Outcomes of extracorporeal membrane oxygenation treatment post open congenital heart surgery
Main Article Content
Abstract
Objective: ECMO (Extra-Corporeal Membrane Oxygenation) is a technique that temporarily supports heart and lung function by a cardiopulmonary bypass system to treat patients who have failed to respond to the conventional treatments for cardiac or respiratory after congenital heart surgery. The objective of this study is to evaluate the outcomes of ECMO treatment post congenital heart surgery at the National Children's Hospital.
Subjects and methods: Descriptive, cross-sectional research method on 63 ECMO patients post open heart surgery from January 1, 2017 until August 30, 2023 at the Department of Surgical Cardiovascular Intensive Care, Cardiovascular Center, National Children's Hospital.
Results: Of 63 patients analyzed, the median age of the study group was 1.6 months, 88,9% of patients were children younger than 12 months old; median weight is 3.6 kg. The success rate of ECMO weaning was 55,6%. Overall survival of the cohort was 42,9%. The mean ECMO duration was 5,8 (IQR, 3,7-10,6) days, the mean hospital stay was 31 (IQR, 21-50) days, the mean ICU stay was 19 (IQR, 13-29) days. Mechanical complications during ECMO support include cannula bleeding and circuit thrombus. Acute kidney injury, hypertransaminase, and DIC (disseminated intravascular coagulation) are the most common patient-related complications during ECMO.
Conclusion: ECMO is a viable rescue strategy for cardiac surgery patients with ECMO weaning rate and survival rate were 55,6% and 42,9%, respectively, nearly equivalent to other heart centers.
