Variables will be assessed for normality and log-transformed if appropriate. Baseline comparisons will be performed using Fisher’s exact tests and reported as n (%). Continuous normally distributed variables will be compared using Student t-tests and reported as means (standard deviation), while non-normally distributed data will be compared using Wilcoxon rank-sum tests and reported as medians [interquartile range].

Summary
Brief summary
The use of diuretics in critically ill patients is widespread. Indications include the management of volume overload, maintenance of acid-base balance and potassium homeostasis. Commonly used diuretics include frusemide and acetazolamide. Despite the common use of these drugs there is no high quality evidence available comparing the effect of these drugs on the haemodynamic status and metabolic status of critically ill patients.

We aim to evaluate the comparative effect of a standard dose of intravenous frusemide vs a standard dose of acetazolamide in critically ill patients. We plan to enrol a total of twenty-four patients in whom a decision has been made to administer a diuretic. These twenty-four patients will then be randomly assigned to receive a single dose of either frusemide of acetazolamide. To understand the effect of the diuretic administration, we will retrieve routinely recorded patient demographic data, haemodynamic data (such as blood pressure, heart rate, central venous pressure and cardiac output), data from the arterial blood gas samples (serum creatinine, sodium and potassium) as well as urine from the patient’s existing indwelling urinary catheter.

The results of this study will provide insight into the effects of these two diuretics on electrolyte imbalances and the haemodynamic status of critically ill patients.
