Abstract:Preterm infants, especially those born extremely or very prematurely, are at high risk for growth retardation and neurodevelopmental disorders. Regular follow-up after discharge, early intervention, and timely catch-up growth are important guarantees for improving the quality of life of preterm infants and improving the quality of the population. This article provides an overview of the research hotspots in follow-up management of preterm infants after discharge over the past two years, including follow-up modes, nutritional metabolism and body composition follow-up, growth pattern follow-up, neurodevelopmental follow-up, early intervention, etc., in order to provide clinical guidance and research ideas for domestic peers.
