Use of centrifugal pump and extracorporeal membrane oxygenation as cardiopulmonary support in pediatric cardiovascular surgery

Use of centrifugal pump and extracorporeal membrane oxygenation as cardiopulmonary support in pediatric cardiovascular surgery

Arquivos Brasileiros de Cardiologia 90(4): 216-220

Extracorporeal membrane oxygenation is a well-documented resuscitation method in patients with severe hemodynamic and/or respiratory impairment. To describe several aspects related to the use of extracorporeal membrane oxygenation in a pediatric heart center and determine its immediate and late outcomes. Between October 2005 and January 2007, 10 patients who were submitted to pediatric cardiac surgery underwent extracorporeal membrane oxygenation implant. Median age was 58.5 days (40% neonates) and median body weight was 3.9 kg. Circulatory assistance was initiated aiming at the recovery and the weaning protocols followed daily clinical and echocardiographic criteria. Support was discontinued when transplant was contraindicated, when the patient was unable to recover or when survival was considered to be limited by a multidisciplinary team. Extracorporeal membrane oxygenation was employed after corrective or palliative heart surgery in 80% and preoperatively in the remaining ones. It was most often indicated for irresponsive hemodynamic instability (40%), post-cardiotomy shock (20%) and post-cardiac arrest (20%). The mean duration on support was 58 +/- 37 hours. Weaning was successfully in 50% of the cases and 30% were discharged home. Actuarial survival was 40%, 30% and 20% at 30 days, 3 months and 24 months, respectively. Extracorporeal membrane oxygenation is an effective and useful tool for the resuscitation of patients presenting severe hemodynamic and/or respiratory failure in the perioperative period of pediatric cardiovascular surgery.
