Research summary
We wish to investigate the effect of our routine practice of drinking 30ml per hour of water pre-operatively prior to elective Caesarean section on the volume of liquid present in the stomach before surgery. Drinking 30ml per hour of water is routine practice at our institution as part of our enhanced recovery programme to maintain patient comfort in low-risk women due to receive regional anaesthesia for Caesarean section. These women arrive in hospital having adhered to national fasting guidance for general anaesthesia of 2 hours for clear fluids and 6 hours for solid food before commencing this minimally fasted regimen of 30ml water per hour until their operation. Using bedside gastric ultrasound, we aim to quantify the volume of liquid in their stomach on arrival (fully fasted) and prior to surgery after 30ml/hr (minimally fasted) in a paired cohort study to identify if this regimen has an overall effect on gastric volume. We will recruit women due to undergo elective caesarean section at UCH that are eligible for enhanced recovery and they will have two, non-invasive, bedside abdominal ultrasound scans prior to their surgery. Their fluid intake will be closely monitored and they will be asked to rate their level of hunger and comfort. Adverse outcomes of nausea or vomiting during the operative period will also be monitored. The study should run for approximately 3 to 6 months.
