Summary
Brief summary
Postoperative nausea and vomiting remains a significant problem in modern anaesthetic practice. One of the most effective anti-sickness agents (antiemetics) available is a steroid drug: dexamethasone. Steroids are also used to supress the immune system and inflammation in the body. This immune supression can also predispose to the development of infection. We wish to investigate whether the small doses of dexamethasone used in anaesthesia affects the nature and function of important immune system cells known as lymphocytes.
