Abstract:
Background:Extracorporeal membrane oxygenation (ECMO) is the only treatment option that can stabilize patients with congenital diaphragmatic hernia (CDH) with severe pulmonary hypertension. This study assessed the effects of a multidisciplinary ECMO team approach (META) as part of a quality improvement initiative aimed at enhancing the survival rates of neonates with CDH.
Methods:The medical records of infants with CDH treated at a tertiary center were retrospectively reviewed. Patients were categorized into two groups based on META implementation. The META group (P2) were given key interventions, including on-site ECMO management within the neonatal intensive care unit (NICU), use of venoarterial modality, ECMO indication as a priority even before the use of inhaled nitric oxide, and preplanned surgery following ECMO discontinuation. These approaches were compared with standard protocols in the pre-META group (P1) to assess their effects on clinical outcomes, particularly in-hospital mortality.
Results:Over a 16-year period, 322 patients were included. P2 had a significantly higher incidence of non-isolated CDH and higher rate of cesarean section compared with P1.Moreover, P2 had delayed time to surgical repair (9.4 ± 8.0 days) compared with P1 (6.7 ± 7.3 days) (P = 0.004). The overall survival rate at NICU discharge was 72.7%, with a significant improvement from P1 (66.3%, 132/199) to P2 (82.9%, 102/123) (P = 0.001). Among the 68 patients who received ECMO, P2 had significantly lower baseline oxygenation index and serum lactate levels before ECMO cannulation than P1. The survival rate of patients who received ECMO also remarkably improved from P1 (21.1%, 8/38) to P2 (56.7%, 17/30).Subgroups who could be weaned from ECMO before 2 weeks after cannulation showed the best survival rate.
Conclusion:META significantly improved the survival rate of newborn infants with CDH.Further interventions, including prenatal intervention and novel ECMO strategies, may help improve the clinical outcomes and quality of life.
