Fluid and ondansetron before anesthesia to prevent low blood pressure
This study tests whether giving fluids and a medicine called ondansetron before general anesthesia helps prevent blood pressure drops during surgery. If you qualify, you may receive a simple, safe approach to keep your blood pressure stable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- Your surgery is planned (not emergency) and involves general anesthesia, and is not heart or obstetric surgery.
- Your overall health is rated as ASA class I–III (healthy to mild or moderate systemic disease).
- Your blood pressure is adequate (mean arterial pressure 60 mmHg or higher) before anesthesia.
- You are not taking certain blood pressure medications (ACE inhibitors or ARBs) on the day of surgery.
- You do not have significant heart failure, kidney failure, liver failure, or a known allergy to ondansetron.

This trial looks at how a breathing maneuver during surgery can safely lower blood pressure and help doctors decide whether you need extra fluids. It may help guide your care during surgery to keep you stable and reduce complications.
This study uses ultrasound to check blood vessels before surgery to predict if blood pressure might drop during anesthesia. It aims to help doctors keep patients safer during abdominal surgery.
This study tests whether a special computer tool (called the Hypotension Prediction Index) can help anesthesiologists keep your blood pressure from dropping too low during major abdominal surgery. By using this tool, doctors hope to reduce the risk of low blood pressure during surgery and improve safety for older frail adults.
