OBJECTIVE: To determine the effects continuous infusions of hypertonic saline (3% NaCl) on intracranial pressure (ICP) control and describe the physiologic effects of hypertonic saline administered to closed head injury children.
DESIGN: Retrospective chart review.
SETTINGS: Pediatric intensive care unit of a children's hospital.
PATIENTS: Sixty-eight children with closed head injury.
INTERVENTIONS: Intravenous infusion of 3% hypertonic saline to increase serum sodium to levels necessary to reduce ICP < or =20 mm Hg.
MEASUREMENTS AND MAIN RESULTS: The patients enrolled had similar Injury Severity Scores. Treatment effectively lowered ICP in these patients and ICP was under good control a majority of the time. Only three patients (4%) died of uncontrolled elevation of ICP. No adverse effects of supraphysiologic hyperosmolarity such as renal failure, pulmonary edema, or central pontine demyelination, were noted.
CONCLUSIONS: Hypertonic saline administration to children with closed head injury appears to be a promising therapy for control of cerebral edema. Further controlled trials are required to determine the optimal duration of treatment before widespread use is advocated.
