here. Two patients had respiratory failure due to meconium aspiration syndrome and one patient had persistent acidosis as well as worsening pulmonary hypertension leading to the decision of ECMO. The abdominal contents were placed in a spring-loaded silastic silo while on ECMO and primary closure was performed three to six days after the decannulation. All three patients survived and are developmentally appropriate. We recommend avoiding aggressively reducing the abdominal contents and using a silo to conservatively reducing the gastroschisis while the patient is on ECMO therapy. Keeping the intra-abdominal pressure below 20 mm Hg can possibly reduce ECMO days and ventilator time and has been shown to decrease morbidity and mortality. Patients with gastroschisis and respiratory failure requiring ECMO can have good outcomes despite the complexity of required care.

Conventional treatment of respiratory failure involves positive pressure ventilation that can worsen lung damage. Extracorporeal membrane oxygenation (ECMO) is typically used when conventional therapy fails. In this study, we evaluated the use of venovenous (VV)-ECMO for the treatment of severe pediatric respiratory failure at our institution. A retrospective analysis of pediatric patients (age 1-18) placed on ECMO in the last 15 years (1999-2014) by the pediatric surgery team for respiratory failure was performed. Five pediatric patients underwent ECMO (mean age 10 years; range, 2-16). All underwent VV-ECMO. Diagnoses were status asthmaticus (2), acute respiratory distress syndrome due to septic shock (1), aspergillus pneumonia (1), and respiratory failure due to parainfluenza (1). Two patients had severe barotrauma prior to ECMO initiation. Average oxygenation index (OI) prior to cannulation was 74 (range 23-122). No patients required conversion to VA-ECMO. The average ECMO run time was 4.4 days (range 2-6). The average number of days on the ventilator was 15 (range 4-27). There were no major complications due to the procedure. Survival to discharge was 100%. Average follow up is 4.4 years (range 1-15). A short run of VV-ECMO can be lifesaving for pediatric patients in respiratory failure. Survival is excellent despite severely elevated oxygen indices. VV-ECMO may be well tolerated and can be considered for severe pediatric respiratory failure.
