Question
What is the severity of pulmonary hemorrhage in newborns, especially premature infants?
Answer
Generally, due to their underdeveloped organs, premature infants experience a more severe condition when suffering from pulmonary hemorrhage compared to full-term infants. This is mainly reflected in the following aspects: Firstly, premature infants are more prone to neonatal respiratory distress syndrome, which further affects lung function, making treatment more difficult. Secondly, premature infants have a poorer coagulation mechanism and fewer coagulation factors, resulting in a higher incidence of pulmonary hemorrhage. Moreover, the clinical manifestations of premature infants may be less obvious, leading to a later discovery time and a significantly lower success rate of rescue. Finally, the immune function of premature infants is not yet mature, resulting in a higher infection rate.
