Half a million babies are born prematurely in the United States every year. As doctors and parents make decisions about live-saving care in the first hours of a premature infant's life, they must grapple with profound ethical and scientific questions: Who should be saved? How aggressively should doctors try to salvage the life of a premature baby, who may be severely neurologically and physically impaired? What will that child's quality of life be like after millions of dollars are spent saving her? As a specialist in high-risk obstetrics and father of a premature child, Dr. Adam Wolfberg explores those profound questions at the beginning of life from the front lines of the NICU.
