Summary
Brief summary
Dexamethasone is a drug commonly given to prevent postoperative nausea and vomiting. It also has properties that dampen the body's immune response to infection. In this study, we propose to examine female patients undergoing breast surgery. These patients are at high risk of nausea and vomiting and routinely receive drugs to prevent this. We will give patients one of two drugs, either dolasetron or dexamethasone when they are under anaesthetic. Blood samples will be taken before and after the drugs to determine the effect that they have on the immune system. We hope to determine whether dexathasone has an effect on the body's immune system.
