Regional anaesthesia has an important role in anaesthesia for day case surgery, either alone or as part of a balanced anaesthetic technique combined with general anaesthesia. The principal advantage is the provision of first-class postoperative analgesia which can be prolonged well into the postoperative period without danger to the patient. Other advantages include reduced perioperative morbidity, particularly postoperative nausea and vomiting, dizziness and sedation, all of which may lead to unexpected hospital admission. These problems are encounted most often with ophthalmic surgery and gynaecological surgery, both of which are frequently suitable for regional anaesthetic techiques. The use of regional anaesthetic techniques does not delay recovery times or discharge from hospital. The disadvantages of regional anaesthetic techniques include a small but significant failure rate, prolonged time to perform, and the fact that certain skills are necessary for its performance. There are a few contraindications to the use of regional anaesthesia but the majority of patients are suitable. These techniques are particularly appropriate for day case surgery in children and are usually used in combination with a light general anaesthetic.
