Background: This study was performed for examining the neonatal results and aetiological factors of neonates with hydrops fetalis (HF) and determining the factors affecting mortality.
Methods:The medical records of liveborn neonates with HF who were admitted to a tertiary Neonatal Intensive Care Unit (NICU) in Konya, Turkey, between 2013 and 2019 were reviewed retrospectively. The demographic data, prenatal intervention, clinical findings, and results of the patients were recorded.Results: A total of 32.6% of the 46 liveborn HF infants had immune HF (IHF), while 67.4% had nonimmune HF (NIHF); there was prenatal diagnoses in 39 (84.7%) cases. Cordocentesis and blood transfusion (n = 14; 30.4%) were the prenatal diagnosis and treatment interventions with the highest rate. A total of 16 patients (34.7%) received in utero interventional treatment. It was determined that the mean gestational age was not associated with mortality; moreover, birthweight (BW), Apgar score and the need for mechanical ventilation affected mortality. Conclusion: The prognosis changes according to different etiologies of HF. However, despite the developments in neonatal care, mortality is still high in HF infants.
