Comparison of an Isotonic Balanced Fluid, Sterofundin® , With 0.9% Saline in Traumatic Brain Injury(TBI)

Brain Injuries

Traumatic brain injury, isotonic balanced fluid

The main objective of this study is to compare the clinical outcomes of TBI patients receiving only Sterofundin or 0.9% saline as main fluid therapy.

Study Design: Prospective single centre double-blind randomized controlled trial Study endpoints/outcomes Primary outcomes: * 30 day mortality * Functional neurological outcomes at 6 months based on Extended Glasgow Outcome Scale (GOS-E) Secondary outcomes: * Acid-base and electrolyte balance * Daily mean change in intracranial pressure (ICP) * Episodes of intracranial hypertension * Duration of mechanical ventilation * Length of ICU stay and ICU mortality Study Duration: 2 years Site: UMMC. Departments involved: Emergency Medicine, Surgery, Anaesthesiology and Pharmacy Methodology. Investigators will assess patients admitted to the Emergency Department, UMMC, for eligibility. Randomisation: Investigators will randomize patients in a 1:1 ratio to either 0.9% saline intravenous fluid group or Sterofundin® intravenous fluid group. An independent statistician not involved with the research will perform a block of eight randomisation using computerised number generator list. Conduct of study The Department of Pharmacy will identically seal all 0.9% saline and Sterofundin® intravenous fluid bottles and label them, according to their type, as either A or B. The patients, investigators and medical and nursing staff will not be aware of the designation of the letters A and B to the fluids. Investigators will administer the study fluid will immediately after patient randomisation and this will last for 72 hours. Other general care of the traumatic brain injury patients from both study arms will continue as per Neurosurgical Unit protocol and Brain Trauma Foundation guidelines. Data handling Investigators will collect all data relevant to both primary and secondary outcomes (see also attached proforma): Statistical analysis Investigators will conduct students t test, Chi squared and the Mann-Whitney U test as appropriate. Investigators will adjust results with univariable and multivariable logistic regression and report their odds ratio. Investigators will present survival analysis using Kaplan Meier curves and compare them using log rank test.
