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 has no significant effect on perioperative nausea or vomiting compared to standard fasting, as measured by Visual Analogue Scale in adult patients.
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.
Giving adults a 200 mL drink of 10% sugar water 2 to 3 hours before hip or leg surgery under spinal anesthesia does not reduce nausea or vomiting after surgery compared to not eating or drinking before surgery.
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 shows no significant effect on perioperative nausea or vomiting compared to standard fasting, as measured by Visual Analogue Scale in 70 adult patients, indicating it does not serve as an effective antiemetic in this context.
Drinking a sugary solution before surgery raises blood sugar, which tells the pancreas to release insulin. Insulin then calms the body’s stress response, lowers inflammation, reduces hunger and thirst, and eases anxiety. None of these changes affect the brain areas or nerves that trigger nausea and vomiting, so the sugary drink does not prevent those symptoms.
What the research says
1 studyThe study found that drinking a sugary drink before hip or leg surgery didn’t make patients feel less nauseous or vomit less than those who didn’t drink anything. So, the sugary drink doesn’t help with nausea after surgery.
