The Claim

Preoperative oral dextrose intake (200 mL of 10% solution) in adults undergoing hip or lower extremity orthopedic surgery under spinal anesthesia is associated with sustained reductions in pain and anxiety scores up to 24 hours postoperatively.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Adults who drink a 200 mL solution of 10% dextrose before hip or leg surgery under spinal anesthesia experience lower pain and anxiety levels for up to 24 hours after surgery compared to those who do not.

See the scientific wording

In adults undergoing hip or lower extremity orthopedic surgery under spinal anesthesia, preoperative oral dextrose intake (200 mL of 10% solution) is associated with sustained reductions in pain and anxiety scores up to 24 hours postoperatively, suggesting a prolonged benefit to subjective recovery beyond immediate perioperative effects.

Why this might work

Drinking a sugary solution before surgery lowers blood sugar stress, which tells the body to stop releasing stress hormones and inflammatory chemicals. This calms the nervous system, reduces pain signals, and lessens feelings of anxiety for up to 24 hours 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

    People who drank a sweet drink before their hip or leg surgery felt less pain and anxiety during and after surgery—even 24 hours later—compared to those who didn’t drink anything. This suggests the sugary drink helped them feel better for a longer time.
