The term “preterm infant” is different from “neonate”. The meaning of prematurity is not only the early delivery, but also the immature development of the functions associated with it. Like a farmer who breeds seeds, a seedling is a seedling when it is mature and rises out of the soil as a matter of course, while a sprout is an embryo when it is not yet mature; a newborn is a seedling, while a premature baby is a sprout. The characteristics of the bud embryo are different from those of the seedling, and the “premature infant” who is separated from the mother prematurely due to various dominant or recessive pathological factors is also different from the newborn who follows the natural physiological law of “ripening”. The immature organism’s ability to adapt to the outside world as an independent individual after separation from the mother, the diseases involved and their evolutionary mechanisms and processes, the medical care methods and prognosis are all different from those of newborns. With the rapid development of neonatology, the level of treatment of preterm infants is regarded as a sign of the level of neonatal medicine, and the treatment of preterm infants is paid more and more attention. Premature infants, especially very low/ultra-low birth weight preterm infants, are immature in body form and function, and successful treatment requires a long process, and the survival and subsequent quality of life of preterm infants are at stake. As a complete individual in a special stage of human life process, preterm infants may have diseases that involve every aspect of the body except for those specific to preterm infants, and their medical research and practice is no less important than any other discipline of clinical medicine. Premature infants are very small, so clinical diagnosis and treatment need to be careful, otherwise the difference is a thousand miles. Therefore, for neonatologists, preterm infants are a “touchstone”, preterm infants are a “book”; preterm infant medicine is a science; the treatment of preterm infants is a systematic project focusing on long-term survival quality, taking into account the many influencing factors and containing a wealth of medical It is a systemic project that focuses on long-term survival quality, takes into account many factors and contains a wealth of scientific and technical knowledge. ”Strategy”, also known as “strategy”, refers to the principles, guidelines and ways of working to achieve certain goals. It contains three important characteristics: one is foresight, from the beginning to focus on long-term goals; two is systematic, outlining a clear program line that takes into account a wide range of complex factors; three is scientific, a guide to follow and adapt to the objective laws inherent in the development of things. The purpose of discussing the “strategy of preterm infant treatment” is to trace the whole process of preterm infant treatment according to the pathological and physiological characteristics of preterm infants, to outline the overall outline of preterm infant treatment, and to sort out and summarize the key points and appropriate technologies for preterm infant treatment. In order to further improve the quality of preterm infant management, reduce the occurrence of comorbidities, and continue to improve the outcome of treatment to a great extent, the medical and nursing forces and appropriate technologies should be organized in a more comprehensive, rational and orderly manner. The development of modern medical technology has made a qualitative leap in the level of treatment for preterm infants. The vast majority of preterm infants can have a healthy future after careful treatment.
