The Claim

Preoperative oral intake of 200 mL of 10% dextrose solution 2–3 hours before hip or lower extremity orthopedic surgery under spinal anesthesia is associated with significantly lower perioperative thirst and pain scores compared to standard fasting, as measured by Visual Analogue Scale in adult patients.

Support is ahead, but a single strong opposing study can change this.

In plain English

Patients who drink 200 mL of a 10% sugar solution 2–3 hours before hip or leg surgery under spinal anesthesia report lower thirst and pain levels during surgery compared to those who fast, as measured by a standard pain and thirst scale.

See the scientific wording

Preoperative oral intake of 200 mL of 10% dextrose solution 2–3 hours before hip or lower extremity orthopedic surgery under spinal anesthesia is associated with significantly lower perioperative thirst and pain scores compared to standard fasting, as measured by Visual Analogue Scale in 70 adult patients, suggesting a clinically meaningful improvement in subjective comfort during the perioperative period.

Why this might work

Drinking a sugary solution before surgery lowers the body's stress signals, reduces inflammation, and balances fluid levels, which makes the mouth feel less dry and the body feel less pain after surgery.

  1. Study: The effect of preoperative oral carbohydrate intake on perioperative well-being in patients undergoing hip and lower extremity orthopedic surgery under spinal anesthesia: a randomized controlled trial

    Patients who drank a sweet drink before their leg or hip surgery felt less thirsty and less pain afterward than those who didn’t drink anything, and the study proved it with clear measurements.
