Ultrasound-guided fluid and ondansetron before general anesthesia
Part of Heart & circulation clinical trials.
This trial tests whether using a bedside ultrasound to guide IV fluids, along with a nausea medicine called ondansetron, can prevent blood pressure from dropping after starting general anesthesia. It may help people stay more stable during elective surgeries.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be older than 18 years
- Plan to have elective surgery (not heart surgery and not during pregnancy) using general anesthesia
- Your overall health should be mild to moderate (ASA I–III) as judged by the anesthesia team
- Before anesthesia starts, your blood pressure is not too low (mean arterial pressure not below 60 mmHg)
- You should not take ACE inhibitors or ARBs on the day of surgery
- You should not have severe heart failure (ejection fraction under 40%) or serious kidney or liver failure

This trial tests whether a medicine called ondansetron (commonly used for nausea) can help prevent low blood pressure during spinal anesthesia for planned C-sections. If you are a healthy pregnant woman with a single baby at full term and scheduled for a C-section, you may be able to join.
This trial tests if adding ondansetron to standard spinal anesthesia during hernia surgery can provide better pain relief. It may help you need less pain medicine after the procedure.
This trial tests whether a nausea medicine called ondansetron helps people feel better and lets doctors work more efficiently during a camera test (endoscopy) for upper GI bleeding. If you need an emergency endoscopy for bleeding, ondansetron may reduce discomfort.
This study tests if giving hydrocortisone (a type of steroid) or ondansetron (an anti-nausea drug) before spinal anesthesia can better prevent low blood pressure during surgery for your belly or lower leg.
This trial tests if giving ondansetron before spinal anesthesia can prevent itching that often happens after a C-section. It may help you feel more comfortable during recovery.
This trial tests whether ondansetron can help people with atrial fibrillation (an abnormal heart rhythm) around the time of elective catheter ablation. It may improve the safety or effectiveness of the procedure by targeting a pathway involved in heart rhythm events.
