Plain English Summary
Background and study aims
Traumatic Brain Injury (TBI) is an injury to the brain caused by a trauma to the head (head injury). There are many possible causes, including road traffic accidents, assaults, falls and accidents at home or at work. Since TBI is a major health problem all efforts are being made to improve the outcomes of TBI victims. None of the TBI management guidelines addresses the fluid balance
Who can participate?
Patients aged 14 or above with severe TBI
What does the study involve?
Our study will have two groups with random assignment. In one group we will treat the patients following our ICU protocol which is adopted from Brain Trauma Foundation guidelines.
The second group will also follow the same protocol of management, and will be treated exactly the same way, but we will aim for maintaining a 24 hours balance of +/- 500 ml, while not interfering with the management hemodynamic targets, this will be done in the first 7 days after the trauma.
Upon ICU discharge we will evaluate the patients outcome using a score that ranges from 1 - 5 for the functionality of the patient (5 is best, 1 is worst).
Our hypothesis is that maintaining a balance of fluids will result in better outcomes.
What are the possible benefits and risks of participating?
Possible benefits include achievement of favourable Glasgow Outcome Score (4 or 5) upon ICU discharge, fewer ventilator days and thus fewer complications related to mechanical ventilation and less ICU and hospital stay. We are expecting no risks more than would be expected for a critically ill patient treated in ICU

Isolated, non penetrating severe traumatic brain injury (GCS < 9)
The study will recruit patients aged 14 or above (14 is the age of adulthood in Saudi Arabia) who are victims of severe TBI (GCS < 9) within 24 hours of the incidence of trauma. The main intervention of the study is controlling the fluid balance in the first 7 days to keep it ± 500 ml /day as compared to no interference with balance in the control group. Otherwise, both groups are treated similarly, according to our unit protocol adopted from guidelines of Brain Trauma Foundation.
Intervention: Maintaining a 24 hours balance of +/- 500 ml , for the first 7 days. While following the TBI protocol as per the guidelines. Daily balance may be controlled using diuretics, and if needed vasopressors to maintain hemodynamic targets.
Control: This group also follows the TBI protocol as per the guidelines, except there is no interference with the fluid balance
