Extracorporeal Membrane Oxygenation
Conditions
Brief summary
Since the 1970s, extracorporeal membrane oxygenation (ECMO) support has been used to support gas exchange for children with severe acute respiratory failure who fail mechanical ventilation. ECMO is more expensive than each of these other procedures.But its action is unclear
Detailed description
Since 1974, eight randomized controlled trials have been reported in ECMO for respiratory failure, and none have included non-neonatal pediatric patients. Cochrane systematic reviews of this evidence concluded that ECMO for neonatal respiratory failure had a survival advantage, but there was insufficient evidence to demonstrate a survival advantage for ECMO used to support respiratory failure in adults. Moreover, these trials were performed prior to 2009, and since then advances in ECMO technology have enhanced the delivery of ECMO support, and new research has changed conventional management of severe acute respiratory distress syndrome (ARDS)
Interventions
the patients with severe respiratory failure were supported by ECMO
the patients with severe respiratory failure were supported by conventional mechanical ventilation
