Multicenter Study Clinical Trial
Effect of infusing fat emulsion into extracorporeal membrane oxygenation circuits.
Our objectives were to identify problems associated with the administration of fat emulsion by extracorporeal membrane oxygenation (ECMO) circuits, and gather information from other institutions on standards of practice and the complications associated with infusion of fat emulsion by ECMO to infants and children. In vitro analysis was performed using six circuits. Fat emulsion was infused into a prereservoir port at 3 ml/hour. ⋯ The most frequently reported problems with administration through the circuit were cracking of stopcocks, clogging and malfunction of the membrane oxygenator, agglutination of the emulsion, and increase in blood clot formation. Our results suggest that fat emulsion should be infused through a separate intravenous site whenever possible. Based on these results and current practices of most ECMO centers, a clinical trial is currently being conducted to provide additional information.
