Head injuries in infants and young children.

Head injury in infants and young children may produce lesions that are relatively unique for this age group. The uniqueness is generally due to the structural immaturity of the skull, meninges and brain."Derby-hat" and diastatic fractures are common in this age group. Spurious meningoceles result from tearing of the dura which is closely adherent to the skull. The syndrome of "delayed" concussion is more commonly manifested in children. Extradural and subdural hemorrhage may develop from lacerations of the major venous sinuses. A classical extradural hematoma may occur in the absence of fracture across meningeal arterial channels. The management of patients with head injury has been improved by the more frequent use of tracheotomy, hypothermic techniques and drugs of the "lytic cocktail." Solutions of urea in 10 per cent invert sugar are administered intravenously to control cerebral edema in selected patients.
