Effect of TIVA versus Sevoflurane on the incidence of post operative nausea and vomiting following day case gynaecology surgery

This study is looking at two different types of general anaesthesia for day-case (outpatient) gynaecological surgery — TIVA (total intravenous anaesthesia, where all medicines are given through a drip) versus sevoflurane (a gas inhaled to keep patients asleep). The study focuses on which method causes less post-operative nausea and vomiting (PONV), especially after the patient goes home, as nausea after surgery is very uncomfortable and a common reason for unplanned hospital stays. You may be eligible if: - You are 18 years or older - You are a woman having day-case gynaecological surgery under general anaesthesia You may NOT be eligible if: - You are classified as high anaesthetic risk (ASA IV or V) - You have allergies to the study medications - You are pregnant or breastfeeding - You have a psychiatric illness - You are having an epidural as part of your anaesthesia - You are planned to stay overnight in hospital Talk to your doctor about whether this trial might be right for you.
