Complications After Preterm Birth: An Overview for Emergency Physicians

Nearly 65000 very low-birth-weight infants are born each year in the United States. Survival of these very premature infants has significantly increased over time with improvements in obstetric and neonatal care such as use of antenatal steroid and postnatal surfactant therapy, improved resuscitation and ventilation strategies, and use of early enhanced parenteral nutrition. However, a significant proportion of these infants develop either one or more complications of prematurity and may require ongoing care after their discharge. It is estimated that nearly 25% very low-birth-weight infants and as many as 80% extremely low-birth-weight infants have at least one readmission to the hospital. Many of these infants present to the emergency department with an illness that may be related to the complications of prematurity, and a basic understanding of these morbidities will allow emergency department physicians to provide optimal care to these infants. This article provides a brief summary of common morbidities seen in these high-risk infants.
