Optimizing blood volume before surgery using heart ultrasound
Part of Heart & circulation clinical trials.
This trial tests whether using a heart ultrasound before surgery can help doctors better manage your blood volume. If you are having surgery under general anesthesia and have a higher risk of heart problems, this study may help improve your safety.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- You must be having surgery under general anesthesia
- You must have a moderate to high risk of heart issues within 30 days after surgery
- Your physical status must be ASA class 3 or 4 (meaning you have a serious health condition)
- You cannot be pregnant or breastfeeding
- You must not be taking certain blood pressure medications (ACE inhibitors or ARBs) on the day of surgery
