Surgical procedures in neonates are functionally divided into those performed in the first week and those performed in the first month of life. Emphasis of presurgical stabilization before taking the newborn to the operating room has reduced the emergent nature of newborn surgeries (congenital diaphragmatic hernia, omphalocele). Exceptions include gastroschisis, which is usually attended to within 12 to 24 hours, airway lesions such webs that are causing significant airway obstruction, and acute subdural or epidural hematomas from traumatic delivery.
