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.
