Efficacy
Statistical methods / analysis
All analyses will be conducted on an intention to treat basis using standard statistical methods for categorical, count, continuous variables and time-to-event outcome data. Daily measures will be compared using repeated-measure linear mixed models. GAM models will be constructed using penalized regression splines and a thin plate smoother with each patient modelled as a random effect and with a fixed-effect covariates set including sex, age, hospital, WFNS severity, APACHE III score, time to intervention, method of securement, and sodium treatment methods.
The sample size will be fifty patients, based upon previous reports of fludrocortisone use and the high incidence of the use of sodium replacement therapies in this population

Summary
Brief summary
Aneurysmal subarachnoid haemorrhage (aSAH) is a devastating form of haemorrhagic stroke, that results from bleeding from an intracranial aneurysm. A common complication of aSAH is hyponatremia with a reported prevalence of between 35% to 77%.Our group has recently demonstrated that patients in whom the sodium concentration decreases over the ICU stay have a higher likelihood of a worse outcome at 6-months compared to those patients in whom the sodium concentration remains steady. Fludrocortisone is a synthetic adrenocortical steroid possessing activity which produces significant sodium and fluid retention. Previous studies of fludrocortisone have demonstrated a reduction in hyponatraemia and fluid loss, but these studies were underpowered to show a clinical outcome benefit. Fludrocortisone therefore has the potential to prevent the onset of hyponatraemia in aSAH and lead to improved outcomes; however, this has never been tested in an adequately designed trial. This proposal is for a Phase 2 trial to examine the effect of fludrocortisone administration on serum sodium concentrations, fluid balance and clinical outcomes measures in patients with aSAH.
