Summary

This trial looks at whether giving angiotensin II intravenously can help with low blood pressure during anesthesia in adults, which is common and can cause problems.

Who is the study for?
This trial is for adults with high blood pressure who are undergoing general anesthesia and have been treated with blood pressure medications, including ACE inhibitors or ARBs, for over two months. It's not suitable for individuals with asthma, severe obesity (BMI > 40), pregnant women, those with a history of serious heart or lung conditions, stroke, deep vein thrombosis or difficult airways.
What is being tested?
The study is testing the effectiveness of intravenous Angiotensin II as a treatment for low blood pressure that occurs during general anesthesia in patients who already have high blood pressure and are on certain medications.
What are the potential side effects?
Potential side effects may include reactions at the injection site, changes in heart rate or rhythm, allergic reactions to the drug components, kidney function alterations and possible increases in blood pressure.
