Neonatal Hypoxic Respiratory Failure: Referral for ECMO

Year: 2024

Type: article

Abstract: Background: Neonatal hypoxic respiratory failure (HRF) secondary to PPHN (persistent pulmonary hypertension of the newborn) is an uncommon but life-threatening complication. Despite advances in therapeutic interventions, there are neonates who may require ECMO (extracorporeal membrane oxygenation), which improves survival. In establishing the capability of ECMO in transport in New South Wales, significant variation in referral thresholds and management of PPHN in referring hospitals has been noted. Aim: To review cases referred to the Newborn and paediatric Emergency Transport Service (NETS) for consideration of ECMO due to HRF in neonates. The aetiology of HRF, the number of retrievals and their short-term outcomes were reported. Methods: A retrospective audit of referrals to NETS (January 2019 to December 2022) of infants aged <28 days with HRF for ECMO. Patient demographics, management, advice at the time of call and the outcome are described. Results: The mean weight was 3511 g, mean gestation was 37.1 weeks and 69% of the patients were male. The main diagnoses were MAS/PPHN (50%), and there was variation in inotropes and ventilation strategies at the time of the referral. Six (25%) of the fifteen babies who were transported by NETS to paediatric intensive care were placed on ECMO at the referring hospital. A further six babies were stabilised at the referral centre following NETS co-ordinated specialist advice and did not require retrieval or ECMO. All the babies who received ECMO and survived had normal early development (<6 months) with normal head US or MRI imaging. Conclusions: Optimising ventilation and inotrope management can eliminate the need for ECMO prior to or following retrieval. Early referral for the consideration of ECMO and a collaborative discussion can assist in optimising conventional therapy, thus eliminating the need for ECMO. Neonates requiring ECMO for HRF have good survival rates with good short-term neurological outcomes.
