Medtronic Affinity Pixie™ Oxygenation System a Success in Beijing Hospital

Dr. Jinping Liu, Fuwai Hospital, Beijing, China, uses the Affinity™ Pixie Oxygenation System during a pediatric cardiac procedure.

Fuwai Hospital in Beijing City, China, became the first Chinese hospital to use the Medtronic Affinity Pixie™ Oxygenation System for pediatric cardiac surgery cases in July 2014. Since then, they have used it successfully on nearly 200 pediatric patients requiring congenital heart surgery. "We have used the Affinity Pixie™ Oxygenation System in a variety of pediatric cardiac cases from straightforward ventricular septal defect (VSD) repairs to more complex cases involving the transposition of the great arteries (TGA)," said Jinping Liu, Director of Pediatric Perfusion, Fuwai Hospital.

"The Affinity Pixie Oxygenation System's quick set up, ease of use, and enhanced port compatibility pleased the cardiac surgery perfusion team," added Liu. "It's important that we have confidence in the cardiopulmonary bypass technologies we use on our youngest and smallest patients."

Procuring blood for surgical procedures in China is a continual challenge since demand greatly exceeds supply, due in part to the low percentage of people who donate blood – just 0.92% in 2011. The World Health Organization (WHO) recommends that to maintain an adequate blood supply, approximately 1-3% of the population needs to donate blood.Besides this, several clinical studies have shown that blood priming for cardiopulmonary bypass (CPB) procedures for infant and neonate patients may cause adverse effects on the outcome. Based on this, Liu and her team committed to the study of non-blood priming. They were pleased that of the 144 pediatric cases (<20kg) her team performed between July 2014 and December 2014, 136 were non-blood priming (94.4%). "With its low 48 mL prime volume, the Affinity Pixie System is well suited for our pediatric surgery needs," noted Liu.

Delivering Performance and Flexibility for Pediatric Patients

The Affinity Pixie Oxygenation System delivers performance and versatility for neonates, infants and small children requiring cardiopulmonary bypass at flow rates up to 2.0 L/min. The system earned its CE Mark in May 2010, U.S. Food and Drug Administration (FDA) 510(k) clearance in October 2012, and most recently in China in July 2014.

The Affinity Pixie Oxygenation System features quick set up and custom device positioning and orientation, allowing it to be adapted to any pump set up using the Affinity Orbit™ Holder System. This provides flexible device positioning and port orientation to help reduce circuit tubing length and associated prime volume.
