Abstract
BACKGROUND: Extracorporeal membrane oxygenation has been widely used after paediatric cardiac surgery due to increasing complex surgical repairs in neonates and infants having complex CHDs. MATERIALS AND METHODS: We reviewed retrospectively the medical records of all patients with CHD requiring corrective or palliative cardiac surgery at King Abdulaziz University Hospital that needed extracorporeal membrane oxygenation support between November 2015 and November 2018. RESULTS: The extracorporeal membrane oxygenation population was 30 patients, which represented 4% of 746 children who had cardiac surgery during this period. The patients' age range was from 1 day to 20.33 years, with a median age of 6.5 months. Median weight was 5 kg (range from 2 to 53 kg). Twenty patients were successfully decannulated (66.67%), and 12 patients (40%) were survived to hospital discharge. Patients with biventricular repair tended to have better survival rate compared with those with single ventricle palliation (55.55 versus 16.66%, p-value 0.058). During the first 24 hours of extracorporeal membrane oxygenation support, the flow rate was significantly reduced after 4 hours of extracorporeal membrane oxygenation connection in successfully decannulated patients. CONCLUSION: Survival to hospital discharge in patients requiring extracorporeal membrane oxygenation support after paediatric cardiac surgery was better in those who underwent biventricular repair than in those who had univentricular palliation. Capillary leak on extracorporeal membrane oxygenation could be a risk of mortality in patients after paediatric cardiac surgery.
