Hemorrhage in the newborn is either traumatic or spontaneous.
—When hemorrhage occurs during the first twenty-four hours after delivery it is usually traumatic. In the class of traumatic hemorrhages are to be included the following: Cephalohematoma, hematoma of the sternocleidomastoid muscle, hemorrhage beneath the skin, intracranial, intra-abdominal and intrathoracic. Intracranial hemorrhage, if extensive, causes death at birth, or the infant may breathe feebly for a few moments and die. If less extensive, there are no immediate symptoms, but paralysis later. Intra-abdominal hemorrhage can usually only be surmised, and in an infant large and strong at birth, dying within a few hours, with evidences of shock, intra-abdominal hemorrhage should be suspected; but the diagnosis can be confirmed only by autopsy. Hemorrhage of the lungs is certainly rare, but I have one case, reported herewith (Case 6).
—In spontaneous hemorrhage the blood may be from any mucous surface
