Description of intervention(s) / exposure
The intervention group will begin a fasting regime the day before surgery which will involve cessation of solid foods at 2000 hours and cessation of fluids at 2200hrs. All patients will be registered on the morning surgery list. All patients will be overseeing adherence to the fasting regime ward nurse. Strategies used to monitor adherence to the intervention include regular observation. This must be finished by 2200 hours and nursing staff will monitor fluid input. The intervention group will consume 300 ml liquid carbohydrates (100 ml solution includes 22.5 maltodextrin and 2.5 g glucose) up to three hours before surgery and will be monitored by nurses.
