The Claim
In adults undergoing hip or lower extremity orthopedic surgery under spinal anesthesia, preoperative oral intake of 200 mL of 10% dextrose solution does not significantly reduce postoperative nausea or vomiting, despite reducing anxiety, indicating that anxiety reduction alone is insufficient to prevent postoperative nausea or vomiting in this population.
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 adults having hip or leg surgery with spinal anesthesia, drinking 200 mL of a 10% dextrose solution before surgery reduces anxiety but does not reduce postoperative nausea or vomiting.
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) does not significantly reduce postoperative nausea or vomiting despite reducing anxiety, suggesting that anxiety reduction alone is insufficient to prevent these symptoms in this population.
Drinking a sugary solution before surgery triggers the gut to release a hormone that improves blood sugar control and shuts down the body's stress response, which lowers anxiety but does not stop nausea or vomiting after surgery.
What the research says
1 studyDrinking a sugary drink before surgery made patients feel less anxious, but it didn’t make them feel less sick to their stomach or stop them from throwing up. So, being less anxious doesn’t seem to be enough to prevent nausea after this kind of surgery.
