Sipping water versus carbohydrate drinks while waiting for an elective caesarean
Official title: Comparison of 'Sip Til Send' Regimens Prior to Elective Caesarean Delivery Using Bedside Gastric Ultrasound: a Randomized Study Comparing Water With Carbohydrate-rich Drink
Run by The Rotunda Hospital · NCT07407530 · Data updated 2026-11-12
This will test whether sipping a carbohydrate drink instead of water while waiting for an elective caesarean changes stomach contents and improves recovery for pregnant women having caesarean delivery under regional anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Pregnant women booked for elective caesarean under regional anaesthesia who have adhered to standard fasting guidance and are eligible for Sip Til Send.
✕Probably not a fit
Women needing general anaesthesia, emergency caesarean, with BMI over 40, prior upper gastrointestinal or bariatric surgery, insulin-dependent diabetes, gestational diabetes, or those whose stomach cannot be visualized on ultrasound are unlikely to benefit or be eligible.

What this trial studies
This is a prospective, randomized, single-blinded trial comparing two 'Sip Til Send' approaches: a water group and a carbohydrate drink group for women awaiting elective caesarean delivery. Participants may sip up to one cup (170 ml) per hour while in hospital, and bedside gastric ultrasound will be used before delivery to document stomach contents. Healthcare workers and investigators are blinded to group allocation, though participants cannot be blinded. Patient-reported recovery measures will be collected after delivery to compare comfort and recovery between groups.
Why it matters
Potential benefit: If successful, this could allow more women to sip carbohydrate drinks before elective caesarean to reduce hunger and improve recovery without increasing stomach volume or aspiration risk.
How similar studies have gone: Prior studies show that 'Sip Til Send' with water is safe and that carbohydrate drinks reduce preoperative hunger, but directly comparing sipped carbohydrate drinks to water with bedside gastric ultrasound is a novel combination.
