Objective: To investigate the relationship between the type of hyperosmolar therapy used in treating elevated intracranial pressure and the outcome of children with severe traumatic brain injury (TBI).  Two outcomes were measured, length of stay in ICU (ICU LOS) and disposition status at discharge.

Design: A retrospective, descriptive correlation design.

Setting: Level 1 pediatric trauma center in Southern California.

Patients: Children 8 to 18 years old admitted with isolated severe TBI (Glasgow Coma Scale score on admission 3-8) between January 2003 and January 2009. All these children had a documented abnormal head computed tomography scan (CT scan) on admission.  Children with increase intracranial pressure were treated with either Mannitol, 3% NaCl, or combined therapy of Mannitol and 3% NaCL 

Interventions: None.

Measurements: Children (n=96) admitted with isolated severe TBI had a median age of 13 years and documented brain injury on CT scan. The median GCS was 3 (range 3-8) on arrival to the Emergency room as well as at the time of ICU admission. Children were divided into 4 groups depending on the  type of treatment used. Study outcome were neurological disposition status on discharge as measured using a modified Pediatric Cerebral Performance Category scale (PCPC) and Length of stay (LOS) in ICU. 

Results: Significant relationship was documented between the type of hyperosmolar therapy used and LOS in ICU.  Children who received Mannitol had the shortest LOS and the highest mortality rate of 80% while the group who received 3% NaCl  had the longest LOS in ICU.  The group who received combined therapy of Mannitol and 3%  NaCl  had the lowest mortality rate which may suggest of better modalities to manage increased ICP’s
