Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All patients receive 5 ml/kg of 0.9% sodium chloride as a standard fluid loading regime.
The intervention group receives a further 10 ml/kg of 0.9% sodium chloride intravenously.

The intravenous fluid is administered until each patient has reached the specific amount calculated by thier weight. The spinal anaesthesia is performed once the fluid loading and the transthoracic echocardiography has been completed.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment is achieved by using numbered sealed opaque envelopes which are only opened prior to study protocol commencing.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
The blinded personnel are as follows. The anaesthetist administering the anaesthesia to the patient. The anaesthetist or echocardiographer who is preforming the transthoracic echocardiogram. The anaesthetists who are reviewing the echocardiogram, assessing outcomes and analysing results. The unblinded personell are the research nurses who will be administering the treatment.

Summary
Brief summary
The primary purpose of this study is to find out what dose of intravenous fluid maintains enough fluid volume in the body after a spinal anaesthetic. Particpiants in this study are randomly assigned to have a high dose of intravenous fluid or a low dose of intravenous fluid. We find out how much fluid is in the body by doing an ultrasound of the heart before the the intravenous fluid is given, after the intravenous fluid is given, after the spinal anaesthetic is given and at the end of the operation.
